  • Description Detail:Roller in High Cr+ ZTA Ceramic + GGG composite centrifugal, ceramic composite castings,metal matrix ceramic composite casting

The characteristics of High chromium cast iron  + ZTA ceramic  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)+ZTA ceramic  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).
