Mining machinery is a kind of machinery that processes ores and makes low-quality ores useful.
The bearing steel used in mining machinery is used in a very harsh environment. Bearings are prone to cracking and peeling on the contact surface under the action of periodic load, which greatly reduces its service life. In order to ensure the service life of the product, it is necessary to have high and uniform hardness, wear resistance and high elastic limit. The requirements for the uniformity of the chemical composition, the content and distribution of non-metallic inclusions, and the distribution of carbides against the bearing steel are all very strict. Hongsheng has the production capacity to provide electroslag cold work die steel round blanks with diameters below Φ500mm.
Focus on manufacturing special steel cast and forged
components for more than 25 years.
