Problems solved by technology

Existing refractory products mainly include magnesia-chrome bricks, magnesia-aluminum spinel bricks, etc. When used in converters, ladles, cement kilns, and electric furnace linings, due to problems such as large ladles and cement kilns, high temperatures, and harsh service conditions, etc. Some products have the disadvantage of short service life, which increases the frequency of repairing lining and kiln lining and reduces production efficiency. Secondly, the use of chromium products causes environmental pollution, and the original magnesia-aluminum spinel is limited by new technologies, so special research and development Indicator’s Spinel Products Are Imminent

Abstract

The invention discloses an iron-aluminum-magnesium oxide synthetic material product and a manufacturing method thereof, and relates to an inorganic non-metallic material. The preparation method comprises the following steps: firstly, mixing electrically fused iron-aluminum-magnesium oxide synthetic materials with different particle sizes, then adding hematite and calcium oxide clinker, mixing andball-milling to prepare mixed powder, then mixing dextrin powder with water, adding chitosan, potassium nitrate and a butyl titanate alcohol solution, stirring and mixing to obtain mixed dextrin liquid, mixing the mixed powder with the mixed dextrin liquid to obtain mixed slurry, stirring the mixed slurry, ageing, molding, drying again, and firing to obtain the iron-aluminum-magnesium oxide synthetic material product. The iron-aluminum-magnesium oxide synthetic material product prepared by the method has excellent fire resistance and alkali resistance.

Description

Technical field[0001]The invention provides an iron-aluminum-magnesium oxide synthetic material product and a manufacturing method thereof, and relates to the technical field of inorganic non-metallic materials.Background technique[0002]At present, industries such as iron and steel and cement kilns urgently need an excellent functional product that is resistant to high temperature, thermal shock, peeling, and easy to hang ladle lining or kiln skin. The current refractory products mainly include magnesia-chrome bricks, magnesia-aluminum spinel bricks, etc., which are used in converters, ladles, cement kilns, and electric furnace linings. Due to the large capacity, high temperature and harsh use conditions of the ladle and cement kiln, problems such as Some products have the shortcoming of short service life, which increases the frequency of repairing package lining and kiln lining, and reduces production efficiency. Secondly, the use of chromium products has environmental pollution, ...
