The ways to increase the durability of cutting tools (sintered carbide knives) in the production of steel fiber

One of the ways to increase strength and reliability building structures is use steel – fibre reinforced concrete. Steel concrete has significant advantages over conventional A high degree resistance cracking contributes an in such physical mechanical parameters as compressive, tensile bending strength, water resistance, frost chemical penetration. In concrete, used a reinforcing material, evenly distributed volume process production, fiber cut with carbide knives. The article deals issues increasing wear knives for cutting fibre, suggests durability tools. influence quality tungsten-cobalt hard alloy on analyzed, knife attachment device developed.
