Scientific and technological innovations insist on sustainable development - Zhuzhou Cemented Carbide Group Co., Ltd. takes a new road to industrialization

As one of the 156 key projects constructed during the “First Five-Year Plan” period, Zhuji Group is the largest domestic hard alloy production, research and operation in China, which is based on cemented carbide and integrates tungsten, molybdenum and rhenium smelting and deep processing. And export base. In 2008, Zhuhard Group was awarded the title of “Hunan Province Promoting New Industrialized Red Flag Enterprise” and also won the title of “Zhuzhou City Promoting New Industrialized Advanced Enterprise”. Since 2008, the production and operation of Zhuhard Group has been affected by multiple factors such as snow and ice disasters and the global financial crisis, and there has been a large fluctuation. However, Zhuji Group strengthened internal management, avoided financial risks, maintained profitability throughout the year, and withstood the test of the worldwide financial turmoil.

The level of scientific and technological innovation is further improved
Since the "10th Five-Year Plan", Zhuhard Group has invested nearly 2 billion yuan in technological transformation, the product structure has been continuously optimized, the equipment level has been comprehensively improved, and the research and development capabilities have been significantly enhanced. Metal cutting tool production technology, micro-drill production technology, large-product production technology and tungsten smelting production technology have reached or approached the advanced level of the world, and the production capacity of deep processing and supporting products has been further expanded, and a number of superior fist products have been gradually formed. Such as micro drills, CNC blades, bars, balls, rolls, etc. In 2007, Zhuhard Group's “Development and Industrialization of Key Technologies for Tungsten Industry Chain” was listed as a major provincial science and technology project, and the project is currently under implementation. In 2008, Zhuhard Group applied for 34 patents and authorized 13 patents, of which 23 were applied for by the headquarters and 10 were authorized. The “Diamond Brand” trademark was recognized as a well-known trademark in China by the State Administration for Industry and Commerce in 1999. The “Diamond Brand” cemented carbide was awarded “China Famous Brand” product by the State Bureau of Technical Supervision in 2007, “Diamond Brand” tungsten powder, “ The diamond brand "tungsten carbide powder" was recognized as "Hunan Famous Brand" by Hunan Quality and Technical Supervision Bureau in 2007. These advantages added many highlights to the impact of the financial hardship against the financial crisis in 2008. Zhuhard Group's CNC blade increased by 29%, micro-drillage output by 24%, bar production by 23%, and bit alloy output by 14%. In 2008, Zhuji Group invested a total of 69.764 million yuan in research and development, accounting for 3% of the main business income, and the new product contribution rate was 25%.

Further optimization of environmental protection capabilities
Through technological transformation, Zhuhard Group relocated tungsten smelting, shut down cobalt smelting, properly disposed of hazardous solid waste and waste emulsion, cutting fluid, invested millions of yuan to increase the comprehensive treatment of wastewater, and wet The smelting products have been restricted to production and sold to minimize the impact of pollution on the environment. Through project construction and special investment, the compliance rate of major pollutants of Zhuhard Group reached 97.78%; the total reduction rate of major pollutants in 2008 was SO2: 23.47%; the emission intensity of major pollutants of industrial output value was SO2: 0.681 kg.

The effect of energy saving and consumption reduction is further revealed
Guided by “energy saving, scientific development”, Zhuhard Group has basically achieved energy conservation goals by strengthening energy conservation awareness, strengthening energy management, refining assessment indicators, and promoting energy-saving technologies. In 2006, Zhuhard Group introduced a natural gas hydrogen production system to improve the energy structure. In 2007, the reorganization of the rehabilitation bathhouse was strengthened to control the energy consumption of non-production, reducing steam consumption; strengthening the maintenance of the power pipeline network and reducing tube loss. Zhuhard Group fully considers energy conservation and environmental protection factors in technological transformation and equipment investment. The coal-fired boiler energy-saving technical transformation project started in 2008, with a total investment of 22.4 million yuan, construction of one 10t/h and one 6t/h natural gas boiler The house and its supporting facilities replace the original one 35t/h and two 20t/h coal-fired boilers, use the waste heat of the hydrogen production unit for the bathhouse, and transform the heating pipe network system. After the project is implemented, it can save 13769.3 tons/year of standard coal, annual emission reduction of SO2220.19 tons/year, and smoke dust of 116.82 tons/year. The pollutant reduction rate can reach more than 99%, which is conducive to regional environmental protection and total quantity control. In 2008, the comprehensive energy consumption per 10,000 yuan of output value was 0.12 tons per 10,000 yuan, a decrease of 25.9% compared with the same period of last year. The consumption of raw coal decreased by 8.3%, and the consumption of hard alloys decreased by 8.28%.

The level of industrial informatization is further improved
According to the requirements of the central government's "adhere to the use of information technology to promote industrialization, industrialization to promote informationization, and take a new road to industrialization," the company will take information construction as a major event of the company. In 2002, Zhuhard Group invested nearly 20 million yuan to build an internal optical fiber network, purchased two small computers, established a company website and an e-commerce website, and realized paperless office using office automation software, and built a marketing system suitable for the group itself. Management system. And pay attention to the informationization investment in the project construction process, the production management system has been established in the construction process of key technical transformation projects such as mixing materials, roll deepening, cobalt powder, ball teeth and molds. In 2008, the investment in information technology of Zhuhard Group reached more than 1.4 million yuan, accounting for 0.6% of the industrial added value. Grades can only represent the past. Zhuhard Group will seize the favorable development environment of the country's macro-economy, increase the intensity of technological transformation, enlarge and strengthen the superior products, take technological innovation as a means, take the road of sustainable development, and make the company a strong cemented carbide in the world. enterprise.

An ideal material in high temperature applications, which has high operating temperature up to 550°C and above, with excellent corrosion resistance. They can become partially demagnetized if they come in contact with other ferrous materials, special care is required during handling and storing. 

Usually cast and grinded during production, they are available in various grades depending on its application. Others such as sintered Alnico have lower magnetic properties but offer higher mechanical characteristics

Casting Alnico

With low temperature coefficient, higg temperature resistant, resistant to moisture, not easy oxidation and working stability well.
