Copper mould is placed in the heart position of continuous casting machine(CCM),its function is to solidify the liquid steel pouring through the Submerged entry nozzle(SEN), guarantees required billet/bloom/slab with enough thick shell to be obtained. Copper mould plays a crucial role in increasing con-casting efficiency as well as improving billet/bloom/slab quality.
Mould material :The tough working condition of copper mould tube requires its material with excellent tensile strength, enough hardness, low elongation & good thermal conductivity. After many years experiment in our Lab & steel mills, now we are manufacturing copper mould tube with widely accepted material as :SF-CU, Cu-Ag0.1P & Cu-Cr-Zr.
Mould plating :The temperature inside the mould is very high, so in order to prevent inside wall from wearing off & eliminating cracks & defects on the billet surface, by introducing western plating technology, ANSSEN has successfully improved the coalescent strength between copper and plating, as a result, life of copper mould has been elongated by 20~30% compared with traditional ways.
Typical coatings are : Cr, Ni, Cr-Ni, Ni-Fe, Ni-Co.
Properly taper design will make billet shrinking in a proper curve while passing through, also minimizing the air gap between copper mould & billet Shell.
Along with the development of con-casting technology, ANSSEN has accumulated rich experience in taper designing, our tapers are: Single taper, double taper, triple taper, multiple taper, parabolic taper as well as double parabolic taper & convex.
ANSSEN is an iron-steel industry oriented group who is committed itself to the technology research and development for various metallurgical equipments, one of our key products is continuous casting equipments and its spare parts that is used as an vital items for steel makers.
ANSSEN mission is to manufacture Europe quality Copper moulds at a more competitive price by introducing advanced technologies and combination with powerful institute to decrease users cost and increase efficiency.
ANSSEN is one of the earliest companies who starts manufacturing & technical research in China for copper moulds, with an area of 60000 square meter,500 workers, 80 technicians, and 27 engineers, main advanced equipment of 300sets, as well as 2 decades of experience, now our annual production capacity reach 20000pcs, which make us deeply rooted in our industry.
