High infrared paint-film quick solidification technology

摘要

Early in 70s of this century,far infrared heating technology was first advanced by japan.For saving energy,while using ht etechnology to design dry-furnaces in series,"MATCH ABSORBING" was esp stressed,but for even temperature,the "MATCH ABSORBING" had to be given up,far infrared furnaces with advancing technology index had not been produced incoluding Japan.So hot air cycle dry furnaces were sued in process of paint-film solidification in most of countries in the world until 1990.
