Description

Technical Field

[0001] This utility model relates to the field of high-temperature alloy master alloy casting technology, specifically a pouring nozzle for casting high-temperature alloy master alloys. Background Technology

[0002] A gating nozzle is a specialized device used to guide molten steel from the tundish into the ingot mold. Its core design utilizes a raised inner wall structure to precisely control the flow rate and stability of the molten steel, thereby improving casting quality. The gating nozzle is a hollow structure with two open ends, consisting of a first section (conical) and a second section (cylindrical) connected from top to bottom, with their inner walls forming the gating channel. The first section occupies 2 / 3 of the total height of the gating nozzle, with a larger diameter at the top and a smaller diameter at the bottom for easy installation and replacement; the second section is cylindrical and directly connects to the ingot mold. However, existing gating nozzles suffer from poor structural strength, resulting in insufficient durability and consequently affecting their service life.
