横轧是容器板轧机生产技术的特点之一。横轧的目的，一是展宽，当原料宽度不足于板宽时，采用展宽方式以达到板宽的要求；二是减少钢板纵横向性能差。这种特殊的轧制方式，促使轧机迟迟未能走向自动化，直至今日容器板轧机自动化过程中横轧仍然是一个关键的环节。
Rolling is one of the characteristics of container plate mill production technology. Cross rolling, the purpose of it is broadening, when raw material width is insufficient in the plate width, adopts the way of broadening plate in order to achieve wide requirements; The second is to reduce steel plate freely to the poor performance. This special way of rolling, rolling mill's delayed toward automation, until today container rolling mill automation process is still a key link.
　　容器板轧制通常在一个机架或两个机架上实行多道次往复轧制，原料除板坯以外，有时尚用大小钢锭、锻制坯与二次坯，规格非常繁杂，成品板规格和钢号也很多，即使原料尺寸与成品尺寸相近，但由于钢种的不同，轧制规程仍有很大的差异，给轧机自动化带来一定难度。
Container plate rolling are usually in a frame or two rack has multichannel reciprocating rolling, raw materials, except the slab has a fashion with the size of the steel ingot, the forging blocking and secondary billet, specification is very complex, product specifications and steel grade is very much also, even if the raw material size close to finished size, but because of the different steel grade, rolling schedule still has great difference, bring certain difficulty mill automation.
　　板型控制除横向与纵向以外，尚有平面板型的控制，再加上立辊轧边，更增加轧机自动化的难度。
Plate shape control in addition to the horizontal and vertical, there are flat plate type control, coupled with the vertical roll rolling edge, increased the difficulty of the mill automation.

　　控轧控冷是容器板轧机的一项特长，因容器板轧机具有随意变换道次和轧制温度的灵活性，并采取一些待温等轧的有效措施，有目的地控制道次压下率与等轧终轧温度，使轧机自动化添加了许多不稳定的因素。
Controlled rolling cold container plate mill is a special skill, because of the container plate mill with different time and the flexibility of the rolling temperature, and take some stay warm rolling of effective measures, such as purposefully control rate under time pressure and rolling finishing temperature, make the mill automation adds many unstable factors.
　　虽然采用控轧控冷技术，使线外热处理量明显减少，但容器板线外热处理仍然是一项必不可少的繁重工序。热处理种类有正火、回火、淬火、退火、调质及缓冷等方式，而炉型有连续式和间歇式之分，非常繁多。这些工序周期长，连续性差，要实现自动化自然会受到一定的影响。
While using controlled rolling technology of controlled cooling, make the line external heat capacity decreased significantly, but outside the container plate line heat treatment is still a necessary process. Heat treatment types with normalizing, tempering, quenching, annealing, tempering and slow cooling way, while type furnace is continuous or intermittent, very wide. The process cycle is long, poor continuity, in order to realize automation of natural will be affected by certain influence.
