What is characteristics of oxygen cutting steel plate?

1. Relationship between oxygen cutting accuracy and cutting quality
Oxygen cutting accuracy is very important for steel plate cutting. It refers to the error between the geometric dimension of the workpiece after cutting and the dimension required by the drawing. The smaller the error, the higher the cutting accuracy, the better the cutting quality. In addition, for cutting quality, there are three basic elements, namely cutting gas, cutting speed and cutting nozzle height.

2. Causes of cutting cracks
In steel plate cutting, the cutting crack mainly refers to the crack on the cutting section, or the pulsating crack in the internal part of its accessories, or the visible crack on the cross section, no matter which, it is a kind of cutting crack.
The reason of cutting crack is that the carbon content of steel plate is too high, the preheating temperature of workpiece is not enough and the cooling time of workpiece is too short.
