The quality evaluation of plasma arc BV AH32 steel plate cutting includes the following aspects:
Incision width: the dimension of the widest part of the incision, usually 0. 15-6mm. If the cutting width is not appropriate, it will cause waste of BV AH32 steel plate, reduce cutting speed and increase energy consumption.
Surface roughness of BV AH32 steel plate: mainly used to determine whether rework is needed after cutting.
The amount of slag hanging: mainly observed by naked eyes, divided into four grades: none, mild, moderate and serious.
The surface structure and mass transfer of silicon under boron nitride chip diffusion were observed and analyzed by infrared transmission spectroscopy, ellipsometry and four probes.
The formation and development of the surface system of BV AH32 steel plate is related to specific diffusion conditions (temperature, time, atmosphere, source silicon spacing). The analysis of surface process of BV AH32 steel plate shows that the surface structure is the result of reaction diffusion.
