The invention provides a device and a method for measuring a material flow orbit of a bell-less type blast furnace. The device comprises a supporting member, a sensing unit and a data analyzing and processing unit. The supporting member comprises more than two straight bars respectively arranged within the range of a common stockline of a furnace throat, and located at high different heights and in more than two cross sections, and any two straight bars form bifacial cross; the sensing unit comprises a plurality of pressure sensors arranged on the straight bars, such that the plurality of pressure sensors are arranged on each straight bar along the length direction; the data analyzing and processing unit is used for receiving the data signal of each pressure sensor and drawing a material flow orbit curve according to the received data signals. The method is implemented by the device. The device and the method provided by the invention can be used for accurately measuring the material flow orbit under a wind loading condition, weakening the man-made influence and eliminating risk factors occurring in a measurement process possibly, thereby having important significance for the stable operation of the blast furnace.
Description
technical field [0001] The invention relates to the measurement of the material flow trajectory of a bellless blast furnace, in particular to a device for measuring the material flow trajectory of a bellless blast furnace and a method for measuring the material flow trajectory of a bellless blast furnace. Background technique [0002] At present, the iron and steel industry is facing huge challenges. Increasing revenue and reducing expenditure is the general direction of the iron and steel industry. The cost of ironmaking is the highest in the entire smelting cost, so there is the greatest room for cost reduction. The normal production of the blast furnace is an important factor affecting the cost of ironmaking, and accurate measurement The material flow trajectory can provide a reference for the normal production of the blast furnace. Usually, the successful start-up of blast furnace is the guarantee for the smooth running of the blast furnace, and the measurement of the ma...
