Description
Technical field
The present invention relates to a kind of with Al-Ti-C silk fining agent production double-zero aluminum foil woolen cloth and preparation method.Belong to the aluminium foil processing technique field.
Background technology
The woollen production main method of double-zero aluminum foil has hot rolling aluminium foil stock, the direct continuous casting and rolling aluminium foil stock of electrolytic solution and aluminium ingot remelting continuous casting and rolling aluminium foil stock at present.Wherein hot rolling aluminium foil stock production technology is mainly produced aluminium foil stock through multi-pass large deformation hot-rolling method, and this method cost of investment is high, the factory building area is big, and it is slower to take effect, but quality product is highly stable; The direct continuous casting and rolling of electrolytic solution is to utilize 40 ~ 60% cold burdens and master alloy fining agent to produce aluminium foil stock; Compare the former have the investment little, the factory building area is little, aluminium foil stock production abbreviated system characteristics; Need a large amount of outsourcings but its cold burden is allocated into, increased buying and the handling cost and the metallurgical liver mass factors of instability in the middle of invisible; Aluminium ingot remelting continuous casting and rolling production technique is through the aluminium ingot remelting and utilizes 40% with interior cold burden and master alloy fining agent production aluminium foil stock; Have the investment little, the factory building area is little, aluminium foil stock production abbreviated system characteristics; Quality product is very stable; This technology has nearly 30 years history, and technology is very ripe at present.
In the prior art, the master alloy fining agent is generally three kinds of Al-Ti master alloys, Al-5Ti-B silk fining agent, Al-Ti-C silk fining agent.Mostly the former is hot rolling aluminium foil stock production use; The the two be mostly that direct continuous casting and rolling of electrolytic solution and the production of aluminium ingot remelting continuous casting and rolling aluminium foil stock uses; The third party is in developing period at present.The direct continuous casting and rolling of electrolytic solution is because molten aluminium temperature high (melt temperature＞755 ℃), melt overheat, Al-5Ti-B silk fining agent usage quantity very big (2.0～4.0kg/tAl), after its fusing, the TiB of formation
2Particle is deposited in the chute bottom easily, and waste is big and metallurgical quality is unstable, the at present main dependence on import of the Al-5Ti-B silk fining agent that this technology is used; Aluminium ingot remelting continuous casting and rolling is because molten aluminium temperature lower (700 ~ 750 ℃ of melt temperatures); Al-5Ti-B silk fining agent usage quantity less (1.5～2.5kg/tAl); The Al-5Ti-B silk fining agent that this technology is used is substituted by homemade nova Al-5Ti-B silk at present, and metallurgical quality is basicly stable.
Because homemade Al-5Ti-B silk fining agent has only nova one tame quality level in Shenzhen can reach the import level at present; Its price level still is in high price; And its quality product is divided several levels such as two zero paper tinsels, single zero paper tinsel, general plate; Classification is meticulous, defines not obviously from result of use product rank, produces fine double-zero aluminum foil woolen cloth and still has expensive and the unsettled risk of quality.
Al-Ti-C silk fining agent is the product innovation that China puts on market at present, and its production technology has been improved with stable, and this product is compared with the Al-Ti-B fining agent, has following advantage:
1. compare with the Al-Ti-B master alloy, the Al-Ti-C production process is pollution-free, is typical energy-saving and emission-reduction product;
2. owing to do not have potassium fluoborate or villiaumite to make raw material, thereby the Al-Ti-C master alloy is difficult for producing salt and is mingled with;
3. compare with present best in the world Al-5Ti-B, when the higher aluminium of refinement 1070 fine aluminiums or purity, have notable effect of crystal grain thinning more;
4. under same grain refining effect, Al-Ti-C introduces the hard point of less amount in molten aluminium, thereby alleviates the potential for adverse effects of pin hole increase probability in the aluminium foil calendering production process.
But, use Al-Ti-C silk fining agent, higher to the alloy manufacturing technique requirent, the production technique that conventional use Al-Ti-B fining agent prepares alloy can not meet the demands.
The present invention just is being based on the above-mentioned advantage of Al-Ti-C silk fining agent, utilizes Al-Ti-C silk fining agent own characteristic, in conjunction with the production practice of aluminium ingot remelting continuous casting and rolling, provides a kind of and produces 1235 alloy double, zero aluminium foil stock and preparation method thereof with the Al-Ti-C fining agent.
