Melting furnaces

Generally, single-chamber furnaces come at comparatively low investment cost. That's because the furnace design is simple: either rectangular or round, depending on your individual application.

Rectangular furnaces feature a front door across the entire furnace width. This ensures full access during charging and skimming. Furnaces are designed either for hydraulic tilting (such as casting furnaces) or as stationary types.

Typically, secondary recyclers use the URTF type for melting dross and low-grade scrap (with organic impurities >10%) or material with a high iron content. Available here is a wide range of sizes from 3 to 14 m3 (6 to 27 tons) and melting rates from 1.5 to 6 tons per hour. You can also choose from a broad tilting range of between -20 and +40°. As a unique feature, the furnace can be operated at various tilting angles from -20 to -10°. The backward tilt of -20° facilitates quick charging. You benefit from the high degree of automation for charging, melting, tapping, and slag tilting. That's because it takes only one operator plus one supervisor per shift to operate the furnace. You can cut costs even further because the oxy-fuel burner system comes with short cycle times and correspondingly high melting rates.

Here you see a furnace specifically designed for melting loose swarf and light-gage scrap. It's the result of extensive in-house R&D aimed at achieving outstanding cost- effectiveness and green operation.
