High strength medium and heavy plates are important materials in construction machinery and major engineering fields.The tempering furnace of medium and heavy plate is an important equipment for producing these products.However,the tem-perature fluctuation of conventional tempering heating technology is large,which can not meet the temperature uniformity re-quirements of low temperature tempering process of these products.Therefore,the State Key Laboratory of Rolling and Auto-mation of Northeastern University has developed a low temperature uniform heating technology and system using circulating hot air.The technology and system are introduced.The practice shows that the low temperature uniform heating technology for tempering furnace of medium and heavy plate can realize the temperature uniformity of±5 ℃ and solve the problem of high tem-perature uniformity of tempering furnace of medium and heavy plate.It provides an important guarantee for the high quality tem-pering production and the development of new process of high strength and wear-resistant steel.
