The invention discloses an intelligent furnace temperature control device and method for a vehicle bottom furnace. Different rotating speeds are set by adopting a circulating fan in the low-temperature condition, and the fan is controlled by grading the furnace temperature or directly giving out the speed percentage of the fan; the heating power of different zones is set through the comparison ofthe temperature difference between the zones, so that the temperature uniformity is realized; in order to improve the temperature uniformity in the furnace and enhance the uniformly heating of the workpiece, five stirring fans are arranged at the top of the furnace, the stirring fans are normally open in the heating process of the electric furnace, and the atmosphere in the furnace is guaranteed to be uniformly stirred. According to the intelligent furnace temperature control device and method, the combustion instability of the vehicle bottom furnace in the low-temperature stage is overcome, the temperature control stability of the vehicle bottom furnace is improved to the greatest extent, the fluctuation of the furnace temperature is reduced, and the heating quality is effectively improved; the operation load of the operator is reduced, and the temperature control flexibility of each zone is ensured.
Description
technical field [0001] The invention relates to the technical field of industrial thermal technology, and more specifically refers to an intelligent furnace temperature control device and method for a car bottom furnace. Background technique [0002] The electric heating car bottom furnace is used for tempering treatment of hot-rolled steel plates. The production process is: high-temperature pen marking before bales enter the furnace → bale loading → heating in the furnace → out of the oven → hoisting the bales to the special cooling support → cooling to normal temperature and then entering the normal storage location. [0003] combine figure 1 The prior art car bottom furnace heating control flow chart, the electric heating car bottom furnace is used for tempering heat treatment of steel plates. The production process is as follows: bundle the package into the trolley and put it into the furnace, then set the heating parameters, turn on the circulating fan, set the heatin...
