No. Of patent: ZL69222909.1
(1). Special furnace model design, composite type chamber wall, high efficient nozzle & heat exchanger and direct firing mode make thermal efficiency improved nearly one time than traditional steel wire heating treatment, energy consumption index has reached international advanced level.

(2). Accurate temperature controlling, furnace inner atmosphere controlling and high DV value operating make oxidation loss rate reduce 40бы.

(3). Special module design of oil feeding and metering pump control mode(No. Of patent, ZL96222909.1), make the error of furnace temperature control extremely minimal.

(4). Novel temperature air-fuel ratio(acoefficient)setting, controlling and displaying makes computer control system operated easily.

(5). No black smoke and pollution to environment.

(6). Special furnace structure makes working life longer, minor repair cycle is 3 years and 10 years of heavy repair cycle.
