Abstract

The present invention relates to a kind of refractory materials, are made of the raw material of following parts by weight: 59-80 parts of quartz sand, Al2O310-13 parts, 2-4 parts of boric acid, 18-22 parts of zirconium oxide, 5-10 parts of magnesia, 10-15 parts of magnesium silicate, 1-3 parts of phenolic resin, 1-2 parts of silicon carbide.Compared with existing part refractory material, in process aspect, the present invention has the advantages that simple process, cost is relatively low, production energy-saving.In terms of technical indicator, intensity of the present invention with product is higher, improves using the time, can effectively improving its service life for refractory material.

Description

Refractory material
Technical field
The invention belongs to pipeline high temperature resistant technical fields, are related to a kind of refractory material.
Background technique
Refractoriness is not less than 1599 DEG C of a kind of inorganic non-metallic material.Refractoriness refers to that refractory material bullet sample exists In the case of not having loading, high temperature action is resisted without softening molten Celsius temperature.But it only cannot be complete to define with refractoriness Face describes refractory material, and 1599 DEG C are not absolute.Now being defined as all physicochemical properties allows it under high temperature environment The material used is known as refractory material.Refractory material is widely used in metallurgy, chemical industry, petroleum, machine-building, silicate, power etc. Industrial circle, dosage is maximum in metallurgical industry, accounts for the 69%~60% of total output.
Application to refractory in steel, non-ferrous metal, glass, cement, ceramics, petrochemical industry, machinery, boiler, light industry, electric power, The every field of the national economy such as military project is to guarantee that above-mentioned industry production run and technology develop essential basic material, Irreplaceable important function is played in hot industry production development.
In the outer surface of green wood pipe material, the usual way that one layer of refractory material is this field pipeline is set, but due to skill Art limitation, this refractory material intensity is not achieved standard in the art, service life be not it is very long, be extremely difficult to this field Pipeline needs requirement to be achieved.
Summary of the invention
The purpose of the present invention is to provide a kind of intensity height, refractory material with long service life.
The specific technical solution of the present invention is as follows:
A kind of refractory material is made of the raw material of following parts by weight: 59-80 parts of quartz sand, Al2O310-13 parts, boric acid 2-4 Part, 18-22 parts of zirconium oxide, 5-10 parts of magnesia, 10-15 parts of magnesium silicate, 1-3 parts of phenolic resin, 1-2 parts of silicon carbide.
Preferably, the refractory material is made of the raw material of following parts by weight: 70 parts of quartz sand, Al2O312 parts, boron Sour 3 parts, 20 parts of zirconium oxide, 7 parts of magnesia, 12 parts of magnesium silicate, 2 parts of phenolic resin, 2 parts of silicon carbide.
Preferably, the Al2O3Granularity be 60-200 mesh, the granularity of the magnesia is 60-200 mesh.
Compared with existing part refractory material, in process aspect, the present invention has that simple process, cost is relatively low, energy conservation The advantages of production.In terms of technical indicator, the present invention have product intensity it is higher, improve refractory material using the time, can To effectively improve its service life.
Specific embodiment
The present invention is further illustrated below in conjunction with specific embodiment.
