Abstract
The utility model provides a converter steel-tapping hole sleeve pipe, the steel-tapping hole sleeve pipe is the wedge pipe that one end is thick, the other end is thin, and the internal orifice external diameter of sleeve pipe is reduced 10% ~ 13% than the external orifice external diameter, forms the little, the big wedge steel-tapping hole sleeve pipe of external orifice external diameter of internal orifice external diameter. The utility model discloses can save the sleeve pipe change time, prolong tapping hole life, reduce the change cycle, increase tapping time 4 ~ 5 minutes's heat simultaneously, reduce later stage tapping hole and take the sediment volume, improve the converter productivity.
Description
Technical Field
The utility model belongs to the field of steelmaking equipment, especially, relate to a wedge converter tapping hole sleeve pipe.
Background
The converter steel tapping hole needs to be replaced periodically according to the service life, and in the operation of replacing the steel tapping hole, because the drill bit of the converter dismantling machine is conical, the diameter of the inner hole after drilling is small, residual steel exists at the position, a sleeve cannot be inserted, oxygen burning operation is needed, the labor intensity is high, the operation danger is caused, the production rhythm is influenced, and the time is consumed.
Disclosure of Invention
The utility model aims to provide a converter steel-tapping hole sleeve pipe which can shorten the replacement time of the steel-tapping hole sleeve pipe, stop oxygen burning operation and prolong the service life of the steel-tapping hole.
Therefore, the utility model discloses the technical solution who takes does:
a steel-tapping hole sleeve of a converter is a wedge-shaped pipe with one thick end and the other thin end, and the outer diameter of a lining hole of the sleeve is reduced by 10% -13% compared with the outer diameter of an outer hole to form the wedge-shaped steel-tapping hole sleeve with a small inner hole diameter and a large outer hole diameter.
The utility model has the advantages that:
due to the adoption of the wedge-shaped steel-tapping hole sleeve, the sleeve can be directly inserted without continuing reaming and oxygen burning operation after the original steel-tapping hole is drilled, so that the replacement time is saved; because the external diameter of the inner opening of the sleeve is reduced, the usage amount of the Martin sand gunning material needs to be increased, compared with a cylindrical sleeve, the magnesium content of the inner opening is increased, and the gunning material around the inner opening is tamped, so that the service life of the steel tapping opening can be prolonged, the replacement period is shortened, the heat of the steel tapping time is increased by 4-5 minutes, the slag quantity of the steel tapping opening in the later period is reduced, and the productivity of the converter is improved.
Drawings
FIG. 1 is a front view of a tapping hole sleeve of a converter;
FIG. 2 is a left side view of the tapping hole sleeve of the converter.
In the figure: a sleeve outer hole 1, a steel tapping hole sleeve 2 and a sleeve inner hole 3.
Detailed Description
As can be seen from the attached drawing, the utility model discloses converter steel-tapping hole sleeve pipe 2 changes the sleeve pipe of former cylinder shape into wedge steel-tapping hole sleeve pipe 2 that one end is thick, the other end is thin, keeps the external diameter of former cylinder shape sleeve pipe outer mouthful 1 unchangeable promptly, reduces 10% ~ 13% with the external diameter of mouthful 3 in the sleeve pipe, forms a little, the big wedge steel-tapping hole sleeve pipe 2 of outer mouthful external diameter of mouthful external diameter in the interior external diameter of mouthful.
The embodiment is that the outer diameter of the outer casing opening 1 of the cylindrical casing with the diameter of 330mm is kept constant, and the outer diameter of the inner casing opening 3 is reduced by 40mm, thereby forming a wedge-shaped steel-outlet casing 2 with the outer diameter of 330mm of the outer casing opening 1 and the outer diameter of 290mm of the inner casing opening 3.
Claims (1)
1. The converter steel-tapping hole sleeve is characterized in that the steel-tapping hole sleeve is a wedge-shaped pipe with one thick end and the other thin end, and the outer diameter of an inner hole of the sleeve is reduced by 10% -13% compared with the outer diameter of an outer hole to form the wedge-shaped steel-tapping hole sleeve with a small inner hole outer diameter and a large outer hole outer diameter.
