CCM Machine Copper Mould Tube Square 190mm DHP Continuous Billet Caster

   Copper mould tube is one of the core equipments of ccm continuous billet caster. It makes high temperature liquid steel solidify and crystallize rapidly to form steel castings. After electromagnetic induction stirring, the liquid steel in the copper mould is cooled and shaped, and then the casting is pulled out, and then the slab is divided into predetermined length by flame cutting machine ( Torch Cutting Machine).The molten steel is directly cast in the mold copper tube, and the steel billet is continuously cooled and formed in the copper tube. In order to solve the problem that the copper tube is in contact with the cooled billet shell and separated from time to time during the working process, the mold copper tube is still bent to one side Square or rectangular copper tube, the inner cavity of the copper tube is tapered from the upper mouth to the lower mouth, and the inner cavity of the copper tube is a double-cone or tri-cone or multi-cone, or a parabolic cavity from the upper mouth to the lower mouth. Shape, the taper of the upper section or the upper part is greater than the taper of the lower section or the lower part. It is best that the taper of the straight surface is greater than the taper of the curved surface. Avoid the air gap between the blank shell and the inner wall of the copper tube during the working process, which is more in line with the contraction change law of the blank shell.

 

The main components of the automatic control system for continuous casting include the speed control of casting roller, the control of mold vibration frequency, the control of fixed length cutting and other automatic control technologies.
