Description

Technical Field

[0001] The present invention belongs to the technical field of metallurgical industrial production equipment, and relates to the production technology of rolling round steel billets. More specifically, the present invention relates to a safe and flexible cold descaling box. Background Art

[0002] Since the requirements for the contact surface between the pad and the billet when rolling round billets are higher than those for rolling square billets, controlling the amount of iron oxide scale attached to the surface of the round billet before the billet enters the furnace will affect the surface quality of the round billet during the heating process.

[0003] In the prior art, a fixed cold descaling plate is installed on the steel roller, which is fixed to the steel structure foundation of the steel roller by anchor bolts. A steel wire rope is clamped between the descaling plate and the pressure ring as a wire brush to remove the iron oxide scale on the surface of the round billet. The steel wire rope needs to be adjusted manually after it fails in use. The adjustment method is to stop the roller, loosen the pressure plate of the cold descaling ring, adjust the length of the steel wire rope, and then use a wrench to adjust the pressure plate bolts, and tighten the pressure plate after it reaches the appropriate position.

[0004] The specific operating principle of the on-site operation is that the pressure plate fixes the position of the wire rope. If the pressure plate is disassembled too loose, the wire rope will fall off due to gravity; if it is not disassembled loose, the adjustment force of the wire rope is difficult to control, so each adjustment of the wire rope will consume more manpower and time. At least 2 people are required to handle it for 30 minutes each time. Each adjustment will take up some time. More adjustments mean more hidden dangers in the operation, which also creates a certain work intensity for employees. Summary of the invention

[0005] The invention provides a cold descaling box for rolling round steel billets, which aims to utilize movable descaling plates to safely and flexibly adjust the number of descaling plates for cold descaling.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] The cold descaling box for rolling round steel billets of the present invention comprises a descaling plate and a pressure ring, wherein the pressure ring presses a steel wire rope onto the descaling plate; the cold descaling box is fixed on a steel structure foundation of a steel loading roller table; the cold descaling box is provided with a plurality of parallel plate grooves, wherein the descaling plates are inserted into the plate grooves, and a descaling plate is inserted into each of the plate grooves.

[0008] The cold descaling box is provided with four plate slots; 1 to 4 descaling plates are installed in the four plate slots.

[0009] The center height of the cold descaling box is the center of the round steel billet.

[0010] Both sides of the lower insertion end of the descaling plate are provided with guiding slopes.

[0011] The cold descaling box is also provided with a plurality of spare descaling plates.

[0012] The thickness of the descaling plate is 30 mm.

[0013] The thickness of the pressure ring is 16 mm.

[0014] The number of the descaling plates is greater than the number of the plate slots, and the extra descaling plates are used to replace spare parts of the descaling plates.

[0015] A through hole for lifting is respectively arranged on both sides above the descaling plate.

[0016] The present invention adopts the above technical solution, and spare parts can be adjusted in advance under normal production conditions, which also reduces the adjustment time; while reducing the labor intensity of employees, it effectively reduces the time affected by online adjustment and improves the safety factor of employees' operations.

[0026] The specific implementation modes of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0027] like Figures 1 to 7 The structure of the present invention is a cold descaling box for rolling round steel billets with safe and flexible performance, including a descaling plate 1 and a pressure ring 2; Figure 5 As shown, the pressure ring 2 presses the steel wire rope 4 onto the descaling plate 1. It is tightened by 8 fastening bolts.

[0028] In order to solve the problems existing in the prior art and overcome its defects, and to realize the invention purpose of using movable descaling plates, safely and flexibly adjusting the number of descaling plates, and performing cold descaling, the technical solution adopted by the present invention is:

[0029] like Figures 1 to 7 As shown, the cold descaling box for rolling round steel billets of the present invention, the cold descaling box 5 is fixed on the steel structure foundation of the steel loading roller; the cold descaling box 5 is provided with a plurality of parallel plate grooves, the descaling plates 1 are inserted into the plate grooves 3, and each of the plate grooves 3 is inserted with a descaling plate 1.

[0030] The present invention fixes the cold descaling box 5 on the steel structure foundation of the steel roller, and takes advantage of the easy disassembly of the descaling plate 1 to pre-adjust the steel wire rope 4. Moreover, when adjusting offline, the descaling plate 1 is laid down, and the steel wire rope 4 will not be out of control due to gravity, which greatly shortens the adjustment time. While reducing the labor intensity of the operator, it effectively reduces the time affected by the online adjustment and improves the safety factor of the operator's operation.

[0031] The cold descaling box 5 is provided with four plate slots; 1 to 4 descaling plates 1 are installed in the four plate slots.
