Abstract
The utility model belongs to a tool for maintaining tapping holes of steel converters, and particularly relates to a special tool for cleaning tapping holes. The tool comprises a steel pipe extending out of a tapping hole, wherein the steel pipe extending out of the tapping hole is formed by a galvanized steel pipe, the diameter of the steel pipe extending out of the tapping hole is 8 cm, and the length is 5.5 m -6.5 m long, the end of one side of the steel pipe extending out of the tapping hole is sheathed with a casing pipe with the diameter of 12 cm, and the casing pipe is 18 cm-22 cm long. The tool provided by the utility model has advantages of simple and reasonable structure, convenience in use and low manufacturing cost. The tool has enough strength at high temperature, and is capable of cleaning residues of the tapping hole in time, reducing the labour intensity of extending out of the tapping hole, and enhancing the operability of a converter.
Description
Technical field
The utility model belongs to the instrument of safeguarding steel tapping hole for steel making converter, particularly a kind of tap hole cleaning special tool.
Background technology
The at present complete rear employing of 120t converter tapping, the steel pipe of diameter 3cm is disclosed the tap hole operation, in this process due to tap hole in large, the tap hole of scum rod quality temperature high, make the very fast temperature distortion of steel pipe, cause tap hole to stop up, and labour intensity is large, setup time is long.
Another kind method is: adopt oxygen hose to purge in the tapping scale removal process, accumulated slag, foreign matter in tap hole are cleared up, there is potential safety hazard in oxygen blow, and easily with the inner scaling loss of tap hole.
Summary of the invention
The purpose of this utility model is to provide a kind of tap hole cleaning special tool, and it is simple and reasonable, and is easy to use, cost of manufacture is low, and enough intensity is arranged under hot conditions, can in time clear up the accumulated slag foreign matter of tap hole, reduce the labour intensity of disclosing tap hole, improve the converter operating rate.
The purpose of this utility model is achieved in that a kind of tap hole cleaning special tool, comprise and disclose the tap hole steel pipe, disclosing the tap hole steel pipe is made of galvanized steel pipe, the diameter of disclosing the tap hole steel pipe is 8cm, length is 5.5m-6.5m, be set with in the end of disclosing tap hole steel pipe one side the sleeve pipe that diameter is 12cm, the length of sleeve pipe is 18cm-22cm.
According to the requirement of converter current tap hole service procedure, converter must be cleared up tap hole after tapping is complete, and is ready for lower stove steel, avoids tap hole to stop up.Must complete in finite time for above work, guarantee that not only scum rod can be disclosed out smoothly but also must guarantee that in tap hole, foreign stops up.We have carried out design optimization by the cleaning characteristics of above tap hole to disclosing the tap hole instrument.At first the utility model improves material, and next installs the cleaning sleeve additional.
At first change material to disclosing the tap hole rod, selecting galvanized steel pipe length requirement 5.5m-6.5m of diameter 8cm, more than length can be disclosed steel inlet-outlet mouth 150cm.And then 18-22cm place, galvanized steel pipe end installs the sleeve pipe of diameter 12cm additional, and material still adopts galvanized steel pipe.Adopt galvanized steel pipe effectively reduce the labour intensity of disclosing tap hole and at high temperature have enough intensity can not bend very soon, the sleeve of end can be cleared up by the accumulated slag foreign matter tap hole to greatest extent, finally can disclose out scum rod.
This cleaning tap hole special tool through test in place, has satisfied the processing requirement that converter is produced fully.Improved production efficiency, reduced the occurrence frequency of security incident, reduced production cost, adaptation is applied.And simple and reasonable, the complete processing accuracy requirement is low, manufacturing conditions is not high, utilize the existing steel pipe in our factory, can complete low-cost production, reduce the maintenance of equipment cost, make simple to operate safe and reliable, satisfy on-the-spot service requirements, need not maintenance, do not produce the equipment purchase expense yet, have higher practical value.The utility model is simple and reasonable, and is easy to use, and cost of manufacture is low, and enough intensity is arranged under hot conditions, guarantees the accumulated slag foreign matter of cleaning tap hole, reduced the labour intensity of disclosing tap hole, improved the converter operating rate.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing, and Fig. 1 is the utility model peace structural representation.
