Technical Key Points

Ø 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.

Ø Control the usage rate of recycled material. When melted in the atmosphere, most of the easily oxidized elements in the material are present in the form of inclusions. Therefore, the amount of inclusions to be taken into account and the usage of recycled material must be controlled. for the stainless steel guide vane, the provisions of the return material amount should be not more than 15%.
