高韧性球铁在退火过程中的温度控制对于降低铸件的废品率和燃料消耗十分重要,我们对此进行了革新,在烧煤退火窑上装了一台自动控制装置,使退火温度实现了自动控制,于1978年9月投入生产。经验证,性能良好,运转正常可靠,退火后的球铁机械性能比过去显著提高。每一退火炉次节约煤150公斤左右。现将此装置的工作原理、技术参数、控制系统简介如下:
The temperature control of high ductile ductile iron during annealing is very important for reducing the rejection rate and fuel consumption of castings. We have innovated this and installed an automatic control device on the coal-fired annealing kiln to realize the automatic control of the annealing temperature , In 1978 September put into production. Proven, good performance, normal and reliable operation, the ductile iron after annealing mechanical properties significantly improved over the past. Each annealing furnace saves about 150 kilograms of coal. Now this device working principle, technical parameters, control system is as follows:
