Important aspects of cast iron quality management

Based on the problem-solving methodology, which is a detailed version of Deming›s Plan-Do-Check-Act (PDCA) improvement cycle, an innovative production facility for the remelting of fine metal-containing waste using an efficient, resource-saving technology has been created. In the developed furnace for electroslag remelting with graphite electrodes, the loss of metal for waste was 2%. The technology of electroslag remelting is distinguished by the presence of a layer of highly superheated slag, which protects the melt from oxidation. At the same time, significant savings in raw materials, energy and labor resources have been achieved. At the same time, a significant increase in resource-saving and environmental indicators of the quality of cast iron is ensured, while maintaining the functional indicators of castings at a given level.
