前言铝材生产一般要经热加工与冷加工二个阶段。在加工中(特别是在热轧与挤压中)存在一个突出的问题,就是工具粘铝的问题,即在工具表面出现粘铝层。它的出现使外摩擦力急增,能量消耗加大;工具表面损
Preface Aluminum production generally go through two stages of hot working and cold working. One of the most prominent problems in machining (especially in hot rolling and extrusion) is the problem of sticking aluminum to the tool, ie the appearance of a sticky layer of aluminum on the surface of the tool. Its appearance makes the external friction increase sharply, the energy consumption increases; the tool surface is damaged
