Abstract

This utility model discloses a high-efficiency low-nitrogen manganese ingot casting and molding device, relating to the field of casting mold technology. It aims to solve the technical problem of current manganese ingot casting and molding devices where the surface of the injected liquid manganese has a high contact area with air, leading to excessive combination with nitrogen in the air during the gradual cooling process. This results in excessive manganese-nitrogen compounds in the low-nitrogen manganese ingot, causing excessive nitrogen content. The device includes a molding mold with lifting structures at the top of both sides of its outer edge. The molding mold also has an inverted frustum-shaped molding cavity for cooling and molding the liquid manganese. This utility model uses an inverted frustum-shaped molding cavity, significantly reducing the contact area between the liquid manganese and air, thereby reducing the problem of excessive combination with nitrogen in the air during the cooling process and effectively ensuring the nitrogen content standard in the low-nitrogen manganese ingot.
