Embodiment Construction

[0006] A low-cement bonded castable, the proportioning is as follows according to the mass ratio: 60 parts of bauxite aggregate, 15 parts of bauxite clinker powder, 9 parts of silica micropowder, 6 parts of alumina micropowder, 10 parts of calcium aluminate cement, additives 0.5 servings.

[0007] The low-cement-bonded castable according to the invention has an adjusted matrix structure to ensure high strength and volume stability of the castable. It is suitable for the working lining and composite lining of industrial furnaces, and is suitable for large, medium and small cement rotary kilns and industrial metallurgical kiln linings that require high temperature and high strength; some of them are made of used waste refractory materials, which are environmentally friendly and energy-saving.

[0008] The following table is a product of the present invention and a prior art product performance index comparison table:

[0009] .

[0010] As can be seen from the above table, t...

Abstract

The invention provides a low-cement-bonded casting material. The low-cement-bonded casting material is prepared by the following components in parts by weight: 60 parts of bauxite aggregate, 15 parts of bauxite clinker, 9 parts of silica micropowder, 6 parts of alumina micro powder, 10 parts of calcium aluminate cement and 0.5 part of an additive. The low-cement-bonded casting material provided by the invention has the advantages that on the basis of low-cement casting materials and by scientific grain grading and the ratio of ultrafine powder and fine powder, the components of matrix are controlled; compared with the low-cement refractory casting material, the content of CaO in the low-cement casting material is less than 2.5%. The low-cement-bonded casting material has the beneficial effects that the normal-temperature and medium-high-temperature strength is high, and the stripping resistance, the wear resistance and erosion resistance of a lining body are improved.

Description

technical field [0001] The invention relates to a low-cement bond castable, which belongs to the technical field of machinery. Background technique [0002] The existing low-cement bonded castables are constructed by vibration and smearing, and the performance of refractory materials depends on production and construction. However, due to the problems of the product itself, even if the construction requirements are strict and the construction is good, the strength of the lining body will not be strong enough, the stability will not be enough, and it will not even meet the requirements for use, and the existing low-cement bonded castables are not environmentally friendly. Energy-saving products. Contents of the invention [0003] The invention provides a low-cement bond castable, on the basis of the low-cement castable, through scientific particle gradation and the ratio of ultrafine powder and fine powder, the matrix components are controlled. Compared with low cement re...
