Ball mill grinding steel rolling ball
Our hot rolling steel ball size from 20mm to 80mm, have precise size, round geometry, high hardness and good mechanical properties, and have excellent quality of wear resistance, no deformation and low cracking. Its characteristics are as follows:
1. High overall hardness: the surface hardness can reach 60-65hrc, the volume hardness can reach 60-65hrc, and the hardness gradient distribution is uniform.
2. High impact toughness: the impact toughness is greater than 12j / cm2;
3. The actual breaking rate is not more than 1%.
We produce hot rolling steel balls with very strict quality control system. An independent laboratory, the advanced and accurate lab equipment, to ensure that each step of the production process is performed in accordance with the quality standards.
our company have also been verified with ISO9001 Quality Certification, ISO45001 Occupational health and safety certification and ISO14001 environmental management system certification.
