METHOD OF MANUFACTURING HYDRATION-RESISTANT REFRACTORIES FROM LIME AND DOLOMITE RAW MATERIALS.

摘要

We claim : 1. The method of manufacturing of hydration-resistant refractories from lime and dolomite raw materials, characterized in that the crushed raw material is mixed with calcium chloride or chlorinated lime in an amount of 1-12 per cents in weight, thereafter, the mixture is briquetted or granulated and calcined at a temperature of 800- 1600C, and from the obtained semi-finished product, after its crushing, a mass for moulding products is prepared by mixing it with the binding agent, either containing water, or anhydrous, or with such an amount of calcium chloride or lime milk as to make the total content of calcium chloride in relation to calcium oxide by 2-20 per cents in weight, whereafter, from the prepared mass products are moulded, which are used either in unburned state or they are burned at a temperature of 800-1300C. or at a temperature of 1300-1750C.
