LCC KR3 Series (w: 50 ~ 400 mm, t: 0.3 ~ 3.2 mm)
The vastly improved KR3 Series straighteners/feeders incorporate great new features, including a maximum material width of 300 mm, and 11 work rolls that give coiled materials a high degree of flatness.
■Productivity is increased by 30% (compared to conventional equipment)
Release-follow Speed MAX. 120SPM
Line Speed MAX. 16m/min
■Stock application performance is increased
Stock Width MAX. 400mm
Coil Weight MAX. 2,500kg
Features
- ■ Features(1) : 11 Work Rolls
-
The new KR’s ability to provide superior flatness comes from 6 upper and 5 lower work rolls with a diameter of 48mm(1.8″) each, contributing to highly precise coil processing.
- ■ Features(2) : Top and Bottom Work Roll Opening
-
The work rolls on the new KR can be reached from either the top or the bottom of the structure just by opening the cover, making cleaning the rolls much easier than on previous models. The upper door features an easy one-step button for opening and the lower door can be opened at 90 degrees.
- ■ Features(3) : Uncoiler
-
The KR’s inverter system controls the variable speed of the uncoiler, causing starting and stopping functions to be gentle, so that scratches and other imperfections in the material caused by sudden stops and starts are minimized.
- ■ Features(4) : TP-CCS Controller
-
A wide variety of information needed for planning, operation, maintenance, etc. is uniformly controlled under the base mode of “Settings, Planning, Operaion, and Maintenance”. Equipped with various new operations, it is a complete operation system that responds to diversification and sophistication of merchandise and reduction of work time.
