Description
Technical field
The invention belongs to technical field of refractory materials, more particularly, to a kind of magnesium slag abrasion-proof and refractory pouring material.
Background technology
Compared with qualitative refractory product, unshape refractory with castable refractory as representative has that technological process is short, energy consumption and low cost, easy to use, applied widely, globality and the advantage such as using effect is good, thus worldwide developed rapidly, its shared proportion more and more higher in whole refractory material.In the advanced country of some refractory technologies, the yield of unshape refractory is already close to the yield being even more than setting product.For example, the ratio that Japanese unshape refractory yield accounts for whole refractory material at present has reached 60% about；The U.S. for 50% about；English, moral, Fa Deng state are 40% ~ 50%.Nowadays, castable refractory has been widely used in the high-temperature service of the industrial circles such as metallurgy, building materials, electric power, chemical industry.
In addition, with the growth year by year of world's magnesium metal consumption demand, magnesium metal industry is in China's high speed development.But magnesium metal industry, while China's high speed development, also brings a series of environmental problem.Produce the industrial residue discharged during magnesium metal in China, a lot of magnesium factories are all to lose as waste, especially the less manufacturing enterprise of some scales.A large amount of discharges with magnesium slag are piled up, and not only occupy substantial amounts of land resource, and magnesium slag causes strong influence with the shower remittance rivers and lakes of rainwater to crops and surrounding, seriously injures the healthy of the mankind and the growth of crops.The research at present magnesium slag being recycled is concentrated mainly on by the use of magnesium slag burden calcining cement clinker and uses as active addition of cement.
Content of the invention
In view of this it is necessary to provide the magnesium slag abrasion-proof and refractory pouring material that a kind of utilization magnesium slag produces.
A kind of magnesium slag abrasion-proof and refractory pouring material, including the raw material of following mass fractions：20～30 parts of aggregates, 60～70 parts of powders, 10～15 parts of additives, described aggregate is made up of corundum, carborundum and mullite；Described powder is by α～Al2O3Powder, magnesium ground-slag composition；Described additive is water soluble phenol resin.
The solution have the advantages that：Silicon dioxide, calcium oxide, mgo refractory is contained in magnesium ground-slag, formed after magnesium ground-slag is mixed with water soluble phenol resin simultaneously and generate hydrated calcium silicate gel, the curing rate of magnesium slag abrasion-proof and refractory pouring material so can be improved, simultaneously phenolic resin bonded corundum, carborundum and mullite, α～Al2O3Powder, so in high temperature environments, α～Al2O3Powder generates new magnesium aluminate spinel with oxidation reactive magnesium, and newly-generated magnesium aluminate spinel is combined closely with unreacted material, strengthens the mechanical strength of magnesium slag abrasion-proof and refractory pouring material.
