一、概述 近年来非晶薄带作为一种新型的金属材料日益受到重视,但目前制取的非晶薄带中尚存在着不少外形质量问题,如钢带的纵向、横向公差较大,材料的收得率不稳定,表面质量欠佳等.这些因素都阻碍着非晶薄带的推广应用。 用单辊外圆牵引法制造非晶薄带,有许多工艺参数影响薄带的质量,其中坩埚喷嘴与辊表面的间距(以下筒称“间距”)是最重 I. Overview In recent years, amorphous ribbon as a new type of metal materials have received increasing attention, but there are still a lot of appearance quality problems in the current amorphous ribbons, such as the longitudinal and transverse tolerances of the strip are large, Unstable material yield, poor surface quality, etc. These factors hinder the popularization and application of amorphous ribbons. There are many process parameters that affect the quality of the strip, with the distance between the crucible nozzle and the surface of the roll (hereinafter referred to as “pitch”) being the heaviest
