4) breakdown roll
开坯轧辊
1.
The groove of Φ550 breakdown roll is overlaid to raise its hardness and wearability, prolong its working life and consequently the quality of products gets improved, operation ratio raised by 6 percent.
针对唐山国丰钢铁有限公司第三轧钢厂Φ550车间热轧窄带钢时,Φ550mm开坯轧辊使用寿命短、轧槽磨损严重等问题,对开坯轧辊轧槽实施了表层堆焊,增强了轧辊硬度和耐磨性能,延长了换辊周期及轧辊的使用寿命,提高了产品质量并使轧机的作业率提高了6%。
5) initial rolling temperature
开轧温度
1.
The rolling results and performance analysis showed that the initial rolling temperature should be controlled from 1 100 ℃ to 1 180 ℃, If the temperature is higher than 1180 ℃, the rolled piece will be difficult to be bitted;if the temperature is below 1 100 ℃, the steel tend to thermal crisp and the head of rolled piece is easy to crack.
轧制结果及性能分析表明,开轧温度控制在1100～1180℃范围内较好,高于此温度范围轧制时会出现轧件打滑,咬入困难现象,温度低于此范围,钢容易发生热脆,轧件头部易开裂。
6) rolling-cogging
轧制开坯
1.
It is pointed out that PM(powder metallurgy) has become the main process for producing tungsten billets on an industrial scale, rolling-cogging plays a great role in cogging PM tungsten billets, and the downstream fabrication takes the main action as transferring tungsten sheets to components, parts, even devices.
粉冶法已成为工业规模生产钨锭的主要方法;轧制开坯成为粉冶法钨锭的主要开坯工艺;深加工技术是把板材转变成元件、部件,甚至是设备的关键技术。
补充资料：环状碳酸酯低聚物开环聚合
分子式：
CAS号：
性质：简称开环聚合聚碳酸酯。系新近发展起来的合成超高分子量聚碳酸酯新工艺。它是先由双酚A与光气界面缩聚成双酚氯甲酸酯，再催化闭环成链节数n≈5～20的环状碳酸酯齐聚物，然后在催化剂存在下开环聚合，制得超高分子量线型聚碳酸酯(n≈50～1000)。可用以制得高强度薄膜或形状极为复杂的高性能模塑制品。且加工成型性好。也可用于制作高性能复合材料。
