We produce the kinds of Tungsten Carbide Roll Rings used in the cold rolling of Reinforced and smooth wire mesh. Profiling rolls are supplied in accordance to possible international standard, and can be provided chamfered by machine, hand or sand blasting as well as with specific customers' marks. descaling rolls with tungsten carbide inserts are designed and manufactured, tailored on the spcific customers' needs and euqipment. High quality precision roll holder are produced for standard and special equipment. Special customized rolls can be provided in the most suitable Tungsten Carbide grade.
When the roll rings are used in the machines for reducing with tension the diameters od steel tubes, the lifetime of Tungsten Carbide Roll Rings is 20~50 times that of Cast Iron Roll Rings and the surface conditions and precision of dimensions of steel tubes is greatly improved.
"AT Carbide "Tungsten Carbide Roll Rings:
Excellent performance for hot rolling;
Wide Selection of standard and customized grades available from intermediate to finishing;
Customized design availbale with various size up to 520 mm;
Applicable to all kinds of rolling mills for deformed bar, wire rod and flat bar, ;
Various type of rolls available including pinch roll and guide rollers;
Excellent and Homogenous mircostructure as a result of simultaneous process of sintering and HIP furance;
Excellent resistance to wear and thermal fatigue contributing to cost saving and increasing productivity for customers.
Recommendation:
Sufficient cooling capacity is essential to reduce roll ring's thermal fatigue and stress which cause crack and damage in roll rings.
Temperature is recommended to be below 20~ 30 centigrade
Presure of cooling water is recommend to be 5~6 bar
Cooling Water is Jetted in a radial direction and at least half of the roll circumstance is cooled by spray jets with a water volume around 30m3/h
The items can be made according to your own specification, please feel free to contact us.
