FIELD: process engineering.
SUBSTANCE: chain link for heat curtains for rotary annealing furnaces, particularly, for production of clinker by wet process represents a toroidal body with developed surface owing to bulges made thereon. Said bulges are confined by surfaces of different-orientation ellipsoids alternating in stepwise manner along chain link toroidal body lengthwise axis.
EFFECT: ruled out sticking of slime on chain link surface.
