Description

technical field

[0001] The invention relates to release powder, in particular to the application technology of a novel release powder in cylinder liner centrifugal casting. Background technique

[0002] At present, there are two main types of coatings, one is dry coatings mixed with quartz powder and binders (corn flour, potato flour, asphalt powder); the other is quartz powder plus bentonite, diatomaceous earth, laundry detergent, etc. A water-based paint that is mixed with powder, etc. and water.

[0003] The role of the coating is mainly to insulate the heat, prevent the molten iron from directly contacting the inner cavity of the mold, prevent the white structure caused by excessive supercooling, and smoothly push the casting out of the mold cavity.

[0004] The coating is applied in the mold cavity and between the molten iron of the cylinder liner. The performance of the coating has a great influence on the quality of the cylinder liner blank, machining allowance, exte...
