Continuous casting machines can be divided into two categories according to whether the crystallizer moves: one is that with fixed crystallizer (including fixed vibrating crystallizer), such as vertical continuous casting machine, vertical bending CCM, arc shaped CCM, oval continuous casting machine, horizontal CCM, etc. The other type is that with synchronous motion crystallizer. The crystallizer of this model moves synchronously with the casting billet, and there is no relative movement between the casting billet and the wall of the mold.
Number of Units
A set of continuous steel casting equipment that shares one ladle and pours one or more strands of billet is called a continuous casting machine.
The unit has an independent transmission system and an independent working system. When other units break down, a group of continuous steel casting equipment that the unit can still work as usual is called a unit. A continuous casting machine can consist of one unit or several units.
The total number of billets that a continuous casting machine can pour at the same time is called the flow number of the CCM. A continuous casting machine has 1 unit, and can only cast 1 billet, which is called 1 machine 1 flow; if one has multiple units, and can cast multiple billets at the same time, it is called multi-casting machine. One machine with multiple flows; one unit that can cast two billets at the same time is called 1 machine with 2 flows.
Simplified and Shorten the Process
Processes such as de-molding and preparing the mold are omitted. As a result, about 40% of infrastructure investment costs can be saved, the floor area can be reduced by about 30%, and labor force can be saved by about 70%.
Increased Metal Recovery Rate
Using the permanent mold casting process, from molten steel to billet, the metal recovery rate is 84%-88%, while the continuous casting process is 95%-96%, and the metal recovery rate is increased by 10%-14%.
Reduced Energy Consumption
The continuous casting process can save energy by 1/4-1/2 compared with the traditional process.
The Production Process Is Mechanized and Highly Automated
The improvement of equipment and operation level and the use of computer management throughout the process not only fundamentally improved the working environment, but also greatly increased labor productivity.
Improved Billet Quality and Expand Product Variety
Almost all steel types can be produced by continuous casting process, such as ultra-purity steel, silicon steel, alloy steel, tool steel, etc., about 500 steel types can be produced by continuous casting process, and the quality is very good.
The application of continuous casting machines has made the iron and steel industry develop rapidly in the world. With the development of the industry, continuous casting technology is gradually becoming mature.
