Furnace floor

     Furnace floor plate material can be divided according to furnace silicon carbide furnace floor, heat-resistant steel furnace floor and stainless steel oven floor and so on. According to uses can be divided into wear resistant floor furnace, heat treatment furnace floor, box-type electric floor, floor furnace heat treatment furnace, trolley furnace floor, floor resistance furnace, Pit furnace floor, mesh belt furnace floor and so on, fan oven plate, combination oven floor. Depending on the furnace floor furnace power can be classified into the furnace floor 15KW, 30KW floor furnace, 45KW floor furnace, 60KW floor furnace, 75KW floor furnace, 90KW floor furnace, 100KW floor furnace, 120KW floor furnace, 150KW furnace floor and so on.

     Heat-resistant steel casting furnace floor is usually made of heat-resistant steel, the material can be divided into Cr-Mn-N (suitable for 850 ℃ or less), 3Cr24Ni7SiNRe, suitable for 850 ℃ ~ 1050 ℃ (on behalf of high-chromium nickel steel), 1Cr25Ni20Si2 fit at 1050 ℃ ~ 1200 ℃.

     Floor furnace for carrying high-temperature annealing treatment of the workpiece. Zhou furnace floor and furnace floor life stress related. Simulation of thermal stress during high-temperature annealing furnace floor at the furnace floor temperature changes using the finite element method. In the high-temperature annealing process due to the internal temperature of the furnace floor unevenness, the maximum thermal stress is always generated in the outer edge of the oven floor. Tensile stress is the root cause cracks.

     In the cooling process, the edge of the furnace floor by tensile stress, and because the high temperature, the lower limit of the furnace floor strength, the most prone to cracking. At the same temperature load, to simulate different structural parameters of the furnace floor to thermal stress maximum week, looking for the furnace floor structure parameter optimization. Reduce corrugated edges and column radius can be advantageously reduced thermal stress generated by the outer edge of the oven floor.
