一、前言轧制铝带材卷筒的退火方法是将卷筒展开,同时通过加热炉进行连续退火,这种方法实际上已经使用很久了.在高温气体介质中铝带材短时间通过时,必须给它一定的热量,铝带材本身的升温速度通常为每秒几度.与以前的间歇式退火法的升温速度(每分钟几度)相比大约大二个数量级.当采用连续式退火时,在材料加热之后,紧接着进行快速冷却.这样,通过快速退火可以得到与间歇式退火材料不同的某些特性.因此作为快速退火纯铝板的典型性能,对有关软化再结晶特性及轧制硬化特性的试验结果加以介绍.
I. INTRODUCTION The annealing of rolled aluminum strip rolls is carried out by unwinding the rolls while continuously annealing them through a heating furnace which has actually been used for a long time.When the aluminum strip is passed through in a hot gas medium for a short time, It must be given a certain amount of heat, the aluminum strip itself is usually heated at a rate of several degrees per second, about two orders of magnitude greater than the rate of temperature rise (several degrees per minute) with the conventional batch annealing method, When the material is heated, followed by rapid cooling, so that by rapid annealing can be obtained with the intermittent annealing of certain properties of the material.Therefore, as a typical performance of annealed pure aluminum plate, the softening recrystallization properties and rolling The result of the hardening test is described.
