扩大钢管D51一次冷弯成型范围的理论计算与工艺试验

Theoretical Calculation and Process Test of Expanding the Forming Range of One-time Cold Bending of Tube D51

随着装机容量的不断饱和、国家生态环境治理力度加大,火电市场不断萎缩,各大锅炉制造企业不断转型,进军新能源市场,其中垃圾焚烧炉是东方锅炉主要的新产品之一。垃圾焚烧炉具有压力参数低、空间小、结构紧凑等特点,与传统锅炉产品受热面的管子相比壁厚更薄、相对弯曲半径更小,对弯管质量提出更高的要求。

With the continuous saturation of installed capacity and the strengthening of national ecological environment governance,the shrinking of thermal power market,and the continuous transformation of major boiler manufacturing enterprises to enter the new energy market,among which waste incinerator is one of the main new products of our company.Waste incinerator has the characteristics of low pressure parameters,small space and compact structure.Compared with the tubes on the heating surface of traditional boiler products,the wall thickness is thinner and the relative bending radius is smaller,which puts forward higher requirements for the quality of bends.
