Abstract
The invention provides a preparation process of a refractory plastic material. The process comprises a step of proportioning the raw materials in parts by mass: 60 parts of bauxite aggregates, 10 parts of alumina clinker powder, 6 parts of mullite powder, 9 parts of refractory clay, 5 parts of alumina micro powder, 10 parts of calcium aluminate cement and 0.5 part of an additive. The preparation process of the refractory plastic material provided by the invention does not generate the material damage problem, and thus the technical, economic and social benefits can be achieved that the construction procedure can be simplified, the working condition and environment are improved, the efficiency is improved, and the time limit for a project is shortened.
Description
Technical field
The present invention relates to a kind of plastic refractory manufacturing process, belong to cement technology field.
Background technology
The toughness that tradition plastic refractory is lower is lower, expands and seriously makes lining body impaired.In use procedure, scour resistance is weak, so cause lining body easily to peel off, life cycle shortens, and impact is produced, and economic benefit is not high.
Summary of the invention
The invention provides a kind of plastic refractory manufacturing process, soft plastic under plastic refractory normal temperature, pole is suitable for and is used at the different sites of boiler of power plant device shaped complexity; Tool microdilatancy under high temperature, is conducive to the overall tightness improving furnace wall, reduces heat-energy losses; Resistance to compression, High anti bending strength, improve useful life longevity; Compound additive raw material is easy to get, and easily prepares, and steady quality is reliable; Nontoxic, corrosion-free, do not pollute, do not burn.Make product, fortune, storage, with all safe and reliable; Construction operation is good, water operation and scene need not to mix formwork support process etc., does not need long-term maintenance simultaneously, there is not material breakage problem, thus simplification operational procedure can be received, improve working conditions and environment, raise the efficiency, the Technological Economies such as reduction of erection time and social benefit.
For solving above technical problem, the invention provides following technical scheme: a kind of plastic refractory manufacturing process, proportioning is carried out as follows: 60 parts, alumina aggregate according to mass ratio, 10 parts, bauxite clinker powder, mullite powder 6 parts, fireclay 9 parts, alumina powder 5 parts, aluminous cement 10 parts, additive 0.5 part; Mullite powder is worn into 180-320 order; The granularity of fireclay is 0.98 μm; The granularity of alumina powder is 3 μm-5 μm.
This plastic refractory manufacturing process that the present invention relates to, belong to phosphoric acid salt in conjunction with moldable, use temperature is high, and aluminum phosphate forms three-dimensional net structure in heat-processed, has stronger toughness and wear resistance, washing away of high speed ash-laden gas and material particles can be resisted, have excellent heat-resistant knocking stability, plasticity-is good, easy tamping, construction rear surface is smooth, not bulging.
Embodiment
A kind of plastic refractory manufacturing process, carries out proportioning according to mass ratio as follows: 60 parts, alumina aggregate, 10 parts, bauxite clinker powder, mullite powder 6 parts, fireclay 9 parts, alumina powder 5 parts, aluminous cement 10 parts, additive 0.5 part; Mullite powder is worn into 180-320 order; The granularity of fireclay is 0.98 μm; The granularity of alumina powder is 3 μm-5 μm.
Raw material is broken to be pulverized
Carried out brokenly by entered raw material pulverizing, raw material crushing becomes 5mm-3mm, 3mm-1mm, 1mm-0mm, and bauxite clinker is ground into 180 powder materials.All the other raw materials, enter all size raw material on request.
By production advice note requirement accurate feed proportioning.Guarantee during batching that two people are in factory, people's weighing, a people confirms.
The material prepared is dropped in stirrer.Start is stirred, churning time 5 ~ 8min.
The material discharging packaging stirred, every bag of 25Kg.
Product inspection method
Interventions Requested: volume density, thermal conductivity, compressive strength, folding strength and Linear change rate.
The method of inspection: sample method for making sample is undertaken by the regulation of YB/T5202.1; The mensuration of volume density is undertaken by YB/T 5200; The mensuration of thermal conductivity is undertaken by YB/T 059; The mensuration of the anti-folding of normal temperature, compressive strength is undertaken by YB/T 5201; The mensuration of Linear change rate is undertaken by YB/T 5203.
Inspection rule:
High-strength light gravity flow pouring material is with a collection of group, and batch weight is no more than 60t.The sampling of product is undertaken by GB/T17617.When having one not meet standard-required in assay, this defective item should be rechecked again, though result only have one defective, then by the gross as substandard product.
Test set:
This plastic refractory manufacturing process that the present invention relates to, soft plastic under plastic refractory normal temperature, pole is suitable for and is used at the different sites of boiler of power plant device shaped complexity; Tool microdilatancy under high temperature, is conducive to the overall tightness improving furnace wall, reduces heat-energy losses; Resistance to compression, High anti bending strength, improve useful life longevity; Compound additive raw material is easy to get, and easily prepares, and steady quality is reliable; Nontoxic, corrosion-free, do not pollute, do not burn.Make product, fortune, storage, with all safe and reliable; Construction operation is good, water operation and scene need not to mix formwork support process etc., does not need long-term maintenance simultaneously, there is not material breakage problem, thus simplification operational procedure can be received, improve working conditions and environment, raise the efficiency, the Technological Economies such as reduction of erection time and social benefit.
Following table is product of the present invention and prior art products performance index synopsis:
As seen from the above table, beneficial effect of the present invention is as follows:
1, quality light, be neutral plastic refractory materials, various aspects of performance is superior, meets every demand of producing.Suitable with like product.
2, high, the medium temperature intensity of product strength does not reduce, and directly can be used as working lining.Domestic like product intensity is low, medium temperature intensity declines.
3, construction process does not need vibration, reduces labour intensity and noise pollution.Ramming constructing operation is flexible, and convenient for various complicated construction thin-walled lining body construction, performance is better.
4, this product is in advanced level at present at home.
Embodiment of the present invention does not form the restriction to the application's scope; within every spirit in the present invention's design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection scope of the present invention.
