Abstract

The invention discloses a casting coating produced from a steelmaking runner waste material and a preparation method thereof. The casting coating is prepared from the following raw materials: 80-100 parts of steelmaking runner waste material powder, 0-15 parts of graphite powder, 10-50 parts of bauxite powder, 10-50 parts of mullite powder, 6-8 parts of resin, 6-8 parts of a suspending agent and an appropriate amount of a solvent. The preparation method comprises the following steps of adding the suspending agent, resin and the appropriate amount of solvent into a stirrer, stirring for 10-30 minutes, adding the steelmaking runner waste material powder, the graphite powder, the bauxite powder and the mullite powder, stirring for 30-60 minutes and adding the appropriate amount of solvent until an appropriate specific weight is adjusted, so as to obtain the casting coating. Since the steelmaking runner waste material is adopted as the raw material, the production cost is low, not only is the difficult problem of the discharge of the waste solved, but also the suspension and application properties of the coating are improved, the comprehensive utilization of the produced steelmaking runner waste material is achieved and thus the casting coating has very strong market competitiveness and popularization and application values.

Description

technical field [0001] The invention relates to the field of casting coatings, in particular to a casting coating produced by using steelmaking sprue waste and a preparation method thereof. Background technique [0002] Foundry coatings refer to casting auxiliary materials that are used to coat the surface of the cavity or sand core to change their surface refractoriness, chemical stability, metal erosion resistance, sand sticking resistance, etc. It is composed of various properties The dispersion system composed of different materials mainly includes refractory materials, suspending agents, carriers, binders and special additives. When acting on castings, it is required that the coating has good process performance, work performance, quality stability and application reproducibility. Prevent defects such as cracking, trachoma, and white iron formation caused by excessive local cooling of casting products. There are many kinds of casting coatings, which can be roughly div...
