一、引言ф650×1600mm铝板连续铸轧机可将700℃左右高温的铝液连续地铸轧出约7mm厚的铝板。该铸轧机组由铸轧机、牵引机、液压剪切机、五辊张力机及卷取机等组成,全长约8000mm。铸轧机的铸轧速度约为1m/min,这就是说,由铸轧机轧出的铝板大约经过8分钟左右的时间便到达卷取机,这时铝板的温度还在300℃以上,这就使卷取机的卷筒处于热卷取工作状态,因此,要求卷取机的卷筒在300℃左右的高温时应具有良好的使用性能,这样,才能保证卷取机卷筒在连续卷取工作状态下的
First, the introduction ф650 × 1600mm aluminum continuous casting mill can be about 700 ℃ high temperature molten aluminum continuously cast about 7mm thick aluminum. The casting unit consists of casting mill, traction machine, hydraulic shearing machine, five-roll tensioning machine and coiler and other components, a total length of about 8000mm. The casting speed of the casting mill is about 1 m / min, which means that the aluminum plate rolled out by the casting mill reaches the coiler in about 8 minutes, and the temperature of the aluminum plate is still above 300 ° C. Coiler winder in the hot coiling state, therefore, requires coiler reel at about 300 ℃ high temperature should have good performance, so as to ensure that the coiler reeling in the continuous work State of
