Abstract
The invention discloses an absorbing casting pipe for vacuum ingot casting and a use method of the absorbing casting pipe, and belongs to the field of vacuum ingot casting. The absorbing casting pipe for the vacuum ingot casting is composed of a pipe body, a prefabricated steel bushing, an iron shell and refractory mortar. The pipe body is made of a refractory material, and the prefabricated steel bushing is a steel sleeve with an inner cavity coincident with the appearance of a bowl opening; and a mounting table is arranged on the upper portion of the prefabricated steel bushing, and eight pin inserting holes are evenly distributed in the mounting table. The absorbing casting pipe for the vacuum ingot casting is fixed to a clamping device through the pin inserting holes and then is inserted into molten steel of a steel ladle, and the steel ladle moves up and down through a lifting mechanism; on the basis of the siphon principle, the molten steel continuously flows into the vacuum chamber, it is ensured that the casting operation is carried out continuously, and the production efficiency is improved; the tundish link is omitted, auxiliary materials such as manpower and material resources used by tundish constructing, a tundish plug rod or a plug stick matched with a tundish and flow guide pipes with a tundish connected to the steel ladle and a vacuum chamber are saved, and production cost is reduced.
Description
Technical field
The invention belongs to vacuum-casting field, relate generally to a kind of suction depositing used for vacuum ingot casting and using method thereof.
Background technology
Vacuum-casting, also known as vacuum pouring, is insert in vacuum chamber by ingot mould, and molten steel injects by the tundish be placed on vacuum chamber lid the molten steel vacuum processing techniques that steel ingot cast by ingot mould.Vacuum-casting device comprises vavuum pump, chassis, ingot mould, vacuum chamber, hot top, tundish and steel ladle and casting refractory etc.In order to build vacuum environment, between vacuum chamber, vacuum cover, tundish, use heat-resisting rubber sealing.In order to aim at ingot mould when ensureing that molten steel enters vacuum chamber, below vacuum cover, mozzle is housed, the molten steel just diffusing into thread after making to enter vacuum chamber space easily aims at ingot mould.Vacuum ingot casting process is only applicable to Room one ingot, multiplex come casting large forging-grade ingot.
In actual production, tundish capacity mostly is 150 ~ 200 tons, if need cast the steel ingot of more than 200 tons, then needs to supplement molten steel in time by the steel ladle of side placed on it.This process need carries out the series of complex operations such as closedown tundish, makes troubles, reduce production efficiency to casting cycle, and the casting bay of long period is every being difficult to ensure ingot quality.Therefore, the limitation that a kind of new method solves existing vacuum-casting device and technique casting heavy casting and forging is needed badly.
Summary of the invention
Technical problem to be solved by this invention is, overcome in existing vacuum ingot casting process casting heavy casting and forging process and need to supplement molten steel to tundish thus reduce the shortcoming that production efficiency even affects ingot quality, a kind of suction depositing used for vacuum ingot casting and using method thereof are provided.
In order to solve the problems referred to above that existing vacuum ingot casting process exists, the present invention adopts following technical proposals to realize: this suction depositing used for vacuum ingot casting is made up of body, prefabricated steel bushing, iron-clad and fire clay four part, body material is refractory material, comprise the rim of a bowl and pipe shaft two parts, prefabricated steel bushing is the inner chamber steel overcoat consistent with the rim of a bowl external form, and its top is the erecting bed that an external diameter is greater than the rim of a bowl external diameter, erecting bed is evenly distributed with 8 pin holes.
The present invention also has following technical characteristic: described suction depositing used for vacuum ingot casting and using method thereof are, suction depositing used for vacuum ingot casting is fixed on clamping device by the pin hole on erecting bed, then be inserted in the molten steel of steel ladle, the clamping device other end is the mozzle of the refractory material laying extended to above vacuum cover, by rubber sealing between mozzle and vacuum chamber, control the open and close of molten steel with sliding plate brick.Steel ladle moving up and down by elevating mechanism, suction depositing used for vacuum ingot casting is inserted in molten steel all the time, and by siphon principle, molten steel constantly flows into vacuum chamber, sprays in ingot mould with droplet shape, ensures that casting operation carries out continuously.
Advantage of the present invention and good effect are, the use of suction depositing used for vacuum ingot casting, when cancelling indispensable tundish in traditional vacuum casting ingot process, directly vacuum chamber is connected with steel ladle, adopt siphon principle, for vacuum chamber provides molten steel continuously, remove the process of stopping watering supplementary molten steel from, substantially increase production efficiency.Owing to eliminating tundish storage molten steel link, save tundish thereupon and build the auxiliary material such as human and material resources used and the supporting tundish stopper rod of tundish or stopper and tundish is connected to steel ladle, tundish is connected to vacuum chamber mozzle by laying bricks or stones, reduce production cost.
