Abstract
A zircon sand carbon brick, has its chemical components (mess ratio) as follows: zircon sand:50~90%, zirconium oxide material whose purity is higher than 90%: 0~40%, carbon material: 1~15%, resin : 2~6%; the carbon substances are graphite or carbon black, the inhibitor comprises of one or several kinds of metal silicon, metal aluminum and boron carbide, the resin is phenolic resin . The invention has outstanding performances such as resistance to molten steel, to acid cinder, heat vibration and oxidation resistance, will not pollute molten steel in container for line steel, spring steel and other steel, has long service life, meet the requirements completely.
Description
Technical field
The present invention relates to a kind of refractory materials, when particularly smelting steel grade such as wire for steel cord of tyre, spring steel as containing the fire proof material brick that the steel in water container liner is used.
Background technology
Because the steel cord is with the silk footpath very little (generally all below 0.3mm) of finished product steel wire, when steel grades such as smelting wire for steel cord of tyre, spring steel, if size is mingled with (as Al greater than 5 the rigid of μ m in the steel
2O
3Deng) quantity more for a long time, the wire broken rate in the drawing twisting process will be difficult to control.For fragility trapped oxide in the steel, nitride, titaniferous compound content are reduced as far as possible, residual micro-brittle inclusion size reduces to and is not enough to the drawing fracture of wire is produced below the 5 μ m of harm, processing requirement is selected steelmaking feed and the refractory materials and the inclusion modification processing furnace outer refining process of ultralow AI, Ti content for use, and adopts Ca/Si than the acid insulating covering agent that is 0.9～1.1.
Existing ladle mainly contains the brick of zircon brick (Chinese patent CN87101328A), magnesia carbon brick and aluminum oxide and mould material as aluminate or alumina-magnesia castable (Chinese patent CN1337376A), Al2O3MgOC Bricks, high alumina brick, Unburnt Al2O3MgO Bricks etc. with inner lining material.
When adopting salic brick and mould material to use as lining material in the ladle, all wire for steel cord of tyre is produced and pollute, form rigid alumina inclusion, so can not satisfy service requirements.When adopting magnesia carbon brick to use as lining material in the ladle, exist easily and the acid slag reaction, damage is serious, the shortcoming that work-ing life is quite short.When adopting zircon brick to use as lining material in the ladle, there is the shortcoming of anti-molten steel, slag penetration resistance difference, work-ing life is also quite short.
Summary of the invention
The purpose of this invention is to provide a kind of zircon carbon brick, it has splendid anti-molten steel and corrodes, resistance to acid slag, anti-thermal shock and antioxidant property do not pollute molten steel when containing the steel in water container liner with brick when smelting steel grade such as wire for steel cord of tyre, spring steel, and the life-span are quite long.
For achieving the above object, it is main raw material that the present invention adopts zircon material, carbon class material, and adding zirconia material and an amount of antioxidant, as metal Si, metallic aluminium, and norbide etc., employing resol is wedding agent, through mix, moulding and be lower than under 500 ℃ the temperature drying and produce.
The chemical ingredients of zircon carbon brick following (mass percent):
Zircon: 50～90%
Purity is greater than 90% zirconia material: 0～40%
Carbon class material: 1～15%
Antioxidant: 0.5～5%
Resin (adding): 2～6%
Wherein, described carbon class material is graphite or carbon black.
Described antioxidant is a kind of or several compositions in Pure Silicon Metal, metallic aluminium and the norbide etc.
Described resin is a resol.
Beneficial effect of the present invention
It is main raw material that the present invention adopts zircon, zirconium white, carbon class material, and resol is wedding agent, adds the prepared zircon carbon brick of antioxidant, has higher intensity and antioxidant property in the temperature range of normal temperature～1650 ℃; And, have splendid anti-molten steel and corrode resistance to acid slag, anti-thermal shock and antioxidant property.It has as lining material in the ladle when smelting wire for steel cord of tyre, spring steel does not pollute molten steel, and work-ing life is longer than magnesia carbon brick and zircon brick.
In addition, compare with salic brick or mould material, the present invention does not in use produce the advantage of rigid alumina inclusion.
Embodiment
The specific embodiment of the invention sees Table 1.
Table 1 is listed the composition (weight percentage) and the characteristic of zircon carbon brick; Table 2 is listed the composition (weight percentage) and the characteristic of zircon brick, alumina-magnesia castable.
From table 1, table 2 as can be known, the present invention has splendid anti-molten steel erosion, resistance to acid slag, anti-thermal shock and antioxidant property.It has as lining material in the ladle when smelting wire for steel cord of tyre, spring steel does not pollute molten steel, and work-ing life is longer than magnesia carbon brick and zircon brick.
