我公司在生产AZ31B镁合金200 mm×800 mm扁锭的工艺过程中,将浇铸管在原有长度3 700 mm上加长了500 mm成为4 200 mm,直径由原来的33 mm改为25 mm,斜度由原来的12°改为20°,石棉布包裹厚度由原来的10 mm改为2 mm。以上改动使扁锭的生产成品率提高了很多。浇铸管加长后使镁合金液在浇铸
In the process of producing AZ31B magnesium alloy 200 mm × 800 mm slab, our company lengthened the length of the casting pipe from 500 mm to 4 200 mm on the original length of 3 700 mm and changed the diameter from 33 mm to 25 mm Degree from the original 12 ° to 20 °, asbestos package thickness from the original 10 mm to 2 mm. The above changes have greatly increased the production yield of slab. After the casting pipe is lengthened, the magnesium alloy liquid is cast
