Abstract
The utility model provides an online straightener of converter sublance, belongs to metallurgical equipment technical field, and its technical scheme is, and including base, jack and cover two U type bolts on the converter sublance rifle body in the constitution, the head of two U type bolts passes screw in nut behind the bolt hole at base both ends respectively, the jack is placed between the rifle body of the middle part of base and converter sublance. The utility model discloses utilize the thrust of jack to align the rifle body of converter sublance, avoided trading for a long time the influence that the rifle caused to the smelting cycle to guarantee the normal operating of converter, reduced the brick -lined harm of stove, reduced the steelmaking cost.
Description
Technical field
This utility model relates to a kind of device that diastrophic revolving furnace sublance gun body can carry out on-line straightening, belongs to technical field of metallurgical equipment.
Background technology
Revolving furnace sublance is the necessary component of modern steelmaking converter, its major function be do not fall molten steel is sampled in the case of stove, thermometric.In actual production process, frequently passing in and out burner hearth due to sublance, its gun body rifle head section is easy to produce flexural deformation because of cold and hot STRESS VARIATION, causes automatically loading and cannot realizing of probe.And change sublance typically need to be with two hours, the period converter manual sampling of falling stove thermometric, not only increase labor intensity, extend smelting cycle, the most fragile backup lining brick.
Utility model content
The purpose of this utility model is the drawback for prior art, it is provided that a kind of revolving furnace sublance on-line straightening device, the sublance deformed with quick reparation, it is ensured that converter is properly functioning, reduces smelting cost.
Problem described in the utility model realizes with following technical proposals:
A kind of revolving furnace sublance on-line straightening device, composition includes base, jack and two U-bolts being enclosed within revolving furnace sublance gun body, the head of two U-bolts screws in nut after being each passed through the bolt hole at base two ends, and described jack is placed between the middle part of base and the gun body of revolving furnace sublance.
Above-mentioned revolving furnace sublance on-line straightening device, also includes in composition compressing backing plate, and the gun body of revolving furnace sublance is pressed in the curved bend of this U-bolt by described compression backing plate by two nuts on a U-bolt.
Above-mentioned revolving furnace sublance on-line straightening device, is equipped with protection backing plate between described jack and the gun body of revolving furnace sublance, between each U-bolt and the gun body of revolving furnace sublance.
Above-mentioned revolving furnace sublance on-line straightening device, described base is plate body, which is provided with the reinforcement gusset plate being parallel to gun body.
This utility model utilizes the thrust of jack the gun body of revolving furnace sublance to be aligned, it is to avoid change the impact that smelting cycle is caused by rifle for a long time, thus ensure that the properly functioning of converter, decreases the infringement to backup lining brick, reduces steel-making cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is the top view of Fig. 1.
In figure, each list of reference numerals is: 1, sublance body, 2, base, 3, strengthen gusset, 4, jack, 5, protection backing plate, 6, compress backing plate, 7, U-bolt.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, this utility model mainly includes base 2, jack 4, protection backing plate 5, compresses backing plate 6 and two double end U-bolts 7.Wherein, base 2 uses the steel plate of Q235B δ=16mm to make, and on it, gusset 3 is strengthened in welding, and manufactures the bolt hole of 4 Ф 22mm.The model of two double end U-bolts 7 is M20, total length 1000mm, and the two sections of reaches installing the U-bolt compressing backing plate 6 are 450mm, and two sections of each 100mm of reach of another U-bolt, bolt go-and-retum is away from being 118mm.Screw jack 4 model is 5T.Protection backing plate 5 is made by the cutting of Ф 133 δ 10mm seamless steel pipe, chord length 110mm.Compress backing plate 6 to be made by the cutting of Q235B δ 10mm steel plate.
Strengthen gusset 3 to be welded on base 2 to strengthen its bending strength.First it is fixed in gun body with compression 6 U-bolts of backing plate and a protection backing plate 5 during use; again base 2 is installed on this U-bolt; then another U-bolt and residue protection backing plate 5 are installed; finally jack 4 is placed between gun body and base; operation jack extruding gun body, reaches to align purpose.
