Abstract
The invention relates to aluminum-carbon-zirconium slide gate nozzle brick without calcinations process. The components are: the corundum with purity larger than 96%:60-85%, zirconium material whose content of zirconium oxide is larger than 25%: 5-35%, carbon material 1-10%, aluminum 0.5-5%, adds in a little antioxidant such as B4C, Si, and bond such as organic silicon modified phenol-formaldehyde resin, it is produced through compound mixing and forming under temperature less than 500deg.C. The producing period is short and it has no contamination. It has excellent normal temperature and high temperature intensity.
Description
Technical field
The present invention relates to a kind of aluminium carbon zirconium mass slide gate nozzle refractory material.
Background technology
Along with the development of process for making, slide gate nozzle is required to become harsh day by day with the service condition of refractory material.In order to improve the life-span of slide gate nozzle refractory material,, be necessary to prevent that for example liquid molten steel of it and melted material and slag from reacting even when refractory material contacts with melted material.The damage of sliding sprue tile for smelting is not only because the chemical action of liquid metal and slag, and since the Rapid Thermal of motlten metal impact the crackle that causes and peel off and the physical actions such as wearing and tearing of liquid metal.Therefore for nozzle brick can stably be operated, must adopt to have heat shock resistance and the good nozzle brick of erosion-resisting characteristics.
The sliding sprue tile for smelting that uses mainly contains and adds the Al that silicon metal powder burns till at present
2O
3-ZrO
2-C (as Japanese patent laid-open 11-36012), Al

3Carbon combined fire-resistant material such as-C and add polymethyl silicane or organic siliconresin is the alumina-carbon material that does not burn (as the flat 3-169477 of Japan Patent) of feature.Burnt aluminum carbon and aluminium carbon zirconium slide plate with the carbon combination can satisfy the instructions for use of steel mill substantially, but because elevated temperature strength is not high, still exist service life not long, sliding area plucking and the problem of pressing from both sides cold steel.In addition for the carbon combination burn till aluminum-carbon sliding, aluminium carbon zirconium slide plate, not only exist and burn till expense height, long shortcoming of production cycle, and after burning till, need oil immersion pitch, contaminated environment in process of production.Substantially can satisfy the instructions for use of medium and small ladle and tundish for the aluminum-carbon sliding that does not burn, but because thermal shock resistance is desirable not enough, using there are a considerable amount of radial cracks to produce, and still has long problem in service life on large-scale ladle.
Summary of the invention
The purpose of this invention is to provide the not aluminium carbon zirconium mass sliding sprue tile for smelting produced of firing technique of a kind of employing, and have normal temperature and elevated temperature strength height, anti-molten steel erosion, scour resistance, anti-oxidant and anti-thermal shock good.
For achieving the above object, a kind of employing of the present invention is the aluminium carbon zirconium mass sliding sprue tile for smelting of firing technique production not, and its component is (percetage by weight):
Purity is greater than 96% corundum 60～85%;
Zirconia content greater than 25% contain zirconia material 5～35%;
Carbon material 1～10%;
Metallic aluminium 0.5～5%;
Antioxidant 0.5～5%;
Bond adds 4～5%.
Wherein, the described zirconia material that contains is in fused alumina zirconia or the zirconium mullite material one or both.
The carbon content of described carbon material is greater than 95%.
Described carbon material is one or both in carbon black or the graphite material.
Described bond is the organic silicon modified phenolic resin, anti-oxidant good (" organic siliconresin process application " Luo Yanjun etc., Chemical Industry Press, P112,2002.1).
Described antioxidant is one or both among B4C, the Si.
Materials such as above-mentioned corundum, fused alumina zirconia, zirconium mullite, carbon black, metallic aluminium powder and other additives be raw material through mix, moulding and be lower than under 500 ℃ the temperature drying and produce.
Beneficial effect of the present invention is compared with the aluminium carbon zirconium mass sliding sprue tile for smelting that tradition is burnt till, and this sliding sprue tile for smelting has following characteristics:
1. need not burn till and oil immersion pitch, have advantage with short production cycle and free from environmental pollution;
2. have very high normal temperature and elevated temperature strength, and well anti-oxidant, anti-thermal shock and erosion-resisting characteristics, on large-scale ladle, to use, the life-span is longer.
The specific embodiment
The invention will be further described by the following examples.
Table 1 has been listed the composition and the characteristic of embodiments of the invention;
Table 2 is listed the composition and the characteristic of burning till aluminium carbon zirconium mass, unfired Al-C matter sliding sprue tile for smelting and is compared.
