Abstract
The invention relates to a refractory coating composition for producing mold coatings on non-permanent molds or on cores for the casting of iron and steel, comprising a) an alkali metal salt or alkaline earth metal salt of carbonic acid and/or an alkali metal salt or alkaline earth metal salt of diphosphoric acid, b) a carrier liquid and c) refractory materials.
Claims18
A refractory coating composition for producing mold coatings on non-permanent molds or on cores for the casting of iron and steel, comprising
- a) 0.5 to 30% by weight of an alkali metal salt or alkaline earth metal salt of diphosphoric acid, based on the total weight of the refractory coating composition and 0.5 to 30% by weight of an alkali metal salt or alkaline earth metal salt of carbonic acid, based on the total weight of the refractory coating composition, or
- 0.5 to 30% by weight of an alkali metal salt or alkaline earth metal salt of hydrogencarbonate, based on the total weight of the refractory coating composition, or
- 0.5 to 30% by weight of an alkali metal salt or alkaline earth metal salt of dihydrogendiphosphate, based on the total weight of the refractory coating composition,
- b) a carrier liquid and
- c) refractory materials,
- wherein the solids content of the refractory coating composition is from 10 to 85% by weight.
