Working principle of Quanzhou Panyu trading aluminum foil mill

Quanzhou Panyu trading aluminum foil rolling mill adopts negative roll gap rolling in the production of aluminum foil, which is different from other strip production methods. Generally, there will be a certain amount of roll gap in the production of ordinary strip, while aluminum foil rolling mainly depends on two work rolls. The force generated by two work rolls on aluminum foil will make it elastically deformed, and the rolling force exerted by the frame is also greater than the deformation resistance of metal, This reduces the influence of rolling force on aluminum foil thickness. At this time, aluminum foil thickness control is mainly controlled by rolling speed and uncoiling tension. Aluminum foil is special, with high requirements for raw materials, and it is easy to break the belt during production. Generally, the thickness of the material is only 0.1 ~ 0.2mm. It needs to be extruded and closed by the work roll, and then the aluminum foil has higher quality, wider width, thinner thickness and safer.

Basic composition of aluminum foil rolling mill

Generally speaking, the aluminum foil rolling mill is mainly composed of five parts: uncoiler, coiler, working base, transmission system, auxiliary equipment, etc. Among them, the composition structure of working base and auxiliary equipment is relatively complex, and the key is the control system. Without a perfect electrical control system, the thickness of aluminum foil cannot be ensured. Generally, aluminum foil rolling mill is divided into small rolling mill, medium rolling mill, large or wide rolling mill according to the width of the roll surface.
