Development history of continuous casting technology

The development of continuous casting technology has a history of over 100 years. The emergence of continuous casting technology is a major revolution in modern metallurgical technology, replacing mold casting with continuous casting, making large-scale steel production possible.

In summary, the development of continuous casting technology can be roughly divided into the following five stages:

The first stage (1840-1930)

The Enlightenment Stage of the Thought of Continuous Casting of Molten Metal

In 1840, Cyrus obtained a continuous lead casting patent

In 1856, Bessemer used a water-cooled rotating twin roll continuous casting machine to cast metal tin foil, lead plate, and glass plate, and obtained patents

The earliest suggestion (in 1887) for a continuous casting equipment similar to modern continuous casting machines was made by German Dylan, who developed equipment that included open crystallizers, liquid metal injection, secondary cooling sections, dummy bars, and billet cutting devices.

Phase II (1940-1949)

Development stage of continuous casting feature technology for steel

The experiment of continuous steel casting began in the 1940s. In 1943, Joan Hans built the first experimental continuous casting machine for molten steel in Germany.

The technical viewpoints proposed at that time, such as vibrating water-cooled crystallizers, submerged nozzles, and mold protectors, laid the foundation for modern continuous casting machines. Mold vibration has become a standard operation for continuous casting machines.

Phase III (1950s 1970s)

Industrialized application and mature stage of conventional continuous casting technology

During this period, continuous casting technology developed at an astonishing speed, with over 5000 patents and technologies related to continuous casting emerging, laying the foundation for modern continuous casting technology.
