Problems solved by technology
[0002] In order to solve the segregation phenomenon of the material entering the blast furnace charging system, the material will be redistributed before the material enters the blast furnace charging system to ensure the uniformity of the material entering the charging system tank and avoid the impact of material segregation on the blast furnace material distribution. Causes uneven particle size distribution of materials in the blast furnace and affects the distribution of rising gas in the blast furnace
[0003] The blast furnace tube insert is installed on the support beam in the blast furnace receiving tank, which is composed of an insert support beam, a cantilever device, etc. The insert support beam is equipped with an inner lining, a top lining, an inner lining and The top liner is directly poured with wear-resistant steel. In actual operation, there are the following defects: 1) The charge moves from top to bottom, and the charge and inserts rub and collide with each other. The carbon steel frame is worn out, the replacement is difficult and the cost is high; 2) The improved front liner is assembled as a split casting. In the weighing tank on the top of the blast furnace, due to the heavy liner, it is difficult to install with bolts, and the labor intensity of the workers Large, low production efficiency

Abstract
The invention relates to a novel siamesed blast furnace material pipe insert cambered lining board which is composed of an upper inner camber board, a bottom board, an upper outer camber board, a lower outer camber board, a lower inner camber board and the like, wherein the left side of the upper part of the bottom board is provided with the upper inner camber board, the right side of the upper part of the bottom board is provided with the upper outer camber board, and the upper inner camber board is connected with the upper outer camber board through a connection board; the external surfaces of the upper inner camber board, connection board and upper outer camber board are respectively provided with an overlay welding layer; the left side of the lower part of the bottom board is provided with a lower inner camber board, and the right side of the lower part of the bottom board is provided with the lower outer camber board; an upper oblique board is arranged above the left side of the lower inner camber board, and a lower oblique board is arranged below the left side of the lower inner camber board; and the overlay welding layer is made of a high-temperature-resistant wear-resistant alloy with the hardness of HRC 58-62. The lining board is reasonable in structure, and protects the outside of the support beam; the lining board does not use bolt connection, and is convenient to install after block lifting; the lining board has the advantages of high wear resistance and no deformation after long-time use, and the service life is prolonged by 3-4 times; and the lining board saves the production cost, and has favorable economic and social benefits for popularization.
Description
technical field [0001] The invention belongs to the field of metallurgical equipment, and in particular relates to a new one-piece curved lining plate for inserting part of a material pipe of a blast furnace, which is suitable for a material distributing system of a blast furnace receiving tank in the metallurgical industry. Background technique [0002] In order to solve the segregation phenomenon of the material entering the blast furnace charging system, the material will be redistributed before the material enters the blast furnace charging system to ensure the uniformity of the material entering the charging system tank and avoid the impact of material segregation on the blast furnace material distribution. The particle size distribution of the material in the blast furnace is uneven, which affects the distribution of the rising gas of the blast furnace. [0003] The blast furnace tube insert is installed on the support beam in the blast furnace receiving tank, which ...
