Description

Plunger type laminar flow cooling device

TECHNICAL FIELD The present invention relates to a hot rolled lamina flow cooling device in the field of metallurgy, and more particularly, to a cooling device which can adjust a lamina flow width and is applied to a metal production line for rolled steel.

Lamina flow chillers are used in hot continuous pressure production lines in steel companies, whose main function is to manufacture the target temperature set by coiling and to rapidly cool the strip steel exiting the rolling outlet.

For example, in the 2050 hot rolling mill of BAOSHAN IRON & STEEL CO., LTD., The lamina flow chiller has 76 groups of cooling manifolds (one upper manifold and one corresponding lower manifold). Folds constitute one group). Of these, 68 groups in the front constitute the main cooling station, and 8 groups in the rear constitute the finish cooling section. In general, it is divided into a plurality of cooling zones, each cooling zone consisting of its own main cooling system and a cooling zone of the finishing cooling section, the main cooling section of the cooling zone having a plurality of groups of robust cooling manifolds and It consists of a plurality of groups of main cooling manifolds. The valve group of the manifold being opened is calculated by the lamina cooling model according to the front to rear rules for the main cooling section and the front to rear rules for the finishing cooling section. As the set temperature from the finish rolling temperature to the coiling temperature drops, the front four groups of the main cooling section and the last four groups of the finishing cooling section need to be opened during each setting process, so they are basically Normally open, and in the basic automatic control method, there are data for the positions of each group of manifolds (from the final finishing rolling machine framing), and the band steel on the lamina flow rolling roll table. Their position needs to be tracked according to basic automatic control. The cooling control method is as follows.

Firstly, the number of groups of cooling manifolds located in the main cooling section and the finishing cooling section being opened is determined by the process machine by calculation by the lamina cooling model according to the set finishing rolling temperature and the coiling temperature. Commands are sent to the basic automatic control to control the water valve.

Secondly, after the strip steel sheet exits the final finish rolling machine framing, and after the actual finish rolling temperature of the strip steel sheet is measured by a thermometer used after finish rolling, the number of groups of cooling manifolds to be opened accordingly It is adjusted again.

Finally, after the actual coiling temperature of the strip steel is measured by the coiling thermometer used after lamina cooling, the number of groups of lamina flow cooling manifolds opened is dynamically adjusted according to the set coiling target. Thus, the coiling temperature of the strip steel is within the set range. The temperature of the strip steel is adjusted to 5 ° C. according to the amount of cooling water in each valve group.

The steel sheet geometry of hot rolled band steel is of the greatest interest to the user, and the quality of the steel sheet shape directly affects the use of the product, especially with the recent rapid development of the steel industry, the application field of the steel sheet is continuously Increasingly, the user's requirements for the quality of the steel sheet shape is increasing day by day.

As the hot rolled product production line continues to develop, the types and specifications of production are expanding accordingly, the current product structure is completely different from the previous product structure, the former product structures were mainly carbon steel, Micro alloy steels and carbon-magnesium steels are produced. In accordance with the rolling specifications of rolling production lines that are being developed continuously and the user demands for ever-increasing product quality, the current lamina flow cooling system is designed to produce various types of steel, namely alloy elements (BS 600, It is difficult to meet the production conditions of some steels such as BS 700, BS10L, S45C, SS400, etc. In the present lamina flow cooling system, there are existing problems such as instability of water pressure and uneven distribution of water flow, resulting in non-uniform cooling in the strip steel, which causes problems in the quality of the steel sheet shape of the strip steel. Thus, after such high strength steel passes through the lamina flow cooling zone, and after passing through the rolling production line production process, C-type wrapping and width direction caused by uneven cooling of the strip steel Steel plate shape problems that are changed by non-uniform cooling of easily occur, especially large temperature drops at the edges create internal stresses, which internally corrugate in both lateral directions during subsequent cooling processes, and In the width direction of the steel, it affects the steel sheet shape, mechanical performance, temperature and phase changes.

Lamina flow cooling affects the steel plate shape mainly through phase change, stress and thermal conductivity. Edge masking devices are known at home and abroad as an effective solution, which provides a substantial effect. At present, the German SMS-DMG and EDGER MAKING edge masking technology is mainly used in China, and the masking plate for masking the width of the upstream jet coolant of lamina flow cooling is connected to the connection mechanism controlled by the oil cylinder. Is adjusted. For example, edge masking technology was applied to the second project of the hot rolled CSP production line of HAN Steel in 2003.

