heated furnace rolls shafts before fabrication by Qingdao Hexin Machinery Co.,Ltd.
heated furnace rolls shafts before fabrication:
Our company produces the furnace roller in ranging from 100mm to 500mm on diameter, rollers adopt centrifugal casting and precise casting technology on bell mouth, shaft head of forgings.Adoption of advanced production technology, so the furnace roller is equipped with high temperature resistance, corrosion resistance, resistance to wear, etc.
Horizontal furnace annealing furnace roller,Vertical annealing furnace furnace roller:
Used for continuous annealing line and galvanizing line horizontal annealing furnace, under the hydrogen nitrogen protective environment, the furnace temperature is about 700℃--1000℃，to complete heat treatment process by transporting lenient plate with even rapid，the diameter is 100--500mm,centrifugal casting for roll body, precision casting for journal and end bell, forging for shaft head.
Common used steel number is: shaft head (SUS304, 1Cr18Ni9Ti etc ),roll body and bell end ( ZG30Cr26Ni12、ZG40Cr25Ni20Si2 ).
