Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, specifically to an adjustable in-flow inoculation device for valve body casting. Background Technology

[0002] Inoculant flow metering devices are key equipment in the casting process, primarily used to precisely control and quantitatively add inoculants (such as ferrosilicon and zirconium alloys) during molten metal pouring to improve the microstructure, mechanical properties, and defect control of castings. Their core function is to ensure the casting achieves ideal solidification results by dynamically adjusting the amount, flow rate, and mixing uniformity of the inoculant.

[0003] Chinese Patent Publication No. CN205289679U discloses a flow-fed inoculation device for casting. The device includes a material cylinder, a support, a control device, and a flow guide. The material cylinder is located at the top of the support, which consists of at least three legs. A fixing rod is provided laterally in the middle of the legs. The flow guide is located above the fixing rod and directly below the outlet of the material cylinder. The control device is located below the outlet of the material cylinder. The upper end of the material cylinder is cylindrical, and the lower end is conical.

[0004] The casting in-flow inoculation device involved in the above patent still has some obvious shortcomings in actual use. The device lacks a structure for adjusting the angle of the unloading cylinder, which makes it difficult to control the flow rate of in-flow inoculation and affects the amount of inoculant used. Therefore, we need to propose an adjustable in-flow inoculation flow rate device for valve body casting. Utility Model Content
