一、前言由于高频电焊钢管生产具有投资少、上马快、能耗低、效益高和销路广等一系列优点,因此,近年来国内外生产高频电焊管的厂家日趋增多。但是,风动式飞锯所切割的产品定尺精度太低,从而造成了成材率下降和销售价格的低廉,最终导致经济效益上的损失和市场上竞争能力的先天不足。 I. Preface As a result of a series of advantages of high frequency welded steel pipe production, such as less investment, quick start up, low energy consumption, high efficiency and wide sales, etc., the manufacturers of high frequency welded pipe at home and abroad have been increasing in recent years. However, the precision of the products cut by the wind-driven flying saw is too low, resulting in a decrease in the finished product rate and a low sales price, which ultimately leads to the loss of economic benefits and inherent deficiencies in the market competitiveness.
