cast rolls under solution heat treatment by Qingdao Hexin Machinery Co.,Ltd.

 cast rolls under solution heat treatment:

    Our company is specializing in producing horizontal roller annealing furnace furnace, vertical annealing furnace roller.They are mainly used for the refund, galvanizing line horizontal annealing furnace, furnace roll under hydrogen nitrogen protective atmosphere, furnace temperature ranges from 700 to 1000 degrees, even it can rapidly transport  the strip` annealing process.Steel plate makes solution treatment, the treatment such as normalizing, annealing, furnace roll must be equipped with  high heat resistance, high temperature characteristics of bearing capacity.

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 rapidthe 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 ( ZG30Cr26Ni12ZG40Cr25Ni20Si2 ).
