Abstract
The utility model discloses an oxygen lance port gas-sealing device with an adjustable converter oxygen lance. The oxygen lance port gas-sealing device comprises a fixed sealing plate (1), a movable sealing plate (3), a pushing device (2) and a slide guide rail (6). The oxygen lance port gas-sealing device is characterized in that the fixed sealing plate (1) is arranged on the end cover of a converter; a ring hole matched with the oxygen lance is formed on the center of the fixed sealing plate; the movable sealing plate (3) is arranged above the fixed sealing plate (1); one end of the movable sealing plate (3) is connected with the pushing device (2) and is in sliding fit with the slide guide rail (6); jetting holes (5) are uniformly distributed in a radial direction on an inner circular ring of the movable sealing plate (3). According to the utility model, structures of the fixed sealing plate and the movable sealing plate are adopted to realize that the working position of the oxygen lance in the converter is adjustable, so that a coal gas recycling system of a converter system is in a relatively closed working environment, and therefore, influences of the outside on a coal gas atmosphere in a flue are lowered, and coal gas recycling time within a smelting period is improved. And meanwhile, the converter coal gas is prevented from flowing outwards to the greatest extent.
Description
Technical field
The utility model belongs to smelting iron and steel technical field, further belongs to converter gas recovery system technical field of sealing technology, be specifically related to a kind of simple in structure, cheap, the adjustable oxygen muzzle gas-tight sealing of converter oxygen gun of reliable operation.
Background technology
Oxygen converter steelmaking is to insert converter by oxygen rifle, and the carbon in Injection In Molten Iron oxygen blast qi exhaustion molten iron discharging is reached to smelting object.Converter system is made up of the Working environment of a relative closure revolving furnace body and flue, and entering converter, oxygen rifle must destroy the Working environment of this sealing, for ensureing that the original method adopting of original Working environment is seal cones of design and installation on oxygen rifle, form sealing by seal cones and oxygen muzzle.
In actual application, there is following problem in this structure situation:
1, sealing effectiveness is unreliable.Because sealing cone is mounted on oxygen rifle, inevitably can there is distortion and skew in oxygen rifle in use, and this all will cause sealing surface area to reduce, and flue gas is excessive.
2, position on oxygen rifle of sealing cone and the position of oxygen muzzle are fixed, and this has just determined on the working position of oxygen rifle in converter fixing.But have certain variation in the actual smelting process of converter at the Intake Quantity of molten iron, namely molten iron liquid level has certain variation.Oxygen rifle position and molten iron liquid level will not increase and smelt difficulty and affect molten steel quality at ideal position.
For this reason, research and development are a kind of simple in structure, cheap, reliable operation, and the adjustable oxygen muzzle gas-tight sealing of converter oxygen gun of reliable operation, is with a wide range of applications.
Utility model content
It is a kind of simple in structure, cheap that the purpose of this utility model is to provide, the adjustable oxygen muzzle gas-tight sealing of converter oxygen gun of reliable operation.
The purpose of this utility model is achieved in that and comprises fixing seal plate, movable sealing plate, thrust unit and rail plate; Described fixing seal plate is arranged on converter end cover, and its center arranges the annular distance coordinating with oxygen rifle; Described movable sealing plate is arranged at fixing seal plate top, and its one end is connected with thrust unit, and is slidably matched with rail plate, annulus radial equipartition jet hole within described movable sealing plate.
The utility model the utility model is by the structure of fixing seal plate and movable sealing plate, realize the adjustable of the working position of oxygen rifle in converter, ensure that converter system is still the Working environment of a relative closure simultaneously, reduced the difficulty of smelting, ensured the quality of molten steel.Transformation come into operation after, install reliable, favorable sealing property.Promoted the recovery of coal gas of converter, coal-gas recovering rate is from 85m
3/ ton steel is brought up to 110m
3/ ton steel.Play good economic benefit.The utility model is simple in structure, cheap, reliable operation.
