High Efficient Continuous Casting Technology

Precision, mold oscillation device longevity is one of the key technologies and efficient continuous casting, which includes vibration device software optimization and hardware in the form of mold oscillation and vibration optimization of process parameters. In the past half-leaf springs used in efficient continuous casting, the whole leaf springs and high-frequency small-amplitude sine wave frequency played a positive effect. Currently, MCC developed a new series casting full-leaf spring vibration device, its higher accuracy, enhance the overall stiffness, long life, to promote the further development of efficient continuous casting will play an important role. The device can be used hydraulic transmission or mechanical transmission, hydraulic transmission can increase the positive strip time, the amount of slag to improve protection and reduce the vibration speed of the peak, reducing the casting resistance, reducing the negative strip time, so that oscillation mark depth is reduced accordingly. Mechanical transmission can reduce costs, promote the use of more easily.   As we all know, powder and casting speed to match the casting speed increased to protect the slag viscosity index corresponding improvement to ensure that the amount of the allowable range diminished or reduced in order to ensure the high quality of the slab. Therefore, we must have a low viscosity, low melting point, high melting speed, large fluxes of coagulation factor after casting efficient. Flux efficient continuous casting technology is a key technology. Secondary cooling hardware and software technology which is also one of the key technologies of efficient continuous casting, its hardware requirements as far as possible uniform cooling (barrier spray) and can be easily adjusted. At present, because the market for steel, stainless steel and carbon steel pipe varieties of high quality standards, the new continuous casting machine tends to increase the radius of the curved slab tends to transform straight curved continuous casting machine, its purpose is to make from the crystallization is the two-round slab of cold forming symmetrical or nearly symmetrical solidification solidification process, in order to obtain high-quality billet. In recent years, boards, billet caster dynamic secondary cooling water cooling automatic control has been rapid development, software development more practical, the applicability of various kinds of steel, different casting speed, different temperature changes can be timely adjusting the amount of water to produce high-quality slab. According to the slab with a liquid core straightening mechanism to select three parabolic curve as a continuous caster straightening curved and straight segments, played a good result in the efficient and continuous casting. Currently they have tended to adopt soft reduction technology to reduce segregation, shrinkage, improve casting quality. Billet used in thermal compression technology to replace under light pressure, also achieved satisfactory results. High efficient continuous casting technology is often used for seamless steel pipe manufacturing.
