摘要： A compact steel cord is provided. The cord includes a core-filament I steel wire with a diameter of d0, and four middle-layer M steel wires with a diameter of d1 and eight outer-layer O steel wires with a diameter of d2 that are twisted around the core-filament I steel wire in the same lay direction and the same lay length. Gaps L are reserved between the outer-layer O steel wires, an average width of the gaps L is not smaller than 0.02 mm, and the total size of the gaps L is larger than d0 and smaller than d1. The steel cord of a stable structure can be obtained by controlling the proportion of the sizes of all layers of monofilaments, the rubber coating performance of a tire cord can also be improved, the corrosion resistance, fatigue resistance, impact resistance and adhesion retention of a tire are improved.

摘要： A steel filament for twisting into a steel cord for the reinforcement of rubber articles, which contains a steel substrate that is coated with a coating comprising brass. The coating is different in that the amount of iron at the surface is distinctively higher than that prior steel filaments. The coating has an average iron content of 4 or more atomic percent compared to the total of iron, zinc and copper atoms in the layer extending from the surface to a depth of 3 nanometer below the surface. The steel filaments show an improved adhesion retention under hot and humid conditions and in organic cobalt compound containing rubbers as well as rubbers that are substantially free of cobalt. The lifetime of the rubber article is extended.

摘要： A wire drawing apparatus (10) is used in a final drawing process to ensure adequate initial performance of adhesion between brass-plated steel wire and rubber without a drop in productivity. At least one of the die (14z) disposed in the most downstream position, the die (14y) disposed in the second most downstream position, and the die (14x) disposed in the third most downstream position is a drawing die having a friction coefficient μ of 0.12 to 0.41 with the brass-plated steel wire. The other dies (14) are drawing dies each having a friction coefficient μ of 0.1 or below. By using these drawing dies, brass-plated steel wire (13) is drawn, and a noncrystalline portion of high lattice defect density is formed on the surface of the crystalline portion of the brass-plating layer of the brass-plated steel wire (13).
