Description

technical field [0001] The invention belongs to the field of lost foam casting coatings, in particular to a vanadium iron slag-high alumina blast furnace slag lost foam casting coating and a preparation method thereof. Background technique [0002] Lost foam casting technology is a new casting process in the foundry industry. The lost foam casting process refers to making foam plastic (EPS, ETMMA or EPMMA) into the shape, structure and size of the required castings. After the refractory coating is dried, it is embedded in a special sand box with dry sand (usually quartz sand) for molding, and then poured under a certain negative pressure. Lost foam casting is mainly called dry sand solid mold casting and negative pressure solid mold casting in China, and it is referred to as EPC casting abroad. [0003] At present, the most mature lost foam casting process is used in the mass production of automotive castings. The products produced include aluminum alloy castings (such as i...
