我厂产品铜瓦铜套较多,且规格较大,一般直径在400毫米左右,毛坯重影一般在100至300公斤,过去一直采用砂型铸造,废品率高达T0~80拓,铜料消耗太大,影响加工进度。现在我俩制造成功一台大型离心浇铸机,使用效果很好,废品率下降到5多,8扇铜瓦过去用料1 200公斤,现只要840公斤,省铜料达360公斤, I copper copper plant more products, and larger specifications, the general diameter of about 400 mm, ghosting generally 100 to 300 kg, the sand casting has been used in the past, the rejection rate as high as T0 ~ 80 Extension, copper consumption too Large, affecting the processing progress. Now that we have successfully manufactured a large centrifugal casting machine, the effect is very good. The reject rate has dropped to more than 5, with the output of 8 copper tiles being 1,200 kilograms in the past, now it is 840 kilograms, and the provincial copper material reaches 360 kilograms.
