Embodiment
As shown in Figure 1, this converter taphole sleeve brick mainly comprises internal segment brick 1, middle joint brick 2, the acromere brick 3 that end face docks successively.Wherein, middle joint brick 2 is provided with some joints.
Internal segment brick 1, middle joint brick 2 are the cylindric and inner cylindrical hole that is provided with vertically.The internal diameter of internal segment brick 1 equates that with the internal diameter of middle joint brick 2 external diameter of internal segment brick 1 also equates with the external diameter of middle joint brick 2.
Acromere brick 3 is provided with cylindrical hole vertically for truncated cone-shaped and inside; The internal diameter of acromere brick 3 equates with the internal diameter of middle joint brick 2; The diameter of the inner face 31 of acromere brick equates that with the external diameter of middle joint brick 2 diameter of the outer face 32 of acromere brick is greater than the diameter of inner face 31 and greater than tap hole brick cup 7 round mouth diameters.The length that exposes outside tap hole brick cup 7 behind acromere brick 3 insertion tap hole brick cups 7 round mouths is 50～200mm, can in tapping process, play the protection to tap hole brick cup 7 and converter shell.
Internal segment brick 1, middle joint brick 2, acromere brick 3 are set on the steel pipe 5 through its through hole separately successively.Be fixed with outward flange dish 6, inner flange 4 on the steel pipe 5, outward flange dish 6 and steel pipe 5 vertical welding, inner flange 4 welds or is threaded on the steel pipe 5.Outward flange dish 6 is positioned at the outside of acromere brick 3, and inner flange 4 is positioned at the inboard of internal segment brick 1, and two ring flanges are with internal segment brick 1, middle joint brick 2, acromere brick 3 axial compression.
The outer end of steel pipe 5 grows 20～50mm in the outer face of acromere brick 3; The inner of steel pipe 5 grows the inner face 200～500mm in internal segment brick 1.Prevent that whole sleeve brick from packing into behind the tap hole brick cup 7, between sleeve brick and tap hole brick cup 7, get into during slit pouring refractory matter in the tapping passage (internal segment brick, the through hole of joint brick, acromere brick constitute the tapping passage) from fire door.
The outer face of internal segment brick 1 cooperates with the boss rim of the mouth through recessed female mouthful between the inner face of adjacent middle joint brick 2 and is plugged on.Be plugged on the cooperation of boss rim of the mouth through recessed female mouth between the end face of two adjacent middle joint bricks 2.The inner face of acromere brick 3 cooperates with the boss rim of the mouth through recessed female mouthful between the outer face of adjacent middle joint brick 2 and is plugged on.
As shown in Figure 3, the inner face 11 of internal segment brick is a circular planes, and the outer face 12 of internal segment brick is provided with boss rim of the mouth 13.As shown in Figure 4, the inner face 21 of middle joint brick is provided with recessed female mouthful 24, and the outer face 22 of middle joint brick is provided with boss rim of the mouth 23.As shown in Figure 5, the inner face 31 of acromere brick is provided with recessed female mouthful 33, and the outer face 32 of acromere brick is a circular planes.Like this, the molten steel direction of trickling was consistent when female mouthful direction was inserted in the boss rim of the mouth with tapping, and molten steel is not excessive in the tapping process.
During manufacturing; Earlier outward flange dish 6 vertical welds are connected to an end of steel pipe 5,, hold up steel pipe 5 during assembling apart from 20～50mm of steel pipe; The truncated cone-shaped of packing into acromere brick 3; Joint brick 2 in one is installed on the steel pipe 5, and female mouthful of place of the boss rim of the mouth of joint brick, acromere brick 3 is coated with fire-resistant wedding agent and both bondd in this, injection refractory powder and tamping in the slit between steel pipe 5 and acromere brick, the middle joint brick; By above step with all some in joint bricks 2 be nested with successively on the steel pipe 5 and be plugged on successively with internal segment brick 1; Refractory powder tamps, and inner flange 4 is installed to make on the steel pipe 5 between internal segment brick 1, middle joint brick 2, the acromere brick 3 behind the jam-packed again, with inner flange 4 welding or be screwed on the steel pipe 5; Whole sleeve brick assembling is accomplished.
As shown in Figure 2; When on-the-spot whole sleeve brick is changed with it from the stokehold is packed tap hole brick cup 7 into; Because acromere brick 3 is that round platform and outer face diameter are greater than tap hole brick cup 7 round mouth diameters; So whole sleeve brick is stuck on the tap hole brick cup 7, can not come off, the acromere brick exposes steel pipe and welds with fixing sleeve brick through the mounting flange on ironware and the converter taphole shell; Shake the stove of flatting turn then, from fire door being sprayed or water closely knit fixing whole sleeve brick with refractory clay 8 in slit between sleeve brick and the brick cup then gets final product.
So only need the once-cast refractory clay can accomplish sleeve brick and fix, simple to operate, save time.
