Abstract
The invention discloses a continuous-casting flame-proof argon-blowing brick, which comprises the following steps: blending electro-melting zirconium-corundum, electro-melting zirconium mullite, activated alumina powder, electro-melting alumina, chromic oxide powder and additive according to weight percentage; pre-mixing; stirring; moulding; drying; sintering; obtaining the product with brushing-proof, etching-proof and excellent air permeability.
Description
Technical field
The present invention relates to a kind of continuous casting with functional refractory product argon-blowing narrow brick.
Background technology
Argon-blowing narrow brick is positioned at the tundish bottom, and molten steel injects the head piece end of upper nozzle brick, is the functional refractory materials of refining high-purity " Clean Steel " usefulness.
When watering steel, the Argon Bubble of argon-blowing narrow brick evenly floats from the bottom, can promote inclusion to get rid of, eliminate cast initial stage molten steel and increase hydrogen, oxide inclusion reduces makes non-metallic inclusion content reduce significantly, the molten steel of handling through external refining injects after the tundish like this, accurately handles by argon-blowing narrow brick again, and molten steel is further purified.
Summary of the invention
The object of the present invention is to provide not explosion in a kind of baking and the use, anti-ly wash away, anti-erosion, functional refractory materials argon-blowing narrow brick that permeability is good.
For achieving the above object, the present invention realizes by following scheme:
Argon-blowing narrow brick is characterized in that the raw material of described argon-blowing narrow brick is formed by following weight part proportioning:
Electric fused zirconium corundum: 40～50 parts
Grain diameter is respectively 0-1mm, and the 1-3mm part by weight is 1: 2;
Fused zirconia-mullite: 20～30 parts
Grain diameter is respectively 0-1mm, and the 1-3mm part by weight is 1: 2;
Active oxidation aluminium powder: 5～10 parts
Fused alumina: 5～10 parts
Chromium sesquioxide powder: 3-4 part
Wedding agent: JN30 silicon sol 5-7 part.
The manufacturing process of above-mentioned argon-blowing narrow brick is:
1) premix: electric fused zirconium corundum in the above-mentioned raw materials technology and fused zirconia-mullite particulate material are mixed by described particle diameter proportioning;
2) stir: the premix particulate material is added the JN30 silicon sol by described proportioning stir, continue to stir by described weight part proportioning interpolation active oxidation aluminium powder, fused alumina, chromium sesquioxide powder then, evenly agglomerating until grog;
3) moulding: the pug that will stir after the maturation is put into special mould extrusion molding;
4) drying: the argon-blowing narrow brick after the moulding is put into 100 ℃ of oven dry of loft drier;
5) burn till: have the argon-blowing narrow brick of hardness to put into the high temperature kiln after will drying and burn till for 1700 ℃.
Advantage of the present invention is:
1) permeability is good.Molten steel injects the head piece place of upper nozzle brick, and the argon gas microbubble forms " air curtain wall " together, and Argon Bubble is eliminated cast initial stage molten steel and increased hydrogen evenly from the bottom come-up, promotes inclusion floating, has reduced the content of non-metallic inclusion significantly, further purify hot metal.
2) anti-erosion, abrasion resistance can be strong.Washed away in 20 hours through high-temperature molten steel, corrode layer less than 5mm, melting loss is less than 0.5mm.
3) configuration design is reasonable, convenience quick for installation, and apparent size is accurate.
4) be applicable to refining all steel kind.
