Abstract
The utility model relates to a medium-frequency steelmaking molten steel refining device. Molten steel in a steelmaking furnace usually contains harmful gases and some impurities, and the key point to improve steelmaking quality is how to remove the impurities. The medium-frequency steelmaking molten steel refining device comprises a medium-frequency furnace tank, and is characterized in that a fireproof gas transmission guide tube is inserted in the medium-frequency furnace tank. The medium-frequency steelmaking molten steel refining device further comprises a controller which is externally connected with a gas inlet tube and a gas outlet tube, wherein a pressure detecting meter is arranged on the controller; the gas outlet tube is connected with a flow rate meter; the gas outlet tube is connected with the gas transmission guide tube. The medium-frequency steelmaking molten steel refining device disclosed by the utility model can remove harmful gasses and impurities in the molten steel out of the molten steel by regulating pressure and flow rate of inert gas introduced to the molten steel via the controller, so that refining effects for purifying the molten steel are achieved, and subsequent steelmaking purity and quality are effectively improved.
Description
Technical field
The utility model relates to a kind of intermediate frequency refining molten steel refining device.
Background technology
Molten steel in steel melting furnace contains obnoxious flavour and some impurity conventionally, and how removing these impurity is the key points that improve steel-making quality.
Utility model content
The purpose of this utility model is to provide a kind of intermediate frequency refining molten steel refining device, can carry out refining and cleaning action to molten steel, improves purity and the quality of follow-up steel-making.
For this reason, the utility model is taked following technical scheme: a kind of intermediate frequency refining molten steel refining device, comprise intermediate frequency furnace hearth, it is characterized in that inserting a fire-resistant gas transmission conduit in described intermediate frequency furnace hearth, also comprise a controller, the external inlet pipe of controller and escape pipe, arrange pressure detection table on controller, described escape pipe connection traffic meter, described escape pipe is connected with described gas transmission conduit.
Described gas transmission conduit upper end connects suspension ring, and described suspension ring are hung on a liftable suspension hook.Height that can adjusting lift hook by suspension hook, regulates gas transmission conduit to enter the position in intermediate frequency furnace hearth.
The upper end of described gas transmission conduit arranges back up pad, and the both sides of described back up pad arrange respectively fixture, and described fixture upper end arranges support bar, and described post upper connects escape pipe.Support bar is set can play a supporting role to escape pipe, makes air-flow operation smooth and easy, is also convenient to escape pipe and accesses gas pipe line from different azimuth.The clip position of fixture is adjustable, can change the support angle of support bar.
In described gas transmission conduit, pass into rare gas element.
The utility model regulates and controls to pass into inert gas pressure and the flow in molten steel by controller, the obnoxious flavour in molten steel and inclusion can be discharged to molten steel, thereby reach the refining effect of purify hot metal, effectively improves purity and the quality of follow-up steel-making.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
A kind of intermediate frequency refining molten steel refining device as shown in Figure 1, in intermediate frequency furnace hearth 1, insert a fire-resistant gas transmission conduit 2, also comprise a controller 11, the external inlet pipe 12 of controller 11 and escape pipe 8, pressure detection table 10 is set on controller 11, escape pipe 8 connection traffic meters 9, escape pipe 8 is connected with gas transmission conduit 2.In gas transmission conduit 2, pass into rare gas element.Gas transmission conduit 2 upper ends connect suspension ring 6, and suspension ring 6 are hung on a liftable suspension hook 7.The upper end of gas transmission conduit 2 arranges back up pad 5, and the both sides of back up pad 5 arrange respectively fixture 3, and fixture 3 upper ends arrange support bar 4, and support bar 4 upper ends connect escape pipe 8.
The utility model regulates and controls to pass into inert gas pressure and the flow in molten steel by controller, the obnoxious flavour in molten steel and inclusion can be discharged to molten steel, thereby reach the refining effect of purify hot metal, effectively improves purity and the quality of follow-up steel-making.
It needs to be noted, the mode of above-described embodiment only limits to describe embodiment, but the utility model is confined to aforesaid way incessantly, and those skilled in the art can modify easily not departing from scope of the present utility model accordingly, therefore scope of the present utility model should comprise principle that the utility model discloses and the maximum range of new feature.
