The laminar cooling system has synthetic complexities such as highly nonlinear, variations of operating conditions and the difficulty of measuring the strip temperature online.
层流冷却系统具有强非线性、工况变化频繁、带钢温度不能连续测量等综合复杂性。
For the model of laminar cooling control of hot rolled strip, the accuracy of coiling temperature control is unsatisfactory because the heat transfer in the strip itself is ignored.
在热轧带钢层流冷却控制数学模型中，由于忽略带钢内部的热传导而使卷取温度控制精度不良。
The results indicate that the holes of X70 pipeline steel result from pitting corrosion. And the appearance of the pitting corrosion is because of high concentration of Cl - in laminar-cooling water.
实验结果表明，X70管线钢凹坑是由于点蚀腐蚀所引起，而点蚀产生的原因是由于层流冷却水中的氯离子浓度偏高。
