| Abstract: | It is proven that the captioned coating material coded as "Luo 90-1" is convenient to use, high in heat conductivity, resistant to high temperature oxidation, penetrable by air, strongly cohesive after applied onto the mold and good in lubricating properties and can achieve bright coated surface. It will not hinder the flow of the liquid metal, nor will not need special tools for cleaning up the remaining sand. By using this kind of coating material, the quality of the surface and the subsurface layer of copper and its alloy castings is improved and the original quality index 75% is raised by 20%. |
