Description
Technical Field
The invention relates to the technical field of casting coating production, in particular to a light-color casting coating for cast iron prepared from polishing waste residues and a preparation method thereof.
Background
Casting is the basis of equipment manufacturing development, the demand of high-quality iron castings gradually increases day by day, the quality of a working surface of a sand mold (core) in direct contact with molten metal has very important influence on the quality of the castings in the casting production process, and coating the working surface of the sand mold (core) is an economical, practical and effective method for improving the quality of the castings. At present, the cast iron coating generally takes microcrystalline graphite powder and crystalline graphite powder as basic refractory materials, and is a typical pure refractory coating. The graphite powder has high refractoriness and low price, is not wetted with iron alloy and other metals, can separate out bright carbon at the casting temperature, and generates reducing atmosphere at a mould (core) interface, thereby forming a layer of protective film on the surface of the coating, further reducing the wetting capacity of molten iron to a casting mould, and obtaining the iron casting without sand sticking as long as the coating is uniform and has enough strength. However, the black graphite powder coating has the defects of severe working environment, easy coating leakage, easy occurrence of burrs, sand sticking and the like at the hot spot of a thick and large casting and the part flushed by molten metal during preparation and use. The problem that a layer of black ash which is not easy to remove is left on the surface of the casting after the sand falling. Although the light white zircon powder coating and the zirconia corundum coating can comprehensively solve the problems, the cost is too high, and the large-area popularization is difficult.
