[0056] Working principle: When the present invention is in use, first connect the natural gas pipeline 203 to an external gas pipeline. When heating is required, start the valve on the gas pipeline and the four rows of gas heating nozzles 202 to facilitate the automatic heating of the round steel in the support heating housing 101. Then start the two linear electric cylinders 401 to extend the output shafts of the two linear electric cylinders 401.

When the driving gear B 502 is meshed and connected with the left driving gear A 306, the left half of the high-temperature resistant support rods 304 rotate. When the driving gear B 502 is meshed and connected with the right driving gear A 306, the right half of the high-temperature resistant support rods 304 rotate, enabling the round steel to rotate automatically during heating, ensuring uniform heating of the round steel and improving the heating effect of the round steel. When the heated round steel is removed, the two arc-shaped pressing rods 308 at the position of the heated round steel can push the corresponding two rectangular force-bearing plates 605 upward, causing a row of rectangular pushing plates 603 to drive the heated round steel upward, which is beneficial for removing a row of heated round steel and also facilitates the placement of the round steel to be heated, making it more labor-saving when placing and removing the round steel. When the two arc-shaped pressing rods 308 are separated from the two rectangular force-bearing plates 605, a row of rectangular pushing plates 603 moves downward a certain distance to ensure that when the two arc-shaped pressing rods 308 contact the two rectangular force-bearing plates 605 again, the two arc-shaped pressing rods 308 can still push the corresponding two rectangular force-bearing plates 605 upward.
