vertical annealing furnace roller by Qingdao Hexin Machinery Co.,Ltd.
vertical annealing furnace roller:
My company has many years of mature technology and technical accumulation in the field of furnace roller production , the different working condition of the with alloy material is used to ensure the quality of the furnace roller, excellent performance. Steel grades with commonly used : shaft head (SUS304, 1 cr18ni9ti, etc.), roll neck and shaft neck (ZG30Cr26Ni12, ZG40Cr25Ni20Si2)
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 ).
