Additionally, by incorporating the traditional casting process in certain stages, it can achieve superior casting properties and surface quality.

In the semi-continuous casting procedure, the caster typically serves as the central equipment of the entire production line. It can accomplish high-speed casting, continuous gear adjustment, automatic control, and other functions through continuous casting technology, thereby improving production efficiency and product quality. Simultaneously, the hydrostatic bed or static sand bed, which are process equipment of the iron casting process, can be adjusted and controlled locally based on specific casting requirements to achieve better casting performance.

In essence, semi-continuous casting merges the benefits of continuous casting technology and traditional casting technology, enabling high-efficiency and high-quality casting production. It has found extensive application in engineering practice, particularly for large and complex structure castings, due to its excellent adaptability and cost-effectiveness.

Semi-continuous casting is a process that has found extensive application in various industries due to its excellent adaptability and cost-effectiveness. Here are some of its applications:

1. Steel Industry: Semi-continuous casting is used in the steel industry, particularly for high-alloy specialty steel with large section sizes¹. It offers advantages such as higher yield, reduced processing, and enhanced quality. The process involves pouring the melt into a mold with a lowering bottom plate. When the length of the partly solidified slab reaches the required value, the lowering plate is stopped. The slab then solidifies, similar to ingot casting.

2. Non-Ferrous Metals: For casting of non-ferrous metals such as aluminum and copper, semi-continuous casting is a standard application. The process involves casting one or two ladles on one or more strands into long blooms. The strand is held in position until final solidification is achieved, which can extend over many hours depending on the section size.

3. Manufacture of Semi-Finished Products: The continuous casting process is a very effective method to manufacture semi-finished products such as bars, profiles, slabs, strips, and tubes made from steel and non-ferrous metals such as copper, aluminum, and their alloys.

4. Casting of Special Shapes: The process is used primarily to cast round extrusion billets, rectangular rolling slabs, square wirebars, and forging stock and special shapes, such as T-ingot.

In summary, semi-continuous casting is a versatile process used across various industries for the production of a wide range of products. It combines the advantages of both ingot and continuous casting, making it a practical and cost-effective solution.
