Abstract

The present invention relates to a kind of silica refractories, are made of the raw material of following parts by weight: 35-40 parts of basalt fibre, 59-80 parts of quartz sand, Al2O3 11-15 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, 15-22 parts of calcium oxide, 10-15 parts of boronation zirconium powder.Compared with existing part silica refractory, 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 silica refractory.

Description

Silica refractory
Technical field
The invention belongs to pipeline high temperature resistant technical fields, are related to a kind of silica refractory.
Background technique
Refractoriness is not less than 1599 DEG C of a kind of inorganic non-metallic material.Refractoriness refers to that silica refractory bullet tries Sample resists high temperature action without softening molten Celsius temperature in no loading.But it is only defined not with refractoriness Silica refractory can be described comprehensively, 1599 DEG C are not absolute.Now being defined as all physicochemical properties allows it in height The material used under warm environment is known as silica refractory.Silica refractory is widely used in metallurgy, chemical industry, petroleum, mechanical system It makes, the industrial circles such as silicate, power, dosage is maximum in metallurgical industry, accounts for the 69%~60% of total output.
Silica refractory is applied to steel, non-ferrous metal, glass, cement, ceramics, petrochemical industry, machinery, boiler, light industry, electricity The every field of the national economy such as power, military project is to guarantee that above-mentioned industry production run and technology develop essential basic material Material, plays irreplaceable important function in hot industry production development.
In the outer surface of green wood pipe material, one layer of silica refractory of setting is the usual way of this field pipeline, but by In technical restriction, this silica refractory intensity is not achieved standard in the art, service life be not it is very long, be difficult to reach Requirement to be achieved is needed to this field pipeline.
Summary of the invention
The purpose of the present invention is to provide a kind of intensity height, silica refractory with long service life.
The specific technical solution of the present invention is as follows:
A kind of silica refractory is made of the raw material of following parts by weight: 35-40 parts of basalt fibre, quartz sand 59-80 Part, Al2O3 11-15 parts, 2-4 parts of boric acid, 18-22 parts of zirconium oxide, 5-10 parts of magnesia, 10-15 parts of magnesium silicate, phenolic resin 1- 3 parts, 1-2 parts of silicon carbide, 15-22 parts of calcium oxide, 10-15 parts of boronation zirconium powder.
Preferably, the silica refractory is made of the raw material of following parts by weight: 37 parts of basalt fibre, quartz 70 parts of sand, Al2O3 13 parts, 3 parts of boric acid, 20 parts of zirconium oxide, 8 parts of magnesia, 12 parts of magnesium silicate, 2 parts of phenolic resin, silicon carbide 1.5 parts, 18 parts of calcium oxide, 12 parts of boronation zirconium powder.
Preferably, the Al2O3Granularity be 60-200 mesh, the granularity of the magnesia is 60-200 mesh.
Compared with existing part silica refractory, in process aspect, the present invention have simple process, cost is relatively low, The advantages of production energy-saving.In terms of technical indicator, intensity of the present invention with product is higher, improves the use of silica refractory Time can effectively improve its service life.
