Description

Technical Field

[0001] The utility model relates to the technical field of round steel production, in particular to a heating furnace for round steel production. Background Art

[0002] Round steel refers to solid long strips of steel with a circular cross-section. Its diameter ranges from a few millimeters to several hundred millimeters. The production process of round steel mainly includes steelmaking, rolling, heat treatment and other steps. Round steel heating is an important link in the metal processing and heat treatment process. Its main purpose is to improve the plasticity and toughness of round steel and create favorable conditions for subsequent processing and forming. A heating furnace is required for round steel production heating.

[0003] In the prior art, a heating furnace is usually composed of a control system, an auxiliary system, and a heating system. The induction heating furnace generates Joule heat inside the round steel through high-frequency induction current to achieve heating. When high-frequency current passes through the induction coil, a changing magnetic field is generated inside the round steel, thereby inducing eddy currents inside the round steel. When these eddy currents flow inside the round steel, heat is generated due to the presence of resistance, causing the round steel to heat up.

[0004] However, the operator needs to manually adjust the position and angle of the round steel, push one end of the round steel into the middle of the coil in the heating furnace, and use a clamp to fix and limit the round steel at the other end to prevent the round steel from slipping and rolling, which increases the complexity and workload of manual operation and reduces production efficiency. In addition, during the heating process, the round steel contacts the wall of the heating coil, the round steel is not in the center of the heating coil, and the spacing between the side wall of the round steel and the coil is inconsistent, resulting in uneven heating of the round steel, affecting the heating effect of the device.
