Can be compound at the single or double and the clad material of aluminum alloy base material according to producing needs.
Required clad material is by melting, casting, cold rolling, the matting preparation, clad material and aluminum alloy base material compound tense, according to the single or double composite demand clad material is placed on the uncoiling mechanism, the aluminum alloy base material melt is rolled production by lip at the casting roll shop building, after treating casting-rolling technology and casting-rolling aluminum alloy base material steady quality, send into clad material by the composite roll of the gap between lip and the casting roller or casting and rolling machine row and the slit on aluminum alloy base material surface, in aluminum alloy base material casting processing, carry out composite rolling synchronously and directly make aluminum-based multi-metal composite material, then by cold rolling with clad material, operation such as cut and make the aluminum-based multi-metal composite material finished product.
Above-mentioned method of producing aluminum-based multi-metal composite material with casting-rolling technology specifically may further comprise the steps:
(1) lip is installed: keep suitable mouth roller gap;
(2) the base material melt is prepared: adjust base material bath composition and temperature and reach base material casting production requirement;
(3) base material is rolling: start milling train, open the melt baffle plate and carry out the casting riser, set up stable continuous casting production status;
(4) import clad material to the aluminum alloy base material surface by the composite roll of gap between lip and the casting roller or casting and rolling machine row and the gap of substrate surface, clad material and aluminum alloy base material are carried out synchronous composite rolling by roll, when clad material enters the casting roller, adjust rolling mill speed according to producing needs; When clad material enters composite roll, adjust rolling mill speed and roll-force according to producing needs;
(5) by behind the composite rolling acquisition aluminum-based multi-metal composite material, again composite is carried out the cold rolling predetermined thickness that is machined to;
(6) aluminum-based multi-metal composite material after cold rolling is cut into the finished product of required width, warehouse-in is preserved.
For realizing carrying out the production of aluminum-based multi-metal composite material with casting-rolling technology, when sending into clad material by the gap between lip and the casting roller and carry out composite rolling, its production equipment mainly comprises chute, lip, upper and lower casting roller and uncoiling mechanism; In the upper and lower casting roller one or two is connected with uncoiling mechanism by clad material.
When the slit of composite roll by casting and rolling machine row and substrate surface was sent into clad material and carried out composite rolling, its production equipment mainly comprised chute, lip, upper and lower casting roller, upper and lower composite roll and uncoiling mechanism; Casting roller, composite roll list sequentially at a production machine and arrange, and one or two in the upper and lower composite roll is connected with uncoiling mechanism by clad material.
When utilizing method and apparatus of the present invention to carry out aluminum-based multi-metal composite material production, its beneficial effect is:
(1) casting-rolling technology produce aluminum-based multi-metal composite material than hot rolling technology production save ingot casting casting, mill operations such as face, combination, heating, shortened production procedure, simplified production technology.Therefore produce aluminum-based multi-metal composite material of the same race hot rolling technology is per ton on year-on-year basis and reduce production costs more than 1000 yuan.
(2) can not reduce the raw material loss because casting-rolling technology production aluminum-based multi-metal composite material does not mill face, not need heating and multi-pass hot rolling simultaneously yet, greatly reduce energy consumption.Therefore produce aluminum-based multi-metal composite material of the same race on year-on-year basis more than the hot rolling technology 1500KWh of economize on electricity per ton.
