Description
Technical field
The utility model belongs to the improvement of the fastener structure of steel mill steel ladle opening brick, particularly a kind of improved steel
The fastener of bag mouth brick.
Background technology
Ladle is a kind of container utensil of high-temp liquid, and its inside is typically formed using magnesium carbonaceous ladle brick masonry, due to
Magnesia carbon brick has certain coefficient of expansion at high operating temperatures, thus ladle build by laying bricks or stones terminate it is latter as pressure brick is carried out to bag mouth brick
To ensure that squeezed tight is seamless between magnesia carbon brick, then enclosed in bag mouth one and smear castable, avoid ladle molten steel when toppling over
The press strip of steel ladle opening is washed out, causes ladle magnesia carbon brick integrally to produce circumferential weld, original press strip work flow is by many bars
Shape steel plate is welded on steel ladle opening inner edge, then in one layer of relatively thin castable of surface smear, but as ladle is accepted repeatedly
After molten steel and bold and vigorous slag sprinkle molten steel, surface casting material is washed totally, and bag mouth press strip is also washed out, and does not have the effect of pressure brick, and
It is disposable to press the steel plate used in brick, so bag mouth press strip is embedded in castable makes it not washed away by molten steel to be
Need to solve the problems, such as at present.
Utility model content
The purpose of this utility model is to provide a kind of fastener of improved steel ladle opening brick, and its is rational in infrastructure, into
This low, multiple utilization, pressure brick effect are good, can improve bag mouth castable service life, lift ladle safety guarantee.
What the purpose of this utility model was realized in：A kind of fastener of improved steel ladle opening brick, is included in steel
Permanent refractory material layer is set on the inwall of Baogang's shell, bag mouth brick is uniformly arranged in permanent refractory material layer, positioned at bag
Uniform affixed the horizontal press strip of rectangle, the short side end face of press strip one end are fixed on the ladle box hat annular inner wall on mouthful brick top
On the inwall of ladle box hat, the bottom surface of press strip is engaged with the top surface of bag mouth brick, and 300mm is smaller than between adjacent press strip,
The length of press strip is 200mm, thickness 300mm, width 50mm, and bag mouth brick grows the outer face of press strip, is being uniformly arranged pressure
The bag mouth bed of material is set on the bag mouth brick top surface of bar.
Main contents are as follows：
First, a length of 200mm of polylith, thickness 30mm, width 50mm long strip type press strip vertical position welding are taken in steel ladle opening steel
Plate interior edge.Concrete operation method：Steel ladle opening brick builds by laying end, and the longer leptoprosopy of strip-shaped steel plate is close into refractory brick surface, shorter
Leptoprosopy is close to steel ladle opening interior edge steel plate, and press strip is intraoral along steel plate progress full weld with wrapping, and mouth will be wrapped by reusing same procedure
Turn around uniform welding identical press strip, and the spacing of every piece of press strip is no more than 300mm, after the completion of using bag mouth mold tool by bag mouth material
It is covered on press strip and smashes tight tamping.
Improvement effect
1st, press strip is embedded in castable, and molten steel can not contact or be washed into press strip, and press strip is repeatable to be utilized；
2nd, press strip space-consuming is few, and castable smearing thickness increase, the service life of bag mouth castable extends；
It is 3rd, increasingly tighter between brickwork joint after magnesia carbon brick expansion by the reaction force of this firm bag mouth press strip,
Ladle will not produce circumferential weld, and ladle is protected safely.
The utility model is rational in infrastructure, cost is low, it is multiple utilize, pressure brick effect it is good, improve bag mouth castable and use the longevity
Life, improves ladle safety guarantee.
Brief description of the drawings
The utility model is further described below in conjunction with accompanying drawing, Fig. 1 illustrates for the utility model sectional structure
Figure, Fig. 2 are the overlooking the structure diagram that Fig. 1 removes the switch mouth bed of material.
Embodiment
A kind of fastener of improved steel ladle opening brick, as shown in Figure 1 and Figure 2, is included on the inwall of ladle box hat 1
Permanent refractory material layer 2 is set, bag mouth brick 3 is uniformly arranged in permanent refractory material layer 2, positioned at the top of bag mouth brick 3
Uniform affixed the horizontal press strip 4 of rectangle, the short side end face of the one end of press strip 4 are fixed in ladle steel on the annular inner wall of ladle box hat 1
On the inwall of shell 1, the bottom surface of press strip 4 is engaged with the top surface of bag mouth brick 3, and 300mm, pressure are smaller than between adjacent press strip 4
The length of bar 4 is 200mm, thickness 300mm, width 50mm, and bag mouth brick 3 grows the outer face of press strip 4, is being uniformly arranged pressure
The bag mouth bed of material 5 is set on the top surface of bag mouth brick 3 of bar 4.The thickness of the bag mouth bed of material 5 is 30-50mm.
