Abstract

The utility model relates to a steel-clad or ladle liners. Technical proposal: the steel-clad or ladle liners are composed of a working layer [1] and a permanent layer [2]; the permanent layer [2] of the steel-clad or ladle liners closely touches the shell [3] of steel-clad or ladle, and the permanent layer [2] of the steel-clad or ladle liners is made of light insulating fire bricks; the working layer [1] of the steel-clad or ladle liners closely steel-clad or ladle liners the permanent layer [2], wherein the working layer [1] of the steel-clad is cast out of magnesia light castable refractory or made of Aluminum-magnesia-carbon bricks, while the working layer [1] of ladle is cast out of A12O3-SiC castable refractory or made of A12O3-SiC fire bricks. The utility model is characterized by: high strength, excellent resistance to heat shocks, low volume concentration, simple processes and low cost etc.

Description

A kind of ladle and ladle liner
One, technical field
The utility model belongs to the outer auxiliary equipment of metallurgical furnace.Relate in particular to a kind of ladle or ladle liner.
Two, background technology
Ladle is as steelmaking equipment, and along with the continuous progress of steel-smelting technology, effect and function that it is brought into play in steelmaking system are more and more important.Improving constantly of furnace outer refining technology particularly, the holdup time of molten steel in ladle is long, and the refractory material heat insulation effect of ladle liner permanent layer is had higher requirement.
Ladle is as the important Thermal Equipment of delivery molten iron, and molten iron time of staying in ladle is long, and its heat insulation effect is directly connected to the temperature drop of molten iron, the production of influence steel-making, and serious meeting causes freezes the bag phenomenon.
The liner permanent layer of existing ladle or ladle has waters material feeding with clay brick, high-alumina brick, half lightening casting material and heavy and builds by laying bricks or stones or pour into a mould, but clay brick, high-alumina brick, heavy water material feeding bulk density height, thermal conductivity height; And half lightening casting material intensity is low, thermal shock resistance is poor, the construction technology complexity; In addition, the heat preservation and insulation of above-mentioned material is relatively poor, will cause the temperature drop of molten steel or molten iron bigger, can not satisfy the temperature drop requirement of molten steel or molten iron.
The liner permanent layer of existing ladle or the ladle also thermal insulation of useful good heat-insulation effect watt is built by laying bricks or stones, but since adiabatic watt exist shortcomings such as weak point in service life, poor stability, difficulty of construction are big, restricted using and promoting of it.
Three, summary of the invention
The purpose of this utility model provides a kind of intensity height, good thermal shock, bulk density is low, thermal conductivity is low, construction technology is simple, cost is low ladle and ladle liner.
For finishing above-mentioned task, the technical scheme that the utility model adopted is: ladle or ladle liner are made up of working lining and permanent layer; The permanent layer of ladle or ladle liner is close to the shell of ladle or ladle, and the permanent layer of ladle or ladle liner is built by laying bricks or stones with light heat-insulating fire resistant brick; The working lining of ladle or ladle liner is close to permanent layer, and the working lining of ladle is built the working lining Al of ladle by laying bricks or stones with the magnesia fireproof casting material cast or with aluminium-magnesia carbon brick 2O 3Al is poured into a mould or used to-SiC refractory casting material 2O 3-SiC refractory brick is built by laying bricks or stones.
Because adopt technique scheme, the utility model is compared with existing ladle or ladle liner, has following significant advantage:
1, the permanent layer of ladle and ladle liner adopts light heat-insulating fire resistant brick, with existing insulating fire brick very big difference is arranged.Because its production technology uniqueness, under the prerequisite that guarantees lower thermal conductivity factor, intensity, thermal shock resistance are significantly higher than existing insulating fire brick.
2, light heat-insulating fire resistant brick is applied to ladle or ladle permanent layer, uses the clay that is complementary with it to build by laying bricks or stones, and lining body overall performance is good, need not toast, and difficult drop-off when turning over bag, for ease of maintenaince.And water material feeding as permanent ladle layer, not only need long-time baking after the construction, and during the demoulding, bag collapses easily.
3, the thermal conductivity factor of light heat-insulating fire resistant brick waters material feeding less than clay brick, high-alumina brick, half lightening casting material and heavy, and good heat insulation and preservation effect is arranged, and can effectively stop the temperature drop of molten steel or molten iron.Molten steel temperature drop diminishes, and can reduce the converter tapping temperature on the one hand, can reduce the dross of ladle on the other hand.
4, the thermal shock resistance of light heat-insulating fire resistant brick is good, can satisfy the frequent instructions for use of big, the cold and hot variation of the temperature difference in the periodic job process of ladle or ladle, and adiabatic watt under this service condition, and easily efflorescence causes working lining loosening.
5, the bulk density of light heat-insulating fire resistant brick is less, can effectively alleviate the weight of ladle or ladle.Under the equal volume situation, water material feeding with high-alumina brick and heavy and compare, weight can reduce by 50%, compares with clay brick, and weight can reduce by 40%.Because of its bulk density is little, make the weight of building ladle or foundry ladle brick by laying bricks or stones reduce on the one hand, make cost descend; Ladle or ladle weight saving on the other hand can reduce the load of driving, improves the usage safety performance of driving.
Four, description of drawings
