High-intensity industrial cutter for steel rolling

Abstract

The invention discloses a high-intensity industrial cutter for steel rolling, and relates to the technical field of cutters. The high-intensity industrial cutter consists of 15-20 percent of carbonized titanium, 10-40 percent of stainless steel powder, 0.1-5 percent of carbonized tantalum, 0.1-5 percent of carbonized niobium, 10-40 percent of carbonized tungsten, 5-10 percent of carbon powder and 10-20 percent of a hard alloy forming agent. The cutter is high in hardness and good in abrasion resistance and has obviously advantages of heat stability, heat conduction property, corrosion resistance, oxidization resistance, high temperature hardness and high temperature strength; the cutter can continuously and quickly cut steel at high temperature, during the cutting, the friction is small, the cutter is sharp, an incision is tidy and is free of burrs, and for cutting processing production, the cutting speed can be greatly increased, so that the production efficiency is improved; and materials which are difficult to cut can be machined by the cutter, the materials can be accurately machined, a product is high in precision, and as the manufacturing materials are safe and environmentally-friendly, people feel safe and released when cutting foods and medicines with the cutter, and environment friendliness is facilitated.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to a high-strength industrial cutting tool for rolling steel and a preparation process thereof. Background technique [0002] With the continuous improvement of human living standards, the demand for resources is also increasing, and the operating costs of resources and new problems brought about by opening up in increasingly difficult rock formations have brought about the strength of the tool's resistance to fracture and fatigue fracture. Therefore, higher requirements are put forward for wear-resistant materials with high hardness and high strength, new parts, new tools, and tools suitable for extreme conditions. , Traditional cemented carbide is widely used in various cutting tools due to a series of excellent properties such as high strength and hardness, good wear resistance, good red hardness, small thermal expansion coefficient, high elastic modulus and good chemical s...

Problems solved by technology

Compared with other tool materials, the most obvious disadvantages of ceramic tools are insufficient fracture toughness, poor bending strength and thermal shock resistance, and cracks are prone to occur when the cutting temperature changes significantly
