Body has a higher surface hardness.As the outer centrifugal casting,the hardness drop should be less than static cast roll.The strength of the core will be higher than the other cast roll. |
Product Description
Alloy ductile iron roll is characterized by the ball-shaped graphite in the matrix, through adjusting the compositions of Ni, Cr, Mo adopting different heat treatment technology, pearlitic ductile iron and acicular constitution and different performance of anti-heat impact and resistance to wear.
Qingdao XinShengYuan Roller Co.,Ltd is located in the haibin industry development zone in Qingdao. next to the Port of QingDao and expressway, conventient transportation. It covers an area of 20000 square meters, invested tens of millions RMB for construction. the company specializes in producing various types of hot -milled olled and cold-milled alloy rollers, catering to the needs of different industries in the domestic and international roller market, and is committed to building a high-quality roller manufacturing and research and development base in China. Forming a production capacity of 10000 tons of high-quality rolling rolls per year.
our company adopt advanced centrifugal compound casting technology for rolls making,and has researched and establsihed a series of high quality rollers, the main products are chilled cast iron rolls, infinite chilled cast iron rolls, ductile iron rolls, high chromium cast iron rolls, semi-steel composite rolls, centrifugal composite rolls, semi-high-speed steel and high-speed steel rolls, It can meet the application of different rolling mills and is suitable for rolling of various bars, wires, strips and profiles .Besides, the company insist on "first-class equipment, first-class technology, first-class management team " as the basic developing objectives, while we has been well equipped with the Advanced large-scale horizontal centrifuge machinery , sets of themedium frequency furnace and over 30 sets of advanced processing equipment like the lathe, grinding ,drilling and milling machinne etc, Furthermore,the company also has equipped the world-advanced equipment for the quality control and new roller invented such as heat treatment , spectrometer and temperature control etc. the company had attracted a number of R & D talents which have years of manufacturing roller experience and formed a efficient and professional management team that contribute to lay a solid foundation for rapidly development of "XinShengYuan Roller" .
