鉄水的加鎂方法直接影响球墨鑄鉄的质量、鎂的消耗和工人劳动条件。我厂参考国內外有关资料設計制造了一种新結构的密封处理包,經四年的生产实踐証明,操作簡便、安全可靠。如附图,密封包1(容量0.1～0.5吨)与盖3用鋼板焊接(經10公斤/厘米~2水压試驗)。处理时将包置于底座2上,倒入鉄水(液面比包边低50～100毫米)。在压紧圈14上放置白泥圈,然后将装有鎂錠的密封盖罩上,并在密封座9与塞10間放白泥,最后用螺杆5
The water plus magnesium method directly affects the quality of ductile cast iron, magnesium consumption and working conditions of workers. I plant reference to the relevant information at home and abroad to design and manufacture of a new structure of the seal treatment package, after four years of production proved that simple, safe and reliable. As shown in the attached drawings, the sealed package 1 (capacity of 0.1 to 0.5 ton) and the cover 3 are welded by steel plate (after 10 kg / cm ~ 2 hydrostatic test). The package will be placed on the base 2, into the water (liquid lower than the edging 50 ~ 100 mm). Placing a white mud ring on the pressing ring 14, then placing a sealing cap with a magnesium ingot, placing a white mud between the sealing seat 9 and the plug 10, and finally using a screw 5
