product description

Various roller shaft components such as rolling rolls, conveying rolls, supporting rolls, vertical rolls, guide rolls, and sinking and floating rolls on the steel rolling production line are made of different materials such as forged alloy steel, cast alloy steel, alloy cast iron, ductile iron, etc. All types of rolling mill components are used under conditions of high temperature, high variable load, alternating cold and heat, corrosion, wear, and fatigue.
According to preliminary statistics, the annual consumption of various rolling mills by steel enterprises in China is about 8-10 billion yuan. The surface strengthening treatment was carried out using laser nano ceramic alloying and laser composite strengthening technology, which improved the strength, hardness, wear resistance, thermal stability, red hardness, corrosion resistance, fatigue resistance and other performance indicators of the surface, effectively increasing the steel passing capacity of the rolling mill. After being applied by multiple steel companies, the service life of various types of rollers such as rolling mills can generally be increased by 50% to several times.
