Description

Technical Field

[0002] Round steel refers to solid steel with a circular cross-section, which is usually used in the production of mechanical parts. In order to ensure that the round steel can be used normally for a long time in special application conditions and environments, the round steel needs to be surface strengthened.

[0003] The existing round steel surface processing technology includes loading, heating, strengthening and other processes. The round steel needs to be transported to the heating chamber through a conveyor system. When the round steel is heated to the temperature required for surface strengthening, the round steel is shot peened according to different usage conditions and environments to strengthen the surface of the round steel.

[0004] For the existing round steel surface strengthening treatment device, after the conveying system transports the round steel to the heating chamber, the round steel needs to be heated by the heat generated by the combustion of gas and fuel. During this process, the bottom of the round steel is not easily heated, resulting in a temperature difference between the top and bottom of the round steel as a whole, which is prone to uneven residual stress distribution after strengthening treatment. In addition, for the existing round steel surface strengthening treatment device, waste gas is easily generated during the process of heating the round steel. This part of the waste gas will be directly filtered and treated, but the residual heat of this part of the waste gas cannot be reused. Therefore, a new round steel surface strengthening treatment device is proposed to solve the above problems. Utility Model Content
