Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of molten iron inoculation, and particularly relates to a multi-chamber inoculation device. BACKGROUND

[0002] Molten iron inoculation treatment refers to adding a certain amount of inoculant to molten iron under certain conditions before pouring, so as to change the solidification process of the molten iron. Inoculation treatment can effectively promote the morphological transformation of graphite in the molten iron, making it finer, rounder and more evenly distributed, thereby reducing the stress concentration phenomenon in the castings and improving the strength and toughness of the castings. In addition, inoculation treatment can also refine the eutectic groups and graphite particles in the molten iron, which further enhances the mechanical properties and fatigue resistance of the castings.

[0003] With the increasing demand for large castings in the casting industry, a single pouring basin can no longer accommodate the total amount of molten iron required by multiple ladles. Therefore, the draw plug pouring technology has gradually become the mainstream choice. When using this technology, a pouring basin is designed to simultaneously receive molten iron from multiple ladles, while removing the slag on the surface of the molten iron during pouring. With such a pouring method, a pouring basin is needed to receive molten iron from multiple ladles, and at the same time, the problem of choosing a stream inoculation device or stream inoculation method arises.

[0004] Currently, foundries usually put inoculation blocks directly into ladles, melt them using the high temperature of the molten iron, thereby achieving the purpose of inoculating the molten iron, and then pouring the molten iron into the pouring basin.

[0005] However, this inoculation method can cause uneven mixing between the inoculation blocks and the molten iron, leading to uneven inoculation. In addition, the start time of inoculation cannot be accurately controlled, thereby affecting the inoculation effect. SUMMARY

[0009] The multi-chamber inoculation device of the utility model adopts the inoculation hopper of multi-chamber, can improve the uniformity of molten iron inoculation, and can control the time of inoculation start, improve the effect of inoculation, effectively delay the process of inoculation recession.
