Casting workshops in many factories and mines in the country So far, the preliminary results on the reuse and utilization of steel scrap and inferior pig iron show that they have received some results to a certain extent and have played a certain role in overcoming the current tight supply of pig iron and scrap steel In order to promote and develop this work more effectively, I was commissioned by the editorial department to make a comprehensive introduction here only for the experiences and manuscripts and information reported by the factories (see the last reference).
