Advantages of steel plate heat treatment production line:
1. The workpiece can be heated evenly ; the temperature can be precisely controlled.
2 , steel plate heat treatment production line heating speed, no oxidation and decarbonization, high heating efficiency.
3 , sheet electric heating equipment has low energy consumption and high thermal efficiency.
4 , steel plate heat treatment production line production operation is simple, flexible operation, high degree of automation.
5. The plate after treatment by the steel plate heat treatment production line has no deformation, no crack and high hardness.
Advantages of heating uniformity of steel plate heat treatment production line
The plate heat treatment production line adopts the fixed quenching method. Through reasonable waterway and structural design, the uniformity of the spray quenching can be ensured, and the high flatness can be obtained by the pressure of the indenter to avoid the quenching heat treatment production line of the soft point steel plate. Uniform heating, hardenability steel heat treatment production line through computer simulation technology, simulate the shape change of steel plate quenching heat treatment process, reasonable design of waterway and nozzle layout to ensure uniformity of spray quenching. The steel plate quenching heat treatment production line is calculated according to the production capacity. The steel plate heating in the furnace can be oscillated in the furnace, thereby reducing the length of the heating furnace, reducing the input and energy consumption, and achieving the best economicalization of the steel plate.
Advantages of steel plate heat treatment production line :
1 , PLC control, full line intelligent, automated
2 , the automatic control system has material tracking, temperature control, protective atmosphere metering control, heat balance data analysis, fault alarm, steel plate quenching heat treatment production report and other functions.
