Alloy Spheroidal Graphite Iron Rolls

Equipped with one of the best alloy spheroidal graphite iron rolls brands, Kaida Roll Group is one of competitive alloy spheroidal graphite iron rolls manufacturers and suppliers in China, welcome to visit our website.

Alloy Nodular Cast Iron Rolls (SG)

These rolls are characterized by spherical graphite.Its mechanical properties are similar to that of alloy indefinite chilled rolls except that its strength is higher than the latter.They can be produced by static casting.

Speaking of static casting, there’re two type of static process

No.1, Monobloc Static Cast Roll

Definition:   

-Single pour casting rolls employ the same chemical content, i.e. Barrel and Neck.

-To achieve the different requirement of hardness, strength, and metallurgy by the means of controlling the freezing rate of molten iron

Material Application:

Pros and Cons:

No.2, Composite Static Cast Roll

Step 1, molten iron pours into outer shell

Step 2, after solidification of outer shell molten iron; add molten iron to the core, the overflow molten iron can be reclaimed.

Definition:

-The chemical content of barrel work layer is different from core and neck

-The properties of this type of rolls depends on chemical content, the cooling rate of both are also critical    

Pros and Cons:
