Abstract

The utility model relates to a functional refractory material for an iron and steel metallurgical industry, in particular to a split-type steel-leakage preventing ladle ventilating seat brick, which comprises an upper ventilating seat brick body and a lower ventilating seat brick body, wherein the upper ventilating seat brick body and the lower ventilating seat brick body are matched in the mode of child and mother mouths, and a step is designed at the bottom of the lower ventilating seat brick body. The utility model has the advantages that the security of a ladle ventilating brick in the use process is enhanced, and a steel-leakage danger brought by seat brick cracking and straight-through gaps formed between the ladle ventilating brick and the ladle bottom when building is avoided. When the ventilating seat brick is replaced in the use process, only the upper ventilating seat brick body needs to be replaced, and the lower ventilating seat brick body can be repeatedly used, thereby the production cost is saved, and the material waste is reduced.

Description

The split type ladle of a kind of anti-bleed-out brick cup of breathing freely

Technical field

The utility model relates to the ventilative brick cup of the split type ladle of a kind of anti-bleed-out, belongs to the functional fire resisting material field of iron and steel metallurgical industry.

Background technology

Air brick of steel ladle is mounted in the gas supply element of ladle bottom, is blown into argon gas by the pipeline that links to each other with the gas permeable brick core during work molten steel is stirred, and reaches the effect of homogenizing molten steel, removal impurity.At iron and steel metallurgical industry, along with the increase of variety steel, high-quality output of steel, increasing iron and steel enterprise adopts refining modes such as LF, VD, RH in steelmaking process.This process for making requires air brick of steel ladle must guarantee high through-blowing rate, in case situations such as the gas permeable brick core is airtight, the erosion of brick core material is too fast occur, need carry out urgent ladle-to-ladle processing or change gas permeable brick, bring very big difficulty, have bigger potential safety hazard simultaneously to organization of production.The fitted outside gas permeable brick has characteristics such as quick replacing, easy construction, has obtained promotion and application just gradually.The fitted outside gas permeable brick is made up of gas permeable brick core and ventilative brick cup, and the gas permeable brick core is installed in the ventilative brick cup, need change the gas permeable brick core when normally using.If it is airtight or Air permenbility is too little to run into the gas permeable brick core, only need the hot gas permeable brick core of changing down get final product, save ladle greatly and built by laying the time, guaranteed the continuity of production.

The ventilative brick cup of ladle is divided into according to profile: monoblock type and split type.What adopt at present extensively is the ventilative brick cup of monoblock type, has good integrity, is convenient to characteristics such as installation.Wash away effect with the temperature rapid heat cycle because the ventilative brick cup of ladle in use is subjected to molten steel, especially using the later stage, ventilative brick cup can occur laterally or crackle longitudinally, and these crackles provide passage for the infiltration of molten steel, and the bleed-out accident takes place easily.Adopt split type ventilative brick cup can effectively avoid the generation of bleed-out accident.Document CN 201065417Y, the patent No. 200720012624.0 has been introduced " a kind of structure that prevents ventilative brick cup bleed-out ", and this structure belongs to split type ventilative brick cup.Comprising breathes freely goes up brick cup brick body and ventilative brick cup brick body down, and both build by laying bricks or stones together with the cooperation of mother-son mouth form.This structure has been strengthened the safety performance of ventilative brick cup, and when going up brick cup brick body and ventilative brick cup brick body down and big crackle occurring, gap, mother-son mouth combination section still is in the safety margin scope, has avoided ventilative up and down brick cup the gap to occur and the bleed-out accident takes place when ventilative.This structure when building by laying bricks or stones with the bag combining of bottom material be through-type.Because air brick of steel ladle adopts pointings (ramming mass or self-flowing material) to construct when building by laying bricks or stones and between the bag bottom material more; because of the pointing excessive erosion pit appears through regular meeting in use; molten steel can directly be penetrated into ladle bottom along pit; this through-type structure forms the bleed-out passage easily, has great potential safety hazard.

Summary of the invention

The utility model provides the split type ladle of a kind of anti-bleed-out brick cup of breathing freely.The ventilative brick cup of this ladle adopts split-type structural, and has increased step in ventilative brick cup bottom, and ventilative brick cup of ladle and the straight-through slit that the bag end forms when having avoided building by laying bricks or stones prevent that bleed-out from taking place.

To achieve these goals, the utility model is by the following technical solutions:

The split type ladle of a kind of anti-bleed-out brick cup of breathing freely comprising ventilative brick cup brick body and the ventilative brick cup brick body down gone up, and both cooperate with the mother-son mouth form, and ventilative brick cup brick body bottom design down has step.

The above ventilative brick cup brick body of going up is right cylinder or cubic cylinder with ventilative brick cup brick body down.

Compared with prior art, advantage of the present utility model is: increased gas permeable brick security in use, both avoided since the brick cup cracking bring ooze steel danger, prevented the straight-through slit that air brick of steel ladle forms with the bag end again when building by laying bricks or stones.When reality is used, in the time of need changing ventilative brick cup, only need change the ventilative brick cup brick body of going up simultaneously, ventilative brick cup brick body down can use repeatedly, has saved production cost, has reduced waste of material.
