Abstract
The utility model provides a steel cord for semisteel meridian, the carbon content of the single wire of the steel cord is 0.91-0.93%, the chromium content is 0.15% -0.30%, the lay length of the single wire is 13-15mm, and the diameter of the single wire is 0.24-0.25 mm. Steel cord, can reduce curtain cloth thickness when satisfying operation requirement, alleviate the interior steel wire weight of curtain cloth, reduce the interior rubber use amount of curtain cloth, reduce curtain cloth total weight. Steel cord can improve the fatigue resistance ability of tire, increase and renovate the number of times, realize the tire lightweight, reduce rolling resistance, improve tire comprehensive properties to can reduce producer and user use cost, accord with the new requirement of the energy-concerving and environment-protective of tire.
Description
Technical Field
The utility model belongs to the technical field of the steel cord is made, concretely relates to steel cord for semisteel meridian.
Background
Steel cords are widely used in rubber products such as automobile tires, conveyor belts, high-pressure hoses, etc., and are required to have good strength, toughness, fatigue resistance, rubber permeability, adhesion, etc., as reinforcing materials for rubber products. The steel cord is mainly used as a reinforcing material of automobile tires, and can be made into steel cord fabric for use or directly used for a tire body. The steel cord used for semi-steel meridian generally has structures of n x 1, m + n, etc., and they generally consist of two or more steel wires, however, the more steel cords and rubber are needed to achieve a certain strength by twisting the two or more steel wires together, and the production cost is large.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the big problem of high strength semisteel meridian steel cord and rubber quantity, developed a semisteel meridian steel cord, steel cord can improve the fatigue resistance ability of tire, increase and renovate the number of times, realize the tire lightweight, reduce rolling resistance, improve tire comprehensive properties to can reduce producer and user use cost, accord with the new requirement of tire energy-concerving and environment-protective.
The utility model adopts the technical scheme that: a steel cord for semi-steel meridian, the linear density of the steel cord is 3.0-4.0g/m, the carbon content of the monofilament is 0.91-0.93%, and the chromium content is 0.15% -0.30%.
The further monofilament lay length is 13-15 mm.
The further filaments have a diameter of 0.24-0.25 mm.
Further steel cord breaking force 330-.
The steel cord monofilament of the utility model contains a certain amount of carbon element and chromium element, and the quenching strength can be further improved. Steel cord be arranged in radial tire matrix or belted layer, can improve the fatigue resistance ability of tire by a wide margin, can reduce the use of steel cord and sizing material, realize the tire lightweight, reduce rolling resistance, improve tire comprehensive properties to can reduce use cost, accord with the new requirement of tire energy-concerving and environment-protective.
