Abstract

The invention relates to a light-weight fireproof castable for furnaces. The castable is prepared from the following raw materials in percentage by weight: 20-40% of volcanic rock, 15-35% of shale ceramsite, 15-35% of perlite, 5-15% of pure calcium aluminate cement, 0.1-1.5% of white clay and 1-3% of a bonding agent. The light-weight fireproof castable for the furnaces, disclosed by the invention, has the beneficial effects that volcanic rockwaste resources are mainly used as raw materials for making the light-weight fireproof castable, and besides, after the furnaces are disassembled, the light-weight fireproof castable can be recovered for reuse, and environmental protection is facilitated; the light-weight fireproof casting material has the advantages of being light in weight, good in thermal insulation performance, good in sound insulation performance, high in strength, convenient to construct, long in service life and the like, concurrently has the effects of load bearing, heat preservation and shock resistance, and can be widely used for working lining or permanent lining of middle and high temperature furnaces in electric power, chemical industry, metallurgy and the like.

Description

technical field [0001] The invention belongs to a novel light-weight refractory castable for the working lining or permanent lining of medium and high temperature furnaces such as furnace building and kiln building. Background technique [0002] Promoting and expanding the use of unshaped refractory materials is the development direction of furnace construction technology. In recent years, refractory plastics and refractory castables, which have been widely used in recent years, are the main unshaped refractory materials. Compared with refractory bricks, it saves molding, firing, etc. process, saving energy. The furnace is built with unshaped refractory materials, the overall performance of the furnace is good, it is tight, strong, and has a long life, thereby improving the operating rate of the furnace, so it can comprehensively improve the technical and economic indicators of the furnace. There is a castable that uses bauxite cement as a binder. Since the cement hydrate i...
