Abstract
The utility model provides a novel energy-saving molten steel ladle, which is capable of solving the problem of high maintenance cost of an original energy-saving molten steel ladle. The technical scheme includes that the novel energy-saving molten steel ladle sequentially comprises a working layer, a permanent layer, a lining wall, a heat insulation material and a wrapping wall, wherein the lining wall is arranged between the permanent layer and the heat insulation material. The novel energy-saving molten steel ladle is characterized in that the lining wall is made of steel plates.
Description
Technical field
The utility model relates to the cask technical field that is used for metallurgical industry, is specially a kind of novel energy-saving molten steel jar.
Background technology
Molten steel jar be otherwise known as ladle, steel ladle, ladle etc.; The molten steel jar plays a part to store in metallurgical industry, the transhipment molten steel; The variations in temperature that its heat transfer meeting in producing circular flow directly influences tapping and contains molten steel in the steel process; And the variation of liquid steel temperature also will produce very big influence to external refining and casting cycle, and the quality of final products is impacted, and this possesses good heat protection function with regard to the structure that requires the molten steel jar.And general molten steel jar; See Fig. 1, it comprises wall 4, and bag wall 4 madial walls are laid the permanent layer of being processed by refractory material 2 and working lining 1; It in use wraps, and wall 4 temperature are high, heat loss is big; So the molten steel jar that at present domestic indivedual steel mills use is attempted in permanent layer 2 and wrapped the thermal protection performance that the mode that overlays heat-insulating material between the wall 4 improves the molten steel jar, its structure comprises working lining, permanent layer, heat-insulating material and Bao Bi, and heat-insulating material wherein generally adopts the nanometer micropore heat-insulating shield; Because the nanometer micropore heat-insulating shield is a kind of soft material that does not have rigidity, no intensity; Therefore before the laying of carrying out permanent layer 2 and working lining 1, need carry out the reinforcement on surface to it, known mode is to lay one deck ceramic fibre, adhesion between ceramic fibre and the nano-plates in the spraying of nanometer micropore plate surface at present; Its shortcoming is: because the restriction in service life of working lining and permanent layer needs periodic replacement; When changing working lining and permanent layer, be prone to ceramic fibre and nanometer micropore heat-insulating shield are destroyed in the lump, and costing an arm and a leg of nanometer micropore heat-insulating shield is therefore very high by the molten steel jar maintenance cost after this architecture advances; In addition; Because it has clamped ceramic fibre and heat-insulating material between permanent layer and bag wall; Make molten steel jar aqueous vapor in its working lining and the permanent layer in holding the course of work of molten steel to discharge smoothly through the air-vent 8 on the bag wall 4; A large amount of aqueous vapors cause shorten the service life of working lining and permanent layer in working lining and the expansion of permanent layer accumulated, final failure working lining and permanent layer, have increased the maintenance cost of molten steel jar.
Summary of the invention
To the very high defective of existing molten steel jar maintenance cost, the utility model provides a kind of novel energy-saving molten steel jar, and it can solve the high problem of original energy-saving molten steel jar maintenance cost.
Its technical scheme is such: it comprises working lining, permanent layer, lining, heat-insulating material and Bao Bi successively, and said lining is arranged between said permanent layer and the said heat-insulating material, it is characterized in that: said lining is a steel plate.
It is further characterized in that: described heat-insulating material is the nanometer micropore heat-insulating shield; Fixing through the pull bar connection between said lining, heat-insulating material and the bag wall, said pull rod shaft is to having through hole; Said pull bar two ends are fixed with said lining, the welding of bag wall respectively.
The utility model adopts after the said structure; Its beneficial effect is: it has substituted the ceramic fibre in the original structure by steel plate; Steel plate can play a protective role to the heat-insulating material surface, avoid the damage to insulating panels when changing working lining and permanent layer, thereby has reduced the maintenance cost of molten steel jar; And; Connect fixing through the pull bar that has axially extending bore between its lining, heat-insulating material and the bag wall; Through hole on the pull bar can effectively play the effect of air-vent; Guaranteed the molten steel jar in use the aqueous vapor in working lining and the permanent layer discharge smoothly, thereby prolong the service life of working lining and permanent layer, further reduced the maintenance cost of molten steel jar.
Description of drawings
Fig. 1 is general molten steel jar structure sketch map;
Fig. 2 is the energy-saving molten steel jar structure sketch map of the utility model.
The specific embodiment
See Fig. 2; The utility model comprises working lining 1, permanent layer 2, lining 5, heat-insulating material 3 and bag wall 4 successively, and heat-insulating material 3 is the nanometer micropore heat-insulating shield, and lining 5 is between permanent layer 2 and heat-insulating material 3; Heat-insulating material 3 in the present embodiment is the nanometer micropore heat-insulating shield, and lining 5 adopts sheet metal.In the present embodiment, reliable for clamping of nanometer micropore heat-insulating shield, can carry out clamping through the mode that pull bar 6 is welded to connect between lining 5, nanometer micropore heat-insulating shield, the bag wall 4, pull bar 6 two ends are fixing with 4 welding of bag wall with lining 5 respectively; Pull bar 6 axially has through hole 7; Through hole 7 can play the effect of air-vent; Since working lining and permanent layer be by refractory material process, it all keeps certain moisture content; Working lining and permanent layer can be discharged the molten steel jars through through hole 7 after meeting the water evaporates in hot intensification, its material smoothly when the molten steel jar holds molten steel, guarantee the service life of working lining 1 and permanent layer 2, the maintenance cost of reduction molten steel jar.
