Description
Technical field
The utility model relates to a kind of device of controlling converter tapping hole molten steel flow, particularly a kind of device that is installed in converter bottom tapping hole control molten steel flow.
Background technology
Steel mill generally all is to smelt good molten steel at present, tumbles from converter top and pours in the tundish, and molten steel flows out from the tapping hole of tundish bottom.After molten steel is poured tundish in the converter, the mixture that is mingled with that is suspended in converter molten steel top is also together poured in the tundish with molten steel, for improving the degree of purity of molten steel, after must making being mingled with mixture and floating to the surface of molten steel on fully in the molten steel, just the tapping hole of tundish bottom is opened and emitted molten steel.Be mingled with the mixture come-up and need the regular hour, general 8-10 minute.
Summary of the invention
The purpose of this utility model is in order directly to go out molten steel and a kind of device that converter bottom tapping hole is used for controlling molten steel flow that is installed in to be provided at converter bottom tapping hole.
The technical solution of the utility model is: a kind of device of controlling converter tapping hole molten steel flow, it comprises a mozzle and a supporting base that is installed on the body of heater that converter bottom tapping hole is installed, mozzle adopts refractory material to make, mozzle is directly tamped the tapping hole in the converter bottom, port at converter bottom tapping hole mozzle is provided with a plug made from refractory material, utilizes plug that the pod apertures of mozzle is sealed.In addition, with the supporting base that is installed on the body of heater mozzle is held, and mozzle is fixed on supporting base by a semicircular cover plate and bolt.In the pin hole of supporting base, be provided with a pivot pin, pivot pin is fixed in the pin hole of supporting base by pin, on pivot pin, be provided with the runing rest of a disk spring and a band handle successively, disk spring is arranged between supporting base and the runing rest, on pivot pin, be provided with a wedge groove, one end of wedge groove is designed to the inclined-plane, is inserted with a wedge in the wedge groove, by wedge disk spring and runing rest is fixed on the pivot pin.Be provided with a shutoff dish made from refractory material in the tray frame of the runing rest other end, the shutoff dish contacts with the end face of mozzle, by adjusting wedge, makes the contact-making surface of shutoff dish and mozzle end face reach seal request.Be provided with a tapping hole on the tray frame of runing rest, also be provided with a tapping hole on the shutoff dish, when the shutoff dish was installed in the tray frame, the tapping hole on the shutoff dish will be aimed at the tapping hole on the tray frame.
During tapping, rotate runing rest by handle, the pod apertures that makes the tapping hole on tray frame and the shutoff dish aim at mozzle is disclosed out the plug in the pod apertures with drill rod, and molten steel flows out from the tapping hole of tapping hole on pod apertures and tray frame and shutoff dish of converter bottom.At this moment, rotate runing rest, adjust the tapping hole gap on pod apertures and tray frame and the shutoff dish, just can control the flow of molten steel by handle.
The utility model compared with prior art has following characteristics:
1, molten steel directly flows out from the tapping hole of converter bottom, the molten steel of having saved converter is waited for the time that is mingled with the mixture come-up after pouring tundish into, effectively improved the quality that flows out molten steel, this needs the process environments of continuous constant flow rate molten steel to those, as twin-roll cast-rolling mill etc., effectively improve production efficiency and product quality.
2, molten steel directly flows out from the tapping hole of converter bottom, has reduced the middle swivel link of tundish, has reduced the temperature loss of molten steel.
