An annual output of more than 700,000 Kg of steel heat treatment plant design miniature bearings
Abstract: This design is the heat content of the workshop and rational design, through to the Tian An Bearing Co., heat treatment workshop practice, according to the production task and the next on-site field observations typical production process and equipment operation; develop a reasonable job system and the heat treatment process, select the appropriate device, arranged for staff to arrange and computing workshop layout, production costs.We hope that this design can be somewhat more reasonable designs and ideas are accepted and concerns, and applied to actual production. Rational use of resources of the enterprise, in order to constantly improve the quality of heat treatment of miniature bearings, production and technical and economic indicators improved floor space utilization, reduce production costs and environmental pollution and make a little contribution. Can also promote the development
of related industries together to improve the overall level of China's industry.
