AMAG, Austria, has commissioned a tiltable melting and casting furnace from Hertwich Engineering, Austria. The furnace, type

SGO-70+, has been developed jointly by the two companies. The capacity of the furnace is 70 tons, the nominal melting rate is designed for up to 12 tons per hour. As such, it is the largest combined melting and casting furnace that Hertwich has delivered to date and also the largest of its type at AMAG.

In comparison with conventional furnaces on the market the

SGO-70+ furnace from Hertwich offers additional features which substantially extend the area of application to different scrap types.

Efficient heating with two regenerative burner pairs results in a specific gas consumption for melting operation of less than

550 kWh per ton.

The furnace is equipped with oxygen measurement as well as separate natural gas and combustion air regulation to ensure clean combustion in terms of stringent emission regulations.

An electromagnetic pump ensures proper collection of chips and alloying elements as well as good melt circulation, constantly high melting capacity and homogenous temperature distribution in the furnace.

The supply package additionally includes a railbound pusher-type charging machine with a capacity of 25 tons, to efficiently load the furnace within a few charging cycles.

Production started in January 2013.

SMS Siemag AG and SMS Meer GmbH are both companies of SMS group which, under the roof of SMS Holding GmbH, consists of a group of companies internationally active in plant construction and mechanical engineering for the steel and nonferrous metals industry.
