stainless steel cast rolls by Qingdao Hexin Machinery Co.,Ltd.
stainless steel cast rolls:
Qingdao Hexing machinery co., LTD produces furnace roller roller with stable performance, leading technology, furnace roller adopts the centrifugal casting, precise casting technology on bell mouth, shaft head of forgings. We Optimize the furnace roll roughness to reduce furnace roll wear and strip defects such as scratch, only in this way can they increase the service life of the 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 ).
