Silicon amorphous refractory hot patching material

Abstract

The invention relates to a silicon amorphous refractory hot patching material. The silicon amorphous refractory hot patching material is prepared by mixing fused quartz particles with silica sol liquid, wherein the fused quartz particles contains the following components in percentage by weight: 4%-6% of fused quartz sand with a particle size of 0.2mm-0.3mm, 18%-22% of fused quartz powder with theparticle size of 0.065mm-0.075mm and 72%-78% of fused quartz powder with the particle size of 0.035mm-0.04mm. Damaged parts with all kinds of shapes and specification of a kiln and fused parts in allsizes can be patched by virtue of the silicon amorphous refractory hot patching material from, and the damaged parts and the fused parts are firm and compact after being patched.

Description

technical field [0001] The invention relates to a silicon amorphous refractory hot-filling material, which is applied to the maintenance of the interior of a high-temperature kiln and the melted part of a silica brick refractory material. Background technique [0002] At present, in the production process of high-temperature kilns built with refractory bricks, silicon refractory bricks are widely used due to their economical applicability. [0003] Many parts of the high-temperature kiln are made of silica bricks, and in high-temperature production, the refractory bricks inside the kiln are due to various reasons during the production process of the kiln (such as misuse of the kiln by the operator of the company, kiln Due to the erosion and erosion of the burning flame in the furnace, the sudden cooling and rapid heating of the internal temperature of the kiln after the cessation of fire and cooling, the rapid cooling and rapid heating of the internal temperature, and the er...

Problems solved by technology

[0003] Many parts of the high-temperature kiln are made of silica bricks, and in high-temperature production, the refractory bricks inside the kiln are due to various reasons during the production process of the kiln (such as misuse of the kiln by the operator of the company, kiln Due to the erosion and erosion of the burning flame in the furnace, the sudden cooling and rapid heating of the internal temperature of the kiln after the cessation of fire and cooling, the rapid cooling and rapid heating of the internal temperature, and the erosion of the internal acid-base gas formed in the raw material process of the production of products, etc., the refractory bricks built by the kiln will all appear. Different degrees of melting loss, bursting defects, etc.), the damage of refractory bricks inside the kiln gradually evolves, which will affect the overall service life of the kiln in the later stage

[0004] After the above conditions occur, the refractory bricks inside the kiln will burst into flames after being damaged. After this phenomenon occurs, the internal temperature of the kiln will radiate to the outside, which will not only cause the loss of burning heat of the kiln, but also affect the external operation of the kiln. The working environment of personnel has also become worse. More importantly, the fire on the outer wall of the kiln will cause safety hazards to the steel structure, columns and other supports outside the kiln.

If left untreated it will burn out the external steel structure
