Steel strap quenching and tempering production line
——The use of lead quenching process, obtain sorbite, bainite, martensite organization
After quenching and tempering, cold-rolled alloy steel of high strength carbon steel strip obtained the high strength, good toughness and ideal hardness, products widely used in metal tools, springs, tool, woodworking band saw, automotive clutch plates, clocks and watches clockwork, the locks, shoe, textile equipment, packaging strip and other various industries .
Steel strap quenching and tempering production line (hereinafter referred to as the production line) is mainly composed of heating furnace, isothermal quenching furnace, tempering furnace, welding machine, trimming machine, before the loop and after the loop ,uncoiler, coiler, electronic control system and auxiliary system.
Due to heating and cooling in protecting atmosphere, so the surface of steel strip can be kept light without oxidation and decarburization.
    Full range of equipment using frequency control, temperature closed-loop adjustment, PLC control, human-computer screen connected, according to market demand for flexible adjustment of product varieties and specifications, in this production line can produce different intensity levels and different surface state of high-strength steel strip.
Production line features:
1, the heating method: Using resistance furnace heating, cover an area of an area small, high thermal efficiency;
2, the cooling medium: Using a metal liquid quenching cooling quenching process (lead bismuth alloy); according to the user's need to produce light without oxidation, micro-oxidation and the blue surface of high-strength steel strip;
3, the control mode: computer programming, precise control of furnace temperature, strip temperature, strip speed, the pressure and flow of the protect gas , the pressure and flow of the cooling medium, to ensure that the microstructure and mechanical properties of the steel strip ;
4,Quenching organization: According to the requirements of mechanical properties of the final product to obtain the microstructure of martensite, bainite, sorbite, through continuous change or isothermal transformation ;
5, product variety: *5Mn, *0 #, *0 #, T8A, of T*0A, T*2A, SK4, SK5, SK7, *0CrV, *0Mn, *0Mn2, *0Si2Mn special steel strip;
6, product specifications: a thickness of 0.5 to 2.0mm; width *0 to **0mm (width less than *0mm can strip handle);
7, the mechanical properties: tensile strength: ***0 ~ ***0MPa; elongation: *2%; hardness: RHC*5 ~ *0.
