Mandrel bar plays a crucial role in producing large diameter seamless pipes in modern industries. In production line, it have to bear strong and complicate stretch, compressing touching stress and high temperature cold-hot yield stress under high speed cycling. Under these circumstance, chemical components, mechanical propertied, no-metallic inclusion, grain size, microstructure, ultrasonic test, size precision, surface finish, all these factories of steel are required very strictly. Mandrel bar is made from H13(4Cr5MoSiV1),
With annual output of 15 thousand tons, its quality and service life have reached to world level of that. Our company is capable of producing a series of mandrel, such as MPM, PQF, FQM, with the diameter of 80~350mm, the length of 2500-17500mm.
Equipment advantage: steel making (EBT+LF(VD)+ESR)-forging(formed by hydraulic press machine + forged by rotary forging machine)-annealing-rough machining ¨Cmagnetic test-heat treatment-ultrasonic test-finish machining-chrome plating-thread phosphating.

Alloy chilled cast iron rolls are one kind of cast iron rolls, which contain almost no free graphite in the matrix of working layer of the barrel. They have hardness and excellent wearabillity, are suitable to finish stands of light bar and wire rolling mills and narrow strip mills. Its microstructure is fine pearlite and carbides.

Copper mould tube
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 steel 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-Ag0.1 & 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.
- Taper design:
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 .
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 user¡¯s 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.
