Abstract
The utility model relates to a lower slide brick of a sliding mechanism for steel mould casting. The lower slide brick is arranged between a middle slide plate and a water outlet port; a lower slide brick body is provided with a flow guidance groove with a certain inclined angle in the water port closing direction of the middle slide plate of a sliding mechanism; and one side of the low guidance groove is communicated with a molten steel hole of a lower slide plate. According to the utility model, the flow guidance groove with a certain inclined angle, which is connected with the steel flowing hole of the lower slide plate, is designed on the upper plane of the lower slide brick of the sliding mechanism along the water port closing direction of the middle slide plate; and molten steel remaining in the steel flowing hole of the lower slide plate can be introduced to the flow guidance groove to flow away along the water outlet hole in the water closing process of the middle slide plate after the drainage of the molten steel, so that the molten steel can be prevented from being cooled in the steel flowing hole of the middle slide plate to block the water port so as to realize the multiple-time interrupted casting.
Description
Technical field
The utility model relates to the used slide mechanism of a kind of iron and steel mold cast, and a kind of specifically iron and steel mold cast is with the lower skateboard brick of slide mechanism.
Background technology
In order to realize that high-quality clean molten steel is injected mold, way is to adopt stopper or slide gate mechanism usually, through the switching and the adjustment beam size of control ladle or middle water containing opening, reaches continuously or discontinuity is injected required molten steel amount in different molds.Guarantee that the mouth of a river opens and closes smoothly and the adjusting of beam size is controlled freely but all measures are all necessary.People open and close for the control mouth of a river and adjustment beam size, the method for same more employing valve-like gate control.Through the control technology that the various mouths of a river open and close, for example: adopt the slide gate nozzle technology, the basic role of slide gate nozzle is the molten steel flow of regulating ladle or tundish, and slide gate nozzle can carry out molten steel and dam, and it comprises a filling pipe end, a following mouth of a river and two slide plates.The following mouth of a river and lower skateboard are whole to be moved, and double-deck slide plate can't overcome adjustment beam mouth of a river displacement problem at present.
The mouth of a river is not subjected to displacement for solution continuous casting tundish slide gate nozzle flows at present at the adjustment steel, has occurred three layers of slide plate slides mechanism again.It comprises a filling pipe end; Three slide plates in a following mouth of a river and upper, middle and lower; Upper and lower slide plate is connected to a fixed on frame with the upper and lower mouth of a river respectively, relies on the switching and the big or small adjustment of steel stream at the mobile realization mouth of a river of the middle slide plate that has slide plate Argon device.Though three layers of slide plate have solved time mouth of a river displacement problem, can not realize repeatedly interrupted pour.Adopt the stopper placing, lean on the circular chock plug of stopper bottom in ladle or the tundish to compress ladle or middle water containing opening seals the mouth of a river, the stopper upper end is connected with ladle or tundish outside frame.Frame can make stopper move up and down, and adjustment chock plug and the gap between the mouth of a river can obtain the size of different beams.Adopt the stopper cast can not avoid stopper fusing, fall the chock plug problem, and deteriorating of stopper refractory material caused the pollution to molten steel, the generation secondary impurities.
The utility model content
The purpose of the utility model is to be the deficiency that solves the problems of the technologies described above, and the lower skateboard brick of a kind of iron and steel mold cast with slide mechanism is provided, and three layers of repeatedly interrupted pour of slide plate slides mechanism of the simple and effective realization of ability are enhanced productivity more than 80%.
The utility model is the deficiency that solves the problems of the technologies described above; The technical scheme that is adopted is: the cast of iron and steel mold is with the lower skateboard brick of slide mechanism; Be arranged between the middle slide plate and the following mouth of a river; The middle slide plate that is positioned at slide mechanism is closed the water conservancy diversion groove that on lower skateboard brick body, is provided with the band gradient on the direction of the mouth of a river, and water conservancy diversion groove one side is connected with the lower skateboard steel outlet hole.
The aperture of described water conservancy diversion groove port and the aperture of middle slide plate steel outlet hole equate.
The section configuration of described water conservancy diversion groove is made up of upper angled section and lower vertical section, and tilting section and vertical section junction are smooth joint face, and the height of vertical section is 5-8mm.
The gradient of described tilting section is 20～55 °.
The gradient of described tilting section is 28～45 °.
The beneficial effect of the utility model is:
The utility model is closed mouth of a river direction through plane on slide mechanism lower skateboard brick along middle slide plate; Design a water conservancy diversion groove that links to each other with the lower skateboard steel outlet hole that constant slope is arranged; After the molten steel drainage, middle slide plate is closed in the process of the mouth of a river, and the mouth of a river flowed away under the molten steel that is detained in the middle slide plate steel outlet hole can be introduced along the water conservancy diversion groove; Avoid the cold steel obstruction of the knot mouth of a river in the middle slide plate steel outlet hole, realize repeatedly interrupted pour.Through watering test in fact, adopt the ladle or the tundish of the teeming of the utility model slide mechanism lower skateboard brick can realize repeatedly interrupted pour.The utility model method does not produce reactant impurity, thereby can not cause new pollution.The utility model is realized the used slide mechanism lower skateboard of repeatedly interrupted pour brick, need not increase auxiliary device.The water conservancy diversion groove is set in slide mechanism lower skateboard brick wall is thick, simple in structure, easy to make, do not change the manufacturing process of slide mechanism lower skateboard brick basically.The downward-sloping straight-through mouth of a river down, the molten steel landing of being detained in the slide plate steel outlet hole in the middle of making more easily.
