Description

Technical Field

[0001] This invention belongs to the field of rolling mill guides, and in particular relates to a water-cooled inlet guide for finishing mills. Background Technology

[0002] Hot-rolled strip steel generally refers to coiled strip steel with a thickness of 1-20mm and a width of 300-2000mm. Hot-rolled strip steel can be used directly as hot-rolled steel plate or supplied as billet for cold-rolled strip steel. It is widely used in the automotive, motor, chemical, and shipbuilding industries, and also serves as billet for the production of cold-rolled, welded pipe, and cold-formed steel sections. Therefore, the demand for hot-rolled strip steel in my country is very large, with the total annual output reaching hundreds of millions of tons. The finishing mill is the most important piece of equipment on a strip steel production line, directly affecting whether the dimensions and properties of the finished strip steel meet customer requirements. The inlet guide of the finishing mill is an important supporting device, responsible for feeding the strip steel into the finishing mill for rolling.

[0003] With the increasing automation of strip steel production lines, the rolling pace is also accelerating. The time gap between two strips is very short, which means that the inlet guide of the finishing mill is always in contact with the strip without cooling time. The strip temperature is usually around 1000 degrees Celsius. After working for a long time, the guide temperature will rise rapidly, resulting in a shortened service life. At the same time, damage to the guide can easily cause steel pile-up accidents, affecting the production rhythm of the workshop and reducing output. Summary of the Invention

[0004] In view of this, the present invention aims to provide a precision rolling water-cooled inlet guide in order to solve at least one of the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A precision rolling mill water-cooled inlet guide includes:

[0007] A support member is located at the bottom of the steel strip to be guided, with the upper end face of the support member pressing against the lower end face of the steel strip.

[0008] The guide is provided in two sets, which are symmetrically arranged on both sides of the support. The two sets of guides and the support form a guide channel. The steel strip moves from the inlet end of the guide to the roll at the outlet end of the guide along the direction of the guide channel.

[0009] The base, the support member and the guide member are both mounted on the base;

[0010] Both the support and guide components are equipped with cooling structures.

[0011] Furthermore, the support component is a hollow structure with multiple baffles fixed inside. The multiple baffles divide the interior of the support component into multiple water storage chambers. Each baffle has a water passage hole. The two ends of the support component have water inlet holes and water outlet holes, respectively. The water inlet holes, multiple water storage chambers, and water outlet holes are connected in sequence to form the cooling structure inside the support component.

[0012] Furthermore, the upper surface of the support member is a plane, and a plurality of connecting blocks are fixedly provided on the lower surface. A plurality of fixing blocks corresponding to the connecting blocks are fixedly provided on the base, and the connecting blocks are fixedly connected to the fixing blocks.

[0013] Furthermore, the guide is movably connected to the top of the base, a hinge block is fixedly provided at the bottom of the guide, and a driving component corresponding to the guide is provided inside the base. The power output end of the driving component is hinged to the hinge block, and the housing of the driving component is hinged to the base.

[0014] Furthermore, a liner is provided on the side of the guide member adjacent to the support member. There are two liners, one liner located at the bottom of the steel strip and the other liner located on the side of the steel strip. Both liners are located at the inlet end of the guide member. Liquid passages are provided in both liners, and the liquid passages constitute a cooling structure inside the guide member.

[0015] Furthermore, the liquid passage is serpentine, with the inlet and outlet of the liquid passage located on the same side of the liner, and the inlet position being lower than the outlet position.

[0016] Furthermore, the liner has multiple fixing holes, and the guide has multiple fixing grooves corresponding to the fixing holes. Fixing bolts are installed in the fixing holes and are threaded through the fixing holes and connected to the fixing grooves.

[0017] Furthermore, a guide plate is provided on the side of the guide member adjacent to the support member. The guide plate is located at the top of the steel strip and at the outlet end of the guide member.

[0018] Compared with the prior art, the precision rolling water-cooled inlet guide of the present invention has the following beneficial effects: the heat on the guide is carried away by circulating water, so as to extend the service life of the guide, thereby reducing production costs, increasing equipment safety and stability, and improving production efficiency.
