Abstract
The utility model discloses an inner lining structure of a steel ladle, which comprises a permanent layer and a working layer, wherein the permanent layer and the working layer are integrated to form a permanent working layer; the outer side of the permanent layer is provided with a heat preservation layer. The inner lining structure of the steel ladle has the advantages of firmness, durability and safety. Besides, the utility model can shorten a maintenance construction period of a ladle and reduce use cost and maintenance cost of an integral casing inner liner of a ladle. The heat preservation layer can reduce heat conduction towards outside for molten steel, and realize low temperature steel tapping and constant temperature casting.
Description
Technical field
The utility model relates to a kind of steelmaking equipment, relates to a kind of ladle wall inner lining structure particularly.
Background technology
In existing technology, the inner lining structure of ladle is outside permanent layer and inner working lining two parts composition, Chinese patent application CN97215132 discloses a kind of " ladle integral pouring liner ", be between permanent layer and pouring layer, to build fire brick layer by laying bricks or stones, the ladle that adopts this method to build by laying bricks or stones will be removed pouring layer and fire brick layer after using specified number of times, increased working strength of workers, and long construction period, cost is higher.In recent years, big-and-middle-sized ladle liner both domestic and external adopts integrated poured structure, and this integral cast structure is made up of the permanent layer and the inner working lining of outside, its have labor productivity height, integrated cost low, to characteristics such as the molten steel pollution are little.But from aspects such as the baking of ladle, use, repairings, ladle still needs working lining is removed when using certain bag number of times in age, casting again, refractory consumption rate is bigger, use and maintenance cost than higher.
The utility model content
The purpose of this utility model is at the problems referred to above, and a kind of ladle wall inner lining structure is provided, and it is sturdy and durable, and security is good, can shorten the ladle maintenance construction cycle, reduces the use cost and the maintenance cost of ladle integral pouring liner.
For achieving the above object, the technical solution of the utility model is: a kind of ladle wall inner lining structure, comprise permanent layer and working lining, and it is characterized in that: this permanent layer and working lining are integrated, and constitute permanent working lining.
Adopt said structure, because permanent layer and working lining are integrated, it is more sturdy and durable than hierarchy, and the two structure that unites two into one can be avoided changing the different interlayer cracks that produce because of line between ladle liner permanent layer and the working lining, and can remedy the crackle that is produced because of cast each other, safety in utilization is good; Because this structure is used when reaching certain bag and needing repairing age at ladle, residue, conversion zone and the metamorphic layer and the cover that only need removing bag wall to water in the material feeding water and can use repeatedly, can shorten the ladle maintenance construction cycle, reduce the use cost and the maintenance cost of ladle integral pouring liner.
Be provided with heat-insulation layer in the described permanent working lining outside, heat-insulation layer can reduce molten steel heat conduction to external world, realizes the casting of cold melt and constant temperature.
The thickness of described heat-insulation layer can be 10-20mm, and the thickness of permanent working lining is 230-300mm.
Description of drawings
Fig. 1 is the inner lining structure schematic diagram of the utility model ladle wall.
Among the figure: 1. permanent working lining 2. heat-insulation layers 3. ladle shell walls 4. slag line bricks
The specific embodiment
As shown in Figure 1, ladle wall inner lining structure of the present utility model comprises permanent layer and working lining and heat-insulation layer, and this permanent layer and working lining are integrated, and constitute permanent working lining 1, and described heat-insulation layer 2 is located at permanent working lining 1 outside.The thickness of described heat-insulation layer 2 is 10-20mm, and the thickness of permanent working lining 1 is 230-300mm.Inboard, upper end at permanent working lining 1 is provided with slag line brick 4, then is ladle shell wall 3 in the outside of heat-insulation layer 2.
Claims (3)
1. a ladle wall inner lining structure comprises permanent layer and working lining, and it is characterized in that: this permanent layer and working lining are integrated, and constitute permanent working lining.
2. ladle wall inner lining structure according to claim 1 is characterized in that: be provided with heat-insulation layer in the described permanent working lining outside.
3. ladle wall inner lining structure according to claim 1 is characterized in that: the thickness of described heat-insulation layer is 10-20mm, and the thickness of permanent working lining is 230-300mm.
