Description

A kind of high carbon black environmental protection castable in main trough
【Technical field】
The present invention relates to the technical field of refractory material manufacture, especially a kind of technologies of high carbon black environmental protection castable in main trough Field.
【Background technique】
With the development of steel new technology, steel and iron industry refractory technology there has also been epoch-making transformation and development, Steel plant both domestic and external greatly develop ironmaking technology, and blast furnace dischargeable capacity is continuously improved, and many smelting technique progress improve The load of tapping system leads to the extension of iron time, and tapping interval time is short, increases the erosion damage journey of iron tap channel refractory material Degree, proposes the requirement of long-life with resistance to material to blast furnace iron outlet groove.The carbon source of castable is based on pelletted pitch at present, Er Qiezhong It is well known, the substance being harmful to the human body is contained in asphalt stock, white cigarette, tobacco pollution environment can be generated in baking process.
【Summary of the invention】
The object of the invention is to solve the problems of the prior art, a kind of high carbon black environmental protection castable in main trough, energy are proposed Castable in main trough is enough set to have good erosion resisting, abrasion resistance and very good antioxygenic property, long service life to toast White cigarette, tobacco, therefore energy conservation and environmental protection will not be generated in journey.
To achieve the above object, the invention proposes a kind of high carbon black environmental protection castable in main trough, including following components and each The mass ratio of component is：50~70 parts of premium high-alumina alumina；20~30 parts of electro-corundum；30~40 parts of Brown Alundum fine powder；Titanium 5~10 parts of white powder；10~15 parts of nanoscale carbon black；3~5 parts of dispersing agent；10~15 parts of aluminium fine powder；10~15 parts of coagulant；It is multiple Close 6~8 parts of water-reducing agent；20~30 parts of carbide fine powder.
Preferably, the dispersing agent is by hexenyl bis-stearamides and silica solution according to 3:5 mass fraction mixing and At.
Preferably, the coagulant is by sodium metasilicate and potassium silicate according to 3:The mixing that 1 mass fraction mixes Object.
Preferably, the composite water-reducing agent is made of powder polycarboxylate, sodium sulphate and filler material according to 1:2:5 matter Amount number mixes.
Preferably, the mass ratio of each component is：50 parts of premium high-alumina alumina；20 parts of electro-corundum；Brown Alundum 30 parts of fine powder；5 parts of titanium dioxide；10 parts of nanoscale carbon black；3 parts of dispersing agent；10 parts of aluminium fine powder；10 parts of coagulant；Composite water-reducing agent 6 Part；20 parts of carbide fine powder.
