This contact risks causing premature wear of the pipe due to chafing, which long term could lead to a leakage of coolantfluid.
这种接触会造成早期的出水管老化,长时间会导致冷却液的泄漏。
2
It is usually difficulty to obtain film coefficients between the working roll and the coolantfluid as we solve the temperature field of the roll.
工作辊与冷却液之间对流换热系数的确定是轧辊温度场分析的难点。
3
Temperature in a very long period of time to maintain the owner must check the coolant level is normal, if you find that the level of the cooling fluid is below the line, should be added in time.
