FIELD: metallurgy.SUBSTANCE: chain for chain curtain of burning device contains connected with each other welded or cast links with oval or round shape. Each link has cross-section limited by closed line, made by internal and external radiuses. External radius is equal to half of overall dimension of the link cross-section, and internal radius is 0.5(B-2b), where B is width, and b is thickness of link body, for oval links or half of link pitch for round links. Interfacing of the external and internal surface of the link is ensured by concave surface at side of external part of the link, and convex surface at side of the link internal part.EFFECT: reduced abrasive wear in places of chain links connection, increased chain break resistance, and keeping of operation mode parameters of burning devices.5 cl, 4 dwg |
