The invention relates to a pressure correction electronic scale for a furnace top burdening system of a blast furnace. A signal output end of a weighing sensor is connected with a weight transmitter; a signal output end of the weight transmitter is connected with a pressure correction controller; an air pressure sensor is arranged in a charging bucket; a signal output end of the air pressure sensor is connected with the pressure correction controller by a pressure transmitter; and signal input ends of a pressurizing valve and a relief valve are respectively connected with the pressure correction controller. The invention provides the pressure correction electronic scale for the furnace top burdening system of the blast furnace, which solves the problem that weighing is changed greatly in the charging bucket under the action of pressurizing and relief, has a simple structure and high accuracy and reliability, and is convenient to operate.
Description
technical field [0001] The invention relates to a weighing device of a batching system of a blast furnace, in particular to an electronic scale for pressure correction of a batching system of a blast furnace top. Background technique [0002] my country's iron and steel metallurgical enterprises, especially large iron and steel plants, have adopted the conversion of eliminating small blast furnaces and building new large blast furnaces. The scale effect can achieve energy saving and emission reduction, improve production efficiency, and improve product quality. At present, the newly-built blast furnace is generally more than 2,000 cubic meters. This type of blast furnace must be equipped with a blast furnace pressure correction furnace top electronic scale to add the charge to achieve the purpose of uniform distribution. [0003] In order to correctly grasp the weight of the furnace charge and realize uniform distribution, it is necessary to accurately measure the weight of ...
