Abstract
The utility model discloses a ladle with a metal shell. The ladle with the metal shell is used to reduce the heat loss of the molten steel. The structure of the ladle comprises a trunnion, a ladle wall, a bottom-blowing gas inlet and the metal shell, wherein the metal shell is wrapped on the ladle wall, and the bottom-blowing gas inlet is arranged in the middle of the ladle. The ladle with the metal shell utilizes the heat emitted by the ladle to heat bottom-blowing gas. After the temperature of the bottom-blowing gas rises, the ladle is arranged to shorten the temperature difference of the bottom-blowing gas and the ladle and to reduce temperature drop of the ladle. Meanwhile, a thermal insulating layer is formed by gas between the ladle wall and the metal shell to effectively reduce heat loss. The ladle with the metal shell is long in service life, stable in performance, and capable of being applied in improvement of prior equipment by low cost.
Description
Technical field
The utility model belongs to metallurgical equipment.Particularly relate to a kind of ladle with metal shell.
Background technology
Ladle is not only the container of transportation molten steel, also is the part of double refining.Molten steel can be blown into nitrogen after converter is contained ladle during entering refining process or argon gas stirs, and gas enters in the ladle and heated by high-temperature molten steel, and molten steel temperature reduces, and causes a large amount of heat loss.
Mainly by refractory brick, Bao Bi, gudgeon partly forms existing ladle.In use, the ladle wall heat radiation accounts for 15-25% of molten steel heat loss, reduces the temperature drop that this part heat loss can effectively reduce molten steel, saves production cost.And be uneconomic with the method that increases refractory material and improve tapping temperature.
The utility model content
The utility model provides a kind of ladle with metal shell, reduces the molten steel heat loss.
A kind of ladle with metal shell that the utility model provides, its structure comprises: gudgeon, steel ladle, characterized by further comprising bottom blown gas entrance and metal shell, metal shell is wrapped on the steel ladle, and the bottom blown gas entrance is located at the ladle middle part.
Bottom blown gas is introduced into the space between steel ladle and the metal shell, utilizes the heat heating bottom blown gas of ladle radiation, and the gas after the heating passes into and stirs molten steel in the ladle.
The utility model is compared with existing same category of device, and its beneficial effect is embodied in:
The heat heating bottom blown gas that utilizes ladle to give out passes into the temperature difference that ladle can dwindle bottom blown gas and molten steel after the rising bottom blown gas temperature again, reduces molten steel temperature drop, and the gas between the Bao Biyu metal shell forms thermal insulation layer and effectively reduces heat loss simultaneously.With ladle long service life, the stable performance of metal shell, can low cost be applied to the existing equipment transformation.
Description of drawings
Fig. 1 is a kind of ladle structural representation with metal shell.
Number among the figure: 1 is gudgeon, and 2 is the bottom blown gas entrance, and 3 is metal shell, and 4 is steel ladle.
The specific embodiment
As shown in Figure 1, by gudgeon 1, steel ladle 4, bottom blown gas entrance 2 and metal shell 3 consist of with the ladle of metal shell, and metal shell 3 is wrapped on the steel ladle by welding, and the bottom blown gas entrance is located at the ladle middle part.
Claims (1)
