轧制技术的有关问题:

般在板边缘较薄，扎或纵厚度偏差就叫做板凸度。如果板凸度足够大，450rolling mill，板厚偏差可以达到一定值，以至于钢板不适用于在严格要求板厚精度的场合。当厚度偏差增大（在板宽方向上厚度不同）导致在材料设计后产品损失中应考虑增加板厚边缘。

It is thinner on the edge of the plate， and the deviation of the ligation or longitudinal thickness is called the plate convexity. If the plate convexity is large enough， the thickness deviation of the plate can be reached to a certain value so that the steel plate is not suitable for the situation where the thickness of the plate is strictly required. When the thickness deviation increases (the thickness is different in the width of the plate)， the thickness edge of the plate should be added to the loss of the product after the material is designed.

闭口式机架为一整体铸件制成。这种机架形式在型钢车间中小型轧机上应用较多。其优点是强度和刚度较高，辊跳值较小，320rolling mill，产品精度较高。其主要缺点是制造比较困难，装卸、换辊不方便。轧制压力较大、对轧件尺寸要求比较严格时常采用闭口式机架。如初轧机、型钢连轧机和型钢成品轧机等。

The closed frame is made of a whole castings. This type of frame is used more in the ***all and medium mill in the steel workshop. Its advantages are that the strength and stiffness are high，220rolling mill， the roll jump value is ***all and the precision of the product is high. Its main disadvantage is that it is difficult to manufacture， and it is inconvenient to load and load and change the roll. When the rolling pressure is larger and the requirements for the size of the rolled piece are strict，鞍山rolling mill， the closed frame is often used. Such as the early rolling mill， the type steel continuous rolling mill and the steel finished rolling mill， etc.

连续加热炉连续加热炉包括推钢式加热炉、步进式炉、转底式炉、分室式炉等连续加热炉，但习惯上常指推钢式炉。连续加热炉多数用于轧制前加热金属料坯，少数用于锻造和热处理。

It is named according to the varieties of rolling， the type of rolling mill and the nominal size. The principle of 'nominal size'

For rolling mills， they are named after the gear ring and the pitch diameter of the herringbone gear.
