Description
Technical Field
The utility model relates to a bale long mouth of a river clearance instrument, concretely relates to an instrument for being convenient for clear up bale long mouth of a river cold steel belongs to bale long mouth of a river clearance instrument technical field.
Background
In molten steel continuous casting production equipment, a special long nozzle is tightly sleeved on a lower nozzle of a large ladle, and inert atmosphere such as Ar gas is supplemented to a bowl part of the long nozzle, so that casting flow from the large ladle to a tundish is isolated from air, the molten steel is protected from being polluted by oxygen and nitrogen in the air, meanwhile, the long nozzle also has the functions of preventing the molten steel from splashing and preserving heat, and the temperature drop in the pouring process of the large ladle is reduced; the long nozzle is one of the core parts of the equipment and is mainly made of aluminum-carbon refractory materials; as shown in fig. 1 and 2, the neck supported part of the conventional long nozzle 1 is designed in a step shape, and is supported by a trunnion ring 2 which is also designed in a step shape; because a gap exists between the bowl mouth of the long nozzle 1 and the ladle nozzle 3, the gap can be filled with molten steel in the using process, the molten steel is cooled and solidified into cold steel, the more cold steel at the bowl mouth is accumulated, the sealing performance of the ladle long nozzle 1 and the ladle nozzle 3 can be influenced, and the bowl mouth of the long nozzle can be seriously blown out of steel, so that a pouring 2-3 furnace can clean the cold steel at the bowl mouth of the long nozzle by using oxygen, the normal use of the long nozzle is ensured, and when the long nozzle needs to be cleaned (the long nozzle is burnt), a fixed place is not provided, and the cold steel can only be placed at the overflow port of a tundish; when the long nozzle is burnt, the cold steel in the long nozzle flows to the tundish overflow port in a melting way, and the tundish overflow port is blocked; the long nozzle is cleaned every 2-3 furnaces, and the cold steel scrap at the tundish overflow port is extremely thick, so that the slag cannot be discharged by staff; the overflow port of the tundish needs to be cleaned by staff before deslagging each time, and because the cold steel is extremely thick and is extremely close to the long nozzle, the temperature of the long nozzle is up to over 600 ℃, the cleaning difficulty of the staff is high, the working strength is high, and the ladle port needs to be cleaned for about 30min for one time; when the overflow port is cleaned, steel flowers splash, and potential safety hazards of scalding exist.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an instrument for being convenient for clear up long mouth of a river cold steel of bale erects in well package overflow mouth avris, makes in the long mouth of a river molten steel flow to well package overflow mouth below the accident hole in, stops when watering and the cold steel in the accident hole clears up.
The utility model discloses a tool for being convenient for clear up big package long nozzle cold steel, place the tool on the little platform next to the package overflow mouth, support one end towards the accident hole direction, the other end towards big package worker direction; when the long nozzle is burnt, the manipulator is operated to place the ladle long nozzle on the bracket, and the ladle worker uses the oxygen lance to clean cold steel in the long nozzle; after the clearance, big package worker manipulator rises long mouth of a river, prepares to overlap big package mouth of a river, and its concrete structure is as follows: the device comprises an elongated slot for placing a long nozzle, wherein a support base is welded at the bottom of the elongated slot, and the welded elongated slot is arranged in a downward inclined manner; baffles for preventing the long nozzle from sliding downwards are welded on two sides of the low end of the long groove respectively; the support base is fixed on a small platform beside an overflow port of the tundish, the low end of the elongated slot faces to an accident pit, and the other end of the elongated slot faces to the direction of a large tundish worker.
Further, the long groove is made of U-shaped steel, and the baffle is made of triangular iron; and a cold steel diversion gap is arranged between the baffle and the bottom surface of the inner side of the long groove.
Furthermore, the inclination angle of the long groove is 45-60 degrees.
Compared with the prior art, the utility model discloses an instrument for being convenient for clear up long mouth of a river cold steel of bale has following advantage:
1. molten steel melted in the long nozzle directly flows into the accident pit when the long nozzle is burnt, the overflow port of the tundish is not blocked, workers do not need to clean the overflow port, and the labor intensity of the workers is greatly reduced.
2. The potential safety hazard of scalding caused by steel splash is eliminated, and the working efficiency is improved.
