Abstract
The invention relates to a refractory material, and in particular relates to a corundum-magnesium aluminate spinel refractory material which is prepared from raw materials, including corundum, magnesium aluminate spinel, fused magnesite and alpha-Al2O3 micro powder. The corundum-magnesium aluminate spinel refractory material is relatively high in refractoriness and strength, good in anti-erosion property, anti-stripping property and anti-slag property, good in thermal vibration stability and long in service life, thereby being a corundum-magnesium aluminate spinel refractory material with excellent quality.
Description
Technical field
The present invention relates to a kind of refractory materials, especially a kind of corundum-magnesia-alumina spinel refractory.
Background technology
Aluminium is very active metal, is easy to and the Fe in alumine fire resistant materials
2o
3, SiO
2deng impurity component generation reduction reaction, cause aluminium liquid to the erosion of refractory materials, reduce the life-span of refractory materials.Aluminium liquid has good wettability to alumine fire resistant materials simultaneously, and aluminium liquid infiltrates the inner rear oxidation of refractory materials along apparent pore and expands, and causes refractory materials inside to produce tiny crack, forms vicious cycle, cause refractory life to reduce.Along with the development of aluminum smelting industry, the raising require aluminium liquid purity and the requirement of aluminium metallurgy refractory life, need to develop new refractory materials to replace the high alumina refractories of current widespread use.Corundum and magnesium-aluminium spinel not easily with aluminium liquid generation chemical reaction, and magnesium-aluminium spinel has good corrosion resistance.
Summary of the invention
The present invention is intended to solve the problem, and provide a kind of corundum-magnesia-alumina spinel refractory, its refractoriness is high, and corrosion resistance is good by force, and long service life, and its technical scheme adopted is as follows:
A kind of corundum-magnesia-alumina spinel refractory, its raw material comprises corundum, magnesium-aluminium spinel, electrosmelted magnesite clinker, α-Al
2o
3micro mist, the mass percent of each component is: corundum 55%, magnesium-aluminium spinel 20%, electrosmelted magnesite clinker 8%, α-Al
2o
3micro mist 17%; Described corundum is white fused alumina; The apparent porosity of described corundum-magnesia-alumina spinel refractory is 20%, and volume density is 2.99g/cm
3, refractoriness is 2125 DEG C.
Tool of the present invention has the following advantages: white fused alumina is the main raw material producing medium-to-high grade ambiguity and amorphous refractory, color and luster is pure white, sparkling and crystal-clear brilliant, there is the advantages such as compact structure, volume density is large, void content is low, effectively can improve the volume stability of material and thermal shock resistance, compressive strength, acid and alkali-resistance erosion, antistripping ability, anti-powdering; Magnesium-aluminium spinel has compared with high fusing point, thermal expansion is little, thermal stresses is low, heat shakes good stability, good corrosion resistance, resistive connection structure peel-ability and slag resistance; In sintering process, electrosmelted magnesite clinker and α-Al
2o
3micro mist reacts, fabricated in situ magnesium-aluminium spinel, and the spinel crystal grain of generation is tiny and fine and close, thus enhances matrix.Therefore, this refractory materials has higher refractoriness and intensity, good corrosion resistance, antistripping ability and slag resistance, and heat is shaken good stability, and long service life is a kind of corundum-magnesia-alumina spinel refractory of excellent quality.
Embodiment
Below in conjunction with example, the invention will be further described:
A kind of corundum-magnesia-alumina spinel refractory, its raw material comprises corundum, magnesium-aluminium spinel, electrosmelted magnesite clinker, α-Al
