Riser covering agent is also called heat preservation agent, dedicated to common Ming riser steel casting sand mold, in the case of without heat insulating riser set, also can make the absorption of riser pipe shrinkage by "V" for "U" shape deformation, avoid the osteoporosis and the shrinkage cavity, was 30%, and the effect on riser weight reduced by 50% - 75%, yield increased by more than 15%, and guarantee the chemical composition of casting, each save a ton of steel only $7-9, and carbonized rice husk, fever, plant ash and heat insulating riser set product compared to a significant social and economic benefits.
Features: 1. Good feeding performance can reduce riser volume during casting, save molten steel, ensure the compact structure of the casting and no shrinkage hole and loose, and maximize the product yield. 2. Good spreading property, can be evenly spread on the surface of molten steel, can bond the molten slag and impurities on the surface of molten steel together, play a good slag accumulation effect, and easy to remove. 3. The formation of a stable and reasonable heating layer, slag liquid layer, thermal insulation layer, can effectively prevent the surface of molten steel heat radiation, heat conduction, heat convection, has a good thermal insulation effect. 4.Low carbon content, can completely avoid the casting of carbon ( type).
