In the process of cold rolling, the oil residue on the surface of strip seriously affects the appearance quality of strip. The cold rolling mill of aluminum plate manufacturer is a domestic equipment, and there are few methods to remove oil from the surface of aluminum plate. Therefore, according to the production practice, the oil removal on the plate surface has been improved. The rolling line is increased by 20 mm. Oil guide plates are installed on both sides of the bottom of the air purification roller, and oil wiping devices with adjustable width are installed on both sides of the exit guide roller to reduce the oil pollution on the surface of the plate belt.
1. Surface oil of upper plate and oil transfer measures安装一个弧形挡油板的顶部支撑辊,这样石油从拱门不落在支撑辊,但沿着挡油板流空气滤清器,以及支撑辊动摇石油也流沿挡油板空气滤清器;吗?吗?(2)在空气滚筒清洁器上部与集油罩之间悬挂可移动的薄铝板，使油滴不能穿过空气滚筒清洁器溅在铝板上;吗?吗?(3)在空气滤清器滚筒底部两侧安装易拆卸的导油板，使空气滤清器滚筒上的油直接导向集油池。
Install a top supporting roller of arc-shaped oil baffle, so that the oil does not fall on the supporting roller from the arch, but flows along the oil baffle to the air filter, and the oil also flows along the oil baffle to the air filter when the supporting roller shakes; is it? Is it? (2) a movable thin aluminum plate is hung between the upper part of the air cylinder cleaner and the oil collecting cover, so that the oil drops cannot be splashed on the aluminum plate through the air cylinder cleaner; Do you? Do you? (3) install easily removable oil guide plates on both sides of the bottom of the air cleaner drum to direct the oil on the air cleaner drum to the sump.
2. Oil removal measures for lower plate surface(1)适当改善轧制线，目前轧机有20mm的调整空间.用空气吹板表面。(2)调整吹嘴位置，风压不低于0.5mpa，保证侧扫油效果(3)在出口偏导板两侧设置宽度可调的擦油装置。
(1) At present, the rolling mill has 20 mm adjustment space, and the surface of the plate is blown by air. (2) Adjust the position of the blowing nozzle, and the wind pressure shall not be less than 0.5MPa, so as to ensure the side oil cleaning effect. (3) set the oil wiping device with adjustable width on both sides of the outlet deflector.
3. Strengthen cold rolling and cross cutting groove cleaning(1)加强对冷轧通道的清洗，成品前必须清洗通道，清洗轧制通道;(2)在横切生产中合理控制喷油量，提高矫直机的清洗质量，有效降低横切油。
(1) To strengthen the cleaning of cold rolling channel, the channel and rolling channel must be cleaned before the finished product; (2) in the crosscutting production, reasonably control the injection quantity, improve the cleaning quality of the straightener, and effectively reduce the crosscutting oil.
