【不知所云】
Blooms are sometimes further reduced in size to billets mills(Figure 9.8)before being processed into finished products such as bar and rod stock .
在被处理成块状、棒状坯这样的制成品之前,大钢坯有时还进一步缩小尺寸以适应钢坯处理设备.
Bar and rod (from which wire is made) can be made of either low-carbon steel or higher-carbon and alloy steel.
块状、棒状坯（钢丝就是由它们制造的）能被制成低碳钢或者高碳合金钢.
As the ingot is carried through the massive rolls the hot, plastic steel is squeezed to a smaller thickness .
当方坯通过大型轧制机,热的、可塑的钢被挤压得更薄.
The rolls are brought closer together on each pass, causing the ingot to get longer and thinner as it passes between the rolls (Figure9.9).
由于轧辊之间距离如此之近,当方坯经过轧辊之间时变得更长更薄.
Rolled shapes become quite long and must be cut to standard customer-length (Figure9.10).
轧制后的形状变得十分长,必须被剪成标准的定长.
Different configurations of the rolling mills include two-high, three-high , four-high, cluster mill, and tandem rolling mill.
不同构造的轧机包括二辊式,三辊式,四辊式,多辊式以及连轧式.
The two-high rolling mill can be used for reducing the stock by reverse action;
二辊式轧机通过往复动作缩减坯料.
however, because of the large inertia of the rolls it requires a complex mechanism for reversing direction of rotation.
然而,由于巨大的轧机惯性,它需要复杂的机械装置使转动方向可逆转.
The three-high rolling mill has the advantage over the two-high mill that the direction of rotation of rolls does not have to be reversed.
三辊式轧机相比二辊式的优点是轧机转动方向不必可逆.
In one pass, stock is passed between the top two rolls,
工作过程是这样的：坯料通过上面的两部轧机,
then the stock is lowered and passed between the lower two rolls, after which it is lifted and the operation is repeated (Figure9.9).
然后,坯料被降低位置通过更低的两部轧机,当它被再次升起,重复前面的操作.
The only disadvantage of this configuration is that it requires an expensive handling system.
这种构造唯一的不足是需要一种昂贵的传动系统.
Four-high(Figure9.9 and 9.11) and cluster mills (Figure9.9) use rolls of small diameter to reduce the dimension of the stock, since smaller-diameter rolls require less energy and force for the same effect…….
四辊式和多辊式使用更小直径的轧辊以减少坯料尺寸,因为更小直径的轧辊能耗更低.
