gb8163无缝管

通过计算得出：转炉冶炼过程前期是去除钢中钛的有利阶段。在转炉冶炼后期，由于钢液温度升高，钢液脱钛所需的氧活度明显增加；实际生产中采用转炉双渣法冶炼，将转炉终点碳质量分数控制在0.50％～0.65％，钢液温度控制在1635～1670℃，氧活度控制在0.010％左右，就可以达到控制转炉冶炼终点ｗ(Ti)0.0010％的目标。通过采用转炉双渣法冶炼、适当提高转炉冶炼终点碳含量，可以达到降低钢中钛含量和避免钢液氧化严重、减轻转炉炉后操作负担的双重目的。

另外留一节管一端法兰不固定，待现场安装时按现场实际尺寸调整。风管安装现场的材料、半成品按编的顺序和不同系统，水平运输用自制的双轮小车，垂直运输用电梯，运输中注意成品保护。检查现场预留孔洞的位置、尺寸符合图纸要求否，有无遗漏现象，预留孔洞应比风管截面每边尺寸大1毫米将风管和部件按编号组对，复核无误后即可连接和安装。连接长度根据风管的壁厚、法兰与风管的连接方法、安装结构部位、吊装等因素，但尽量在地面上进行连接，一般可接至1-12米长左右，但不准将可拆卸的接口，装在楼板或墙体内。

GH4169合金是目前使用量的沉淀强化镍基高温合金，主要用于航天发动机涡及导向叶片和地面燃气轮机的制造。Nb为其中强化的主要合金元素。在优质GH4169合金中，Nb元素质量分数为4.75%～5.5%。Nb元素既对合金的强化起到关键作用，同时又成为合金主要的偏析元素。Nb元素的偏析会在枝晶间产生各种析出相，微观偏析到一定程度就会产生宏观偏析，如黑斑等缺陷使钢锭报废。
