Abstract
The utility model provides a composite brick core of a bottom blowing air brick for ladle refining and relates to a brick core of a bottom blowing air brick for ladle refining. The composite brick core comprises a refractory body which is internally provided with a ventilation channel and is composed of a refractory body I and a refractory body II; the refractory body II is arranged at the periphery of the outer part of the refractory body I; the ventilation channel is arranged in the refractory body I and is arranged around the central axis of the refractory body I and along the direction of the central axis of the refractory body I. According to the composite brick core, the ablation to a seat brick of the air brick, caused by oxygen combustion operation, is relieved effectively; a gap between the seat brick and the brick core is small after an outer splitting type air brick is replaced, so that the adding amount of repairing materials is relatively less; the seat brick can protect the brick core effectively so as to prolong the service life of the air brick.
Description
Technical field
The utility model relates to bottom-blown air brick brick core for a kind of ladle refining, particularly relates to a kind of safe and reliable, applicable exterior split type gas permeable brick composite brick core that blowing rate is high.
Background technology
Ladle bottom air blowing treatment is the degassed secondary refining method with removing non-metallic inclusion of a kind of easy molten steel.This mode stirs by pass into gas in molten steel, accelerates to realize metallurgical process, even liquid steel temperature and chemical composition, the form of promotion inclusion removal or control inclusion.To being blown into gas in molten steel, can obtain by two kinds of modes, a kind of is to adopt air blow gun, inserts the molten steel operation of blowing from ladle top; Another kind is to adopt the gas permeable brick that is arranged in ladle bottom, from ladle bottom, gas is sent into, and wherein bottom-blown air brick mode is more convenient, effective, thereby is widely used.
Gas permeable brick is as the important functional original paper of refining process, its in the course of the work safe and reliable use to guarantee refining process continue play an important role.In gas permeable brick use procedure major requirement its have and use the performances such as stable, blowing rate is high.
At present, the metal cover board that gas permeable brick core traditional structure generally includes brick core body refractory materials, be welded on steel bushing around of described refractory materials, weld together with steel bushing one end and one and the bridge welding metal tail pipe that is connected together, metal tail pipe is connected with external air source, gas can be incorporated into gas permeable brick core.Between metal cover board and gas permeable brick core body refractory materials, conventionally leave air chamber, between steel bushing and gas permeable brick core body refractory materials, with refractory mortar, seal.During gas permeable brick work, gas enters the air chamber of gas permeable brick core from metal tail pipe, then is blown in molten steel through the gas-permeable channels of gas permeable brick core inner setting, reaches the effect that stirs molten steel.
Tradition gas permeable brick brick core gas-permeable channels structure as shown in Figure 1, this layout is comparatively unfavorable to the use of split gas permeable brick, in the use procedure of brick core, in order to guarantee its ventilation property, often brick core working face is burnt to oxygen operation, in burning oxygen maintenance process, because operation is not meticulous and the defect of slit layout, easily make brick core brick cup around ablated, after changing gas permeable brick, brick cup is due to ablated, cause between brick cup and brick core gap larger, gas permeable brick is had to larger impact work-ing life.
Utility model content
In order to solve the problems of the technologies described above; the utility model provides a kind of ladle refining bottom-blown air brick composite brick core; this brick core adopts the structure of combined type; and the gas-permeable channels structure of traditional gas permeable brick brick core is improved, effectively alleviated the ablation to brick cup of air brick while burning oxygen operation, guaranteed that exterior split type gas permeable brick changes after brick; the gap of brick cup and brick core is less; the injected volume of repair material is relatively less, and brick cup can more effective protection tile core, and then improves gas permeable brick work-ing life.
To achieve these goals, the technical solution of the utility model is: a kind of ladle refining bottom-blown air brick composite brick core, comprise the body of resistance to material, resistance to material body interior is provided with gas-permeable channels, the described body of resistance to material consists of the body of resistance to material I and the body of resistance to material II, the body of resistance to material II is arranged on the periphery of the body of resistance to material I outside, and the body of resistance to material I inside is provided with gas-permeable channels, and described gas-permeable channels is arranged on the body of resistance to material I central axis around.
Described gas-permeable channels arranges along the body of resistance to material I central axial direction.
The lower surface of the described body of resistance to material II is positioned at the minimum safe altitude position of gas permeable brick.
Beneficial effect:
1, traditional gas permeable brick, in use because brick core inner gas-permeable channels layout is near brick cup, burns oxygen pipe and is easy to be swept into brick cup in hot repair burning oxygen process, causes the ablation of brick cup.The utility model is arranged on the body of resistance to material I central axis around by the gas-permeable channels of gas permeable brick brick core, near the position of brick core central axis, and gas permeable brick brick core adopts composite structure, in the outside of the brick core body of resistance to material I, wrap up in addition the body of the resistance to material II of high-quality materials, thereby gas-permeable channels and the brick cup of air brick of the brick core body of resistance to material I inside are kept apart effectively, in hot repair burning oxygen process, burn oxygen pipe like this and be difficult for being swept into brick cup, guaranteed the provide protection of brick cup to gas permeable brick core, particularly for fitted outside split brick, after installing, new brick core lessly can well protect new brick core because brick cup is etched, finally realize the gas permeable brick prolongation in work-ing life.
2, the gas-permeable channels of gas permeable brick brick core inner is improved to the vertical structure arranging along the body of resistance to material I central axial direction by traditional layout with tapering, this contributes to improve refining while blowing molten steel seethe effect.
3, the lower surface of the body of resistance to material II of the present utility model is positioned at the minimum safe altitude position of gas permeable brick, when gas permeable brick is used while disappearing to the later stage body of resistance to material II, show that it has used to minimum safe altitude, this structure arranges secure ID than traditional brick core inner and more easily distinguishes, and is conducive to the safe handling of gas permeable brick.
