本厂有色金属铸件生产采油柴油坩埚炉,平均熔化200公斤ZQSn10-2铜合金约需77分钟,耗油达75公升/罐。熔化时间长,耗油多,合金液容易吸气,经济效益也比较低。为此,我们努力寻求提高熔化速度的方法。根据熔化过程中炉内有时冒出青烟,及拆卸喷头时在本体内积存较厚的油垢这些现象,我们判断炉内油的燃烧不够充分,导致炉子热效率低,因此我们从喷嘴结构上 Our non-ferrous metal casting production diesel oil crucible furnace, the average melting of 200 kg ZQSn10-2 copper alloy takes about 77 minutes, fuel consumption of 75 liters / tank. Long melting time, fuel consumption, easy to get suction liquid alloy, the economic benefits are relatively low. To this end, we strive to find ways to increase the rate of melting. According to the phenomena of sometimes smoke inside the furnace during the melting process and the thick greasy dirt accumulated in the body when the discharge head is removed, we judge that the furnace oil is not sufficiently burned, resulting in low thermal efficiency of the furnace. Therefore,
