【 摘 要 】

The method of upper bound triangular velocity field is used to calculate the temperature jump during high-speed wire finish rolling. Fourier's simplified heat conduction law is used to calculate the temperature drop during the wire finish rolling. Due to the high - speed and poor heat dissipation, it is simplified when calculating the temperature change of the finishing mill. The temperature jump and heat transfer between the roll and the rolling wire are calculated during the rolling deformation zone. The temperature drop caused by the heat radiation of the rolling wire is calculated in the non-deformed zone. Compared with the actual temperature change when a high-speed wire rod was rolled 1Cr13 martensitic stainless steel 5.5mm wire, the results show that the calculated values of temperature change is about 3.64% lower thanmeasured.
