3. Structure Specification
3.1 Body
(1)Body frame: Welded into shape, after annealing, overall processed through precise machine tool, high rigidity, not easy becoming deformed, smooth, wear-resisting.
(2)Base: Welded base, after annealing and machining, high rigidity, won't deform easily.

3.2 Rolls and Bearing Group
(1) Roll Structure:hollow smooth rolls
(2) Material: Alloy cold harden cast iron LTH-H
(3) Hardness:68-72HSD
(4) Cold Harden Layer:10-25mm
(5) Main Bearing: cylindrical roller bearings (Wafangdian Metallurgy Bearing)
(6)Bearing seats adopts cast iron (FC30), made from tempering handling. Excellent intensity and precision, together with lubrication oil holes. The bearing seats are made of aluminum with labyrinth ring oil seals to keep from oil leaking of inside and outside.
(7)Rolls nip has max. nip protecting function.
(8)Rolls temperature adjusting adopts high quality revolving joint and stainless metal pipe.
