Refractory material

Abstract

The invention discloses a refractory material which is characterized by comprising the following components in parts by weight: 10-15 parts of ceramic particles, 15-25 parts of crushed stones, 2-4 parts of fly ash, 0.02-0.04 part of hydroxyethylcellulose, 0.5-0.8 part of citric acid, 0.1-0.5 part of sodium carbonate, 5-12 parts of alumina, 0.2-1 part of a dispersant and 5-20 parts of water. According to the invention, coal resources can be reasonably developed, industrial solid wastes such as the fly ash and the like can be massively utilized, and comprehensive utilization of resources and environmental friendliness are facilitated; the product of the refractory material can simultaneously meet the requirements of national standards on initial setting time, final setting time, strength andthe like; and the product of the refractory material has sufficient wear resistance, good volume stability, good chemical stability and long service life.

Description

technical field [0001] The invention belongs to the field of building materials, and more specifically relates to a refractory material. Background technique [0002] A class of inorganic non-metallic materials with a refractoriness not lower than 1580°C. Refractoriness refers to the Celsius temperature at which a refractory conical sample can resist high temperature without softening and melting without load. However, it is not possible to fully describe refractory materials only by the definition of refractoriness, and 1580°C is not absolute. It is now defined as a material whose physical and chemical properties allow it to be used in a high temperature environment is called a refractory material. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields, and are used in the largest amount in the metallurgical industry, accounting for 50% to 60% of the total output.

AI Technical Summary

Problems solved by technology

[0004] However, due to disorderly mining, low level of processing technology, low level of comprehensive utilization of resources, and serious waste, the above-mentioned mineral resources, especially high-grade refractory raw material resources, have become less and less. Saving resources and comprehensively utilizing resources has become a top priority.

[0005] The existing technology lacks a kind of refractory coal that can reasonably develop coal resources, meet the requirements of the national standard for initial setting time, final setting time, strength, etc., has sufficient wear resistance, good volume stability, good chemical stability, and long service life.
