The temperature of preheating described in step 3) is 400～600 ℃.The object of copper coin being carried out to preheating is the temperature difference between copper zinc while reducing cast; If the preheat temperature of copper coin is too low, do not reach the effect of preheating; Ruo Taigao, can cause surface oxidation serious, hinders diffusion, is unfavorable for metallurgical binding.
Copper coin described in step 3) is process surface treatment before preheating.
Described surface treatment is to make copper coin pass through successively polishing, alkali cleaning, washing, pickling, washing, alcohol cleaning treatment.
The roll drafts of rolling described in step 3) is 20%～50%.
Mill speed described in step 3) is 50～100mm/min.
A kind of complex plate strip casting apparatus of realizing above-mentioned preparation method, comprise crucible, vibration pulping device, heat conduction roller and rolling device, the bottom of described crucible is provided with liquid outlet, this liquid outlet is connected with the liquid-inlet of vibration pulping device, and the slurry outlet of described vibration pulping device is to Continuous Casting Square to inclination; Described heat conduction roller is positioned at the below of the slurry outlet of vibration pulping device, for making base plate access carry out the slurry of the slurry outlet of self-excited oscillation pulping device; Described heat conduction roller and rolling device are along Continuous Casting Square to being arranged in order.
In described crucible, be provided with and control the stopper that liquid outlet opens and closes.
Complex plate strip casting apparatus, adopt vibration pulping device and traditional casting apparatus to be coupled, prepare fast satisfactory high-quality semi solid slurry, semisolid-solid-state metal composite and the continuous production of complex plate strip have been realized, greatly improved the production efficiency of complex plate strip, simple to operation, be applicable to large-scale industrial production.
The preparation method of copper zinc complex plate strip of the present invention, zinc liquid is first made to semi-solid slurry, under stress metallurgical compound with In Crystal Solid Copper again, reduce the pouring temperature of zinc liquid, carry out semisolid cast, effectively reduce the temperature difference between copper zinc, the diffusion of copper zinc slowly, easily form copper zinc solid solution, finally form metallurgical binding and do not form intermetallic compound; Required time when shortening copper zinc solid/liquid interfaces and reaching thermal balance, the heat that copper coin is warmed up to the required absorption of thermal equilibrium temperature reduces, the energy that zinc liquid discharges when solidifying reduces, reduce copper zinc diffusion rate and shorten diffusion time, combination interface layer easily forms solid solution, the combination interface layer forming is thinner, and thickness is lower than 10 μ m; Solved directly zinc liquid and copper coin have been carried out to the problem that combination interface layer is thicker, composite plate intensity is low that compound tense causes; Greatly improve the intensity of complex plate strip; In addition, semisolid metal processing technology can integrate with mutually with nearly clean process technology, can produce the complex parts blank of high-quality, this precision, satisfactory mechanical property.
The preparation method of copper zinc complex plate strip of the present invention, has solved the problems such as copper zinc laminating production environment is poor, technological process is long, efficiency is low, has obviously improved the metallurgical binding quality of copper zinc complex plate strip; Effectively improve the intensity of copper zinc complex plate strip, and realize continuously and producing.
