The production process of continuously casting high-temperature molten steel into a slab with a certain cross-sectional shape and a certain size is called continuous steel casting.
Continuous casting machines can be classified in many forms. According to the structure and shape, the continuous casting machine can be divided into vertical continuous casting machine, vertical bending continuous casting machine, arc continuous casting machine with straight section, arc continuous casting machine, multi-radius elliptical continuous casting machine, and horizontal continuous casting machine. With the development of continuous casting technology, research on wheeled continuous casting machines, especially thin slab continuous casting machines, has been carried out.
If it is distinguished according to the size and shape of the section cast by the continuous casting machine, the continuous casting machine can be divided into slab continuous casting machine, billet continuous casting machine, bloom continuous casting machine, round billet continuous casting machine, special-shaped section Continuous casters and thin slab casters. The billet continuous casting machine also includes the rectangular billet continuous casting machine. Usually, the casting section or the equivalent section area larger than 200×200mm is called the bloom, and the section or the equivalent section area is less than 160×160mm. , a rectangular blank with a width-thickness ratio greater than 3 is called a slab.
If it is distinguished by the number of strands that the continuous casting machine can cast under a common ladle, it can be divided into single-strand, double-strand, or multi-strand continuous casting machines.
Digital Continuous Casting Machine
Breaking through the traditional concept and replacing the traditional control idea with advanced digital technology, not only shows the superb technology realization ability but also because of the essential change of the structure, when it achieves the effect that the traditional system cannot achieve, there is no need for complex system design, Parameter setting and repeated adjustment will not cause performance changes due to long-term operation. Therefore, the digital continuous casting machine realizes digital liquid level control, digital online width adjustment (slab), digital non-sinusoidal vibration, and digital secondary cold water control. The advantages of simple design, high technology level, low cost, and low investment risk are obvious in the process of all digitalization of continuous casting machines.
Hydraulic Control of Continuous Casting Machine
The hydraulic vibration control system has passed 6 million consecutive vibration tests, the test data results fully meet the actual production requirements, and the equipment is intact. Because the Hani Metallurgy digital hydraulic cylinder adopts the international advanced sealing structure design, it not only does not produce any leakage but also greatly improves the life of the seal, making the system operating cost much lower than the mechanical vibration system.
The friction of the mold wall against the moving shell is considered to be the fundamental factor in tearing the shell and thus limiting the casting speed. There is a liquid slag film between the primary shell and the mold wall, and the friction here is viscous friction, that is, the friction force is proportional to the relative movement speed, and the viscosity of the slag film is inversely proportional to the thickness of the slag film. In this way, the friction force and the resulting tensile stress on the billet shell during the vibration and slippage of the mold are relatively large, which may crack the primary billet shell.
Therefore, a non-sinusoidal vibration technology was developed to reduce this friction force. Theoretical research and simulation experiments show that proper selection of non-sinusoidal vibration parameters (slope rate) can reduce friction by 50% to 60%. Hani Metallurgy has simply modified the ordinary continuous casting machine to achieve 400 hydraulic vibrations, the deflection rate reaches 50%, and can be adjusted online. It is a new technology for continuous casting machine transformation to achieve high quality and high output.
Digital System of Continuous Casting Machine
The dynamic soft reduction process allows the caster to control the final solidification stage, avoiding central loosening of the slab and minimizing segregation. Dynamic soft reduction produces slabs with the best intrinsic quality. As the principle of direct strip rolling from thin slabs continues to be successfully practiced around the world, steel companies producing high-quality products have begun to widely use soft reduction control technology.
Digital Slab Mold On-Line Width Adjustment Control System
Avoid frequent replacement of molds, improve the operation rate of continuous casting machines, and meet the needs of users with multiple specifications and small batches.
Digital Continuous Caster Mold Secondary Cold Water Control System
The digital control valve is adopted, which is directly controlled by PLC, which avoids the vibration and corresponding lag that are easy to occur in electric servo valve and pneumatic membrane valve, and accurately realizes the dynamic control of secondary cooling water. Water pipes, pumps, and sufficient water sources. The water cooling system of the continuous casting machine is mainly used to cool the billet rollers of the continuous casting machine.
Hani Metallurgy is a manufacturer of vertical continuous casting machines, vertical bending continuous casting machines, arc continuous casting machines with straight sections, arc continuous casting machines, multi-radius elliptical continuous casting machines, and horizontal continuous casting machines.
