水漂球式澆口是堵塞式澆口的一种,我們使用水漂球式澆口鑄造化学工业用的鑄鉄鍋、罐等鑄件,廢品率大大降低,避免了夾渣和砂眼等缺陷。水漂球式澆口構造如图1,水漂球是用耐火泥制成(耐火磚粉70％、耐火土20％、白泥10％),表面上涂以石墨粉经烘干后就可使用。 澆鑄时,鉄水澆入澆口杯,鉄水經过过道流入撇渣口,由于鉄水比重大于水漂球,所以当鉄水达到一定高度时,水漂球就被浮起(水漂球直徑为100公厘时,鉄水深
Float ball gate is a kind of plug gate, we use the water drift ball gate casting chemical industry cast pots, cans and other castings, greatly reducing the rejection rate, to avoid the slag and trachoma and other defects. Float ball gate structure shown in Figure 1, flooding ball is made of refractory mud (refractory brick powder 70%, refractory soil 20%, white mud 10%), the surface coated with graphite powder can be dried after use. Casting, pouring water into the sprue cup, swill water into the skimmer through the aisle, the swollen water proportion is greater than the flooding ball, so when the swollen water reaches a certain height, the flooding ball is floated (flooding ball Diameter of 100 mm, 鉄 deep water
