Description

Casting ladle for automatically adding stream inoculant

Technical Field

The utility model relates to the technical field of automatic inoculant addition in the casting process, in particular to a cast ladle for automatically adding stream inoculant.

Background

Inoculant and inoculation process are needed in the production process of the iron casting to improve the existence form, distribution, size, shape and the like of carbon in the iron casting, so that the performance of the iron casting is changed or improved. These properties include, but are not limited to, mechanical properties, cutting properties, natural frequencies, aging properties, and the like. Inoculant is added in the casting production and molding process, and the addition amount of inoculant is usually 0.05% -1% of the total mass of molten iron. The addition amount is not large, but the function is very critical.

In the inoculation process of the iron castings, stream inoculation before molten iron enters a sand mold is the most critical; the automatic flow following equipment used in the casting factory is operated in linkage with an automatic pouring machine at present, is mainly used in automatic line production, and cannot be used for larger castings (such as sand boxes) or factories without automatic lines. Moreover, the automatic casting machine and the automatic flow following device are usually electric, have complex equipment and higher cost, and are not easy to maintain after an accident. It is common for large foundries, or foundries without automation, to operate manually using a flow hopper. Before a ladle is added to a flask, the factory is specially equipped with a person to handle the addition. The defects of the method are as follows: firstly, a labor is additionally added; and two,: the working intensity of workers is high, and in the hot-metal heat radiation environment, the whole casting process needs to hold the long-handle funnel all the time and accurately and quantitatively feed materials; thirdly, the stability is poor. Because of manual operation and long-time labor, fluctuation in adding the stream inoculant is unavoidable, and thus the risk of casting quality is brought.

The present application therefore proposes a foundry ladle for automatically adding a stream inoculant to solve the above-mentioned problems.
