Main character

SY610-4Γ1830 type four roller calender and auxiliary equipment

A.   Calender (host machine)

1.    Calender: feed material from top and make final production from bottom, roller diameter 610 mm, roller surface width 1830mm, the surrounding drilling and oil heating, line speed of the calender 5-50m/min. The piece coming out from the roller of the calender has display apparatus gap of rollers distance. Right driving.

Rollers

2.    1# and 2# rolls are cold-cast alloy roller and surrounding drilling, surface hardness HS68-74 ° C, the rollers’ surface hard chromium plating fine grinding, coating thickness 0.1mm, the rollers surface roughness Ra = 0.05μ, surface comprehensive precision 0.01mm;

Material of 3# and 4# rollers is alloy forging flaw detection processing, the rolls’ surface hard chrome plating, coating thickness 0.18mm, hardness> HRC60 ° roll, surface roughness Ra = 0.01μ, surface comprehensive precision 0.05mm, roll surface temperature no less than 230 ° C, the roll surface temperature error ± 1 ° C;

1-4# rollers surface had no middle height, 1-4 # rollers all surrounding drilling, roller surface chromium plating without pinhole, the roller polished and process degassing after fine grinding.

3# and 4# rollers hard chrome plating after hot mill processing.

Bearing

3.    Bearing use the Wafangdian production taper bearing, bearing pedestal use ductile iron.

Transmission and power

4.    Drive power of 1# roller and 4# roller of Calender: 55KW (in this calender main and auxiliary equipment use AC motor), and the remaining 2# and 3# roll: 75KW power. Main and auxiliary can tune speed by linkage and also division. (Calender is equipped with blackout emergency opening device, UPS devices purchased by buyer). The motor of calender adopts AC motor speed regulation, Siemens Beide motor, Japan Yaskawa governor, other electricals adopt Shanghai Schneider.
