Abstract
The invention discloses a sealing cup refractory material for a continuous casting ladle long nozzle and a manufacturing method thereof. The sealing cup refractory material comprises a cup-shaped framework and a main body around the cup-shaped framework, wherein, the main body comprises the following components in percentage by weight: 50-75% of Al2O3, 3-10% of zirconium, 1-5% of carbon, 20-45% of a liquid phenolic resin binding agent and 1-5% of an organic additive. The refractory material of the invention is soft and in a cup shape, thus being convenient for construction operation, improving sealing property, slag resistance and infiltration resistance of molten steel, and avoiding oxygenation to steel due to air admission during the molten steel casting process.
Description
Technical field:
The present invention relates to make steel industry, belong to a kind of sealing refractory material that the continuous casting of molten steel ladle long nozzle is connected with the mouth of a river under the ladle specifically.
Background technology:
A kind of sealing refractory material of being connected with the mouth of a river under the ladle of continuous casting ladle long nozzle is aluminium-siliceous asbestos thing in the market, this product is owing to be alumina-silica fiber, hard, in use owing to easy efflorescence under poor sealing, not anti-molten steel erosion, non-refractory, the high temperature, the cavity in use appears easily, thereby air is sucked in the molten steel, make oxygenation in the steel, had a strong impact on steel quality.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of a kind of bowl-shape, software refractory material that the continuous casting ladle long nozzle is connected with the mouth of a river under the ladle that be used for.The technical scheme that it adopts is: a kind of sealing cup refractory material for continuous casting ladle long nozzle, comprise bowl-type skeleton and the body that is enclosed on the bowl-type skeleton, and wherein said body contains by weight percentage: 50～75%Al
2O
3, 3～10% zirconiums, 1～5% carbon, 20～45% liquid phenolic resin bonds and 1～5% organic additive.
The further technical characterictic of the present invention is:
Described aluminium oxide is provided by in bauxite, electric smelting or sintered alumina, the mild-clay one or more.
Described organic additive is the high molecular polymer powder.
Described high molecular polymer powder is made of in PEF fiber, polypropylene fiber and the stearic acid powder one or more.
Described carbon is provided by the liquid phenolic resin of carbonization.
Described zirconium is provided by zircon sand.
Described zircon sand is the zircon sand of zirconia weight percent content 〉=65%.
Described bowl-type skeleton is steel wire bowl-type skeleton or rigid plastics bowl-type skeleton or ceramic bowl-type skeleton.
The present invention also provides a kind of manufacture method of sealing cup refractory material for continuous casting ladle long nozzle, comprises the steps:
1) aluminium oxide and zircon sand are mixed by proportioning;
2) add the organic additive powder again to above-mentioned batching, stir;
3) add the liquid phenolic resin bond at last,, add press moulding on the bowl-type skeleton, stamp out bowl-shape, software refractory material by vibration through the mixed grind of strong formula muller through 60～80 minutes.
The invention has the beneficial effects as follows: because a kind of sealing cup refractory material for continuous casting ladle long nozzle provided by the present invention is the software refractory material, be convenient to construction, construction good airproof performance, and since material of the present invention be aluminum-zirconium-carbide refractory, therefore than existing product refractoriness height, can not occur efflorescence in the use, can not form the cavity, improve resistance to slag, the infiltration of anti-molten steel, avoid molten steel in steel pouring process, to make steel oxygenation, and preserve under the normal temperature and still can use in 1 year owing to entering air.
The specific embodiment:
The invention will be further described below in conjunction with specific embodiment:
Embodiment 1)
As shown in table 1: that 50 parts of bauxites, fused alumina, mild-clay mixture and 10 parts of zircon sands are mixed, to above-mentioned mix batching in add 5 parts of PEF fibers again, stir, add 35 parts of liquid phenolic resin bonds at last, through the mixed grind of forced action type muller through 60～80 minutes, add press moulding on steel wire bowl skeleton by vibration, stamp out obturating cup refractory material bowl-shape, software.Because the carbon in the obturating cup refractory material is a kind of of liquid resin carbonization, so do not need other adding.
Embodiment 2)
As shown in table 1: that 75 parts of bauxites, sintered alumina, mild-clay mixture and 3 parts of zircon sands are mixed, to above-mentioned mix batching in add 1 part of polypropylene fiber again, stir, add 21 parts of liquid phenolic resin bonds at last, through the mixed grind of forced action type muller through 60～80 minutes, add press moulding on steel wire bowl skeleton by vibration, stamp out obturating cup refractory material bowl-shape, software.Because the carbon in the obturating cup refractory material is a kind of of liquid resin carbonization, so do not need other adding.
Embodiment 3), embodiment 4) and embodiment 5) reference table 1 and embodiment noted earlier be similar, be not described in detail in this.
