INVESTMENT CAST, STAINLESS STEEL CHAIN LINK AND CASTING PROCESS THEREFOR

摘要

An investment cast, stainless steel chain link is provided for chains used in water and wastewater treatment. The chain link comprises a pair of spaced apart, elongated sidebars having forward ends and rearward ends. The forward ends a re spread apart and are provided with outwardly and laterally extending bosses having transverse boss pin bores coaxially aligned with each other. The rearward en ds are interconnected by a cylindrical barrel having a barrel pin bore extending through each of the sidebars. The sidebars are formed with outwardly and laterally projecting reinforcing ribs extending between the bosses and the barrel pin bore along a substantial length of the sidebars. A freely rotatable chain pin is inserted through aligned boss and barrel pin bores from either end thereof for interconnecting first and second pairs of sidebars. An arrangement is provid ed for preventing the lateral dislodgement of the chain pin from the sidebars.
