Heat treatment

We carry out the heat treatment in 12 gas furnaces and four quenching tanks. The technological process is computer-controlled and documented by heat treatment records.

Main types of heat treatment

  • annealing
    • normalisation
    • soft annealing
    • stress relieving
    • solution annealing
    • homogenisation, simulated annealing
  • quenching of carbon and alloy steels
  • quenching of tool steels at an austenitization temperature of 1,100 °C
  • quenching of special steel

Cutting

We carry out the cutting on four band saws, the maximum cross section of material is 1,750 × 1,750 with 60 t maximum weight.

Specifications
Maximum dimensions 1,750 x 1,750 x 15,000 mm
Maximum weight 60 t
Technical options Horizontal and vertical cut

Flame cutting

We carry out the flame cutting using two Messer flame cutting machines with the possibility of preheating of material in two furnaces. We can carry out the heat treatment after the flame cutting (cooling, qualitative heat treatment) in the quenching section.
