]]>
Jiangsu ChangBao Precision Steel Tube Co., Ltd based in Changzhou in Jiangsu Province, China, has awarded SMS group the contract to supply a new, state-of-the-art PQF® (Premium Quality Finishing) seamless tube plant and related automation. Particular highlights of the scope of supply include various performance modules and a KR I 35/45 CNC groove dressing machine. This highly automated plant will enable ChangBao to meet the growing demand for precise, high-strength tubes on the local market.

The PQF® ordered will be used to produce tubes within a diameter range of up to 6 5/8 inches and wall thicknesses of between 4 and 20 millimeters. Its annual capacity is 300,000 tons of tubes. These are used in oil and gas production (OCTG tubes) and must satisfy very high quality and tolerance requirements in accordance with API standards.

With the BCO-type PQF® plant (Bilateral Change-Over), the stands are changed at both sides of the mill. The compact, easily accessible construction enhances the user-friendliness of the plant. The drive is simpler in design and is easier to service. In addition, the hydraulic capsules (hydraulic adjustment) are positively connected to the mill frame. This ensures the rolling forces are distributed symmetrically over the mill, resulting in a further significant improvement in wall thickness variations. This increases both the efficiency and flexibility of the mill.

The order also includes the full automation of the machinery and plant sections, as well as state-of-the-art laser technology for measuring the wall thicknesses downstream of the PQF® and the stretch reducing mill (SRM). What’s more, the CaliView® measuring system developed by SMS group allows for fast, inline calibration of all rolling mills, and so guarantees the perfect alignment of the mill line over a period of time. A networked, CNC-based groove dressing machine (KR) for high-precision machining of the SRM stands will also be supplied.

The use of LASUS® technology means the otherwise commonly applied radioactive isotope measuring technique can be replaced by a safe laser technology, which is extremely environmentally friendly to operate and ensures monitor control with the PQF®-SecControl-Technology® as well as front and tail end sharpening in real time with the FTS system.

Any yield losses are minimized using the latest modules in the CARTANEO technology system. The well-known functions CEC (Crop End Control for reducing thick ends), WTCA (Wall Thickness Control, Average), and WTCL (Wall Thickness Control, Local) have been significantly improved thanks to self-learning algorithms (Artificial Intelligence, or AI).

With this investment ChangBao is banking on ultra-modern, highly stable tube production. The lower material stress allows the product range to be extended to include even thinner-walled dimensions and higher-alloy steel grades. The high level of digitalization of all equipment was what convinced the customer to be well equipped for the future.

The new seamless tube plant is scheduled to be commissioned in the first quarter of 2020.

]]>
Ternium del Atlántico SAS, has placed an order with SMS group for the supply and installation of the VCC® technology (Vertical Compact Coiler) for its bar mill in Palmar de Varela, Barranquilla, Colombia.

SMS group’s VCC® is today’s state-of-the-art solution for producing compact and torsion-free coils, and is now increasingly in demand by rebar processors. The compact coil is a crucial step forward in improving the pack-up quality of the final product. These coils have preselected dimensions that, thanks to VCC®, remain consistent for all products processed on the same line. At the same time, the compact coil size is ideal for storage, transport and handling. This is particularly beneficial when coils are reworked next to construction sites, where there is a build-up of rebar stirrups and other concrete reinforcing structures, especially in metropolitan areas with many space constraints. These are the preconditions that convinced Ternium to integrate this VCC® technology into the existing bar mill.

Once in operation, the plant will produce rebars from eight to 16 millimeters in diameter at speeds of up to 35 meters per second. The output will be 120 tons per hour with a coil weight of up to three tons.

One of the most important features of VCC® is its method of coiling the bar directly in the vertical position. Plant operators can therefore eliminate the need for turning manipulators and at the same time reduce the process cycle time, as all coils are formed in the final position. The coils are ready to be stored immediately once coiling has been completed and the coils have cooled down.

This order sets the score to 20 VCC® units supplied by SMS group worldwide since 1998 and is another important achievement demonstrating again SMS group’s expertise and position as a reliable and leading partner in the world of metals for plant supply, installation, startup and commissioning. The result is 543 facilities for wire rod, SBQ and special applications, bars and merchant products the company has supplied since 1950.

