1. Forged medium frequency heating furnace adopts 500kW/1000Hz intermediate frequency power supply, the inner diameter of the inductor is 180mm, and the guide rail made of 1Crl8Ni9Ti austenitic heat-resistant steel bar is installed at the bottom of the heating furnace. When the Φ102mm×13mm steel pipe is locally heated, the inner hole of the inductor and the inner core of the steel pipe cannot overlap, and the upper part of the steel pipe is far from the induction coil, resulting in uneven heating temperature.
2. Solution
The method of rotating the steel pipe into the feed, while heating, the steel pipe rotates. It is necessary to make a rotating device and install it in the furnace mouth of the heating furnace, which solves the problem of inconsistency in the height of the steel pipe. The rotating device is composed of an armrest, a moving trolley, a base bracket and a locator component. Rotate evenly. Heat evenly. The successful application of the equipment greatly reduces the labor intensity of workers and solves the problem of uneven temperature of the locally heated steel pipe.
