Abstract

The utility model discloses a hot metal ladle heat-preserving device which is a heat-preserving cover used for covering a hot metal ladle. The hot metal ladle heat-preserving device comprises a cap body and a cover body, wherein the shape of the cap body is identical with the shape of a ladle opening of the hot metal ladle, and the cover body is arranged along the edges of the cap body. Heat-preserving cotton is paved on the surface, located in the cover body, of the cap body, and a lifting lug used for lifting is further arranged on the cap body. Compared with the prior art, the hot metal ladle heat-preserving device is provided with the heat-preserving cover capable of covering the hot metal ladle, and the heat-preserving cotton with the very good heat preservation function is further arranged in the heat-preserving cover, thus, heat in the hot metal ladle does not dissipate out easily, and the good heat preservation function is achieved; after the hot metal ladle undergoes pouring, the temperature of the hot metal ladle can be prevented from decreasing, and when the hot metal ladle is used again, heat can be utilized well; outlet cold ladle melted iron is reduced, the decreasing speed of the temperature of the melted iron is reduced, and pouring temperature is ensured.

Description

A kind of ladle insulation device

Technical field

The utility model relates to casting field, and specifically, the utility model relates to a kind of ladle insulation device.

Background technology

In the casting smelting process, first molten iron is poured in the ladle, by ladle molten iron is poured in the casting mold again, the ladle of drying holds molten iron if use not, because both temperature difference are larger, the molten iron cooling will be very fast, the pouring temperature of molten iron is difficult to control like this, so generally before use first with the ladle baking, hold again molten iron, reduce the drop in temperature of molten iron.

Ladle is after being poured, and internal temperature is about 1000 ℃, if ladle can not effectively be incubated, temperature can descend very soon, a large amount of heat loss and well not utilized.

The utility model content

Technical problem to be solved in the utility model provides a kind of ladle insulation device, to prevent that the ladle internal temperature descends after molten iron is poured.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of ladle insulation device, it is a stay-warm case that is used for covering ladle, it comprises the lid identical with the shape of the bag mouth of ladle and the cover body that arranges along the edge of lid, the surface that is positioned at cover body inside at lid is equipped with heat-preservation cotton, also is provided with the hanger for lifting on lid.

Be provided with for the carriage of fixing described heat-preservation cotton in described cover body inside.

Described carriage is made of the channel-section steel of many interlaced connections.

The utility model adopts technique scheme, compared with prior art, by a stay-warm case that can cover on the ladle is set, and stay-warm case inside also is provided with the heat-preservation cotton with good insulation effect, can make like this heat in the ladle be not easy to scatter and disappear away, thereby reach good insulation effect, ladle is after cast, can prevent the ladle drop in temperature, when reusing, heat is well utilized, and has reduced the cold molten iron that contracts out, the decrease speed of molten iron temperature has guaranteed pouring temperature.

Description of drawings

Fig. 1 is the top view of attemperator of the present utility model;

Fig. 2 is the structural representation of lid;

Fig. 3 is the side view of Fig. 2;

Mark among the above-mentioned figure is: 1, lid; 2, cover body; 3, heat-preservation cotton; 4, carriage; 5, hanger.

The specific embodiment

Be illustrated in figure 1 as a kind of ladle insulation device of the present utility model, it is a stay-warm case that is used for covering ladle, this stay-warm case comprises the lid 1 identical with the shape of the bag mouth of ladle and along the cover body 2 of the edge welding of lid 1, the Bao Kouchu that lid 1 covers in ladle, cover body 2 covers ladle downwards, the surface that is positioned at cover body 2 inside at lid 1 is equipped with heat-preservation cotton 3, as shown in Figures 2 and 3, also is provided with the hanger 5 for lifting on the top of lid 1.

Lid 1 is to adopt the thick steel plate of 5mm to form according to the shape cutting of ladle bag mouth, and cover body 2 adopts 5mm steel plate thick, high 140mm to make.

As shown in Figure 1, be useful on the fixedly carriage 4 of heat-preservation cotton 3 in cover body 2 interior welds, prevent that heat-preservation cotton 3 from dropping, this carriage 4 is that the channel-section steel by many interlaced connections consists of, and channel-section steel is of a size of 50 * 50.

The using method of this stay-warm case: after ladle is poured, ladle is placed steadily, re-using drives a vehicle hangs the ladle top with stay-warm case, aims at bag mouthful placement; When the next molten iron discharging, re-using driving stay-warm case is hung away.The method is easy and simple to handle, and the heat-preservation cotton 3 of the inside has good insulation effect, can make the interior heat of bag be not easy to scatter and disappear away, thereby reach good insulation effect.Ladle cast after heat measures good utilization, has reduced the cold molten iron that contracts out, and the decrease speed of molten iron temperature has guaranteed pouring temperature.

The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.

Claims (3)
