Roller hearth continuous furnace in Russia

Tenova LOI Thermprocess received an order from JSC Pervouralsk Pipe Plant, Russia, for a new roller hearth continuous furnace system for bright annealing stainless steel pipes.

Tenova LOI Thermprocess was recently awarded an important order from the Joint Stock Company Pervouralsk Pipe Plant, Russia, for the delivery and installation of a continuous roller hearth system for stainless steel pipe.

This extremely flexible furnace type is characterized by uniform heating, a definable holding time and subsequent material-specific cooling. The high temperature uniformity and the low energy consumption of these systems ensure reproducible processes, which can be precisely adapted to the desired heat treatment of the material. The drive sections can be optimally matched to the respective annealing process.

The heat treatment system for the JSC Pervouralsk Pipe Plant is designed as a roller hearth furnace for the bright annealing of 2,000 kg/h of austenitic stainless steel and nickel-based alloy pipes. The solution annealing of these high-alloy steel grades is carried out in the temperature range of max. 1,100 °C to 1,200 °C. The tubes are heat-treated in this continuously operating roller hearth system using a 100% hydrogen atmosphere as process gas.

In addition to the equipment, the scope of delivery also includes installation and monitoring of commissioning by specialists from Tenova LOI Thermprocess.
