Stainless steel elbow has many excellent performance, the appearance of sophisticated, long life, can be 100% recycling applications, which can be widely used.
The progress of stainless steel smelting technology, especially after the 1960s, the use of furnace refining and continuous ingot technology to further promote the rapid development of stainless steel to improve the quality of stainless steel and improve the finished product rate, reducing consumption costs.
China from the early 1950s began consumption of stainless steel, was 3t electric arc furnace smelting, no furnace refining equipment and continuous casting, the annual output is only a few hundred tons to several thousand tons, quality, type and cost can not meet the request. Since the 20th century, 80 years, Taiyuan Iron and Steel and Steel Research Institute and other units in China first developed AOD furnace refining process technology. Subsequently, the special steel plant has accounted for 18-40tAOD and 15-60tVOD furnace refining installation, refinement than can also be significant progress. Before 1985, China's stainless steel ingot continued to use backward casting. TISCO 1280 vertical continuous casting machine put into operation in 1985, on the steel plant, Chongqing Special Steel and the five steel mills have slab, billet caster investment spending. 1989, Chengdu Seamless Steel Tube Plant of the degree of continuous casting of stainless steel tube production, completed the stainless steel stainless steel sanitary elbow integrity of the use of molded history. However, due to various reasons, China's annual output of stainless steel constantly around 300,000 t anxious, stainless steel smelting technology, the slow pause, severely limited the development of China's stainless steel. Since 2000, the country to stop the adjustment of the steel industry structure, to encourage the stainless steel industry to carry out a series of policies and measures to make China's steel consumption of stainless steel to complete the development of the Passover, from 1999 to 350,000 t in 2003 to 177.8 million t , An average annual growth rate of about 50%, becoming the world's No. 4 stainless steel steel consumption.
