Abstract
The utility model relates to an improvement on structures of discharging chutes of both a steel-making converter and a refining furnace, in particular to an improved discharging chute of a converter. The improved discharging chute of the converter comprises a discharging chute which is connected to the outlet of a discharging pipe, wherein a semicircular installing through slot axially penetrating through the discharging chute is formed at a junction of the discharging pipe and the discharging chute and on a seam of the lower semicircular interface of the discharging chute; the external diameter of the semicircular installing through slot is equal to the internal diameter of the discharging chute; a discharging liner plate with a baffle plate at the tail end is matched with and installed inside the installing through slot; and the cross section of the discharging liner plate is a semicircular arc surface. The service life of the discharging chute can be prolonged; failures of the discharging chute can be reduced; the time for replacing the discharging chute can be shortened; the consumption of maintenance manpower and maintenance materials is reduced; and the operating rate of a metallurgical furnace can be improved.
Description
Technical field
The utility model belongs to the improvement of steelmaking converter and refining furnace emission of baiting chute structure, particularly a kind of improved converter emission of baiting chute.
Background technology
Alloy and auxiliary material all need to join in the body of heater or in the steel ladle through emission of baiting chute in converter production process.
Traditional emission of baiting chute and weighing bucket are an integral body.Under the continuous impact of auxiliary material and alloy, emission of baiting chute wearing and tearing especially severe causes the converter hourglass material that feeds in raw material; If change, must the integral replacing tremie pipe, like integral replacing not, then need mend broken parts by replacing a damaged part welding, cause the activity duration long like this, the cost height.Tradition emission of baiting chute drawback has seriously restricted the performance and the expansion of our factory production capacity.
Tradition emission of baiting chute easy abrasion generally need have only about one month and just need mend by replacing a damaged part;
Need 2 people to carry out work compound when emission of baiting chute is mended by replacing a damaged part, operating environment is abominable: belong to heavy coal gas, dust zone, work high above the ground.
Operation process is following: will excavate eroded area earlier, fill up the piece making according to excavating size again; To fill up piece and emission of baiting chute then and carry out full weld.Whole process need 2 hours;
The online life cycle of following pipe of emission of baiting chute is generally about 4 months.Change minimum needs 5 people of emission of baiting chute and carry out work compound.Higher because of the emission of baiting chute installation site, big (2-3 rice) heavier (the about 600KG) of bulk volume needs two chain blocks to lift by crane simultaneously, cooperatively interacts and has bad luck, activity duration 3-4 hour.
Summary of the invention
The purpose of the utility model is to provide a kind of improved converter emission of baiting chute; Can prolong the service life of emission of baiting chute, reduce the fault of emission of baiting chute, shorten the activity duration that emission of baiting chute is changed; Reduce the consumption of safeguarding the man power and material, improve the Homes Using TV of metallurgical furnace.
The purpose of the utility model is achieved in that a kind of improved converter emission of baiting chute; Be included in the tremie pipe outlet and go up the emission of baiting chute that connects; Be positioned at tremie pipe and emission of baiting chute interface and on the lower half circle interface seam of emission of baiting chute the semicircle that axially feeds emission of baiting chute be set groove is installed; The semicircle external diameter that groove is installed equates with the internal diameter of emission of baiting chute; In groove is installed, cooperate the baffled blanking liner plate of tail end is installed, the shape of cross section of blanking liner plate is the liner plate of semicircle arc surfaced.
Because the utility model is positioned at tremie pipe and emission of baiting chute interface on the lower half circle seam of emission of baiting chute the semicircle installation groove that axially feeds emission of baiting chute is being set;, groove cooperates the semicircle arc surfaced blanking liner plate of installing in being installed; Its external diameter equates that with the internal diameter of emission of baiting chute the outer wall of the back blanking liner plate that is in place just overlaps with the emission of baiting chute inwall.When keeping in repair the emission of baiting chute of wearing and tearing, only need more casing replacing, do not have welding capacity basically.Save the processing time of changing emission of baiting chute or mending emission of baiting chute by replacing a damaged part, sleeve pipe is changed process at present only needs 2 people to cooperate, and in 30 minutes, just can accomplish, and has reduced labour intensity.Prolonged the service life of emission of baiting chute, changed at fixed cycle under the situation of blanking sleeve pipe, the tremie pipe body is accomplished basically and need not be changed.Reduce the fault rate of emission of baiting chute.This structure Design of the utility model can shorten emission of baiting chute wearing and tearing back integral replacing greatly or mend the time of welding by replacing a damaged part; Improve the Homes Using TV of converter or refining furnace; Can greatly shorten the plant maintenance time, improve the cycle utilization rate; Realizing that old and useless article utilizes again, is the precondition that realizes automatic job.
The utility model has prolonged the service life of emission of baiting chute, has reduced the fault of emission of baiting chute, has shortened the activity duration that emission of baiting chute is changed, and has reduced the consumption of safeguarding the man power and material, has improved the Homes Using TV of metallurgical furnace.

The specific embodiment
A kind of improved converter emission of baiting chute; Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; Be included in tremie pipe 1 outlet and go up the emission of baiting chute 2 that connects; Be positioned at tremie pipe 1 and emission of baiting chute 2 interfaces on the lower half circle interface seam of emission of baiting chute 2 the semicircle installation groove 5 that axially feeds emission of baiting chute 2 is being set; The semicircle external diameter that groove 5 is installed equates with the internal diameter of emission of baiting chute 2, in groove 5 is installed, cooperates the blanking liner plate 3 that tail end has baffle plate 4 is installed, and the shape of cross section of blanking liner plate 3 is the liner plate of semicircle arc surfaced.On the inwall of blanking liner plate 3, wear-resistant rubber sheet 6 is installed through screw.Being shaped as and blanking liner plate 3 concentrically ringed semicircle arc baffle plates of baffle plate 4.Factors such as the wearability of considering rubber (waste and old belt making) is better than steel, replacing is convenient.Sleeve pipe adopts rubber and steel pipe composite design, boring, tapping on steel pipe, and boring sunk screw is connected rubber with steel pipe on rubber.Substitute the wearing and tearing of welded tube with the wearing and tearing of old rubber, reduced the subsequent use quantity of emission of baiting chute.Can reduce maintenance cost.
