The density of the aluminium dihydrogen phosphate aqueous solution is 1.0~2.0g/cm3。
Further, described pink fused alumina chamotte, including major ingredient and additive, the major ingredient preferably comprise following weight The raw material of percentage：
The additive includes sodium carboxymethylcellulose, yellow starch gum and phosphate dihydrogen aluminum solution, and each component accounts for the weight of major ingredient Amount percentage is respectively preferably：Sodium carboxymethylcellulose 0.2~0.5%, yellow starch gum 0.3~0.6%, aluminium dihydrogen phosphate aqueous solution 20~23%.
Further, described pink fused alumina chamotte, including major ingredient and additive, the major ingredient preferably comprise following heavy Measure the raw material of percentage：
The additive includes sodium carboxymethylcellulose, yellow starch gum and phosphate dihydrogen aluminum solution, and each component accounts for the weight of major ingredient Amount percentage is respectively preferably：Sodium carboxymethylcellulose 0.2%, yellow starch gum 0.5%, aluminium dihydrogen phosphate aqueous solution 22%.
α~the Al2O3The particle diameter of micro mist is<5μm.
The yellow starch gum is 200 mesh.
Present invention also offers the preparation method of described pink fused alumina chamotte, the preparation method comprises the following steps：Will Each solid material of formula ratio is added in slurry mixer and is kneaded, and phosphate dihydrogen aluminum solution, total mixing time is added dropwise in mixing process >=20 minutes.
In the formula of pink fused alumina chamotte disclosed by the invention, pink fused alumina system ensures there are enough resistant to corrosion during use Property and sintering strength, select suitable granularity ensure chamotte storage during not free settling, while add suitable additive To ensure that chamotte has appropriate viscosity.The determination of different material specification and ratio consider the performance of product, property of raw material and The factors such as production cost, white fused alumina provide high refractoriness and corrosion resistance, chromium oxide powder enhancing high-temperature anti-corrosion as aggregate Property, α-Al2O3Improve chamotte viscosity, sodium carboxymethylcellulose and yellow starch gum are as sticking during bonding agent prevents that chamotte from depositing Delaminating deposition, phosphate dihydrogen aluminum solution generate aluminum phosphate so as to obtain higher high-temperature behavior with corundum phase reaction.
The reasonable mixture ratio of raw material, the manufacturing are simple in the formula of pink fused alumina chamotte disclosed by the invention, resting period length. The pink fused alumina chamotte of preparation wraps use in the steel mill of horse steel first, and scene reflection workability is good, viscosity is suitable, resistant to corrosion Property strong (15 stoves offline then ooze steel about 5cm or so), be effectively improved the production efficiency of Ferrous Metallurgy.
