Abstract
The invention discloses a ladle lining casting technology, which comprises the following steps: 1) detaching ladle slag brick, cleaning slag on the ladle wall working layer, reacting layer and deteriorated layer, 2) placing the mould to locate, 3) casting between mould and ladle wall with the same material as working layer, 4) stripping after health preserving, 5) toasting.
Description
Technical field
The present invention relates to a kind of ladle neck bush pouring technique.
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.
Summary of the invention
The objective of the invention is at the problems referred to above, a kind of ladle neck bush pouring technique is provided, it 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 present invention's proposition is:
A kind of ladle neck bush pouring technique is characterized in that comprising following processing step:
1) removes ladle wall slag line brick, remove residue, conversion zone and metamorphic layer on the ladle wall working lining;
2) put into loose tool and location;
3) between loose tool and ladle wall cast and the same material of working lining water material feeding;
4) demoulding after the health;
5) baking.
In step 1), the thickness of the working lining of reservation is the 1/3-1/2 of original thickness.
In step 2) described in loose tool location adopt the mode that locating piece is set at the ladle bottom periphery, locating piece is at least three, becomes symmetric arrays, the inboard of locating piece is provided with chamfering, and the material of locating piece is with to water the material feeding material identical.
Watering material feeding described in the step 3) is that aluminum-spinel waters material feeding.
Also comprise a maintenance step in step 4), health and curing time are 24 hours.
Adopt little fire baking 24-48 hour earlier in baking described in the step 5), then with moderate heat baking 16-36 hour, again by big fire baking 8-24 hour.
Ladle neck bush pouring technique of the present invention has the following advantages:
1. can overlap when using stipulated number owing to working lining and water, promptly removing bag wall waters residue, conversion zone and the metamorphic layer in the material feeding, remainder waters material feeding and can be considered the permanent layer reservation, can save the consumption of refractory material like this, implement can to make part bag wall water material feeding after cover waters and recycle, reserve part can use synchronously with permanent layer.Adopt this structure can improve ladle bag age, reduce the ladle liner cost.
2. because to water material feeding identical with former operational layer material, its line changes identical, can form an integral body with former working lining, and steadiness is better, and waters material feeding and can remedy crack on the former working lining, raising ladle safety in utilization.
3. adopt the mode that locating piece is set at ladle bottom to position, locate mode is easy, be convenient to pour into a mould the back and take out loose tool, and the material of locating piece is with to water the material feeding material identical, and locating piece becomes the part of working lining and needn't take out again after cast, and is simple to operate.
4. health, maintenance and baking process are reasonable, can effectively reduce the generation in crack, improve the safety in utilization of ladle.
The specific embodiment
Ladle wall of the present invention adopts integrated poured liner, and it is made up of heat-insulation layer, integrated poured permanent layer and integrated poured working lining etc.Heat-insulation layer can adopt insulations such as flame-retardant fibre board, asbestos board and thermal insulation coatings.At first, warming plate can be fixed on the ladle involucrum by bonding or anchoring piece.Secondly, in the inboard integrated poured permanent layer of heat-insulation layer, then after integrated poured permanent layer health, the demoulding and baking, integrated poured again working lining, water material feeding and can remedy the crack that permanent layer produces simultaneously in bake process, increase ladle security in use.
Permanent layer and working lining use respectively and water material feeding with a kind of ladle working layer and carry out integrated poured.Therefore, the two can finally reach the effect that integrates.
Can overlap when working lining uses stipulated number and water, ladle neck bush pouring technique of the present invention comprises following processing step:
1) removes ladle wall slag line brick, remove residue, conversion zone and metamorphic layer on the ladle wall working lining; The thickness of the working lining that keeps is the 1/3-1/2 of original thickness.
2) place three locating pieces identical with watering the material feeding material at the ladle bottom periphery, three locating pieces become symmetric arrays, are provided with chamfering in the inboard of locating piece, put into loose tool;
3) the same aluminum-spinel of cast and working lining waters material feeding between loose tool and ladle wall;
4) health was taken out loose tool after 24 hours, and maintenance is 24 hours again;
5) adopt little fire baking 30 hours earlier, then with moderate heat baking 20 hours, again by big fire baking 10 hours.
Claims (6)
1. ladle neck bush pouring technique is characterized in that comprising following processing step:
1) removes ladle wall slag line brick, remove residue, conversion zone and metamorphic layer on the ladle wall working lining;
2) put into loose tool and location;
3) between loose tool and ladle wall cast and the same material of working lining water material feeding;
4) demoulding after the health;
5) baking.
2. ladle neck bush pouring technique according to claim 1 is characterized in that: in step 1), the thickness of the working lining of reservation is the 1/3-1/2 of original thickness.
