Abstract
The utility model discloses a novel molten steel pouring funnel which comprises a funnel brick and an iron skin cap, wherein the iron skin cap is conical, the diameter of the bottom of the iron skin cap is larger than that of the opening of the funnel, the iron skin cap is arranged on the funnel brick, the thickness of an iron skin of the iron skin cap is 0.5-1mm, a leakage hole is formed at the bottom of the funnel brick, and the leakage hole is connected with a straight runner. When the novel molten steel pouring funnel is used, a steel ladle eye is opened, drainage sand flows out firstly and then flows to the outside of the funnel brick along the iron skin cap, then molten steel flows out, as the temperature of the molten steel is higher and the iron skin of the iron skin cap is thinner, the iron skin cap is melt by the molten steel, and the molten steel enters the funnel brick and then a cavity through the pouring runner, the drainage sand can also be guided by the iron skin cap to the outside of the funnel, sand holes are prevented from forming on the product, the product quality is guaranteed, in addition, the device has a simple structure, is convenient to use and improves the product quality.
Description
Technical field
The utility model relates to a kind of cast instrument, relates in particular to a kind of novel liquid steel depositing funnel.
Background technology
Cast steel pouring cast part and steel ingot need the funnel brick, and molten steel flows into sprue through the funnel brick, and existing placing adopts the cast of slide gate nozzle bottom pour ladle; Drainage sand need be put in the ladle molten steel exit; Open the bag eye during cast, drainage sand is emitted earlier and is afterwards got into the funnel brick, gets into the funnel brick after steel flow is come out subsequently; The drainage sand flow can form sand holes in foundry goods or steel ingot like this, has had a strong impact on product quality.
The utility model content
The purpose of the utility model is exactly in order to address the above problem, and a kind of novel liquid steel depositing funnel is provided, and it has simple in structure, and is easy to use, advantages such as product quality raising.
To achieve these goals, the utility model adopts following technical scheme:
A kind of novel liquid steel depositing funnel comprises funnel brick and iron sheet cap, and the iron sheet cap is conical, and iron sheet cap base diameter is greater than the bell mouth diameter, and the iron sheet cap is installed on the funnel brick.
Iron sheet cap thickness of scale is 0.5-1mm.
Funnel brick bottom is provided with small opening, and small opening connects sprue.
Open ladle bag eye during use, drainage sand can flow out earlier, and it is outside that drainage sand can be left to the funnel brick along the iron sheet cap; Molten steel flows out subsequently, because liquid steel temperature is higher, iron sheet cap thickness of scale is thinner; Molten steel melts the iron sheet cap, and gets into the funnel brick, gets into die cavity through running channel.
The beneficial effect of the utility model:
The utility model can be outside at funnel with the guiding of drainage sand through the iron sheet cap, avoided forming sand holes on the product, guaranteed product quality, and apparatus structure is simple, and is easy to use, improved product quality.
Description of drawings
Fig. 1 is a pouring molten steel infundibular ganglion composition.
Wherein, 1. iron sheet cap, 2. funnel brick, 3. running channel.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, when using, opens the utility model ladle bag eye, and drainage sand can flow out earlier; Drainage sand can be left to funnel brick 2 outsides along iron sheet cap 1, and molten steel flows out subsequently, because liquid steel temperature is higher; Iron sheet cap 1 thickness of scale is thinner; Molten steel melts iron sheet cap 1, and gets into funnel brick 2, gets into die cavity through running channel 3.
Though the above-mentioned accompanying drawing that combines is described the specific embodiment of the utility model; But be not restriction to the utility model protection domain; One of ordinary skill in the art should be understood that; On the basis of the technical scheme of the utility model, those skilled in the art need not pay various modifications that creative work can make or distortion still in the protection domain of the utility model.
