U-shaped steel quenching and tempering heat treatment production line working principle
Place the u-shaped steel on the bed of the loading end, and drive it through the quenching induction coil at a constant speed to heat it to 840.
At 850 ° C, it is quenched by rapid spray water cooling of the overspray, and then heated into a resistance furnace to 540-550. C is tempered and finally discharged to the lower rack through the unloading mechanism to complete the quenching and tempering process.
