Abstract
The utility model discloses a repair converter tapping hole instrument fast, including the template pipe, the last lower extreme of managing in the template is equipped with the link respectively and keeps off the pipe, the diameter of template pipe slightly is greater than tapping oral siphon brick internal diameter, and the diameter of pipe slightly is lighter than tapping oral siphon brick internal diameter. The utility model discloses an essence is the high temperature that utilizes in the converter to template pipe is the base plate, carries out the sintering again to tapping hole and furnace body connected department damaged position and moulds the type, under the prerequisite of not changing whole tapping hole, just damages with the part of stove junction the tapping hole and repairs, makes tapping article increased longevity 50 -200, thus the reduction waste, reduction in production cost.
Description
One, technical field
The utility model belongs to metallurgical technology field, is specifically related to a kind of Rapid-Repair converter taphole instrument.
Two, background technology
Converter taphole is that molten steel enters unique passage of ladle by converter.During tapping, bear high-temperature molten steel, the friction of slag washes away and oxidative attack, tap hole needs constantly to repair and change, thus not only can affect the production cycle, and has influence on steel quality and production stability.
At present, steel tapping hole replacement program first uses staving press to clean out tap hole nubbin, then integral tap-hole pipe brick (circular refractory brick is bonding forms by more piece) is put into the brick cup cleared up, with refractory brick, steel-tapping hole tube brick is fixed on brick cup central position, refractory mortar shutoff is used in outside, is set level by body of heater, drops into stopping composition between brick cup external diameter and cover brick internal diameter, sinter and complete for 20 minutes, each steel tapping hole replacement time approximately needs 40-60 minute.In practical work process, just there is partial destruction in tap hole and stove junction sometimes, and other parts can also use.If now changed whole tap hole, great waste will certainly be caused, increase production cost.Need not change whole tap hole, just repairing the partial destruction of tap hole and stove junction, is current problem demanding prompt solution.
Three, summary of the invention
The purpose of this utility model is to provide a kind of Rapid-Repair converter taphole instrument, adopt this instrument can change whole tap hole, just the partial destruction of tap hole and stove junction is repaired, the tapping product life-span is improved 50-200 time, thus cut the waste, reduce production cost.
For achieving the above object, the technical solution adopted in the utility model is: this instrument comprises template pipe, is respectively equipped with link and gear pipe at the upper and lower ends of template pipe; The diameter of template pipe is slightly larger than steel-tapping hole tube brick internal diameter, and the diameter of conduit is slightly less than steel-tapping hole tube brick internal diameter.
Essence of the present utility model is the high temperature utilized in converter, with template pipe for substrate, sintering plastotype is re-started to tap hole and body of heater junction damaged part, under the prerequisite not changing whole tap hole, just the partial destruction of tap hole and stove junction is repaired, the tapping product life-span is improved 50-200 time, thus cuts the waste, reduce production cost.
Four, accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state figure of the present utility model.
Five, embodiment
As shown in the figure, the utility model comprises template pipe 1, is respectively equipped with link 3 and gear pipe 2 at the upper and lower ends of template pipe 1.The diameter of template pipe 1 slightly larger than tap hole 6 pipe brick 7 internal diameter, large about 10mm.The diameter of gear pipe 2 is slightly less than tap hole 6 pipe brick 7 internal diameter, little about 20mm.Template pipe 1 length is 400-500mm, 200mm more than longer than every pipe joint brick 7.Gear pipe 2 length is 200-300mm.
The utility model use procedure is: by residue evacuation in converter 5 stove, body of heater shakes to tapping side, maintenance level, hangs link 3 with push or pull trip 4 and this instrument is delivered to tap hole and body of heater junction damaged part 8 from converter 5 inner chamber, ajusts to set level making template pipe 1 near broken part.Then fast in the space between damaged part and template pipe 1, drop into repair material, utilizing furnace high-temperature to sinter 10-15 minute can produce in shove charge.Template pipe 1 diameter, slightly larger than tap hole 6 pipe brick 7 internal diameter, is to prevent the repair material dropped into from flowing out between template pipe 1 and tap hole 6 pipe brick 7.The diameter of gear pipe 2 is slightly less than tap hole 6 pipe brick 7 internal diameter, for the ease of inserting tap hole and body of heater junction 8, gap between itself and tap hole 6 pipe brick 7 can repaired material greasy live, even if there is repair material to flow out between template pipe 1 and tap hole 6 pipe brick 7, also can play secondary stop effect.
Above-mentioned template pipe 1 and gear pipe 2 adopt waste and old oxygen gun barrel.Above-mentioned repair material can be hand and throws self-flowing material or Gunning refractory.
