The high temperature molten steel continuously cast into the production process has a certain shape and a certain cross-sectional dimensions called slab continuous casting.
The equipment needed to complete this process called continuous casting equipment. Pouring steel equipment, continuous casting machine body of the device, the cutting area of the device, hydraulic integration dummy bar collection and delivery device constitutes the core part of the continuous casting equipment, casting machine called habits.
Caster can be classified in several forms. In terms of the structure shape it can be divided into vertical continuous casting machine casting machine, vertical bending caster with a straight segment curved continuous casting machine, arc continuous casting machine, multi-radius oval horizontal continuous casting and continuous casting machine machine. With the development of continuous casting technology, has launched a caster wheel, especially on thin slab caster.
If you follow the caster cast sectional size and shape to distinguish, it can be divided into slab continuous casting machine casting machine, billet caster, bloom caster, the round billet caster, profiled section caster and a thin slab caster. In billet caster also includes a rectangular billet continuous casting machine, usually casting section or equivalent cross-sectional area larger than 200 × 200mm billet called bloom, section or equivalent cross-sectional area less than 160 × 160mm billet slab of petit , thickness ratio greater than 3 rectangular billet called slabs.
If the slab continuous casting machine according to the number of streams in a common casting ladle can be distinguished, it can be divided into single-stream, or double-strand caster.
When breaking the traditional concepts to advanced digital technology to replace the traditional control thought, not only showed the ability to achieve superb technology, but because of the nature of changes in the structure, so that its implementation of traditional systems can not be achieved without the need for complex system designs, parameter setting and adjustment repeatedly, but not because of long-running performance change occurs,
Casting machine from a digital level control, digital line width adjustment (slab), a digital non-sinusoidal vibration, the number two cold water control, digital online soft reduction, continuous casting machine in the process of digitizing all, simple design, high level of technology , low cost, low risk investment advantages you will appreciate sincere.
Hydraulic vibration control system through the six million consecutive vibration test, the test results fully in line with actual production data needs, and equipment intact. Since Bo Billion US adopts the international advanced digital hydraulic cylinder seal structure design, which not only does not have any leaks, seal life is also greatly improved, making the system operating costs far lower than the mechanical vibration system. Mold wall motion solidified shell friction is considered to be torn further solidified shell casting speed limit fundamental factors. The presence of a liquid slag film between the initial shell and the mold wall friction here is viscous friction, ie the friction force is proportional to the relative velocity, the viscosity of the slag film and inversely proportional to the thickness of the slag film. Thus during mold oscillation positive slippage of the friction and tensile stresses on the solidified shell due to large initial shell may crack, for the development of non-sinusoidal vibration technology to reduce this friction. Theory and simulation results show that properly selected non-sinusoidal oscillation parameters (skewness) can reduce friction by 50% to 60%. Billion US Bo technology will transform a simple ordinary caster achieve 400 hydraulic vibration, deflection rate of 50%, and the line can be casting machine adjusted. Is to achieve high quality, high yield caster adapt new technologies.
