The high quality, unoxidized plate ingots are manufactured. Diffusion/rolling welding composite processing is designed to coat the Al-Li ingots. The thickness of coating layers can be controlled accurately between 0.05-0.10mm.

使用楔形块轧制方法，评价了均化处理和在轧制温度对Al-Li合金铸锭临界塑性变形压下量D的影响，结果指出，可根据材料强度要求选择C制度均化，Al-Li合金都显示出有优良的热轧塑性，D值在50-60%。

The bulging of ingot with a liguid core during rolling is the plastic bending of its solidified shell as a result of a liguid core pressure and a rolling pressure on ingot,which is one of the main deformation characters of the rolling in an unsolidified state.

液芯钢锭轧制过程中产生鼓肚，是由于在液芯内压力和轧制压力的作用下，钢锭凝固壳产生塑性弯曲变形的结果，它是液芯钢锭最主要的变形特点。

In order to meet the need of economic development for large-specification roll of steel plates, technical improvements have been carried out in the hot-rolling mill. The six sets of high pressure water pump, which cannot provide high enough speed of water supply for rolling, is replaced using three sets of high pressure centrifugal pump. The working mode of three sets of high pressure centrifugal pumps is that two pumps work and another one is spare. After the project has been carried out other problems emerge, for example, the electromotor becoming very heat and the pump being frequently attainted.

为了适应经济发展对轧制大规格的热轧板卷的需要，热轧板厂对轧线进行了技改，将6台不能满足快节奏高速轧制供水的高压柱塞泵更换为3台高压离心泵，三台高压水泵采取两用一备工作状态，投运以来，又出现电机严重发热，泵频繁损坏的问题。

We understand how the steel deforms in various type of grooves and in various rolling conditions steel grade, temperature, rolling speed, etc.

我们理解钢如何在各种孔型和各种轧制条件（钢种，温度，轧制速度等）下进行变形。

Moreover, it is necessary to point out an additional advantage: the strip obtained at the end of the passage throughout the whole hot-rolling and casting line is already at its final thickness and ready to be used, without the need to carry out an additional treatment in a cold-rolling line.

此外，需要指出一个额外的优点：贯穿整个热轧制和铸造线的末端获得的金属条已经是具有最终厚度并准备进行使用，而不需要在冷轧制线上进行附加的处理。

On the basis of experiments, a mechanical model of cold-rolled steel matrix composites is established and a corresponding calculating equation is deduced.

Minitype rolling mill exploitation has gone to the lavatory for the experiment and scientific research have provided quite a few , the improvement the main body of a book has been carried out on present use rolling mill of precise copper of our university laboratory, has adopt gear wheel deflection falling-in way to have realized rolling mill controlling to rolling thickness , the rolling mill improving the day afer tomorrow has adopt three set of gear wheels to be engaged , two set of gear wheels axes among them may slide respectively along the erect sliding rail and the arc sliding rail , come true thereby to controlling rolling thickness.

小型轧机的开发为实验和科研提供了不少方便，本文对我校精密铜实验室现用轧机进行了改进，采用了齿轮变位啮合办法实现了轧机对轧制厚度的控制，改进后的轧机采用三组齿轮啮合，其中两组齿轮的轴线可分别沿竖直滑轨和弧形滑轨滑动，从而实现对轧制厚度的控制。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
