Abstract

A manufacturing process of refractory materials resistant to hydration from calcareous or dolomitic raw materials, characterized in that the crushed raw material is mixed with calcium chloride or lime chloride in an amount of 1 to 12% by weight, then the The mixture is briquetted or granulated and it is fried at temperatures of 800 to 1,600ºC, and after the obtained semi-product, the product molding paste is prepared after grinding by mixing this semi-product with a binder, which contains water or is anhydrous, or with an amount of calcium chloride or lime milk such that the total content of calcium chloride in the products relative to calcium oxide rises to 2-20% by weight, after which, from of the prepared paste, products are molded, which are applied in an uncooked form or cooked at temperatures of 800 to 1,300ºC or at a temperature of 1,300 to 1,750ºC.
