Product description
The hot rolled steel ball is the steel ball formed by hot rolling round steel with the hot extrusion times of above 10 times produced by large steel works, which is controlled automatically in the whole process with uniform steel ball hardness, higher core hardness, low crashed rate and big impact value of steel ball. The performance of steel ball has difference according to different material of raw materials adopted. The hot rolled steel ball is produced with the production line of skew rolling, of which not only the production efficiency is high but also the wear resistance increases successively and quality is stable due to the rapid rise of introduction of new materials and new technologies in recent years.
1. Hot rolled ball is to make steel ball cool rapidly with unique quenching process to urge austenite in metal structure to turn into martensite structure with relative wearable hardness, so the hardness is generated by quenching process.
2. Because theround steel molded by producing with square billet by hot extrusion is used as the production raw material of hot rolled ball and the hot rolled ball needs to be molded by roll extrusion in the production process at the same time, so the density is generally more than 7.85 or above.
3. Because the finished round steel is adopted to hot rolled ball, the quality is uniform, mechanized assembly line work mode is realized in the whole production process from induction heater with round steel, rolling mill, quenching machine, cooling ball platform to package, same temperature, speed and other technological parameters is traced and controlled by computer so as to ensure stable and uniform production quality.
4. The crashed rate of hot rolled ball is quite low because the density is high, impact toughness is more than or equal to 12 (J/cm2) and fatigue life is more than or equal to 1000 times in falling ball test at the height of 6m.
