Summary of the invention
The object of this invention is to provide a kind of preparation method of Copper-Aluminum compound strip, solve the problem that combination interface layer is thicker, composite plate intensity is low of directly aluminium liquid and copper coin being carried out compound tense and causing.
Second object of the present invention is to provide a kind of complex plate strip casting apparatus realizing above-mentioned preparation method.
In order to realize above object, the technical solution adopted in the present invention is: a kind of preparation method of Copper-Aluminum compound strip, comprises the following steps:
1) after aluminium ingot being removed surface impurity, under 680 ~ 780 DEG C of conditions, carry out melting, form aluminium liquid;
2) step 1) gained aluminium liquid is made semi-solid slurry;
3) by step 2) on gained slurry cast copper coin after preheat, rolling, to obtain final product.
The temperature of preheating described in step 3) is 300 ~ 600 DEG C.The object of carrying out preheating to copper coin is temperature difference when reducing cast between copper aluminium; If the preheat temperature of copper coin is too low, then do not reach the effect of preheating; Ruo Taigao, can cause surface oxidation serious, hinder diffusion, be unfavorable for metallurgical binding.
Copper coin described in step 3) is before preheating through surface treatment.
Described surface treatment makes copper coin successively through polishing, alkali cleaning, washing, pickling, washing, alcohol washes process.
