Description
Technical field
This utility model is related to metallurgical technology field, specifically a kind of tank ladle.
Background technology
The Molten Iron Transportation of big-and-middle-sized steel plant, generally using the organization of production of blast furnace → torpedo tank car → ladle → converter
Pattern.Although this kind of pattern has many advantages, such as mobility is good, hot metal temperature drop is little, while having molten iron pretreatment, adjustment
The function such as molten iron temperature and composition and buffering, but, the high benefit pursued with modern metallurgical technology, the target phase of low energy consumption
Than still there is certain gap.It is mainly manifested in, Molten Iron Transportation link is more, production efficiency is relatively low, high energy consumption, three de- effects are poor, one
The aspect such as the investment of secondary property is big, operating cost is higher.In order to overcome the problems referred to above, it is many that some iron and steel corporations employ ladle
Function micronizing technology, i.e., one bag is on earth.One wraps on earth, i.e., using a kind of access for possessing molten iron, transport, buffer reservoir, ferrum
Water pretreatment, converter iron making and hot-metal insulating etc. are multi-functional to contain ferrum container-ladle, and blast furnace molten iron out is being passed through
After necessary technological process is processed, to be changed without the production organization mode of the ladle, directly be blended in converter and smelt, the metallurgy flows
Technical process be referred to as " one bag on earth " Molten Iron Transportation technology, referred to as " a tank system ".
Although a tank Technology has advantage, but many negative effects are brought to refractory material.With torpedo
Tank refractory material is compared, and a tank ladle refractory material is more easily damaged, and the life-span is relatively low.Ladle carries out desulfurization typically using spray
Blow desulphurization and KR stirring desulphurizations, sweetening process can introduce large quantities of lime, fluorite, granule magnesium powder etc., and especially slag line position is corroded
Seriously.Meanwhile, the when of falling molten iron bag mouth similarly bear and wash away erosion from molten iron and slag, as a tank ladle is used
Life-time dilatation, with colding and heat succeed each other repeatedly, bag mouth is using castable and the slag line Al of its seam crossing2O3- SiC-C brick heat is swollen
The difference of swollen coefficient, causes seam crossing transverse joint increasing, seam crossing stress concentration, accelerates the damage of operational layer brick and bag mouth material
Ruin, cause to stitch increasing slag iron constantly penetrating in transverse joint, cause large area shim between slag line working lining and permanent layer, give
The safe operation of ladle brings great hidden danger, once there is the accident of leakage ferrum, consequence will be hardly imaginable.At the same time,
In order to avoid there are the problems referred to above, the general renovation method for changing bag mouth for adopting carries out light maintenance, although so reducing Lou ferrum thing
Therefore probability of happening, but can so improve the holistic cost of ladle, it is often more important that with the increase of light maintenance number of times, lead
Cause ladle to cold and heat succeed each other repeatedly, affect the service life of material.
Utility model content
In order to make up, the above is not enough, and this utility model provides the high tank ferrum of a kind of long service life, safety coefficient
Water bag, to solve the problems, such as in above-mentioned background technology.
The technical solution of the utility model is：
An a kind of tank ladle, including inclusion, bag mouth and the slag line in inclusion, the slag line protrusion are arranged on bag
The middle part of body, the upper end of slag line are extended to below bag mouth, connect course between the slag line and bag mouth, and the course includes outer layer
And internal layer, the outer layer is flat course, and the internal layer is laid on end layer.
Used as preferred technical scheme, the upper end of the course is connected to bag mouth and inclusion junction, the connection of course lower end
In the upper end of slag line.
Used as preferred technical scheme, the course is connected with inclusion from the upper end of the slag line positioned at middle part towards both sides bag mouth
Meet place to extend.
As preferred technical scheme, upper end of the internal layer upper end higher than outer layer.
Used as preferred technical scheme, laid on end seam and the flat puzzle joint of outer layer of the internal layer are crisscross arranged.
As a result of above-mentioned technical proposal, a kind of tank ladle described in the utility model by improve slag line with
The masonry construction of Bao Zui junctions, not only avoid the generation that shim oozes ferrum accident, and also reduce the cost of refractory material,
The most important production for being to ensure a tank ladle safety and stability.
