Development Status of Domestic 2.0MM-5.0MM Submerged ARC Welding Wire
Among the many welding materials, 2.0MM-5.0MM Submerged ARC Welding Wire with its unique advantages occupy a large market. Since the 1990s, with the continuous development of 2.0MM-5.0MM Submerged ARC Welding Wire, the automation level of high alloy content and high hardness wear parts manufacturing and repair has also been improved. Development so far, 2.0MM-5.0MM Submerged ARC Welding Wire products covering metallurgy, mining machinery, energy and chemical industry, power, agriculture and other industries equipment repair and manufacturing, and in many areas of wear and tear is quite mature.
At present, China's 2.0MM-5.0MM Submerged ARC Welding Wire production accounted for more than 50% of the total amount of domestic welding materials, about 2.0MM-5.0MM Submerged ARC Welding Wire about 8% of the total area of steel mills Welding repair, cement mill cement mill, grinding plate repair and a large area of multi-layer wear-resistant steel plate welding and so on.
Application of 2.0MM-5.0MM Submerged ARC Welding Wire in Iron and Steel Industry
Modern steel production, processing equipment, harsh working conditions, will be subject to abrasive wear, intermetallic wear and impact wear, resulting in equipment failure or even stop the production of the situation. Iron and steel enterprises are mostly using surfacing method to repair the old roll, in order to improve the service life of the roll, reduce costs. At present, has matured application 2.0MM-5.0MM Submerged ARC Welding Wire automatic submerged arc or arc welding repair and manufacture (except for large-scale cold roll) metallurgical roll, its wear resistance and economic benefits significantly improved. Some enterprises have completed the development and production of a series of products, forming a mature welding process and complete sets of solutions, products in large iron and steel enterprises have been applied and promoted.
Application of 2.0MM-5.0MM Submerged ARC Welding Wire in Cement Industry
2.0MM-5.0MM Submerged ARC Welding Wire in the cement industry production equipment manufacturing and repair has a wide range of applications. Most of the raw materials of the cement production line are made of large vertical grinding, vertical grinding roller and upright, and are subjected to severe low-stress abrasive wear. These equipment surfacing repair, wear-resistant materials are mostly selected high-chromium cast iron arc-shaped arc 2.0MM-5.0MM Submerged ARC Welding Wire. This kind of 2.0MM-5.0MM Submerged ARC Welding Wire carbide in the carbide hard point fine, evenly distributed in the matrix, to ensure that the surfacing layer of excellent abrasive wear resistance. A mechanical manufacturing company using the arc of 2.0MM-5.0MM Submerged ARC Welding Wire manufacturing large vertical grinding mill, surfacing layer hardness above 60HRC, with a good combination of base metal, do not peel off, with good performance. In addition, the cement enterprises hammer crusher and other crushing equipment and fan impeller and other powder equipment wear failure, but also more use 2.0MM-5.0MM Submerged ARC Welding Wire repair.
In addition to the above applications, in the thermal power industry, such as medium-speed mill roll, grinding disc, fan impeller and other surfacing repair; mining mining industry, such as hopper, mineral processing equipment, mining equipment and other surfacing repair; and other industries, , Drilling equipment, construction machinery and agricultural machinery and other surfacing repair, 2.0MM-5.0MM Submerged ARC Welding Wire are widely used, and the application has matured.
2.0MM-5.0MM Submerged ARC Welding Wire in the industry involved in welding are used, and the application is gradually expanding. But the domestic 2.0MM-5.0MM Submerged ARC Welding Wire manufacturers are too scattered, and most of the small size, lack of technical research and development capabilities, 2.0MM-5.0MM submerged arc welding equipment production equipment, product development is low, the quality of wire stability There is no guarantee.
