Description

Technical Field

[0001] The invention relates to the technical field of presses, in particular to an automatic leveling and compacting mechanism for ladle bottom material. Background Art

[0002] During the process of iron casting, it is necessary to spheroidize and inoculate the molten iron while pouring it into the ladle. This tempering process is called flushing spheroidization and inoculation. It is necessary to add the inoculant, spheroidizing agent, and covering agent (hereinafter referred to as the three materials) to the groove position specified at the bottom of the ladle in advance. Generally, the inoculant, spheroidizing agent, and covering agent are added in sequence, and then the molten iron is poured in. Inoculation and spheroidization are carried out during the flushing process to improve the quality of the molten iron.

[0003] The process requires that during the injection process, the spheroidizing agent, inoculant, and covering agent are gradually released and fully mixed with the molten iron to react in order to obtain molten iron that meets the requirements. In other words, the ideal situation is that the inoculant, spheroidizing agent, and covering agent should participate in the reaction in sequence as the entire package of molten iron is injected. In reality, due to the large impact force, the three materials are often dispersed and reacted too early, which will not achieve the ideal effect.
