8×2.5米燃油时效炉,是我厂铸造车间一九七二年九月开始设计施工的技术改造项目,一九七三年四月底建成,同年六月底正式交付生产。8×2.5米燃油时效炉的建成,大大减轻了工人的笨重体力劳动,改善了劳动条件,解决了由于煤气燃料不足给生产带来的严重影响,特别是由于炉体结构的改革,热源的合理布置,以及采取了控制炉温的有效措施,使温差由原来的±100℃下降到±10℃左右,这就大大提高了时效质量,从而保证了铸件几何精度的稳定性。
8 × 2.5m oil aging furnace, is our factory foundry workshop in September 1972 began the design and construction of technological transformation projects, completed in April 1973 by the end of April, the same year the official delivery of production. The construction of the 8 × 2.5m oil-fired furnace has greatly reduced the heavy labor of workers, improved the working conditions, and solved the serious impact on the production due to the shortage of gas fuel. In particular, due to the reform of the furnace structure, the heat source is reasonable Layout, and take effective measures to control the furnace temperature, the temperature difference from ± 100 ℃ down to about ± 10 ℃, which greatly improves the aging quality, thus ensuring the stability of the casting geometry accuracy.
