Square Billets / Round Billets Continuous Casting Machine

Square Billets / Round Billets ContinuousCasting Machine

Thesquare billets/round billets continuous casting machine is a fully arc typesquare or round billet caster used to cast optimal carbon low allow steel, like20~45#, and alloy steel, such as, 20Cr~40Cr, 20CrMo~40CrMo, 20CrMnTi and 45Mn2.

This square billets/roundbillets continuous casting machine can cast 4 strands of billetssimultaneously. And the billets are automatically cut by the flame.Furthermore, the rigid dummy bar is adopted in the casting of a billet in aprotective way. And the billet is moved via the hydraulic steel turning machineand mechanical steel moving machine.

Crystallizer
The square billets/round billets continuous casting machine is equippedwith 4 crystallizers measuring130mm×130mm. And thesecrystallizers are fabricated with a pair of foot roller and a spray pipe. Also,the copper pipe is made of phosphorizedcopper with a chrome-plated inner surface. There is a reserved installationposition for level control. And each crystallizer has one protective shieldstructured with welded steel, one vibration device featuring double eccentricleaf spring, sinusoidal vibration and inner arc side layout. Also, the castingoperation box is supported by a removable construction for convenientoperation.
