Description

Technical Field

[0001] The utility model relates to the technical field of beam steel rolling, in particular to a constant temperature beam steel rolling device capable of repeated rolling. Background Art

[0002] Steel rolling is the process of changing the shape of steel ingots and billets between rotating rollers. The purpose of steel rolling, like other press processes, is to obtain the desired shape, such as plate, strip, wire rod, and various sections; and to improve the internal quality of the steel. Common products such as automotive steel, bridge steel, boiler steel, pipeline steel, rebar, rebar, electrical silicon steel, galvanized sheet, tinplate, and even train wheels are all produced through the steel rolling process.

[0003] An existing Chinese utility model patent with reference publication number CN219483780U discloses a rolling apparatus comprising a wedge device and a rolling mechanism, the rolling mechanism comprising a first roller, a second roller, a first guide plate, and a second guide plate. The wedge device comprises a main frame, a dovetail wedge assembly, a connecting member, and a drive device. The dovetail wedge assembly comprises a first dovetail wedge, a second dovetail wedge, a third dovetail wedge, and a fourth dovetail wedge. The connecting member comprises a first connecting assembly, a second connecting assembly, a third connecting assembly, and a fourth connecting assembly. The drive device is configured to simultaneously drive at least one of the first dovetail wedge and the second dovetail wedge and at least one of the third dovetail wedge and the fourth dovetail wedge to move in a third direction, thereby causing at least one of the first roller and the second roller to move toward or away from the other, and at least one of the first guide plate and the second guide plate to move synchronously toward or away from the other. The rolling apparatus provided by the utility model achieves simultaneous adjustment of the roller spacing and the guide plate spacing.

[0004] Most existing rolling equipment has an open structure and cannot reduce the heat loss of the steel billet during rolling. After a period of rolling, the temperature of the steel billet decreases, which affects the shaping effect. In addition, the existing rolling equipment needs to transfer the steel billet to the front end of the rolling roller after the steel billet passes through the rolling roller, which is very inconvenient during repeated rolling.

[0015] Compared with the prior art, the present invention provides a constant temperature beam steel rolling device capable of repeated rolling, which has the following beneficial effects:

[0016] 1. The utility model sets up an insulation tube and an electric heating tube fixed inside the insulation tube to increase the temperature inside the insulation tube. In addition, the insulation tube can place the steel billet in a space with a low gas flow rate during the rolling process. The heat of the steel billet can only be transferred to the external air through the front and rear ends of the insulation tube. In this way, the speed of heat loss of the steel billet during the rolling process is reduced to avoid rapid cooling of the steel billet and affecting the shaping effect of rolling.

[0017] 2. The utility model sets a baffle. After the steel billet passes through the rolling roller, it will contact the baffle. Since the baffle is fixedly connected to the movable end of the pneumatic spring, when the steel billet moves under the drive of the rolling roller, the relative distance between the baffle and the insulation tube will change, so that the baffle stretches the pneumatic spring. The reaction force applied by the pneumatic spring to the baffle will be transmitted to the steel billet. Therefore, after the steel billet passes through the rolling roller, the end of the steel billet is still in contact with the rolling roller, which makes it easier for the steel billet to move when the rolling roller reverses. In this way, the steel billet can be repeatedly rolled. BRIEF DESCRIPTION OF THE DRAWINGS
