The only tungsten deep-processing enterprise in Jiangxi - Nanchang Cemented Carbide Co., Ltd., according to the "high starting point, high standards, and super-conventional" development ideas, intensified technological transformation and technology import efforts, accumulated investment of more than 200 million yuan in 5 years, completed There are three key construction projects for ultra-fine tungsten carbide, fine-grained hard alloys, and cemented carbide drilling tool production lines. Focused on product structure adjustments and market structure adjustments, significantly increased the production of high-quality, high-grade, high-value-added products and sales on the domestic market. The growth rate of comprehensive sales of deep-processing products reached 14.2%, and new sales revenue was 325 million yuan. With an annual production capacity of 5,000 tons of ammonium paratungstate, 7,000 tons of tungsten oxide, 3,000 tons of tungsten powder, tungsten carbide powder, 1,000 tons of carbide, and 6 million carbide machining tools, it has entered the top five in the national hard alloy industry.
In recent years, the company has continuously increased R&D investment, accelerated the pace of technological progress and technological transformation, and established an internationally advanced ultra-fine and nano-grade tungsten carbide powder, ultrafine (nanometer) crystal and high-performance carbide alloy materials and precision tool R&D platform. , Establishing hole processing tools, high-performance precision indexable cutting insert cutting laboratory, improving equipment level, perfecting research and development methods, striving to build a national-level technical center; advancing and implementing a series of technical reform projects, and replacing traditional spray-drying mixture preparation processes Mixing material preparation process, vigorously promote the modern hard alloy production process technology, continuously improve the overall process quality control level; expand the deep processing business of hard alloy, increase the added value of products; expand the production capacity of hole processing tools, establish the production line of the ring gear drilling tool, The industrial chain extends to the field of hard alloy matching tools.
