Argon is a ladle furnace or ladle handling of a number of ways that it can homogeneous liquid steel temperature, composition, Removing part of mixed gases and thereby improve the quality of steel. 钢包吹氩是炉外处理或钢包精炼许多方法中的一种,它可以均匀钢液温度,成分,脱除一部分气体与夹杂从而改善钢材质量。
The behavior of penetration resistance of the functionally graded armour in which the particles distribute continuously is better than that of homogeneous steel plate; 畜此工业大学硕士研究生学位论丈(6)增强颗粒连续分布的功能梯度装甲板比匀质钢板表现出良好的抗侵彻性能;
Inside-cooling apparatus can improve the billet quality due to relief the flow velocity and more homogeneous flow of liquid steel. 内冷却器对钢液的流动影响很大,可以减缓钢液的流动速度,减少冲击深度,并能使钢液的流动更加均匀,提高铸坯质量。
Taking the advantage of the principle that the propagation velocity of ultrasonic wave stays constant in homogeneous medium, research was carried out to detect the density of steel tube concrete by ultrasonic wave method. 利用超声波在均匀介质中传播的速度为常数的原理,进行超声波法检测钢管混凝土密实性的研究。
In this paper for reinforcing circular concrete slabs, instead of homogeneous ones commonly used, a nonhomogeneous two-way steel net is proposed, due to which there is a saving of 12~ 22% in reinforcing steel. 本文建议在混凝土圆板设计中以中密方格钢筋网代替常用的均匀方格钢筋网,可收到节省钢材12~22%的效果。
Homogeneous compression tests were carried out in a cam plastometer on mild steel, 13% chromium steel, aluminium and lead. 在凸轮形变机上进行了G3、1Crl3钢、铝及铅的恒应变率均匀压缩试验。
This technology realizes integral tension and relaxation to ensure the homogeneous deformation of steel cable, so that the construction speed is enhanced and the quality of beam end is ensured. 阐述了桥梁板的施工工艺,该工艺实现了整体张拉、整体放张,使钢绞线逐根受力均匀,施工速度快,能保证梁端的质量。
The results showed that the surfaces of the coatings are homogeneous, polished and with strong corrosion resistance which is superior to A3 steel specimen, nickel-phosphorus coating and phosphating film. 结果表明:在最佳施镀条件下,可得光亮、致密、耐腐蚀性强于A3钢、磷化膜及Ni-P镀层的纳米复合化学镀层。
Although many machine parts require good surface wear resistance and good internal toughness, homogeneous wear resistant material by adding strengthening phase alloy elements to high manganese steel has higher hardness and less toughness at the same time. 实际应用中,许多机器零(部)件要求材料表面耐磨而内部具有良好韧性,如果单纯在高锰钢中加入强化相合金元素制成均质耐磨材料,在提高材料硬度的同时往往会降低材料的韧性。
