Technical key points

u  Take effective measures to reduce the casting temperature to eliminate crack defects, at the same time reducing the temperature drop of molten steel to ensure the filling capacity of steel. Main technical measures: one is to directly reduce the casting temperature, the original pouring temperature of 1600 ℃ -1610 ℃, and now strictly control the temperature at 1570℃ -1580 ℃. Second, to reduce the temperature drop of molten steel. After the mold are assembled, blow heat wind 150 ℃ -200 ℃ to the cavities for 60 min-90min, and stop blowing 5min before pouring.

u  Pouring should be fast, first calculate the pouring time, apply plunger type leakage bag to pour in stipulated time.
