hearth rollers for high temperature furnaces by Qingdao Hexin Machinery Co.,Ltd.
hearth rollers for high temperature furnaces:
My company produces retreating, galvanizing line furnace roll of horizontal annealing furnace , rollers adopt the centrifugal casting and precision casting technology on bell mouth, shaft head of forgings.Under hydrogen nitrogen protective atmosphere furnace roller, furnace temperature range from 700 to 1000 degrees, we can evenly and rapidly transport strip annealing process.
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 ).
