Abstract
The utility model relates to a high-density U-shaped pipe laminar cooling device, and belongs to the technical field of the design and the manufacturing of U-shaped pipe laminar cooling devices for rolled steel. A water inlet pipe is arranged in a water tank. A throttling orifice is formed on the water inlet pipe. A steady flow plate is arranged at the upper part of the water inlet pipe. A voltage stabilizing steady flow box is arranged on one side of an exhaust valve. A shielding funnel is arranged on a slide rail. A cycloidal needle-toothed planet speed reducer is arranged outside the water tank. When in use, the high-density U-shaped pipe laminar cooling device is arranged at the upper part of the table frame of a rolled steel plate. Cooling water enters the water inlet pipe in a cooling box body; and after flowing across the steady flow plate in a water tank body, water after being subjected to steady flow ensures that the water velocity at each part in the water tank is uniform and the water flow capacity is identical; and the cooling water enters a high-density U-shaped pipe in the laminar state and is impacted on the surface of the cooling steel plate, thereby achieving the quick cooling purposes of consistent water flowing density at each part on the transverse section of the steel plate and uniform transverse temperature control. The utility model improves the technological characteristics of the steel plate and solves the practical problems of the prior device such as non-uniform water flowing density and non-uniform transverse temperature control of the steel plate.
Description
Technical field
The utility model belongs to design and the manufacturing technology field of steel rolling with U type pipe cooling device.
Background technology
The raising of the operational characteristic of hot rolled steel plate can be organized by the correction chemical element or by particular form to a great extent and form, and obtains to require an approach of tissue signature just to be to use controlled rolling and control process for cooling.By the control cooling device the tough row of steel is further improved, simultaneously welding performance be improved.High density U type pipe cooling facility for laminar flow was owing to the reason in the design in the past, irregular to making the cooling water that enters in the casing flow rate of water flow at two ends occur, the discharge difference, therefore cause cooling water flow behind surface of steel plate, jet density inequality everywhere on the steel plate cross section, make the control of steel plate transverse temperature uneven, have a strong impact on steel product quality.
Summary of the invention
It is even that the purpose of this utility model provides a kind of cooling water flow velocity in casing that makes, and the U type pipe cooling facility for laminar flow that flow is identical is to solve the practical problem that existing product exists.
Structure of the present utility model is as shown in drawings: on the top of water tank one case lid is arranged.One water inlet pipe is arranged in water tank.Have throttle orifice on the water inlet pipe.On the top of water inlet pipe one stabilier is arranged.Have U type pipe on case lid, an end of U type pipe and case lid are welded connection.The other end is to working face.On a side of water tank, an air bleeding valve is arranged.One voltage stabilization and current stabilization case is arranged on air bleeding valve one side.In the bottom of water tank one funnel slideway is arranged, have on the slideway and cover funnel.In the outside of water tank one cycloid pin tooth planetary reducer is arranged, a sprocket wheel is arranged on the output shaft of reductor.By chain with cover funnel and be connected.Both ends at chain have stretcher.On the water tank both sides, have fixed mount.Fixed mount connects mutually with U type pipe, has sewage draining exit in the bottom, left side of water tank.Use of the present utility model is the roller bed frame top that it is installed in rolled steel plate, and water inlet pipe is connected with elevated tank.Its method of work is: cooling water is entered in the water inlet pipe that cools off in the casing through intermediate duct and control valve group by elevated tank, carry out current stabilization through throttle orifice, behind the stabilier of water behind the current stabilization in water tank, make in the water tank flow rate of water flow everywhere even, discharge is identical, this moment, cooling water was to enter in the high density U type pipe and impact on the surface of the steel plate that is cooled with laminar condition, thereby reach on the steel plate cross section jet density unanimity everywhere, transverse temperature control is cooling purpose fast uniformly.For entrained gas in the water in the emptying water tank, can discharge by the internal thread ball valve.Voltage stabilizing liquid stream case has guaranteed the stable water pressure in the cooling device.In order to solve steel plate width direction temperature inequality, be provided with the edge part shading device that changes to the narrowest adjustment from the wideest.The transmission of edge part shading is to be undertaken by cycloid pin tooth planetary reducer, drives by the sprocket chain bar and covers funnel left-right symmetry slip on the funnel slideway, and the chain tightness is regulated automatically by tensioning apparatus.The cooling water of crested flows in the trench via covering funnel.High-pressure side water spray and side-jetting are swept and residual water and the fog that is stranded on the steel plate can be blown down, and with heat exchange condition and accurate detection that guarantees the cooling water maximum, thereby reach best cooling effect.U type water inlet tube mouth weldbonding is undertaken firmly by fixed mount on case lid.For the sewage in the emptying cooling casing, finish by the sewage draining exit that is provided with.
