湖北省机械局受机械工业部的委托于82年7月7日～9日在武汉召开了“提高陶瓷型精铸锻模精度、表面光洁度和寿命的研究”鉴定会。到会的有有关领导机关、科研单位、大专院校、工厂等29个单位的46名代表。 会议分别听取了武汉机械工艺研究所,武汉精密铸造厂,长春第一汽车制造厂的研制报告,参观了武汉精密铸造厂、武汉汽车修配厂。代表们认为: 1.陶瓷型精铸工艺选择热稳定性良好的耐火材料和恰当的粒度比,其锻模表面光洁度一般可达5,经过抛磨,可满足锻模生产的要求。 2.简单型腔的精铸锻模,其型腔单面的抛磨
Hubei Provincial Bureau of Machinery Industry by the Ministry of Machinery Industry commissioned on July 7, 1982 ~ 9 held in Wuhan, “to improve the accuracy of ceramic casting forging precision, surface finish and life of the” identification will. At the meeting, there were 46 representatives of 29 units including relevant leading organs, research institutes, tertiary institutions and factories. The meeting respectively listened to the research reports of Wuhan Mechanical Technology Institute, Wuhan Precision Casting Factory and Changchun No.1 Automobile Factory, and visited Wuhan Precision Casting Factory and Wuhan Automobile Repair Factory. The deputies said: 1. Ceramic casting process Select a good thermal stability of refractory materials and the appropriate particle size ratio, the forging die surface finish generally up to 5, after polishing, die forging production to meet the requirements. 2. Simple cavity casting die forging, polishing its single-sided cavity
