Embodiment Construction

[0006] Before preparing the castable, the raw materials of volcanic rock, shale ceramsite, and perlite are first crushed so that the particle size does not exceed 1 mm. The volcanic rock can also be used as waste, aluminate cement can be used as a binder, and the admixture soluble in water can be used Alkali, such as sodium bicarbonate, etc., the amount of admixture alkali is no more than 0.2% of the total weight of the above raw materials.

[0007] Example 1. Get 100 kg of crushed raw volcanic rock, 20 kg of shale ceramsite, 10 kg of perlite, 20 kg of aluminate cement, and 0.2 kg of admixture. The above raw materials are evenly mixed and packed into bags for use.

[0008] Example 2: Get 100 kg of crushed raw volcanic rock, 30 kg of shale ceramsite, 15 kg of perlite, 30 kg of aluminate cement, and 0.2 kg of admixture, mix the above raw materials evenly, and put them in bags for use.

[0009] Example 3: Get 100 kg of crushed raw volcanic rock, 40 kg of shale ceramsite, 20 kg of...

Abstract

An environment friendly light sound-proof refractory casting material belongs to the light sound-proof refractory casting material used for a working lining or a permanent lining of medium-high temperature furnaces such as a building furnace, a building kiln, and the like. The main raw materials for manufacturing the casting material comprise volcanic, shale particles, powder pearl and aluminate cement, the weight ratio among which is 100:20-40:10-20:20-40; and the main raw materials are uniformly blended to form the casting material. The material has the beneficial effects that the environment friendly light sound-proof refractory casting material mainly uses volcanic rock abandon resources as raw materials, can be recycled after the furnace is dismantled, is beneficial to environmental protection, has the advantages of light weight, heat insulation, sound-proof, high strength, convenient construction, long service life and the like, simultaneously has the function of load-bearing, heat preservation and anti-seismic, and can be widely applied to the working lining or the permanent lining of the medium-high temperature furnaces of electricity, chemical industries, metallurgy, etc.

Description

1. 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. 2. Background technology [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 kind of castable that uses bauxite cement as the binder. Since the...
