Problems solved by technology

However, this control operation is quite different from the operation of controlling the lateral particle size-based segregation of the raw material
Therefore, real-time control of particle size-based segregation in the width direction in response to the lateral air permeability of the raw material layer cannot be achieved with only the drum feeder and the charging chute.
That is, conventionally, it is difficult to control particle size-based segregation in the width direction in real time in response to the lateral air permeability of the raw material layer.

Abstract

The present invention provides an air permeability measuring device and a sintering apparatus including same, wherein the air permeability measuring device comprises: a plurality of rollers spaced apart from each other in the moving direction of a treated material; a plurality of rotation bodies installed on both side ends of one roller and another roller so as to connect between the one roller and the other roller; a flange installed to seal a top surface of the space that is formed by the plurality of rollers and the plurality of rotation bodies; a hollow duct passing through the flange andextending upward; and a flow velocity sensor mounted to the hollow duct. The air permeability measuring device can continuously and precisely measure the air permeability of the treated material, andthe sintering apparatus can continuously and precisely measure the air permeability for each section of a raw material layer.

Description

technical field [0001] The present disclosure relates to air permeability measurement devices and sintering devices. More specifically, the present disclosure relates to air permeability measurement devices capable of continuously and accurately measuring the air permeability of processed materials. Furthermore, the present invention relates to a sintering device capable of uniformly adjusting the air permeability of a raw material layer in the transverse direction while continuously and precisely measuring the segment-based air permeability of the raw material layer. Background technique [0002] Sinter is a blast furnace charging material produced by using fine iron ore, limestone, coke powder and anthracite as raw materials. During blast furnace operation, sintered ore is charged into the blast furnace together with iron ore and coke for the production of molten steel. The sinter production process is a method of sintering fine iron ore and producing sinter having a siz...
