Abstract
The utility model relates to a safe steel ladle liner which is characterized in that the liner comprises a steel ladle body, a heat preservation layer, a permanent liner body, a safe liner body and a work liner body, the steel ladle body is sequentially provided with the heat preservation layer, the permanent liner body, the safe liner body and the work liner body from outside to inside, the safe liner body is formed by magnesia carbon brick layers or aluminum magnesia carbon brick layers with laying seams distributed in a staggered mode in the vertical direction, the thickness of the safe liner body is 20-100 mm, the work liner body is formed by laying magnesia carbon bricks or aluminum magnesia carbon bricks, and the thickness of the work liner body is 100-200 mm. Compared with the prior art, the safe steel ladle liner has the advantages that steel ladle laying construction period is shortened, expert professional ladle judging staff are not needed for ladle judging, any one person can judge ladles, safety of steel ladles is improved, the steel ladle leakage accident is avoided, steel ladle refractory matter consumption is lowered, the safe liner body can be used permanently, the using number of the magnesia carbon bricks or the aluminum magnesia carbon bricks of the work liner body is reduced, and the service life of steel ladles is prolonged.
Description
Technical field
The utility model relates to ladle technical field, particularly a kind of safe ladle liner.
Background technology
Ladle is one of STEELMAKING PRODUCTION visual plant, and the condition of work of ladle is very harsh, and severe impact when liner bears the static pressure of high-temperature molten steel and taps, stands the chilling and shock heating effect of mechanical erosion, chemical erosion and temperature sharply.Make molten steel ladle inner lining produce melting loss, when serious, cause ladle leakage accident, bring hidden danger to safety in production.
Conventional ladle is inwardly disposed with heat insulation layer, permanent liner and working lining from shell, because permanent layer pouring materialfor steel ladle can not be resisted molten steel erosion well, in the time that having corroded, slag line working lining refractory brick very easily cause slag line to wear bag, therefore, for preventing that ladle leakage accident from occurring, usually, in the time that working lining also has certain thickness, remove working lining, cause great waste.
Summary of the invention
The purpose of this utility model is to provide a kind of waste that reduces working lining magnesia carbon brick or aluminium-magnesia carbon brick, the safe ladle liner saving production cost.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of safe ladle liner, is characterized in that, comprise ladle main body, heat-insulation layer, permanent liner, safety liner and working lining, described ladle main body ecto-entad is provided with heat-insulation layer, permanent liner, safety liner and working lining successively.
Described safety liner is dislocatedly distributed and forms at the puzzle joint of vertical direction by magnesia carbon brick layer or aluminium-magnesia carbon brick layer, and the thickness of safety liner is between 20-100mm.
Described working lining is built by laying bricks or stones and is formed by magnesia carbon brick or aluminium-magnesia carbon brick, and the thickness of working lining is between 100-200mm.
Described magnesia carbon brick or aluminium-magnesia carbon brick are fan-shaped or wedge structure.
Compared with prior art, the beneficial effects of the utility model are:
1, build working lining by laying bricks or stones, in the time that ladle working lining corrodes damage to safety liner, can build in time working lining by laying bricks or stones, in resisting the erosion of molten steel, stopping the generation of ladle leakage accident, shortened the duration of ladle building construction.
2, due to the introducing of safety liner, make the job contract of sentencing of ladle become light, sentence bag personnel without the need for the specialty of experience and sentence bag, use while exposing safety liner at steel ladle working lining brick, can build the working lining of next bag labour by laying bricks or stones, anyone can sentence bag.
3, with the permanent liner ladle comparison that adopts pouring materialfor steel ladle cast, due to many one deck safety liner protections, the security that has greatly improved ladle.
4, the erosion that still can resist molten steel in use procedure after ladle working lining erosion is damaged, the generation of having stopped ladle leakage accident, can build working lining by laying bricks or stones again, has reduced the consumption of ladle lining compared with original method, has saved cost.
5, be increased to the service life of ladle permanent lining unlimited more than, safety liner also can use for a long time.
6, owing to increasing safety liner, reduced the usage quantity of working lining magnesia carbon brick or aluminium-magnesia carbon brick, the service life of having improved ladle.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
1-ladle main body, 2-heat-insulation layer, 3-permanent liner, 4-safety liner, 5-working lining
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further illustrated:
As shown in Figure 1, a kind of safe ladle liner of the utility model, it is characterized in that, comprise ladle main body 1, heat-insulation layer 2, permanent liner 3, safety liner 4 and working lining 5, described ladle main body 1 ecto-entad is provided with heat-insulation layer 2, permanent liner 3, safety liner 4 and working lining 5 successively; Described safety liner 4 is dislocatedly distributed and forms at the puzzle joint of vertical direction by magnesia carbon brick layer or aluminium-magnesia carbon brick layer, and the thickness of safety liner 4 is between 20-100mm; Described working lining 5 is built by laying bricks or stones and is formed by magnesia carbon brick or aluminium-magnesia carbon brick, and the thickness of working lining 5 is between 100-200mm; Described magnesia carbon brick or aluminium-magnesia carbon brick are fan-shaped or wedge structure.
Building method of the present utility model, while building by laying bricks or stones, at the bottom of first using pouring materialfor steel ladle pouring construction bag, permanent liner 3 is to specific thickness, then with bag heelpiece material levelling in permanent liner 3 at the bottom of the bag tying of 0-1mm, in permanent liner 3 at the bottom of the bag of levelling, be close to permanent liner 3 ring by ring that wrap wall and build safety liner 4 from bottom to top by laying bricks or stones, in the time just building ladle working lining 5, being close to permanent liner 3 uses magnesia carbon brick or aluminium-magnesia carbon brick between 100-300mm to build by laying bricks or stones, ladle is used and is used after stipulated number at first bag, as required by residual working lining 5 thickness to 20-100mm, the safety liner 4 that residual working lining 5 bricks are used as a servant as next one bag with chamotte levelling, second later working lining of bag labour adopts the magnesia carbon brick of 100-200mm or aluminium-magnesia carbon brick to build by laying bricks or stones, residual safety liner 4 Bao Yizhong afterwards does not remove.
Above, be only basic principle of the present utility model, not the utility model imposed any restrictions, everyly according to the utility model, it is carried out to equivalent variations and modification, all within the category of the art of this patent protection scheme.
