Problems solved by technology

During the coiling process of the hot coil box, under the action of the bending roller, the oxides on the surface of the high-temperature billet will peel off in large quantities along the tangential direction of the steel coil, and a large number of fine iron oxide scales will float upward and on both sides under the action of high temperature, and finally fall In the factory building, iron oxide scales are everywhere on the site, and the environment is harsh
The hot coil box has a compact structure and many moving parts. The design and installation position of the dust removal device are limited, and it cannot affect the temperature of the steel coil. Therefore, the hot coil box currently used at home and abroad does not use a dust removal device.

Embodiment

[0019] Such as figure 1 As shown, a hot coil box water mist dust suppression device includes a hot coil box frame, a bending roller assembly, a hydraulic system, an angle change system and a low-pressure water system.

[0020] The bending roller assembly includes a lower bending roller 3 and two upper bending rollers 6 . The two upper bending rollers 6 are installed on the frame 10, the lower bending roller 3 is fixed, and the two upper bending rollers 6 and the lower bending roller 3 form an arc-shaped roll gap; the blind end trunnion of the oil cylinder 2 is fixed, and the lug of the rod cavity The shaft is connected to the frame 10 through a pin shaft. The frame 10 moves within a certain range around the rotating shaft 11 under the thrust of the oil cylinder 2, and the body of the oil cylinder 2 will swing around the blind end trunnion.

[0021] Such as figure 2 As shown, the hydraulic system includes sequentially connected hydraulic control check valves 101 and 103, a ...

Abstract

The invention relates to a hot coil box dust suppression and removal device, and belongs to the technical field of environment-friendly mechanical equipment. The hot coil box comprises a hot coil boxframe, a bending roller assembly, a hydraulic system, an angle changing system and a low-pressure water system. The angle of dust removal water can be automatically changed along with the increase ofa steel coil, the influence of water mist on the temperature of the steel coil is avoided, the dust removal effect is guaranteed, the problems that oxide particles spread everywhere and pollute the environment during coiling work of a hot coil box are solved, and the device is simple in structure and convenient to manufacture, install and maintain.

Description

technical field [0001] The invention relates to a dust suppression and dust removal device for a hot coil box, belonging to the technical field of environmental protection machinery and equipment. Background technique [0002] The function of the hot coil box is to intermediately coil the rough rolled straight billet into a cylindrical shape, and then reversely uncoil it into the finish rolling unit. Since the intermediate billet is kept warm in the hot coil box and the direction of the head and tail of the intermediate billet is changed when it enters the finishing rolling unit, the "difficulty" of hot strip rolling with a large temperature difference between the head and tail of the intermediate billet is solved; The box is equipped with two stations (coiling station and uncoiling station) which can work at the same time to improve the working efficiency of the hot coil box. During the coiling process of the hot coil box, under the action of the bending roller, the oxides...
