The bar tail brake is a device for controlling the speed of a finished product before the finished product is loaded on a cooling bed in the steel rolling production process. Taking an HTC (high-speed double-channel conveying system) of Daneli company as an example, a bar after finish rolling is sent to a cooling bed at a high speed, the speed of the bar conveyed to the cooling bed is as high as 50m/s, a tail brake is arranged on the incoming material side of an inlet of the cooling bed to brake the bar, the speed of the bar is reduced to a certain set speed value, the free sliding distance of a rolled piece is greatly reduced, and the bar is matched with a bidirectional collecting tank for use, so that the bar is alternately sent to the cooling bed by two lines, and the high-speed rolling is realized.
At present, the rod tail brake generally adopts a mechanism type that upper and lower brake rollers clamp a rod rolled piece, the lower brake roller is usually fixed, the upper brake roller is pressed down for clamping, and a typical tail brake is shown in fig. 1, and the structure of the typical tail brake mainly comprises a cylinder 1, a swing arm 2, an upper brake roller 3, a lower brake roller 4, a motor 5 and a frame 6. When a bar rolled piece passes through a tail brake, the air cylinder 1 drives the swing arm 2 to act, so that the upper brake roller 3 is pressed down, the lower brake roller 4 rotates at an accelerated speed and is driven by the bar rolled piece to rise the speed until the speed is the same as the linear speed of the upper brake roller and the lower brake roller, and then the motor 5 enters a power generation braking state to decelerate the bar and finally throws the bar out at a low speed.
Because the temperature of the rolled bar material exiting the rolling mill is high, if the brake roller on the tail brake is pressed down too tightly, the upper side and the lower side of the rolled bar material are deformed, indentation usually occurs, and the surface quality of the bar material product is influenced; if the upper brake roller is pressed loose, the speed of the rolled bar out of the tail brake is too high, the purpose of braking cannot be achieved, and mechanical and process accidents may even be caused.