Commissioning of the new MT 5000 closed-die forging press is scheduled for Q4 2019. The new forging press will enable Musashi Europe to produce large rotationally-symmetric forgings for passenger cars and truck applications in a highly efficient production process. With the new eccentric forging press, which features a MEERtorque® servo drive, forging is precise, reliable and fully automatic.

The MT 5000 is one of the latest generation of eccentric presses from SMS group. The eccentric shaft and the flywheel are directly driven by dynamic torque motors. This type of drive separates the pure ram motion from the forging energy supply, and combines the advantages of servo presses with those of presses featuring a flywheel and conventional clutch-brake combination. This means the forging process is both highly energy-efficient and resource-friendly. The energy generated during the deceleration phase can be used for the re-acceleration of the flywheel.

Thanks to the reduced number of mechanical components, Musashi Europe benefits from considerably lower maintenance and inspection costs. What’s more, sections of the MT press casing can be easily opened to offer the best possible access. Furthermore, the utilities are supplied via a central energy column, which also provides particularly maintenance-friendly access.

The construction of the robust, FEM-optimized press housing is based on the proven split tie-rod design. Extremely large press windows offer perfect automation capability and allow for easier changes of the die and holder. To enable individual dies to be replaced, the MT 5000 is equipped with a die change arm, which is fitted to the press housing. The integrated die spraying system cleans, cools and dries the dies in precise doses, to achieve maximum forging quality and increase the service life of the dies.

]]>
Nanjing Iron and Steel Group Co., Ltd., a leading Chinese steel producer with approximately ten million tons of steel produced per annum, has awarded SMS Concast AG an order to upgrade the four strands of continuous caster CCM4 at its Nanjing plant No. 2. The targets of the project are to improve product quality and productivity and also to increase flexibility in the processing of a vast steel grade portfolio and to reach an annual production of more than 800,000 tons of blooms.

The four-strand continuous casting machine with nominal radius of 12 meters will cast two bloom section sizes, namely 250 x 300 and 320 x 420 millimeters. The product mix will include a large proportion of high-carbon grades like bearing and spring steels and the full range of steel grades to serve the automotive industry. This product portfolio will allow greater production flexibility and responsiveness to the market demand.

The casting machine will be equipped with the latest technological design to make this caster one of the most modern installations worldwide. Features, like dynamic mechanical soft reduction (DMSR) shall improve the inner quality of the blooms by means of soft and hard reduction modules designed to reach the necessary reduction ratios for an accurate control of core porosity and segregation.

The complete control of the soft/hard reduction (DMSR) system is delegated to the COOL real-time solidification model. This online simulation tool is a proprietary system developed by SMS Concast. It dynamically calculates the temperature profile along the entire strand and defines the roll gap and the reduction forces in the respective modules of the straightening unit. The spray cooling is also dynamically readjusted in accordance with the calculated cooling profile.

In addition to the DMSR system, the modernization project includes other technological and digital solutions such as CONFLOW tundish stopper mechanism for a precise control of the steel flow to the mold, INVEX® mold tube technology with the latest mold cooling features and a hydraulic tandem oscillation system allowing several oscillation parameters. The electromagnetic mold and final stirrers (CONSTIR M-EMS and F-EMS) together with the SMS Concast CONSTIR-MWS tool (modulated wave stirring) optimize stirring efficiency with an energy saving of 30 percent and more. The list of technological packages is rounded up by air-mist spray cooling and a bloom deburring technology. The installation of a robot-type slide gate manipulator will be also foreseen to increase safety and unmanned operation on the casting floor.

The electrical and automation system has the prime purpose of automatically controlling the operation of the caster (no-man casting). At the same time, the Level 2 computer system tracks and records all parameters relevant to bloom quality and provides a detailed cast report for each bloom. This preventive software module includes automatic sample cutting, slice by slice identification, computerized bloom tracking, a heat extraction mode, optimized residual length calculation and equipment life time recording.

In order to minimize shutdown times, particular attention was paid to project planning and delivery schedule in order to achieve quick implementation. The modernization is scheduled for completion in the fourth quarter of 2019.
