Abstract
The utility model belongs to steel ladle and the molten iron handbag mouth cleaning plant of steel mill use, the particularly cold steel extractor of a kind of steel ladle opening of improvement, the lower end radial equipartition of vertical arm arrange 4 tilt upward pull out steel pawl, the structure of pulling out steel pawl is the tabular tooth with acute angle crown, the angle of tabular tooth crown is 25 °-35 °, the inner toothed surface of tabular tooth and the angle of vertical hanging arm axle line are 55 °-60 °, arrange hook on hole in the upper end of vertical arm.The utility model is rational in infrastructure, when the cold steel that removing steel ladle opening is bonding, pulls out the gap that steel pawl easily enters cold steel and bag mouth, and should not come off, and practical and convenient, cleaning speed is fast, can reduce the labour intensity of workman.
Description
Technical field
The utility model belongs to steel ladle and the cold steel extractor of molten iron handbag mouth cleaning plant, particularly a kind of steel ladle opening of improvement of steel mill use.
Background technology
Ladle has watered at converter tapping process, refining process and continuous casting all can at the bonding cold steel of steel ladle opening when molten steel falls to note remaining, follow-up refining can be affected when the bonding volume of cold steel is larger, cause refining furnace clad cannot cover on bag mouth, can fall down if cold steel is subject to External Force Acting, potential safety hazard is caused to ladle surrounding devices or personnel.Therefore, steel ladle opening needs to clear up in time, and at present, the most effective way uses crane to sling to use the cold steel extractor of Plate Welding or riveted joint to be removed by cold for bag mouth steel.Steel mill steel ladle opening cold steel clean-up process is: crane is sling cold steel extractor, aims at cold steel and pulls out, can proceed normal operation after steel ladle opening cleans out.Pulling out bottom steel pawl of former cold steel extractor is comparatively mild, and top for arranging in the outer end of horizontal boom, head is not sharp, therefore when pulling out the cold steel of bag mouth, cold steel is easy to obscission occurs, and increase cold steel clearance time, worker's labour intensity is larger.The subject matter existed is as follows: 1, pull out bottom steel pawl comparatively mild, head is not sharp, and therefore when pulling out the cold steel of bag mouth, cold steel is easy to obscission occurs.2, pull out steel pawl away from the center of gravity of cold steel extractor, bad stressed when therefore clearing up cold steel, cleaning effect is poor.3, need artificial multi-pass operation, labor strength is larger.
Summary of the invention
The purpose of this utility model is to provide a kind of steel ladle opening of improvement cold steel extractor, and it is rational in infrastructure, when the cold steel that removing steel ladle opening is bonding, pull out the gap that steel pawl easily enters cold steel and bag mouth, and should not come off, practical and convenient, cleaning speed is fast, can reduce the labour intensity of workman.
The purpose of this utility model is achieved in that the cold steel extractor of a kind of steel ladle opening of improvement, the lower end radial equipartition of vertical arm arrange 4 tilt upward pull out steel pawl, the structure of pulling out steel pawl is the tabular tooth with acute angle crown, the angle of tabular tooth crown is 25 °-35 °, the inner toothed surface of tabular tooth and the angle of vertical hanging arm axle line are 55 °-60 °, arrange hook on hole in the upper end of vertical arm.
Cold for former bag opening steel extractor is pulled out steel pawl and transform sharp angle structure upwards as by the utility model, be 90 ° of distributions at the steel pawl that pulls out of the lower end radial equipartition of vertical arm, and the distance of steel pawl end from extractor center of gravity is pulled out in amendment, easily stressed when making the cold steel of cleaning, be not easy during cleaning to come off, cold steel cleaning speed is fast.
Pull out steel pawl end after improvement effect (1) transformation comparatively sharp, easily enter the gap of cold steel and bag mouth, easy to use, cleaning speed is fast, reduces hand labor intensity.(2) this cold steel extractor is formed by Plate Welding or riveted joint, and structure is simple, is easy to make, low cost of manufacture.The utility model is rational in infrastructure, when the cold steel that cleaning steel ladle opening is bonding, achieves the gap that steel pawl is easy to enter cold steel and bag mouth, and should not come off, and easy to use, cleaning speed is fast, reduces the labour intensity of workman.
Accompanying drawing explanation
Be further stated the utility model below in conjunction with accompanying drawing, Fig. 1 is main TV structure schematic diagram of the present utility model.
Detailed description of the invention
A kind of cold steel extractor of steel ladle opening of improvement, as shown in Figure 1, the lower end radial equipartition of vertical arm 1 arrange 4 tilt upward pull out steel pawl 2, the structure of pulling out steel pawl 2 is the tabular tooth with acute angle crown, the angle of tabular tooth crown is 25 °-35 °, the inner toothed surface of tabular tooth and the angle of vertical arm 1 axis are 55 °-60 °, arrange hook on hole 3 in the upper end of vertical arm 1.The angle of pulling out steel pawl 2 tabular tooth crown is 30 °.Pull out the inner toothed surface of steel pawl 2 tabular tooth and the angle of arm 1 axis is 60 °.
