At present, China's continuously released production capacity combined with amazing consumption power is gradually making China a global champion in stainless steel production and consumption. Similarly, the rapid growth of stainless steel consumption in China will inevitably lead to the simultaneous growth of stainless steel welding consumables. The amount of stainless steel welding consumables is also increasing.
I. Development of welding materials: In 1985, the apparent consumption of steel in China was about 50 million tons, and the consumption of welding materials was about 350,000 tons. In 1995, the apparent consumption of steel in China was about 100 million tons, and the consumption of welding materials was about 700,000 tons. In 2000, the apparent consumption of steel in China was about 140 million tons, the consumption of welding materials was about 1.1 million tons, and about 800,000 tons of welded wire rods were used. In 2003, the apparent consumption of steel in China was about 260 million tons, and the consumption of welding materials was about 2 million tons, including: 1.5 million tons of welding treaty. In addition, stainless steel wire used to make stainless steel welding rods and welding wire in 2003 also had more than 20,000 tons. . It can be seen that the number of wires used in welding materials in China is growing rapidly.
Second, the technical level: China's stainless steel welding materials technical level. In recent years, through the efforts of domestic welding technicians, the digestion and absorption of imported technologies and the role of some joint ventures, the level of domestic stainless steel welding consumables has been greatly improved, but there is still a certain gap compared with the advanced level of foreign countries. . First of all, the instability of domestic stainless steel electrode technology. Compared with foreign countries, the quality of domestic stainless steel welding rods has a certain gap in stability. The first reason is that the production is not strict when the manufacturers produce them. Second, the raw materials produced in China are especially unstable due to the unstable quality of the main stainless steel welding wire. At present, domestic stainless steel welding wire is mainly provided by some small and medium enterprises in Jiangsu. Domestic stainless steel welding rods must meet the same quality and stability in foreign countries, and must ensure the quality and stability of raw materials. Stainless steel wire manufacturers must change the backward production process and align with the international advanced level. When purchasing raw materials, manufacturers of stainless steel accessories should pay attention to the selection of raw materials produced by manufacturers with large batches and advanced technology. Secondly, with the development of China's economy, the level of automation is getting higher and higher, and the amount of welding wire is getting larger and larger. At present, Jiangsu Xinghai Special Steel Products Co., Ltd., the company's stainless steel welding wire production introduced advanced foreign microcomputer-controlled hydrogen dewatering water production line, producing high-grade, high-grade, high-performance, diversified, multi-standard series of stainless steel wire, its product application There are a wide range of fields, but there are still few companies that own this equipment in China. Therefore, due to the backward equipment and production process, the internal quality and appearance quality directly cause a large gap with the international.
Third, the demand for stainless steel wire for stainless steel welding: China has become the world's largest consumer of stainless steel, the national consumption of stainless steel in 2003 has reached 4.2 million tons. Some stainless steel products do not need to be welded. Stainless steel that needs to be welded during use is still mainly made of austenitic stainless steels such as 304, 309 and 316.
In 2003, China produced and consumed about 30,000 tons of stainless steel welding materials. Among them: the stainless steel welding treaty is 26,000 to 28,000 tons, the consumption of stainless steel welded steel wire is about 19,000 tons, and the consumption of stainless steel welded steel wire is about 2,000 tons. The total consumption of stainless steel wire is about 21,000 tons. It is estimated that by 2010, China's various stainless steel wires for welding materials will reach 40,000 to 50,000 tons.
Faced with such high demand, stainless steel wire manufacturers are full of confidence in the future, but for this year's export problems, stainless steel wire and steel mills are not optimistic, and some manufacturers have even stopped exporting, all of which are converted to domestic sales.
