Problems solved by technology

When used, it is generally a double-layer lining structure, a layer of light castable and a layer of high-temperature resistant heavy castable. This double-layer lining structure not only increases the thickness of the inner lining, but also brings load to the device, and the construction is troublesome. In particular, a weak layer is easily formed between the double-layer lining due to the difference in material, which in turn causes separation and damage between the two layers; the construction method is vibration and smearing, and the construction strength is high; in order to meet the requirements of use, single-layer lining has become a development trend

Embodiment Construction

[0008] A light-weight high-strength self-flowing castable manufacturing process, the proportioning is as follows according to the mass ratio: 60 parts of mullite light aggregate, 10 parts of bauxite clinker powder, 6 parts of mullite powder, 9 parts of silicon micropowder, and alumina micropowder 5 parts, 10 parts of calcium aluminate cement, 0.5 parts of additives; bauxite clinker powder is 200 mesh; particle size of alumina micropowder is 3μm-5μm; raw materials are purchased according to the formula; The mullite light aggregate is crushed, and then screened by an electromagnetic vibrating screen. The particle size of the mullite light aggregate is divided into 5mm-3mm, 3mm-1mm, and 1mm-0mm. Grind into 200-mesh fine powder; based on the principle of mixing 1 ton in a single batch, weigh all the raw materials according to the ratio; first mix mullite light aggregate, bauxite clinker powder, mullite powder, silica powder, Put the aluminum micropowder into a strong mixer and mix...

Abstract

The invention provides a manufacturing process of a light-weight and high-strength self-flow castable. The light-weight and high-strength self-flow castable comprises the following raw materials in parts by weight: 60 parts of mullite lightweight aggregate, 10 parts of alumina clinker powder, 6 parts of mullite powder, 9 parts of silica powder, 5 parts of alumina micro-powder, 10 parts of calcium aluminate cement and 0.5 part of additives, wherein the particle size of the alumina clinker powder is 200 meshes; the particle size of the alumina micro-powder is 3-5 microns. The manufacturing process of the light-weight and high-strength self-flow castable provided by the invention has many excellent performances such as light weight, high strength and heat isolation, is suitable for the working linings and composite linings of industrial furnaces, and especially suitable for places with complex shapes and quite small construction thicknesses.

Description

technical field [0001] The invention relates to a manufacturing process of a light-weight and high-strength self-flowing castable, which belongs to the technical field of cement. Background technique [0002] Traditional lightweight castables are only used for thermal insulation linings due to the contradiction between thermal insulation, strength and high temperature resistance. When used, it is generally a double-layer lining structure, a layer of light castable and a layer of high-temperature resistant heavy castable. This double-layer lining structure not only increases the thickness of the inner lining, but also brings load to the device, and the construction is troublesome. In particular, a weak layer is easily formed between the double-layer linings due to the difference in materials, thereby causing separation and damage between the two layers; the construction method is vibration and smearing, and the construction strength is high; in order to meet the requirements ...
