轧钢生产的工序十分复杂，尽管随着轧制质量要求的提高，品种范围的扩大以及新技术，新设备的应用，组成工艺过程的各个工序都会有相应的变化.
The process of rolling production is very complicated. Although all the processes of the process will be changed along with the improvement of rolling quality requirements, the expansion of varieties and the application of new technology and new equipment.
***轧钢生产工艺过程首先是为了合格的，即合乎质量要求或技术要求的产品，并且要在保证产品质量基础上努力提高产量。这一任务的完成不仅取决于生产过程的合理性，而且取决于时间和设备的充分利用程度。
The process of rolling steel production is first made for qualified products, which are suitable for quality requirements or technical requirements, and we must strive to increase output on the basis of ensuring product quality. The completion of this task depends not only on the rationality of the production process, but also on the full utilization of the time and the equipment.
轧钢原料：
目前主要为连铸坯，另外还有钢锭，段轧钢等，正确的选择坯料的种类，断面形状和尺寸大小以及重量对轧钢生产具有重要意义。
Rolling material:
At present, mainly for continuous casting billets, as well as steel ingots, section rolling, etc., correctly choose the type of billet, section shape and size and weight are important for steel rolling production.
因为四列的短圆柱轴承在外圈上是可以脱落的，所以，也可以将内圈之间安装于轧辊在辊颈上，并将外圈安装在轴承座的内部。 我们从轧钢机整个装配的过程来看，轧钢机中轴承以及轴承座在受力的情况上都是比较良好的.
Because the four columns of short cylindrical bearings can be shedding in the outer ring, the inner ring can also be installed between the roller and the roll neck, and the outer ring is installed inside the bearing seat. In terms of the whole assembly process of rolling mills, the bearings and bearing housings in rolling mills are relatively good in force.
