What is a rolling medium frequency heating furnace
The purpose of heating in the medium frequency heating furnace is to heat the round steel to be rolled to a uniform and suitable temperature for rolling. The heating temperature for conventional rolling is 1200°C. This heating method is often used in rolling, roll forging and cross rolling, and has become a consensus in the industry.
The heating speed of the rolling medium frequency heating furnace is very fast and the temperature is uniform, which is very suitable for the requirements of the rolling mill.
