Conveying chain for stainless steel plate production line Technical Field The utility model relates to the field of chains, in particular to the technical field of conveying chains for stainless steel plate production lines. Background The production capacity of the conventional thick plate in the metallurgical industry is seriously excessive, and each large steel factory is subjected to iterative product upgrading, so that the conventional thick plate production line which is produced originally is successively transformed into a nickel-containing titanium alloy thick plate production line, namely a stainless steel plate production line. Because of the special nature of the stainless steel product, the surface quality and the requirement on the cleanliness of the product are high, and the stainless steel product cannot be knocked or scratched and cannot have any oil stain and other requirements. The chain used by the prior thick plate can not meet the quality requirement of the product after conveying and upgrading, so that the conveying chain suitable for the stainless steel plate production line is developed and produced to be matched with the iterative upgrading and reconstruction of the prior steel mill, and the conveying chain solves the problem of product conveying in the metallurgical industry.
