The raw material of boron carbide nozzle is made of cast iron pipe


Boron carbide nozzles previously used cast iron tubes as the raw material for the nozzles. Ceramic nozzles appeared in the early 20th century. Tungsten carbide nozzles appeared in the 1930s, in 1870. This is now the tungsten steel nozzle. In the 21st century, people pay more and more attention to nozzles. Boron carbide nozzles have been widely used in the sandblasting industry. It is just that some manufacturers use low-quality tungsten steel nozzles to replace boron carbide nozzles in order to save equipment costs. A variety of heavy metal ultra-fine powders with boron carbide as the main material have been subjected to high-temperature hot-pressing technology to have high temperature resistance, wear resistance, corrosion resistance and light weight , High hardness, and hardness second only to diamond, flexural strength 40kg / cm2, physical and mechanical properties of boron carbide nozzle: hardness HRA & nbsp; 92-94. Compressive strength 240kg / cm2, the investment made for the entire system will get a corresponding return , The service life is twice that of ordinary cold pressed sintered hard alloys (tungsten carbide) and silicon carbide. Blast cleaning efficiency and running cost of the entire blasting operation. Buyers should be more aware of the life of the nozzle in the process of selecting the boron carbide nozzle. The blasting work has a high cleaning efficiency, reduced cleaning costs, and the enthusiasm of the blasting work can be fully exerted. The nozzle is not used well, even if the supporting equipment in the blasting system is efficient, the effect will be greatly reduced, the work efficiency is not high, the cleaning cost will rise, and the enthusiasm of the blasting worker will be frustrated.
