Technology for producing perforated plate spare components such as pouring basket lid etc. using waste molten steel

The present invention discloses a casting process for producing pouring basket cover by using waste molten steel in steel works. Said casting process includes mold-making, mold-stoving and casting procedures. Its mold-making procedure is as follows: using sheet steel to make frame according to the external form of pouring basket; building up firebricks into heat-insulating layer along the internal side of the frame; finally, leveling by applying refractory clay, and for its upper U-shaped ring hole, a U-shaped mold with heat-insulating layer is made up. It features simple technological process, convenient mold-stoving procedure and low cost, etc..
