无毛刺热切金属圆锯片及提高热锯片锯切能力的研究两项成果鉴定会,于1990年1月9～10日在北京科技大学召开。会议由冶金部科技司周凤仁高级工程师主持,科技司司长陶信出席了会议并讲了话。 该无毛刺锯片可以有效地去除和降低轧件锯切断面毛刺,使毛刺高度由原来的6～10mm,下降到0.2～2.5mm(国际标准允许毛刺高度3mm),轧件毛刺平均高度1.71mm。使用新研制的锯片,并
Burr-free hot metal circular saw blade and improve the sawing ability of hot saw two identification of results, in 1990 January 9 to 10 held in Beijing University of Science and Technology. The meeting was chaired by Zhou Fenren, senior engineer of the Science and Technology Department of the Ministry of Metallurgical Industry. Tao Xin, director of the Science and Technology Department, attended the meeting and made a speech. The burrless saw blade can effectively remove and reduce the burr on the sawing section of the rolling stock so as to reduce the burr height from 6-10mm to 0.2-2.5mm (the international standard allows the burr height to be 3mm); the average height of the burr on the rolling stock is 1.71mm . Use the newly developed saw blade, and
