Description

A kind of preparation method of the compound anti-erosion abrasion-proof and refractory pouring material of titanium
Technical field
The invention belongs to technical field of refractory castable, in particular to a kind of compound anti-erosion abrasion-proof and refractory pouring material of titanium Preparation method.More particularly to a kind of preparation side applied to cement kiln refractory lining titaniferous anti-erosion abrasion-proof and refractory pouring material Method.
Background technique
In recent years, utilization of the industrial waste on refractory material has been made significant headway, and industrial waste is made by processing It is applied in refractory material be one of the important means of industrial waste recycling for refractory raw material.
Ferrotianium slag is the byproduct generated in the smelting process of ferro-titanium, and smelting produces ferro-titanium mistake outside furnace The ratio of Cheng Zhong, ferro-titanium and ferrotianium slag is generally in 1:1 or so, and after recycling treatment, which is actually one kind Based on titanium calcium aluminate, calcium hexaluminate, Calcium dialuminate and calcium titanate are secondary high-melting-point compound phase material, and the present invention is contained with this Titanium compound material prepares a kind of cement kiln liner anti-erosion abrasion-proof and refractory pouring material.The titanium compound material existing market is referred to as Titanium calcium aluminate, appearance are black or dark brown solid, and hardness is big, and section is bright, stable under field conditions (factors), not with air and water Reaction.Refractoriness is greater than 1790 DEG C, is adapted as refractory raw material use.Particle volume density >=3.25g/ of titanium calcium aluminate cm3、Al2O3Content >=72%, TiO2Content >=10%, CaO content >=10%, the characteristic for having thermal expansion coefficient to reduce, can be used as The substitute of part alumina or Brown Alundum can greatly save cost of material, improve the profit of traditional refractory product, obtain preferable Economy and using effect.Currently, about titanium calcium aluminate in refining vanadium inner lining of furnace prefabricated component, bottom of steel ladle castable, ladle The correlative study applied in the refractory products such as inner lining pouring material, stemming and iron hook castable.
MS1250 micro mist be it is a kind of it is selected using Particular craft, be process with continuous ionic exchange and have perfection The just spherical novel ultra micro volcanic ash powder body material for being practically free of cellular substance.Due to MS1250 have it is continuous and uniform Particle diameter distribution, partial size can optimize castable microstructure generally between 0.1 μm to 5 μm, encrypt castable more It is real, promote that material is impervious, erosion-resisting characteristics.The chemical index of MS1250 micro mist is Al2O3Content is in 13%-20%, SiO2Content In 50%-60%, Fe2O3Content is in 4%-10%, CaO content≤15%, content of MgO≤2%.
Titanium elements are considered impurity component in traditional refractory material, so to control the chemical composition content of titanium dioxide. The alkaline erosion performance of tradition High-Alumina alumina raw used for refractory material is poor, needs to cooperate expensive silicon carbide etc. is anti-to invade Corrosion good raw material improves alkali resistance.Breaking conventional conception of the present invention, for the item of cement kiln liner anti-erosion and wearability Part requirement, in conventional cement kiln with introducing the high titanium calcium aluminate raw material of Ti content in aluminium silicon systems unshape refractory and anti-invade Erosion micro mist MS1250 micro mist reduces material cost, improves material property, promotes composite refractory development.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation methods of the compound anti-erosion abrasion-proof and refractory pouring material of titanium, solve biography It unites the intensity of castable refractory, alkali resistance and the poor problem of wearability.
A kind of preparation method of the compound anti-erosion abrasion-proof and refractory pouring material of titanium, specific step and parameter are as follows:
1, raw material prepare, and primary raw material includes titanium calcium aluminate, 80 bauxite clinkers, white alundum powder, silicon ash, MS1250 micro mist With pure calcium aluminate cement (CA70), dosage is prepared according to the following percentages by weight:
The sum of mass percent of above-mentioned material is 100%, and on this basis, preparation accounts for gross weight mass percentage content 0.01% -0.5% explosion-proof fiber, 0.01% -0.5% sodium tripolyphosphate and 0.01% -0.05% citric acid.
2, by above-mentioned mass percent that varigrained titanium calcium aluminate, 80 bauxite clinkers, white alundum powder, flint clay is micro- Powder, α-Al2O3Micro mist, MS1250 micro mist, silicon ash and explosion-proof fiber are uniformly mixed in batch mixer, mixture A are formed, after weighing It is packed into big polypropylene plastics pocket；
3, pure calcium aluminate cement (CA70) is uniformly mixed in batch mixer in proportion with sodium tripolyphosphate and citric acid, shape At mixture B, with close in the big polypropylene plastics pocket for being reloaded into step 2 after polypropylene plastics bag hermetic package after individually weighing Envelope；
4, it is mixed evenly in use, each Bag Material in packaging is poured into forced mixer, 6%~6.5wt% is added Water stir into pourable castable refractory.
Conserving 3 days or more after molding construction can come into operation.
The present invention has the advantages that the compound anti-erosion abrasion-proof and refractory pouring material properties of titanium of preparation are superior to traditional water Stall alumina-silica castable refractory, intensity is high, and Linear change rate is low after burning, and wear-resisting value is less than 5cm3, alkaline resistance properties reaches level-one.
