轻型钢材是今后扩大产品品种的方向,发展轻型钢材的生产或试制是公司今年技术革新和技术革命重要课题之一。最近,中型厂试制成功一种100×46×4.5毫米轻型槽钢。产品质量符合冶标(УВ)164—63规定,一级品率达96.9%。槽钢对水平轴(X——X轴)的截面系数 W_x=34.8厘米~3,理论重量为8.59公斤/米,比普通10号槽钢减轻1.41公斤/米。这种轻型槽钢是 Light steel is the future direction of expanding product variety, the development of light steel production or trial production of the company this year, technological innovation and technological revolution, one of the important issues. Recently, the mid-sized plant trial success of a 100 × 46 × 4.5 mm light channel. Product quality in line with the standard (УВ) 164-63 provisions, a product rate of 96.9%. The cross section coefficient of channel to horizontal axis (X - X axis) is W_x = 34.8 cm ~ 3, theoretical weight is 8.59 kg / m, which is 1.41 kg / m less than that of ordinary channel 10 steel. This light channel is
