Description

Technical Field

[0001] The utility model belongs to the technical field of iron and steel metallurgy, and in particular relates to a water-cooled steel ingot mould. Background Art

[0002] The water-cooled ingot mold is a mold used for casting steel ingots. Its main feature is that it has a water-cooling structure. A water cooling channel is usually set inside the ingot mold. In this way, during the casting process of the steel ingot, the heat is taken away by the circulation of water, thereby accelerating the cooling speed of the steel ingot, helping to improve the solidification structure and quality of the steel ingot, reduce defects such as segregation, and improve the performance of the steel ingot. At the same time, the water-cooled ingot mold can also improve production efficiency and reduce production cycle to a certain extent;

[0003] However, the existing circular ingot mold has a high height after casting and a small diameter, which makes it inconvenient to demold the closed casting work. Therefore, in order to facilitate the demolding of the steel ingot cast in the ingot mold, a double-open ingot mold is required. The double-open ingot mold is composed of a circular mold body for casting by splicing. When demolding, the two semicircular molds can be separated to facilitate demolding. The water-cooling pipeline of the existing water-cooled ingot mold is connected and circulated in the mold body. Since the double-open ingot mold is composed of two groups of mold bodies, it is more expensive to use a water cooling device for the pipelines in the two mold bodies separately. The vibration during demolding is not easy to ensure the docking between the pipelines, which can easily cause greater wear on the pipeline docking seals, which is not conducive to the service life of the double-open ingot mold. Therefore, it is not conducive to using a water cooling device on the double-open ingot mold to assist in casting of steel ingots. Utility Model Content
