Abstract: Sodium tetraborate based carrier coatings for wire drawing are prepared by dispersing a water insoluble fatty acid metal salt in a sodium tetraborate coating bath. The carrier coatings on rod are made resistant to atmosphere moisture by heating at an elevated temperature.Carrier coatings on wire rod provide a vehicle to pick up the wire drawing lubricant in the soap box and carry the lubricant into the die. Since the coated wire rod is often stored for long periods between coating and drawing it is susceptible to corrosion from atmospheric moisture.

Abstract: Sodium tetraborate based carrier coatings for wire drawing are prepared by dispersing a water insoluble fatty acid metal salt in a sodium tetraborate coating bath. The carrier coatings on rod are made resistant to atmospheric moisture by heating at an elevated temperature.Carrier coatings on wire rod provide a vehicle to pick up the wire drawing lubricant in the soap box and carry the lubricant into the die. Since the coated wire rod is often stored for long periods between coating and drawing it is susceptible to corrosion from atmospheric moisture.BACKGROUND OF THE INVENTIONThe two principal carrier coatings for drawing rod are based on borax or lime. Lime carrier coatings have two main disadvantages. First, it is difficult to apply a lime coating since the lime floats in the water. Secondly, the lime coating flakes off lime particles in the work area causing disagreeable breathing conditions and dirty work areas.
