随着我国社会主义建设事业的发展,很多部门对阀门的产量和质量提出了越来越高的要求,特别是近年来石油生产大幅度增长和原油出口援外任务的逐年增加,迫切要求阀门生产厂生产更多、更好的阀门。我厂按行业对产品分工布点的要求,需要将锻钢截止阀的产量和质量翻上去。但根据我厂的现实情况,困难较大,尤其是存在着冷热加工能力不相适应的矛盾,即热加工毛坯生产跟不上冷加工的产量。对于锻钢截止阀的生产,迫切需求采用新工艺,提高它的产量和
With the development of China’s socialist construction, many departments put forward higher and higher requirements on the output and quality of valves. In particular, the substantial increase of oil production and the increasing number of tasks of foreign aid for export of crude oil have been increasing year by year, urging the valve manufacturing plant Produce more and better valves. I plant the distribution of products by industry requirements of the distribution needs of the steel forgings valve output and quality turned up. However, according to the actual situation in our factory, the difficulties are great. In particular, there is a contradiction between incompatible hot and cold processing capabilities, that is, the production of roughing blanks can not keep up with the output of cold working. For the production of forged steel globe valves, there is an urgent need to adopt new processes to increase its production and output
