INNOVATIVE PROJECTS - I

REPLACEMENT OF WATER COOLED HEARTH ROLL BY NON WATER COOLED CERAMIC ROLL – 2 Nos

Hearth Roll are used in Non Ox Furnace to support the sheet. To cool the temperature of the Hearth Roll, water is passed through it.

Water Flow through the Hearth Roll is 36m3/Hr. Temperature Gain of water across the Hearth Roll is 6 Deg C.

Vendor Sandvik Asia suggested APM Technique based Non water cooled ceramic roll for this application.
