1.4 Main motor: 45KW-6 energy-saving AC motor
1.5 Roller speed ratio: (front: rear) 1:1.27
1.6 Roller linear speed: before (design value): 19.3m/min
2.1 Roller group:
2.1.1 Type: front and rear rolls are hollow. 1 each
2.1.2 Material: alloy chilled cast iron (LTG-H), which is subject to precision grinding after tempering.
2.1.3 Hardness of working surface: HS: 70 ± 2
2.1.4 A strong spring is installed between the bearing pedestals on both sides of the roller, which springs with the distance adjustment, effectively avoiding the gap between the distance adjustment screw and the roller, and preventing collisions. 2 groups
2.1.5 Double row self-aligning roller bearing is adopted. (Origin: Wafangdian) Group 4

2.1.7 The bearing seat cover is made of iron and attached with labyrinth ring oil seal, and there is no oil leakage inside and outside. 4 groups
2.1.8 Rotary joint for roller heating and cooling is attached with stainless steel metal hose. 2 groups
2.2 Base and rack
2.2.1 The substructure is welded with H-shaped steel, tempered and machined. 1
2.2.2 The frame is welded with steel plates and processed after tempering treatment, 2 groups
2.2.3 One stainless steel bowl
2.3 Roller gap adjustment device
2.3.1 Adjustment range: 0.8~10mm
2.3.2 Distance adjustment mode: manual distance adjustment
2.3.3 Electrical control: linkage, single action and inching can be realized to make the distance between two ends of the roller consistent during adjustment.
2.4 Rubber baffle group: hydraulic rubber baffle
2.4.1 Distance adjustment mode: hydraulic distance adjustment and electrical control can realize linkage and single action.
