Abstract
The utility model discloses a kind of improved converter taphole, including tapping hole body, tapping hole body is more than top bore of the tapping hole body close to stove inwall close to the bottom bore of furnace outer wall, and the intrinsic tapping hole inwall of tapping hole is less than or equal to 5.7 degree in cone, tapping hole inwall taper.
Description
Technical field
It the utility model is related to a kind of improved converter taphole.
Background technology
Original tapping hole front/rear end zero draft., it is necessary to be poured using gunning refractory after new tapping hole installation is fixed.
Due to relatively low close to body of heater lateral ends furnace body temperature（200 degree or so）, the material poured into is difficult to effectively sinter；In stove
One end temperature is higher（900-1000 degree）, it is a graded to grow from weak to strong from body of heater outside to furnace interior, temperature.Stove
Sintering solidification of the internal portion after gunning refractory pours into quickly, this further hinders effective filling close to space on the outside of body of heater,
Cause tapping hole space to be present close to body of heater lateral ends, easily occur bleed-out accident during use.Since two thousand and ten, 120t
Converter, which amounts to, occurs bleed-out 12 times in tapping hole gap, and production direct motion and equipment, personal security to whole steel mill generate
Larger threat.
The content of the invention
The purpose of this utility model is to provide a kind of improved converter taphole, when can either effectively reduce effective sintering
Between, easily sintering, and can enough improve the service life of tapping hole, reduce the occurrence probability of bleed-out accident during use, stable
The efficiency of converter.
The purpose of this utility model is achieved in that a kind of improved converter taphole, including tapping hole body, tapping
Mouthful body is more than top bore of the tapping hole body close to stove inwall close to the bottom bore of furnace outer wall, tapping hole it is intrinsic go out
The intraoral wall of steel is less than or equal to 5.7 degree in cone, tapping hole inwall taper.
When changing, any change does not occur newly-designed tapping hole for whole work flow.It is during installation, section is less
One end is in stove, and the big one end of section is on the outside of body of heater.When carrying out filling out filling using gunning refractory, front and rear phase gunning refractory pours into
Flow can keep stablizing constant, change quick, safety.The design can effectively solve tapping hole and be difficult on the outside of body of heater
The problem of filling is real, Even Sintering, while the safe to use of tapping hole can be ensured, improve the replacing efficiency of tapping hole.
Brief description of the drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is main structure diagram of the present utility model.
Embodiment
A kind of improved converter taphole, as shown in figure 1, including tapping hole body 1, tapping hole body 1 is close to furnace outer wall
Bottom bore be more than tapping hole body close to the top bore of stove inwall, the intrinsic inwall of tapping hole 2 of tapping hole is in circular cone
Shape, the inwall taper of tapping hole 2 are less than or equal to 5.7 degree.
Claims (1)
1. a kind of improved converter taphole, including tapping hole body, it is characterized in that：Tapping hole body is close to the bottom of furnace outer wall
Bore is more than top bore of the tapping hole body close to stove inwall, and the intrinsic tapping hole inwall of tapping hole is in cone, tapping
Intraoral wall taper is less than or equal to 5.7 degree.
