Guide: in tunnel excavation, the shield machine is invincible, relying on the sharp shield knife. The shield cutter is therefore known as the teeth of the shield machine. Zhuzhou Cemented Carbide Group Co., Ltd. has become an important supplier of shield machine tools in China. Wu guogen, general manager of Zhuzhou hardware, was interviewed today. The concrete pressure testing machine is specialized in testing the compressive strength of concrete

tunneling, shield machines are invincible, relying on the extremely sharp shield knife. Therefore, the shield cutter is known as the "tooth" of the shield machine at chinaplas2019 International Rubber and plastic exhibition. Zhuzhou Cemented Carbide Group Co., Ltd. has become an important supplier of shield machine tools in China

In an interview today, Wu guogen, general manager of Zhuzhou hardware, revealed that recently, the right line between the provincial government and Youyi Road of Changsha Metro Line 1 was successfully connected, and the cutters used in shield tunneling were provided by Zhuzhou hardware. According to the relevant person in charge of China Railway 12th Bureau, who undertook the construction task, the whole area was 1.2 kilometers away, and the cutting tools were not replaced, and the excavation was successful at one time

shield machine is recognized as a major key equipment to measure the equipment manufacturing level of a country; Among them, the shield cutter is the "pearl on the crown", and its performance determines the quality, efficiency and cost of shield construction. However, previously, shield cutters were almost monopolized by foreign brands

in 2010, Zhuzhou hard's "Research on industrialization technology of key raw materials of high-performance cemented carbide and shield cutting tools" was included in the national science and technology support plan project. In 2011, Zhuzhou hard Machinery Co., Ltd. established a drilling tool company, which specializes in the research, development, production and operation of shield cutting tools. At present, all kinds of shield cutters such as hobs and cemented carbide cutters, which are independently developed, designed and manufactured, can be used in all well-known shield machines at home and abroad to meet the tunneling operation of shield machines under various geological conditions

no diamond, no porcelain work. The reputation of Zhuzhou hard shield cutting tool is based on the strength shown in overcoming difficulties in construction. In August, 2012, during the construction of a bid section of Shenzhen Metro, the geological conditions were extremely complex, and the tool performance provided by Zhuzhou hardware was much better than that provided by other suppliers, winning high praise from the construction unit. Finally, Zhuzhou hardware and Steel Co., Ltd. provided all shield cutting tools for the construction party in the way of overall contracting

it is understood that in addition to Changsha, Zhuzhou hard shield cutters have been used in the construction of subway and railway tunnels in Beijing, Shenzhen, Guangzhou, Shenyang, Nanjing and Chengdu, as well as the construction of national key projects such as the South-to-North Water Diversion Project and the Yangtze River Crossing Project of the west to East gas transmission project, as well as the construction of municipal administration. In the first quarter of this year, the production of shield cutters of the company increased by 1064% over the previous year
