北京重型机械厂锻压车间2×4.64台车式加热炉原来采用高压喷射式烧嘴,由于炉底尺寸设计不当,烧嘴能量偏小,管道及烧嘴被煤气含尘物(焦油、灰)堵塞,炉子加热性能不好,长期达不到正常炉温,一般只能作锻件保温式锻后热处理加热使用。当车间生产任务增加时,便显出炉子加热能力不能满足使用要求,并与水压机锻造能力不相适应。为了解决这一问题,一机部设计研究总院设计处与厂方共同协议将该炉子加以改造。一、改造方案和预期达到的效果 (一)采用煤气平焰烧嘴改造加热炉由于是初次将煤气平焰烧嘴使用于台车式加热炉,国内又无这方面的实践经验,因此,在制定方
Beijing Heavy Machinery Factory forging workshop 2 × 4.64 trolley furnace used high-pressure jet burner, due to improper design of the bottom of the furnace size, burner energy is too small, pipes and burners were gas dust (tar, ash) plug , Furnace heating performance is not good, long-term reach the normal furnace temperature, generally only forgings forging heat treatment forging heat. When the workshop production tasks increase, it shows that the furnace heating capacity can not meet the requirements, and not suitable for hydraulic press forging capacity. In order to solve this problem, a machine design institute of Design Institute and the factory jointly agreed to transform the stove. First, the transformation program and the expected results (a) the use of gas flame burner to transform furnace Since it is the first time the flat gas burner used in car-type furnace, the country has no practical experience in this regard, therefore, at Formulate
