How to prevent SM400A carbon steel plate sheet, steel plate cutting cracks? 1. Preheat the steel plate before cutting, and the preheating temperature depends on the quality grade and thickness of the steel plate. However, it needs to be heated evenly. 2. The cutting speed is reduced appropriately, but its reliability is not as good as preheating. It is suggested to preheat the cutting belt with flame gun cavitation several times before cutting, and the preheating temperature should reach about 180℃.
