The laser cutting technology for S690QL material

As the thickness and hardness of S690QL material increase, the tendency to crack at the cutting edge increases. In order to prevent the S690QL material from cutting cracks, preheating should be carried out before S690QL material cutting. Special attention should be paid to preheating to make the entire S690QL material interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole S690QL material cannot be preheated, the partial preheating method can be used instead.

The application of AR400 abrasion resistant steel plate: S690QL material, AR400 abrasion resistant steel plate is mainly for wear exposed structures use, such as protective pads, shell walls for prospectors and bulldozers. AR400 abrasion resistant steel plate is also used to fabricate the supporting or reinforcing plate, the cutting plate for truck rollover, mixing elements and conveying elements, chute grooves, machine tools, crushers and shredders, waste briquetting presses, blades, paving abrasives and agricultural machinery.
