Abstract

This utility model relates to a cooling water guiding device for a roughing mill of profile steel, belonging to the technical field of auxiliary equipment for profile steel production in the metallurgical industry. The technical solution is as follows: it includes a base sleeve (1), a base (2), an adjustable baffle plate (3), and a mounting base plate (4). The two base sleeves (1) are respectively fixed on the base (2). The adjustable baffle plate (3) and the mounting base plate (4) are multiple pieces. The multiple mounting base plates (4) are respectively fixed on the base (2) between the two base sleeves (1). Each mounting base plate (4) is provided with an adjustable baffle plate (3). The shape of the front end of the adjustable baffle plate (3) matches the profile of the roughing mill. The beneficial effect of this utility model is that it can guide most of the cooling water of the roughing mill rolls to both sides of the profile steel, so that it no longer flows a large amount onto the profile steel being rolled, reducing the obvious temperature drop at the head and tail of the profile steel when it bites in during rolling, and eliminating the dimensional fluctuations at the head and tail caused by the temperature difference along the length of the profile steel.

Description

Technical Field

[0001] This utility model relates to a cooling water guiding device for a roughing mill for steel profiles, belonging to the technical field of auxiliary equipment for steel profile production in the metallurgical industry. Background Technology

[0002] In the production of structural steel, the cooling of the roughing mill rolls is mainly achieved by spraying high-pressure water through nozzles onto the roll passes. As the structural steel is reciprocated within the roughing mill, the cooling water flows along the roll passes to the surface of the steel. During the roughing mill's biting process, the steel enters at a low speed, resulting in a large amount of cooling water flowing to the upper surface of the steel. This causes the temperature within a 0.5-meter radius at the beginning and end of the section to be significantly lower than that in the middle. In subsequent rolling processes, the lower temperature at the beginning and end leads to increased rolling force, ultimately resulting in the dimensions of the hot-rolled structural steel within approximately 3 meters at the beginning and end being significantly larger than those in the middle of the length. This reduces the range of dimensional adjustments and increases the difficulty of adjustment for the workers. Furthermore, the lower temperature at the beginning and end of the section makes it highly susceptible to damage to the surface of the universal rolls, creating serious quality risks. Therefore, there is an urgent need to design a cooling water guiding device for a roughing mill of steel profiles, which can guide the cooling water of the upper roll of the roughing mill to the outside of the steel profile. Since the roll pass of the roughing mill is an irregular shape, a special water guide plate device that matches the pass shape is required to guide the cooling water of the roll. Utility Model Content

[0003] The purpose of this invention is to provide a cooling water guiding device for a roughing mill of steel profiles, which can guide most of the cooling water of the rolls of the roughing mill of steel profiles to both sides of the steel profile, so that it no longer flows in large quantities onto the steel profile being rolled, thereby reducing the obvious temperature drop at the head and tail of the steel profile during rolling bite, eliminating the dimensional fluctuations at the head and tail caused by the temperature difference along the entire length of the steel profile, and solving the problems existing in the background technology.

[0004] The technical solution of this utility model is:

[0005] A cooling water guiding device for a roughing mill of profile steel includes a base sleeve, a base, an adjustable baffle plate, and a mounting base plate. There are two base sleeves, which are respectively fixed on the base. There are multiple adjustable baffle plates and mounting base plates, which are respectively fixed on the base between the two base sleeves. Each mounting base plate is provided with an adjustable baffle plate, and the shape of the front end of the adjustable baffle plate matches the pass shape of the roughing mill.

[0006] The number of adjustable baffles and mounting base plates is matched with the roughing mill pass.

[0007] The adjustable baffle and mounting base are fixed to the base with bolts.

[0008] The adjustable water baffle is at a certain angle to the horizontal plane.

[0009] The mounting base plate is a rectangular plate.

[0010] The two base sleeves are fixed to the crossbeams of the upper roller system of the roughing mill.

[0011] The beneficial effects of this utility model are: it can effectively guide the cooling water of the upper roll of the roughing mill, so that it no longer flows into the section steel being rolled in large quantities, reduce the obvious temperature drop at the head and tail of the section steel during rolling, eliminate the dimensional fluctuation of the head and tail of the section steel caused by temperature difference, reduce the difficulty of adjusting the dimensions of the section steel, and improve the yield of section steel.

[0021] The present invention will be further described below with reference to the accompanying drawings and examples.

[0022] See attached document Figure 1-8 A cooling water guiding device for a roughing mill of profile steel includes a base sleeve 1, a base 2, an adjustable baffle plate 3, and a mounting base plate 4. There are two base sleeves 1, which are respectively fixed on the base 2. There are multiple adjustable baffle plates 3 and mounting base plates 4, which are respectively fixed on the base 2 between the two base sleeves 1. Each mounting base plate 4 is provided with an adjustable baffle plate 3. The shape of the front end of the adjustable baffle plate 3 matches the pass shape of the roughing mill.

[0023] In this embodiment, refer to the appendix Figure 1-8The cooling water guiding device includes two base sleeves 1, a base 2, several adjustable baffles 3, a mounting base plate 4, and bolts 5. The base 2 is welded to the two base sleeves 1. The base 2 is mounted on the crossbeam of the upper roller system through the two base sleeves 1. The height of the base 2 can be adjusted by the connecting bolts between the base 2 and the crossbeam of the upper roller system to accommodate upper roller systems of different diameters, so that it is located at a lower position on the axis of the upper roller system.

[0024] The number of mounting base plates 4 used depends on the number of BD roll holes. The mounting base plates 4 have the same specifications and dimensions. The mounting base plates 4 are installed on the base 2 by bolts 5 and can be adjusted left and right on the base 2 to align with the hole slot.

[0025] The adjustable baffle plate 3 is selected according to the BD die system. The front end of each adjustable baffle plate 3 matches each die and is connected to the mounting base plate 4 by bolts 5. Each adjustable baffle plate 3 can be adjusted back and forth individually to match its respective die. After the adjustable baffle plate 3 is installed, it forms a certain angle with the horizontal plane, which facilitates the flow of the roll cooling water from the roll groove to the outside of the roll and both sides of the die.
