【摘要】：針對立式澆鋁法制備銅包鋁復(fù)合鑄錠時(shí)存在的復(fù)合層上薄下厚以及復(fù)合層過厚的問題,本項(xiàng)目組提出了強(qiáng)制冷卻銅管內(nèi)鋁液來制備銅包鋁復(fù)合鑄錠的方法,并獲得了國家發(fā)明專利。為了利用這種方法制備出復(fù)合層上下均勻且薄的銅包鋁復(fù)合鑄錠,本文首先研制了立式強(qiáng)制冷卻銅管內(nèi)鋁液法制備銅包鋁復(fù)合鑄錠裝置,之后用該裝置成功地制備出了復(fù)合層上下均勻的銅包鋁鑄錠,并對復(fù)合層的形狀、厚度等進(jìn)行了研究。所研制的強(qiáng)制冷卻銅管內(nèi)鋁液法制備銅包鋁復(fù)合鑄錠裝置,構(gòu)造簡單、操作方便、運(yùn)行可靠,可制備出長度為500mm,直徑可任意調(diào)整的銅包鋁鑄錠。對復(fù)合層的研究發(fā)現(xiàn):(1)在選定的工藝參數(shù)范圍內(nèi),鑄錠內(nèi)復(fù)合層呈鋸齒形,但整體上厚度上下均勻一致;(2)工藝參數(shù)不影響復(fù)合層厚度的均勻性;(3)復(fù)合層厚度對工藝參數(shù)比較敏感;(4)當(dāng)復(fù)合層厚度較厚時(shí),復(fù)合層內(nèi)部易出現(xiàn)縮孔等缺陷;(5)在選定的工藝參數(shù)范圍內(nèi),最佳工藝參數(shù)為.鋁液溫度700℃,接觸時(shí)間40s,銅管壁厚3mm,導(dǎo)流孔孔徑8mm,噴水流量50L/min。
[Abstract]:In order to solve the problems of thin layer thickness and excessive thickness of composite layer in the preparation of copper-clad aluminum composite ingot by vertical aluminum casting, the project group proposed a method of forced cooling aluminum liquid in copper tube to prepare copper-clad aluminum composite ingot.And obtained the national invention patent.In order to prepare copper clad aluminum composite ingot with uniform and thin layers by this method, a device for preparing copper clad aluminum composite ingot with vertical forced cooling copper tube was developed in this paper.After that, the copper clad aluminum ingot with uniform upper and lower layers was successfully prepared, and the shape and thickness of the composite layer were studied.The device developed in this paper is simple in structure, convenient in operation, reliable in operation, and can be used to produce copper clad aluminum ingot with 500mm length and adjustable diameter.The study of the composite layer found that the composite layer in the ingot was serrated within the selected technological parameters.However, the thickness of the composite layer is more sensitive to the process parameters when the thickness of the composite layer is thicker, when the thickness of the composite layer is thicker, the thickness of the composite layer is not affected by the uniformity of the thickness of the composite layer.The optimum process parameters are as follows: in the range of selected process parameters, shrinkage holes and other defects are easy to appear in the composite layer.The temperature of molten aluminum is 700 鈩，
