Non-oxidation annealing furnace is a system for increasing machinability and construct ability of COIL in order to produce various products of board for automobile, aluminium can, construction and industry electronic through heating, cooling, cracking inside protection atmosphere after paying off COIL of 80ton~150ton for once.

Handuk R-FECO is providing and manufacturing through a smelting furnace from aluminium product process → SLAB homogeneity furnace → COIL plasticity furnace system.
