The applicable range of a set of hot continuous rolling mills is directly related to the economic benefits of the hot rolling production line. To adapt to the stability of the continuous rolling mill, higher requirements are put forward for the threading stability involved. And there are many factors affecting the threading efficiency. Among them, the coordination between the loading speed and the speed of the finishing mill is also extremely crucial. If the hot-rolled steel plate is loaded quickly and the finishing mill has no time to process it, there will be a dangerous situation of steel plate deformation, which will affect the finishing efficiency.

A hydraulic press 205 is welded to the outer side of the mounting groove cylinder 203. The telescopic end of the hydraulic press 205 is connected to a hydraulic slide bar 206. An activity groove is provided at a position corresponding to the hydraulic slide bar 206 on the outer side of the mounting groove cylinder 203. The hydraulic slide bar 206 is slidably connected to the mounting groove cylinder 203 through the activity groove, which facilitates feeding speed reduction;

[0032] A speed control groove 207 is provided on the inner side of the mounting groove cylinder 203. A fixed arc plate 208 is welded to the bottom end of the hydraulic slide bar 206. A fixed rod 209 is welded to the bottom end of the fixed arc plate 208. A speed reduction slider 210 is slidably clamped on the outer side of the fixed rod 209.

[0033] A feeding component 3 is installed on the inner side of the feeding support 1;

[0034] The feeding component 3 includes a sliding hole 301, a stable seat 302, a limiting slide bar 303, a load-bearing inclined rod 304, a positioning groove 305, and a positioning rod 306;

[0035] A sliding hole 301 is provided on the inner side of the feeding support 1. A stable seat 302 is provided on the side end face of the feeding support 1.

[0036] Working principle and usage process of the present utility model: First, the operator sleeved the steel coil on the outer side of the loading shaft 204. Subsequently, the operator inserted the steel strip into the internal part of the rolling mill, and then started the precision rolling of the steel strip. After starting the precision rolling, the hydraulic press 205 was turned on, and then the hydraulic slide rod 206 was pressed down. At this time, it could drive the fixed arc plate 208 to press towards the loading shaft 204, causing the deceleration slider 210 to squeeze the loading shaft 204, thereby applying a greater pressure on the loading shaft 204. At this time, even if the gravity and inertia of the steel coil on the outer side of the loading shaft 204 were large, the rotation speed of the loading shaft 204 could be reduced by the deceleration slider 210 during rotation to prevent the loading speed from being too fast. And after the weight of the steel coil decreased, the pressure on the loading shaft 204 could be reduced to ensure the rotation speed of the steel coil with a small weight, thereby accurately controlling the loading speed, preventing the precision rolling from failing due to the out-of-control loading speed, improving the precision rolling efficiency. And after using for a period of time, the deceleration slider 210 could be pulled out from the outer side of the fixed rod 209, and the worn deceleration slider 210 could be disassembled. Then, the new deceleration slider 210 was clamped on the outer side of the fixed rod 209 through the fixing hole 211 to further ensure the speed control efficiency;

[0037] Next, after the processing of a steel coil was completed, the positioning rod 306 could be pulled out from the inside of the positioning groove 305 to release the position limit of the loading support 1. Subsequently, the operator could slide the loading support 1 on the outer side of the limit slide rod 303. Then, the operator could pull out the loading shaft 204 from the inside of the bearing 202. Then, the operator could move the new steel coil to the horizontal position of the bearing 202 through the loading shaft 204. Subsequently, the two loading supports 1 were moved towards the loading shaft 204, and the loading support 1 was moved to the position of the positioning groove 305. Finally, the positioning rod 306 was inserted into the inside of the positioning groove 305 to fix the new steel coil, which was simple and convenient to replace the new steel coil and improved the steel coil replacement efficiency and further improved the precision rolling efficiency.
