    Application

    Armored Face Conveyors (AFC), Beam Stage Loaders (BSL), road header machines, coal plows, etc.

    1

    As the No. 1 coal production country, China has seen demand of huge quantity round link mining chains, and thus been encouraging China round steel link chain manufacturing capacity in terms of quantity and quality. SCIC’s chain factory with its 30 years round steel link chains production history has been fully involved into China coal industry supply; our Round Link Chain have been so far well accepted and used by all the main coal & mining companies through China.

    Our round steel link chain quality is ensured through each step of chain production, from sound alloy steel bars to precise link fabrication by robot, from computerized flash butt welding to well designed quenching & tempering heat-treatment (resulting in desired strength and surface hardness), from proof test to mechanical tests on verifying the surface & inner quality.

    Chain Parameter

    SCIC Round Link Chain is made according to China GB/T-12718 standard and factory Technical Requirements, as well as to DIN 22252 or GOST 25996 standards and clients specs

    SCIC Round Link Chain is used for Armored Face Conveyors (AFC), Beam Stage Loaders (BSL), road header machines, coal plows and other equipment that requires this type of chain.

    Anti-corrosive coatings (e.g., hot dipped galvanization) result in decreased chain mechanical properties, therefore the application of any anti-corrosive coatings shall subject to order agreement between buyer and SCIC.
