What is the high chromium alloy material of the special pump for filter press

        The biggest factor affecting the price of filter press special pumps is the material. Good materials can prolong the service life of the pump. Although customers pay a little higher when they buy, good materials are relatively more wear-resistant in the later period. Use of accessories Long life, so good material filter press pump also brings great benefits to customers.


At present, the most special pumps for filter presses are made of high chromium alloy materials, so what is high chromium alloy, the following is a brief description for customers:
High chromium alloy (white cast iron). At present, most domestic enterprises use wear-resistant materials as the main part of the intermediate frequency electric furnace, which is reasonably matched by high-quality scrap melting. After the chromium alloy material, it is combined with molten iron microalloying and quenching. The last unique mold is a sand mold casting molding process; then through high temperature quenching and tempering treatment, a martensite matrix is ​​obtained to achieve high hardness and wear resistance.
The widely used high chromium alloy powder is used in cement, metal mines, coal slurry thermal power, chemical engineering, ceramic coating, glossy paper, magnetic materials, etc. In deep processing. Products with high hardness, low wear, good toughness, and enhanced wear resistance.
There are dozens of different materials in chemical composition, from low to high chromium chromium, the many kinds. In order to standardize industry standards and make people have a rational and clear understanding of chromium alloys, the following are listed:
Standard high chromium alloy cast ball, cast grinding ball GB/T17445-2009 national standard:
Low chromium content chromium ball 1%-3%, hardness HRC≥45;
Multi-alloy ball 4%-6% chromium content of filter press pump, hardness HRC≥47;
7%-10% in chromium alloy ball, hardness HRC≥48 chromium content;
High chromium content chromium ball ≥10%-14%, hardness HRC≥58;


When the special high chromium content of the chromium ball exceeds 14%, the hardness HRC≥58.
The main components of the series of high chromium alloy filter feed pumps produced by our company adopt the special high chromium alloy cast ball filter press pump standard, and the hardness can reach 58HRC-62HRC. It is widely used for processing plants, coal washing, thermal power, and sand pumping. , Steel, smelting, chemical and other industries.
