Lightweight and high-strength titanium-based fine-grained cemented carbide rod material and its preparation process

Abstract

The invention discloses a light-weight high-strength titanium-based fine-grain cemented carbide rod material, which comprises the following raw materials in weight percentage: WC 15%, TiC 51.5%, Si3N4 0.5%, Co powder 8%, Mo powder 10%, Ni powder 15%. Through the above, the light-weight high-strength titanium-based fine-grained hard alloy rod material of the present invention and its preparation process, the reasonable titanium content in the product formula, make the overall density of the hard alloy rod material reach a lower ideal level, and the grain The particle size becomes finer, which makes the overall hardness of the product better; it ensures that the raw powder particles are not agglomerated, the organization is uniform, and it is easy to sinter quickly during the preparation process, avoiding harmful reactions with the binder, and is made of this cemented carbide material The cutting tools have excellent characteristics such as good hardness, high strength, low quality, high wear resistance and long service life, which are very suitable for the processing requirements of carbide drills, milling cutters, alloy steel, titanium alloys, etc.

Description

technical field [0001] The invention belongs to the technical field of cemented carbide materials, and in particular relates to a light-weight and high-strength titanium-based fine-grained cemented carbide rod material for cutting tools and a preparation process thereof. The field of tool making for machining. Background technique [0002] In recent years, with the development of science and technology, the equipment manufacturing industry has developed rapidly, bringing major development opportunities to related supporting industry enterprises. As a manufacturer of special machining tools and special carbide rods for drill bits in the field of equipment manufacturing, it is also facing major development opportunities. However, opportunities are also accompanied by competition, and domestic and foreign related industrial enterprises are also increasing their research on cemented carbide bar material technology, in order to achieve major breakthroughs in industry technology ...

AI Technical Summary

Problems solved by technology

[0003] Although there are hundreds of large, medium and small cemented carbide manufacturing enterprises in China today, there are not many domestic enterprises that focus on the development of lightweight cemented carbide rod materials and technological breakthroughs, and most of the industry enterprises are in the middle and low levels. High-end level, compared with foreign countries, the gap is obvious

Enterprises in foreign industries pay more attention to technological innovation and product performance, especially in Europe, America, Japan and other technologically advanced regions, which have greater technological advantages and market competitive advantages. Representatives include Swedish SANDVIK, German KENNAHERTEL and TITEXPLUS and other well-known manufacturers in the industry, and many Domestic high-end equipment manufacturing knives manufacturers still prefer to import similar foreign products, which cost a lot and are not suitable for widespread use
