Heat resistant sink rolls Used for Continuous Hot DIP Galvanizing Line to get high qualified galvanized products.
In the metallurgy industry, in order to get high qualified galvanized products, sink rolls play very important role in the continuous hot dip galvanizing line. Sink roll is one of the three rolls in CGL (continuous galvanizing line); Along with other two rolls, stabilizer roller and back-up roller, they are the main composition of continuous galvanizing line.
Materials:316L,317L,316,HK,HT,HU,HP,HH,22H,HF,Super 22H etc.
Diameter: Mainly100-1600mm, or as requirements.
Process: Centrifugal casting Sink roll body, static casting Cone.
Working condition
Working temperature is 500ºC-700ºC. It plays a turning role the whole sink roll assembly. In the process of production, the whole sink roll is immersed into molten zinc liquid. Cooperated with stabilizer roll, agitating molten zinc liquid to the surface of plate. The surface structure and quality of the sinking roller will directly affect the galvanizing quality of the sheet and affect its service life. Therefore, the sinking roller is one of the key factors determining the production quality and production efficiency of the galvanizing line.
