Features of Steel Cord Conveyor Belt
  • High TensileMade by high carbon steel, Steel Cord Conveyor Belt gives a tensile strength above 6,000 kg/cm2.
  • Narrow Pulley DiameterBeing made up of a fine strand, steel cord conveyor belt has excellent flexibility which makes up for its narrower pulley diameter than other general canvas belt's one.
  • High Trough AbilitySteel cord belt is 1 ply so that it features excellence in trough ability
  • Extremely Small ElongationSteel cord belt is a tenth of general canvas belt in elongation so that steel cord belt minimizes the length of take-up
  • Long durabilitySteel cord belt has no extension layer unlike canvas belt, bears the bent fatigue, and adheres closely to rubber, Steel cord belt has excellent resistance to bent fatigue and durability
  • X-ray TestAbnormalities of steel carcass can be detected by X-ray so that a damaged part can be repaired partially.

Item JIS-S JIS-G DIN-W DIN-X DIN-Y
Tensile strength(Mpa) above 18 above 14 above 18 above 25 above 20
Elongation(%) above 450 above 400 above 400 above 450 above 400
Abrasion Resistance(㎟) below 200 above 150 below 90 below 120 below 150
  • Flame RetardationThere are 2 types of standards; MSHA(U.S.A) and FRAS(Australia). FRAS has strict condition.(Test method is in accordance with flame retardation standards).
  • Top CoverIt means the distance between the top of steel cord and the surface of a steel cord conveyor belt. It has something to do with the life span of a steel cord conveyor belt.
  • Bottom CoverIt should be at least 4 mm thick lest it should cause steel cord to protrude.
  • Extremely Small ElongationSteel cord belt is a tenth of general canvas belt in elongation so that steel cord belt minimizes the length of take-up
  • Long durabilitySteel cord belt has no extension layer unlike canvas belt, bears the bent fatigue, and adheres closely to rubber, Steel cord belt has excellent resistance to bent fatigue and durability

Adhesive Rubber

A special rubber which is bonded with a zinc-galvanized steel cord.

  • UseA. To prevent absorption of water which is subject to temperature difference and may lead to weakening of adhesive strength.
    B. For reinforcement of drawing strength of steel cord
  • TypesClassified into NR or NR+SBR according to a given condition or circumstance.
    A. NR: in case of harsh weather condition
    B. NR+SBR: in case of moderate weather condition
  • IngredientsNaphtha Acid Cobalt - for improvement of adhesive strength
    Resorcinol - for improvement of adhesive strength
    Sulfur
    Accelerant (RH)
    Carbon ISF in the ratio of 65%~70%

Steel Cord

A special rubber which is bonded with a zinc-galvanized steel cord.

  • MaterialsCord, made of high carbon steel, is used and High carbon steel cord is used and there are three types of steel cord classified according to steel strength; 7X7(6X7+1WS) type and 7X19(6X19+1WS) type.
  • Galvanized to prevent it from getting rust by long-term use.
  • Cord diameter and pitch are determined by steel strength.
