Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0021] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.
[0022] Such as Figure 1-2 Shown is an implementation form according to the invention, which includes:
[0023] The inoculant container 4 is provided with an accommodating cavity in which the inoculant is pre-placed in the accommodating cavity, and a supplementary inoculant can be added to it at any time according to the inoculation delivery situation. The lower part of the inoculant container 4 The end face is provided with a discharge hole 6, and the inoculant flows out from the discharge hole; the upper end of the discharge launder 7 is rotatably arranged at the lower end of ...

The invention discloses a stream quantitative feeding device for a nucleating agent. The stream quantitative feeding device for the nucleating agent comprises a nucleating agent container, a discharging runner and a baffle, wherein a containing cavity is formed in the nucleating agent container, the nucleating agent is contained in the containing cavity, and a discharging hole is formed in the lower end face of the nucleating agent container; the upper end of the discharging runner is arranged at the lower end of the discharging hole in a rotating mode, and the lower end of the discharging runner extends downwards in a tilting mode; one end of the baffle is movably arranged at the discharging hole, and a connection rod extends downwards from the other end of the baffle and is connected with the discharging runner; and a spring used for providing reset force for the baffle is arranged between the upper surface of the baffle and the lower end face of the nucleating agent container. By means of the stream quantitative feeding device for the nucleating agent, the technical problems that a nucleating agent is poor in nucleating effect and prone to fading and is used too much are effectively solved, and the quality of castings is effectively improved.
Description
technical field [0001] The invention relates to the technical field of metallurgy, in particular to a flow-by-flow quantitative dosing device for an inoculant. Background technique [0002] In the casting process, inoculants are used more and more frequently. Inoculants are additives added to the alloy liquid to promote the preferential nucleation of a certain phase, which can effectively improve the mechanical properties of castings and reduce internal stress and wall thickness. Sensitivity, mainly suitable for various castings or post-instantaneous inoculation. Adding inoculants is a very important process in the pouring process. The general treatment method is: first put inoculants into the ladle, and then pour molten iron into the ladle. [0003] However, the disadvantage of this addition method is that the inoculant is put into the ladle prematurely, which makes the inoculation effect worse, easily causes inoculation decline, increases the amount of inoculant used, and...
