轧制钢

The effect of rolling processes on microstructure and properties of non quenched and tempered steels for oil well tube with various composition was studied.

研究了轧制工艺对不同成分的非调质油井管钢组织与性能的影响，并分析了不同组织对韧性的影响。

In general, the working pressure of steam is not more than 0.8 Mpa and the temperature of air will be below 150℃. The wing radiator consists of three rows of paratactic screw wing pipe mainly. The paratactic screw wing pipe is made through winding 05*10mm of steel belt onto 18mm steel pipe and then zinc hot galvanized. It can also be made with full stainless steel pipe and belt. Model SRL radiator is made of steel pipe and aluminum belt through rolling. Its radiation area in unit length is more than Model SRZ.

翅片式散热器主要由空气流向间的三排并列螺旋翅片管束组成，SRZ型散热翅片管束的加工工艺是反0.5*10毫米的钢带用机械绕片方法，绕在18毫米无缝钢管上，然后进行热镀锌，也可用不锈钢管及不锈钢带制成全不锈钢散热器，SRL型散热器则是用钢管和铝带轧制的翅片散热器，其单位长度的散热面积比SRZ型的更大。

The residual stress and deformation of the piece as well as the influences of tension on the crown and screw-down were analyzed by using the models. The comparison of simulation results and experimental data prove that the FEM models are accurate and reliable.

利用所建立的模型对带钢轧制过程轧件的残余应力、变形以及张力对板凸度和压下量的影响进行了模拟分析，模拟结果与实验结果的比较证明所建立的模型是正确的。

Based on rolling technology of 2050 hot strip roughing mill group, a 3-D coupling thermal, mechanical and microstructural rigid-plastic finite element model had been developed by using nonlinear finite element method and physical metallurgy microstructural evolution models.

根据某厂2050热带钢粗轧机组轧制工艺，借助物理冶金组织演变模型，利用非线性有限元法开发了热连轧过程热、力、组织耦合三维刚塑性有限元模型。

The rolling experiments were performed in the rolling mill of laboratory with lead, the roll pass scale is 1:5 according to the actual size of 310 Z shape steel. The effect of rolling design and the reduction to the molding of the 310 Z shape is the topic of the research works. We can conclude that the

本文针对孔型系统，将孔型缩小为实际尺寸的1/5，利用实验轧机轧制铅试样的实验方法，研究了孔型形状参数、道次压下量等因素对310乙字钢成型的影响，为改变孔型系统、提高产品质量提供了解决的方向。

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。
