TECHNICAL FIELD

[0001] The utility model relates to metallurgy continuous casting technical field, concretely is a kind of bar round steel production surface anti-scratching transfer device. BACKGROUND

[0002] In hot-rolled bar production, the proportion of high-quality steel round steel is higher and higher, and there are high requirements for the surface of round steel in finished product application. Many products need to go through surface quality flaw detection inspection before leaving the factory. In the rolling process, in addition to the influence of rolling mill and guide device on the surface of steel, the steel parts need to pass through various specifications of guide groove when passing through the rack and water tank. The transition channel is adopted at the bottom of the channel in the form of conveying roller to solve the friction problem between the steel and the bottom of the channel. For the two sides of the channel, vertical roller is used to solve the friction problem. The bottom of the channel and the guide groove are basically in the form of active roller, and the rolling body on both sides is arranged in vertical mode. The contact between the steel and the vertical roller on both sides is not always maintained. When the contact force is small, the rolling body often cannot be driven to rotate.
