What are the preheating and basic requirements for steel plate cutting?

1. Basic requirements for steel plate cutting and after steel plate cutting
When cutting steel plate, it is required to cut according to the requirements of the drawing, and can be cut on demand to meet different processing requirements of users. After the steel plate is cut, the cutting size should be accurate without any deviation. The cutting surface should be smooth and smooth, and the cutting edge should be neat and free of burr and other defects. It can be used directly without the user's secondary processing. In addition, it can also reduce processing costs.

2. Preheating of steel plate before cutting
There are some instructions for preheating before steel plate cutting, which is specifically as follows: if flame cutting is adopted, steel plate shall be preheated under normal conditions, and preheating temperature is determined by steel plate quality grade and steel plate thickness, and preheating method is determined by actual situation and preheating requirements. In addition, the whole steel plate interface should be heated evenly without local overheating. If overall preheating is not possible, local preheating can be carried out.
