[0002] As we all know: High-performance cemented carbide cutting tools are an important topic for industrial developed countries to devote to research and development. They are the teeth of modern industry and an important basis for measuring a country's industrial level. Materials, as processing materials for hard and superhard materials and difficult-to-machine metal materials, its importance is obvious. my country's high-performance cemented carbide tool materials, especially CNC tool materials, are now basically dependent on imports, which are not only expensive, but also many It has also been restricted, which has a great impact on the process of my country's industrial modernization.

Embodiment 1

[0029] Example 1: In a domestic joint-stock company, the self-made WC-TiC-TaC solid solution has been used to produce a foreign turning tool (CL26417) on the eve of 2005. Due to the increase of the cutting speed of the user, the steel grade of the processed material Changes, the life of the tool cannot meet the requirements. Users have to use imported tools to meet production needs. When the company's scientific research personnel switched to our company's solid solution TRC-33, the life of the tool was greatly improved, and it could completely replace imported tools to meet the production requirements of users, and was well received by users. At present, the product has been mass-produced for more than three years, creating more than 10 million yuan in revenue for the enterprise.

Embodiment 2

[0030] Embodiment 2: Application of TRC-33 in threaded comb cutter base blank:

[0031] High-strength oil pipes are difficult-to-machine materials, and the requirements for the blade matrix material are very high. Due to the user's substantial increase in cutting speed, the comb base material that has been used for many years can no longer meet the user's production requirements, so it is urgent to develop a new material to replace the old basic material. After repeated screening by scientific researchers, the alloy-based material with TRC-33 solid solution was finally selected to meet the needs of users. After adding TRC-33 solid solution, the overall material performance of WC-TiC-TaC-Co alloy is superior, and the product quality is stable. Many times of cutting tests show that the service life of the blade produced by TRC-33 solid solution is longer than that of similar products produced by a famous brand factory purchased by the company, and the independent production of th...

Abstract

The invention relates to tungsten carbide-titanium carbide-tantalum carbide solid solution powder, namely addition of the tungsten carbide-titanium carbide-tantalum carbide solid solution powder TRC-33 during the process of producing cemented carbide materials can make the metallurgical structure of the alloy materials more uniform and the product performance more stable, and obviously improves the strength, the hardness and the toughness of the product. The TRC-33 is a first-rate solid solution, has a forward-looking promotion and application prospect and can further improve the performance of the cemented carbide material WC-TiC-TaC-Co of China.

Description

Technical field: [0001] The invention belongs to the technical field of metal materials, in particular to a tungsten carbide-titanium carbide-tantalum carbide solid solution powder (TRC-33). Background technique: [0002] As we all know: High-performance cemented carbide cutting tools are an important topic for industrial developed countries to devote to research and development. They are the teeth of modern industry and an important basis for measuring a country's industrial level. Materials, as processing materials for hard and superhard materials and difficult-to-machine metal materials, its importance is obvious. my country's high-performance cemented carbide tool materials, especially CNC tool materials, basically rely on imports, which are not only expensive, but also many On the one hand, it has also been restricted, which has a great impact on the process of my country's industrial modernization. Invention content: [0003] The purpose of the present invention is to...
