一、前言流动粒子炉是从充满粉末颗粒的容器底部通入气体,通过底部的布风板,使粉末呈悬浮流动,这种工艺早在1941年美国标准石油公司从重油一中提炼汽油,开发流动接触分解装置时就已经提出,近年来广泛应用在很多领域(见表1)。欧洲早在20年前,就已经把流动粒子炉应用到热处理中,而在日本还刚开始,主要代替铅浴处理及等温淬火。最二、流动粒子炉原理及特征流动粒子炉是在耐热炉体的底部安放一块多孔布风板,气体通过它由底部进入炉体内,由于气体通入,使炉体内充满作为导热体的粒子(如氧化铝)浮动搅拌。通入的气体,根据不同表面处理而异,无氧化加热
I. Introduction Flow particle furnace is filled with powder particles from the bottom of the container into the gas through the bottom of the air plate, the powder was suspended flow, this process as early as 1941, the United States National Standard Oil refinery from a heavy oil to develop Mobile contact decomposition device has been proposed in recent years has been widely used in many areas (see Table 1). Mobile particle furnaces have been used in heat treatment in Europe as early as 20 years ago, and have just begun in Japan, mainly replacing lead bath treatment and isothermal quenching. Second, the principle and characteristics of mobile particle furnace Mobile particle furnace is placed in the bottom of the heat-resistant furnace body of a porous cloth plate, gas through it from the bottom into the furnace, due to gas access, so that the furnace is filled with thermal particles (Such as alumina) with stirring. Access to the gas, according to different surface treatment, non-oxidation heating