In JP2002361316A of the "Band Material Cooling Device" filed December 17, 2002 by Mitsubishi Heavy Industries, Japan, the technical solution is to check the temperature at the edge of the strip steel during the lamina flow cooling process. The storage tank was used to collect the cooling water at the edge of the steel strip, and the cooling water collected by the water storage tank was discharged through the discharge pipe. This technique has the following disadvantages, i.e., when a narrow band steel is produced, a large amount of water is consumed.

Kawasaki Michushima Plant (Japan) developed research on the technique of masking the edges of lamina flow to improve the steel plate shape in the 1980s, and Kawasaki Steel Co., Ltd. Patent Date and Application Publication No .: Dec. 16, 1987, patent number CN87100594) was obtained, and a lamina flow nozzle consisting of a pair of flat steel sheet making slits was used for a lamina flow cooling device. The coolant grid allows the coolant to flow through these slits to adjust the passage area within such a nozzle, and at least one of the flat plates for the lamina flow nozzle is in a direction perpendicular to the flow direction of the coolant. And at least one of the flat plates is advantageous It causes changes in the passage in response to water pressure in, thereby adjusting the cooling water passage region. This solution uses a method of masking the edge of the lamina flow cooling manifold, and thus can provide a method for solving the problems of significantly reducing the temperature at the edge of the strip steel. Has the following problems. That is, as a narrower band steel is produced, there is a problem in that a large amount of cooling water is consumed, and a problem in which manufacturing resources cannot be saved.

The method of increasing the temperature at the edge of the strip steel according to the prior art applies the same principle of masking the width of the edge of the lamina flow manifold, thereby solving the problem that the temperature drop at the edge of the strip steel is too large. However, this method has the same problems as the following.

1. Resource consumption: When a narrow strip of steel is produced, a large amount of masked coolant is consumed, and thus there is a problem in that it can not save manufacturing resources, and there is a problem of increasing electricity consumption and water treatment cost.

2. Environmental impact: The coolant branched on both sides by the masking plate used for lamina flow cooling adversely affects the motor and lamina flow rolling table bearing base, and even if the guide plate is used, the environment is somewhat bad. Has a problem.

3. High failure rate: When the band steel is deflected, the masking plate for the edge part at two sides cannot be adjusted at the same time, and if the band deflection is large, the masking plate for the edge part at one side is masked. It cannot be performed, and if the band steel is deflected, there is a problem that cannot be used normally.

4. Mechanism shutdown: The lamina flow has a very poor cooling environment, and there is a problem that the coupling mechanism is often stopped.

5. Bad precision: Since the masking plate of the connection mechanism is easily deformed, there is a problem that the masking precision on both sides cannot meet the requirements.

6. Loaded steel easily damaged: If loaded steel occurs in the lamina flow cooling section, deformation and damage are easily caused by the connection mechanism and masking plate.

7. No masking for downward jetting: The connection mechanism cannot be used for cooling the downward jet lamina flow, and without the masking device for the downward jet lamina flow, the upper and lower surfaces of the strip are uniform. There is a problem in that it is not cooled, thereby creating a waveform at the edge of the strip steel.

Accordingly, the present inventors have invented a lamina flow cooling device, which is a gap lamina corresponding to the band steel passage width according to the cooling needs of different widths of the strip steel in order to obtain a change in the width direction in the lamina flow cooling region. To form a flow, and to reduce the temperature drop at the edge of the strip steel and to obtain plate shape, mechanical performance and uniformity of temperature and phase change of the strip steel in the width direction, Cooling water can be adjusted. The apparatus and control method are different from the conventional edge masking techniques and have the advantage of reducing the use of a large amount of coolant.

It is therefore an object of the present invention to provide a plunger type lamina flow cooling device capable of improving the phenomenon in a conventional lamina flow cooling system in which the cooling distribution occurs unevenly in the width direction of the strip steel. In order to obtain a change in the width direction in the lamina flow cooling region, the gap lamina flow corresponding to the width of the steel strip passage is formed according to the cooling needs of the different widths of the steel strip, and the temperature drop at the edge of the steel strip is reduced and In order to obtain the plate shape, the mechanical performance, and the uniformity of the temperature and phase change of the strip steel in the width direction, the cooling water in the region can be adjusted in the direction of the pass width.
