Abstract
The utility model relates to the field of centrifugal casting, in particular to a device for preventing oxidation and preserving heat of molten steel in a casting ladle. The device comprises the casting ladle and a gas hose, wherein a protective cover is arranged on the outer circle of the casting ladle; heat-preserving cotton is filled into the heat-preserving cover through a fixing device; the upper part of the heat-preserving cover is provided with a stainless steel connecting joint; the stainless steel connecting joint is connected with an inertia gas tank through the gas hose. According to the device, the molten steel can be prevented from being contacted with air during transferring in the casting ladle, oxidation is prevented, the heat loss in a transferring process is reduced, the cooling speed is lowered, and the casting temperature is ensured during casting of the molten steel.
Description
Technical field
The utility model relates to centrifugal casting field, particularly relates in a kind of casting ladle that molten steel is anti-oxidation, attemperator.
Background technology
Molten steel is transported in the process of centrifugal casting machine after tapping, and molten steel contacts oxidizable with air, and cooling velocity is very fast, in order to guarantee the resistance to elevated temperatures of spun cast pipe, thereby in casting ladle, adds ferrotianium, ferrozirconium.Due to the very easily oxidation under high-temperature condition of ferrotianium and ferrozirconium, existing by molten steel surface, spread the agent of one deck protection against oxidation prevent molten steel transport process in the oxidation of molten steel, but this can not fundamentally solve the problem of molten steel oxidation.
Summary of the invention
The utility model object will provide in a kind of casting ladle that molten steel is anti-oxidation, attemperator exactly, and it can overcome the existing above defect of existing apparatus.
The purpose of this utility model is achieved in that in a kind of casting ladle that molten steel is anti-oxidation, attemperator; comprise casting ladle, air hose; it is characterized in that: described casting ladle outer ring is provided with protective cover; described insulation shroud inside is filled with heat-preservation cotton by fixture; insulation shroud top is provided with stainless steel jointing, and described stainless steel jointing is connected with inertia gas tank by air hose.
Insulation shroud described in the utility model mates with casting ladle mouth bore, and covers on casting ladle mouth.
The utility model, by blown inert gas, does not contact anti-oxidation with air when molten steel is transported in casting ladle; Add a cover the insulation shroud that is filled with heat-preservation cotton, reduced the thermal losses in transport process, reduced cooling velocity, thus the pouring temperature while guaranteeing molten steel cast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, casting ladle; 2, fixture; 3, heat-preservation cotton; 4, insulation shroud; 5, stainless steel jointing; 6, air hose; 7, inertia gas tank.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
With reference to accompanying drawing, anti-oxidation, the attemperator of molten steel in a kind of casting ladle, comprise casting ladle 1, air hose 6, it is characterized in that: described casting ladle 1 outer ring is provided with protective cover 4, described insulation shroud 4 inside are filled with heat-preservation cotton 3 by fixture 2, insulation shroud 4 tops are provided with stainless steel jointing 5, and described stainless steel jointing 5 is connected with inertia gas tank 7 by air hose 6; Protect described 1 mouthful of bore of insulation shroud 4 and casting ladle and mate, and cover on casting ladle mouth.During concrete enforcement, input flexible pipe guarantees enough length, avoids hanging in turning occurring pullling, inert gas passes through air hose, enter in the space of casting ladle and insulation shroud and play air-isolation, effectively prevented that air from contacting with molten steel, reaches the object of anti-oxidation; Heat-preservation cotton is installed in insulation shroud, there is the effect of heat-insulation and heat-preservation, in conjunction with the insulation effect of casting ladle itself, can effectively reduce the loss of heat, reach the effect that reduces cooling velocity, thus the temperature of molten steel while guaranteeing cast.
