Silicon Steel Coil Coater (Roll Coater for CA / DCL / FCL Lines)

A high-speed roll coater engineered for continuous silicon steel processing lines — applicable to CA Line (Continuous Annealing Coating), DCL Line (Decarburization Annealing Coating) and FCL Line (Final / Hot Leveling Coating). It applies insulation coatings (phosphate, epoxy, polyester, MgO slurry, etc.) uniformly onto both surfaces of running strip before drying and sintering.

Key Specifications

· Raw material: Silicon steel (grain-oriented & non-grain-oriented)

· Strip thickness: 0.15 – 0.65 mm

· Strip width: 650 – 1320 mm

· Line speed: up to 280 m/min

· Coating method: Precision roll coating (2-roll / 4-roll horizontal type), reverse or forward mode

· Control: Closed-loop coat-weight control via roll gap, pressure and speed ratio; optional X-ray / gamma backscatter gauge feedback

· Features: Quick-open coater head for weld-joint passage, standby coater for non-stop changeover, temperature-controlled coating circulation, edge-dam control, compatible with aqueous and slurry-type media

Designed for

Stable coat weight at max line speed, minimal streaking, smooth weld/seam transition, and consistent insulation film quality on thin silicon steel strip.
