大部分的铝卷生产厂家采取积极的热变形挤压成型方法通过特定的(锥死,死,死)来获得所需的横截面的形状铝,由于外部因素的影响点颜色铝辊在生产过程中会拖黑的缺陷,渣,所以如何解决这个问题,减少废料,提高收益率?这里有三种方法:
　　Most aluminum coil manufacturers adopt active hot deformation extrusion method to obtain the required cross-section shape of aluminum through specific (cone dead, dead, dead). Due to the influence of external factors, the spot color aluminum roll will drag black defects and slag in the production process, so how to solve this problem, reduce waste and improve the yield? Here are three methods:
　　1. 生产过程控制
　　1. Production process control
　　切割彩涂铝辊，用风管清理彩涂铝辊上的灰尘，减少灰尘的带入，减少黑、渣的来源;
　　Cut the color coated aluminum roller, use the air pipe to clean the dust on the color coated aluminum roller, reduce the introduction of dust, reduce the source of black and slag;
　　残余厚度要保持足够，过薄的残余压力会导致彩涂铝盘管在卷尾处卷入型材，造成黑、渣;
　　The residual thickness should be enough, too thin residual pressure will cause the color coated aluminum coil to be drawn into the profile at the end of the coil, resulting in black and slag;
　　挤出速度要有效控制，特别是挤出端部要减速，防止湍流卷入表面杂质。
　　The extrusion speed should be controlled effectively, especially the extrusion end should be decelerated to prevent turbulence from getting involved in the surface impurities.
　　对生产的各个阶段进行清理;
　　Clean up all stages of production;

　　2. 设备设备调整
　　2. Equipment adjustment
　　如果挤压棒不在中间，挤压棒运动磨损材料胆囊，会造成材料胆囊腹部变形等缺陷;模座中心，上、下、左、右向中心，严禁移动模座进行生产，上下错误，要联系机修进行维护;压实饼的大小应定期检测和更换。压实后的卷边饼也会产生发黑、夹渣等报废现象。材料胆囊使用很长一段时间,如出现变形,也会导致批量报废,报废生产很多,需要注意,新材料胆囊必须清除污垢的膀胱和膀胱抛光机安装之前。
　　If the extrusion bar is not in the middle, the movement of the extrusion bar will wear the gallbladder of the material, which will cause the abdominal deformation of the gallbladder of the material and other defects; the center of the mold base, up, down, left and right, is strictly prohibited to move the mold base for production, and the up and down errors should be contacted with the machine for maintenance; the size of the compaction cake should be regularly inspected and replaced. After compaction, the curling cake will also produce blackening, slag inclusion and other scrap phenomena. Material gallbladder used for a long time, if there is deformation, it will also lead to batch scrapping, scrapping a lot of production, it needs to be noted that the new material gallbladder must be cleaned of dirt before the installation of bladder and bladder polishing machine.
　　3.调整模具设计和生产计划
　　3. Adjust mold design and production plan
　　对于平面模具，如有必要，应安装导流板进行导流，以缩小进料口，夹紧死区。材料孔必须完全被模具分流孔包围，对每一套模具进行监控比较，如分流孔太大的现象，不能在机器上生产，要转到机器上生产。
　　For flat die, if necessary, guide plate shall be installed to guide the flow, so as to reduce the feed port and clamp the dead zone. The material hole must be completely surrounded by the mold shunting hole, and each set of mold shall be monitored and compared. If the shunting hole is too large to be produced on the machine, it shall be transferred to the machine for production.
