Product Description Continuous Casting Machine Continuous casting machine (CCM) is a method of producing an infinite solid strand from liquid steel bycontinuously solidifying it as it moves through a CCM. It is the predominant process route in a modern steelplant which links steel making and hot rolling. A typical section and plan view of a CCM is shown in Fig 1. Fig 1 Typical section and plan view of a CC machineTypes of continuous casting machinesCC machines have evolved from the strictly vertical type of machine to curved machines in order to limit theinstallation height while still using high casting speeds. In recent years, CC machines of more sophisticatedmechanical design are being constructed. These machines apply several techniques for achieving highercasting speeds and higher outputs and are with progressive straightening or progressive bending over aliquid core. Simple vertical CC machine with a straight mould and cutoff in the vertical positionVertical CC machine with a straight mould along with single point bending and straighteningVertical CC machine with a straight mould along with progressive bending and straighteningBow type machine with curved mould and straighteningBow type machine with curved mould and progressive straighteningIn all cases, the bending and straightening is usually carried out in one or several steps. Multistep bendingand straightening reduces the mechanical stresses and reduces the risk of strand cracking. The first CCmachine which was built up for CC of liquid steel was a simple vertical CC machine. Then later thedevelopment led to many kinds of CC machines with various ways of bending and straightening. The mainobjective for these developments have been to construct lower and simpler CC machines with smaller needfor space, lower investment costs, and high flexibility in production and maintenance. One of the main issueswith a vertical CC machine is that the distance between the mould and the point of cutting is limited. Due tothis the casting speed is low and low speed means low production rate. The advantage of the vertical CCmachine is that there is no bending or straightening of the strand. In the case of large strand sizes, the stresscaused by the ferrostatic pressure of the liquid steel inside the strand can lead to bulging of the solidifiedstrand shell.The high bulging can lead to the formation of severe defects like segregations and cracking. It istherefore very important to support the strand sufficiently to avoid bulging. The higher is the machine, thebigger is the risk for bulging. This is also one reason for the development of the lower machines, i.e., bent orbow-type casters.One important characteristic in continuous casting is the removal of nonmetallic inclusions from the liquid steel.Owing to their lower density compared to the liquid steel, the inclusions are able to float up from the liquid. Inthe straight CC machines, the inclusions can float up more easily to the meniscus (liquid surface near themould wall) than in the bow type CC machines. This is because in the bow type CC machines some inclusionscan attach to the inner arc of the strand shell, when they are flowing up. This can be seen as a higher amountof inclusions but also as an uneven distribution of the inclusions in the as cast strand. So, the vertical or verticalbending type CC machines have the advantage that inclusions can float up better to the meniscus than in bowtype CC machines. These days, the most common CC machine type is the bow type with curved mould. Thestrand leaves this curved mold in an arc without the need for bending after the mould and just with straighteningat the lower part of the CC machine. In the case of larger strand, especially with slabs, also vertical bending CCmachines are today more and more popular, because of the increasing need for cleanness.It is anyhow important to know that many things other than the CC machine design affect the cleanness and steelquality.The CC machines are normally named according to the strand dimensions such as billet, bloom, and slabCC machines etc. There are also CC machines to cast rounds and other shapes like beam blanks.Specification and Technical ParameterMain ParameterR2.25MR4MR5.25MR6MPower95KWBillet Size60-70 square80-125 square125-150 square150-180squareFlowOne flow or multi-flow according to customer's requirementsWorking SpeedAdjustable.
