Abstract In order to raise the technical level of equipment and manufacturing capacity of continuous heat treatment line in medium plate mill to produce plate of high quality, high strength and toughness, a normalizing furnace automatic control system and NCC controlled cooling technology was developed independently which is an integration of pulsedigital combustion technique, equipment of fast cooling, electric control system of normalizing furnace and computerized online optimizing control system. Thus a set of integrated technology of medium plate normalization plus controlled cooling was established. This technology fulfills the requirements of plate heat treatment, and the furnace temperature could be controlled within ±10 ℃, with product percent of pass over 96%.
