CCM ‐ GENERAL PLAN VIEW
CCM ‐ SIDE VIEW
CCM ‐ DESIGN CONCEPT
According to customer request, CCM can be equipped with the necessary modern equipment to produce high quality casted products, such as tundish of delta type to reduce inclusions in the mould, long copper tube to improve primary cooling on the billet surface, automatic mould level control system, high casting radius to reduce stress during unbending, secondary spray cooling divided in three zone for a better cooling effect and control, walking beam cooling bed for the straightening of the long billets.
CCM ‐ SAMPLE PROJECT
CCM ‐ DESIGN CONCEPT
 CCM can be designed to produce square billets in the sections between 100 to 200 mm² and
blooms between 180 to 260 mm².
 Special designs for beam blank and round sections between 160 to 440 mm can be done.
 Radius of 5‐12 m and mould length of 750‐1000 mm can be designed according to project
requirement.
requirement
 For some special casting,
casting vertical continuous casting application can be considered.
considered
 The CCM can be fitted with up to eight casting strands in order to satisfy the production schedule
given by the EAF.
