Abstract
The utility model relates to a kind of fastening firm shaped steel bag, it is characterized in that: it comprises ladle (1), the outside of described ladle (1) is that outer ring bag is along (2), inside is ladle inner wall (3), the inside of described ladle (1) comprises bag mouth brick (5), bag mouth inserts (6) and reinforcement (4), described bag mouth brick (5) is positioned at the inner outer side of ladle (1), described bag mouth inserts (6) is positioned at the inner inner side of ladle (1), this bag mouth inserts (6) and bag mouth brick (5) connection are reinforcement (4), described reinforcement (4) oblique setting.This fastening firm shaped steel bag improves the bond strength between bag mouth brick and ladle by the lifting surface area increasing bag mouth brick, thus fastens the bag mouth of ladle, effectively prevent resistance to material and pollutes molten steel, improves ladle service life.
Description
Technical field
The utility model relates to a kind of fastening firm shaped steel bag, can prevent bag mouth brick from coming off in ladle use procedure, reduces resistance to material and pollutes molten steel probability, can extend the service life of ladle simultaneously, belong to metallurgical ladle steelmaking technical field.
Background technology
Current, in one of ladle refining technique important composition operation having become special steel field of smelting, particularly VD vacuum process, because the mixed punching of slag under vacuum state is violent, the meeting bag of ladle, along being subject to washing away of high temperature melt cinder and molten steel, there will be the sticky glutinous steel ladle opening of cold steel after broken sky; In addition, when adopting refining secondary slagging process, needing to remove primary slag from the bag mouth of ladle, in this process, also there will be cold steel and be sticky in steel ladle opening.
Produce for remaining normal and ensure steel quality, need often to process the cold steel of steel ladle edge, and pressure stripping can only be carried out by external force to the sticky glutinous cold steel of steel ladle edge at present, often because the adhesion between cold steel and bag mouth brick is greater than the bond strength of bag mouth brick and bag wall, bag mouth brick is caused to peel off together with cold steel, thus damaged the bag edge of ladle, make resistance to material enter molten steel, have impact on the safe handling of ladle.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides one can either reduce ladle and turns the probability that comes off, and improves ladle life, can not increase again the fastening firm shaped steel bag that cost built by laying bricks or stones by ladle.
The purpose of this utility model is achieved in that
The fastening firm shaped steel bag of the utility model, comprise ladle, the outside of described ladle is bag edge, outer ring, inside is ladle inner wall, the inside of described ladle comprises bag mouth brick, bag mouth inserts and reinforcement, described bag mouth brick is positioned at the inner outer side of ladle, the cross sectional shape of this bag mouth brick is made up of the rectangle of bottom and the trapezoidal of top, wherein rectangle and trapezoidal between forming station terrace, described bag mouth inserts is positioned at the inner inner side of ladle, the cross sectional shape of this bag mouth inserts is inverted trapezoidal, this bag mouth inserts and bag mouth brick connection are reinforcement, the oblique setting of described reinforcement.
The beneficial effects of the utility model are:
This fastening firm shaped steel bag improves the bond strength between bag mouth brick and ladle by the lifting surface area increasing bag mouth brick, thus fastens the bag mouth of ladle, effectively prevent resistance to material and pollutes molten steel, improves ladle service life.
Accompanying drawing explanation
Fig. 1 is the front view of the fastening firm shaped steel bag of the utility model.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the A-A sectional view of Fig. 2.
Wherein: ladle 1, outer ring bag along 2, ladle inner wall 3, reinforcement 4, bag mouth brick 5, bag mouth inserts 6.
Detailed description of the invention
See Fig. 1 and Fig. 2, the utility model relates to a kind of fastening firm shaped steel bag, comprises ladle 1, and the outside of described ladle 1 is that outer ring is wrapped along 2, and inside is ladle inner wall 3.
As Fig. 3, the inside of described ladle 1 comprises bag mouth brick 5, bag mouth inserts 6 and reinforcement 4, described bag mouth brick 5 is positioned at the inner outer side of ladle 1, the cross sectional shape of this bag mouth brick 5 is made up of the rectangle of bottom and the trapezoidal of top, wherein rectangle and trapezoidal between forming station terrace, described bag mouth inserts 6 is positioned at the inner inner side of ladle 1, the cross sectional shape of this bag mouth inserts 6 is inverted trapezoidal, this bag mouth inserts 6 is reinforcement 4 with bag mouth brick 5 connection, the oblique setting of described reinforcement 4.
This fastening firm shaped steel bag improves the bond strength between bag mouth brick and ladle by the lifting surface area increasing bag mouth brick, thus fastens the bag mouth of ladle, effectively prevent resistance to material and pollutes molten steel, improves ladle service life.
