  • Description Detail:High chromium cast iron roller by centrifugal casting, Bimetal composite vertical roller, Bimetal composite roller

The characteristics of High chromium cast iron roller by centrifugal casting.    
 
1、采用离心双金属复合铸造工艺。
Using bi-metal composite centrifugal casting technology.
 
2、离心铸造利用离心力无气孔、无夹杂。
The centrifugal casting without pores and inclusions by using centrifugal force.
 
3、金属模具快速降温金属组织致密,提高耐磨性。
Fast cooling metal mold making the casting have a compact microstructure to
improve wear resistance.
 
4、 辊套外层高铬铸铁,内层我们采用合金球铁或合金钢(具有很高的强度和韧性)。 
Using high chromium cast iron(Cr17NiMo,Cr18Ni2,etc) to the out layer of roller,
using alloy ductile iron like GGG400 etc or alloy steel like 35CrNiMo etc at inner
layer (with high strength and toughness).
 
5、根据使用要求,设计了合理的使用层厚度,减少了合金用量,降低了成本。
By reasonable wear resistant layer thickness design according to client’s requirement
to reduce the dosage of alloy and the cost.
