What are the precautions for preheating steel plate before cutting?

The preheating before cutting the steel plate, its specific is: if it is the flame cutting this cutting way, then, under normal circumstances, the steel plate to preheat, and the preheating temperature is determined by the quality grade of the steel plate and the thickness of the steel plate, the preheating way is determined by the actual situation and preheating requirements.

In addition, the entire plate interface should be heated evenly, there can be no local overheating and other phenomena. If overall preheating is not possible, local preheating can be performed.

From a professional point of view, it is to decide the cutting method of steel plate first, and then to decide which steel plate cutting equipment to use, because different methods of steel plate cutting correspond to different equipment.
