Abstract

The invention discloses a blast furnace lining damage condition detection method, which comprises the following steps: installing 3D image equipment outside a blast furnace to photograph and scan furnace throat steel bricks and a furnace lining to obtain depth images of corresponding areas, and analyzing the furnace throat steel bricks and the furnace lining on the depth images by adopting a point cloud data processing technology. The blast furnace lining is scanned and photographed, depth information, namely three-dimensional space coordinate data, of a furnace lining image is obtained, the damage and deformation conditions of the furnace lining are analyzed, and the defects of other measurement methods are overcome. The blast furnace lining damage condition detection method provides technical support for a blast furnace operator to master the damage and deformation conditions of the lining, and effectively guides the blast furnace regulation operation and safety production.

Description

technical field [0001] The invention relates to the field of blast furnace ironmaking in the iron and steel industry, in particular to a method for detecting the damage and deformation of the blast furnace lining. Background technique [0002] The blast furnace is the main equipment of the current ironmaking production. It is a closed high-temperature and high-pressure container, which is equivalent to a "black box". The blast furnace lining is the key equipment to ensure the safe and stable production of the blast furnace. After the blast furnace is put into operation, the situation in the furnace cannot be observed for a long time. Most of the judgments and adjustments of the blast furnace operation are made based on the accumulated experience of the operator. Iron workers are very concerned about the situation in the blast furnace, especially the lining of the blast furnace. Variety. During blast furnace smelting, due to the continuous physical erosion and chemical erosi...
