In order to improve the quality of steel materials in the steel industry, it is very important to install a high-pressure water phosphorus removal system on the rolling line. If you want the phosphorus removal system to be stable and circulate high-pressure water to remove phosphorus, the installation of a self-cleaning filter is very necessary. This self-cleaning filter has a large flow rate and a high degree of automation. It can efficiently intercept more than 98% of impurities in phosphorus removal circulating water and improve the use efficiency of circulating water by 60%. Extend the service life of the high-pressure pump of the phosphorus removal system by 5-8 years.
