Abstract
The utility model discloses a novel steel ladle cover which is characterized in that a barrel-shaped ladle cover outer shell with a lower end opening is included, the upper end of the ladle cover outer shell is provided with six reinforcing ribs which are welded with hanging rings, the inner wall of the upper bottom of the ladle cover outer shell is welded with mushroom nails with upward tip ends, and the remaining space of the ladle cover outer shell is filled with padding formed by windshield washer fluid and light corundum materials in the proportion of 9:1. According to the novel steel ladle cover, the problem of safety due to not solid structure of the ladle cover and the problem that fire-resisting materials can fall easily due to the not tight inner structure of the ladle cover are solved.
Description
Technical field
The utility model relates to a kind of novel ladle clad.
Background technology
A few days ago, the ladle clad that uses that uses is the support box hat of Plate Welding, the inner knotting of clad structure of refractory.Not only exist clad insecure, dangerous, service life is short, change present situation frequently, and refractory material in use comes off because the institutional framework imprecision cracks progressively, cause ladle clad heat-insulating property to descend, the ladle molten steel temperature drop increases, and the generation non-metallic inclusion that reacts to each other between nonmetalloid in the refractory material that comes off simultaneously and molten steel causes secondary pollution to molten steel, and steel product quality is caused adverse effect.
Up to now, the new technology of making ladle clad and the open report of device for carrying out said are not yet arranged.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of novel ladle clad, and its safety problem and clad internal structure imprecision that has solved the insecure generation of clad structure causes refractory material to hold caducous two difficult problems.
For reaching above purpose, the technical scheme that the utility model adopts is:
A kind of novel ladle clad, the tubular clad shell that comprises lower ending opening, the upper end of clad shell is provided with reinforcement and suspension ring, and the upper base inwall of clad shell is fixed with the large a plurality of taperers of change from top to bottom, is filled with charges in clad shell remaining space.
Further, described charges are the mixture of bath of glass and lightweight corundum material.
Further, the mixed proportion of described bath of glass and lightweight corundum material is 9:1.
Further, ladle body bottom is provided with annular and closes up, and is provided with backing ring in closing in, and the upper end of backing ring and clad shell close contact, lower end and closing in close contact, described charges are positioned at the tubular structure that backing ring forms.
Further, the thick 30mm of described backing ring.
Further, described reinforcement radially arranges; Six altogether of reinforcements, evenly arrange, and suspension ring are fixed on reinforcement.
Further, described taperer is the mushroom nail, mushroom nail space, interval 10cm.
Operation principle of the present utility model and have a mind to effect and show:
Characteristics in conjunction with clad distortion in the past, become an overall structure innovative design to become the hexahedron fabricated structure that is welded into by reinforcement by original Plate Welding clad, not only guarantee the combined type clad not because each parts local deformation causes bulk deformation, and facilitated the making maintenance and repair of hexahedron combined type clad.Designed combined type ladle clad frame structure, can support ladle clad lifting safety problem, can guarantee again the distortion that variations in temperature produces, and can reuse.
To sum up:
1) ladle clad optimal design is become combined type reinforcement steel construction, between each reinforcement, angle is 60 °, whole clad is hexahedral circle, utilizes reinforcement to guarantee fastness and the stability of clad, has guaranteed because each parts local deformation causes bulk deformation problem points forelock, not give birth to.
The situation of 2) for original clad refractory material, easily collapsing material, falling to expect, invent out at clad inner body wall welding mushroom nail, the point upward of mushroom nail, form the traction action to filler, the effect of fastening refractory material is arranged, guarantee that refractory material is firmly whole.
3) replace original castable with the compound of lightweight corundum refractory and bath of glass, strengthened stability and the persistence of refractory material knotting.The compound of lightweight corundum refractory and bath of glass is evenly tied a knot at the clad inwall that is welded with the mushroom nail, between clad and anti-material, no longer direct fixed bonding together, but the backing ring that is 30mm by a thickness is fixed together them, balance has been alleviated the internal stress that the temperature difference is brought, and has improved the thermal shock resistance of ladle clad.
3) this invention thoroughly changes that steel-making at present is short with ladle clad service life, heat insulation effect is poor, changes present situation frequently.Reduce simultaneously because clad inside frequently comes off because the topology layout imprecision causes anti-material, reduce anti-material to the molten steel secondary pollution, further improved slab quality.
4) utilize the lightweight corundum refractory to replace original castable, with bath of glass, according to the ratio of 9:1, carry out proportioning, guarantee the firm, stable of compound.
5) the ladle temperature drop decreased drastically than in the past, had improved heat insulation effect, had reduced production cost.
