Rotary hearth furnace

In rotary hearth furnaces, the material is heated to temperatures between 500 and approx. 1,350°C. Typical furnace capacities are approx. 0–10 t/h. Regenerative burners and hot-air burners are used for heating rotary hearth furnaces.

Rotary table furnace

In rotary table furnaces, the material is heated to temperatures between 500 and approx. 1,350°C. Typical furnace capacities are approx. - 0 t/h. Regenerative burners and hot-air burners are used for heating the rotary table furnaces.

Pusher-type furnace

In pusher-type furnaces, the material is heated to temperatures between approx. 1,100 and 1,300°C. Typical furnace capacities are approx. 50- 50 t/h. Regenerative burners and hot-air burners are used for heating pusher-type furnaces.

Walking hearth and walking beam furnace

These furnaces achieve throughputs of up to 500 t/h at a discharge temperature of 1,250°C and are used for reheating slabs and billets in front of hot mills for plates, rails, sections, wires, and various long products. Regenerative burners and traditional hot-air burners are used to heat the product.

Tunnel furnace

Positioned between the caster and the mill in a CSP line these furnaces provide buffer time between the caster and mill operations.  Allowing time for soaking and temperature uniformity of the bar are critical aspects of a tunnel furnace.  Traditional hot-air or recuperative burners maintain steel temperatures for rolling and transport rolles convey the product to the mill.  

Roller hearth furnace

In roller hearth furnaces, the material is heated to temperatures of up to 1,100°C. Typical furnace capacities are approx. 5-80 t/h. Recuperation and regenerative burners as well as hot-air burners are used for heating roller hearth furnaces.

Double walking beam furnace

In double walking beam furnaces, the material is heated to temperatures of up to 1,150°C. Typical furnace capacities are approx. 5-80 t/h. In addition to hot-air burners, recuperation burners are increasingly being used for heating double walking beam furnaces.

Car bottom annealing furnace

Designed as heat treatment furnaces for a temperature range of 100 to 1,150°C for heat treatment in forging mills, foundries, and heat treatment-only plants in the steel industry as well as in the non-ferrous metal industry. Maximum charge: 500 t.

Hood-type furnace

This furnace type is used for the entire process of forging through heat treatment for special applications. Working temperature range from 00 to approx. 1,150°C. The hood or cover is moved automatically with a traveling crane or other suitable lifting device.

Heat treatment pit furnace

These plants are used for the entire process of forging through heat treatment for special applications. Temperature range from 700 to approx. 1,150°C. The covers are moved automatically with a traveling crane or other suitable lifting device.

Car bottom forge furnace

Designed as heat treatment furnaces for a temperature range of 100 to 1,150°C for heat treatment in forging mills, foundries, and heat treatment-only plants in the steel industry as well as in the non-ferrous metal industry. Maximum charge: 500 t.

Chamber and double-chamber furnace

This furnace type is used for heating steel in forging and rolling mill plants as well as for heat treatment. Working temperature range from 500 to approx. 1,300°C. In the heat treatment process, chamber furnaces are often combined with quenching baths and charging installations for automatic operation of the entire heat treatment process (hardening, tempering, etc.).

Pit furnace

This furnace type is used for heating steel ingots and is designed as a large chamber furnace or as a high quality single-chamber pit furnace, especially for heating highly sensitive stainless steels. Temperature range from 700 to 1,300°C. Charging weights between approx. 5 and 15 t.

Stainless steel strip annealing furnaces - CAPL, HAPL, BAL processing lines:

To process stainless steel coil with the follow cycles:  Hot and cold annealing and pickling as well as bright annealing with strip heat cycles up to 1,250°C.

Carbon steel strip annealing furnaces for CGL, CAL processing lines

To process hot rolled and cold rolled coils with dedicated heat cycles from mild steel up to 3rd generation AHSS, through proprietary cup-shaped direct fired burners and/or radiant tubes heating/soaking chambers, proprietary powerful differential rapid cooling jet @ 5% H2, as well as after pot cooling and post treatment tower.

Melting and Holding furnaces

Used in the processing of aluminum in various alloys the melting furnace is used to liquify scrap and combine it with virgin aluminum.  After being transfered to the holding furnace through a launder the aluminum is temperature homoginized and final alloying takes place.  The tilting holder pours the liquid aluminum into the casting equipment under tightly controlled conditions.
