The invention discloses a remanufacturing process platform of a blast-furnace tuyere sleeve, which belongs to the field of product remanufacturing. The remanufacturing process platform comprises a heating furnace, wherein the upper end of the heating furnace is open, and a sliding door is installed on the upper end of the heating furnace; a lifting mechanism is arranged below the heating furnace, and a lifting rod is connected to the upper end of the lifting mechanism; the lifting rod passes through the bottom of the heating furnace and enters a hearth of the heating furnace; a support plate which is connected to the upper end of the lifting rod is arranged in the hearth of the heating furnace; arc-shaped countersunk grooves are uniformly formed in the upper surface of the support plate, and balls I are placed in the countersunk grooves of the support plate; and a special tool fixture for the tuyere sleeve is placed on the balls I of the support plate, and the tool fixture can be used for adjusting the axis angle and the rotary angle of the upper blast-furnace tuyere sleeve. The remanufacturing process platform can meet the repair requirements of the damaged positions of the blast-furnace tuyere sleeve at different angles, so that fuel is saved, secondary pollution is avoided, the repair quality is increased, and the manual working environment is improved.
Description
technical field [0001] The invention relates to the field of product remanufacturing, in particular to a remanufacturing process platform for blast furnace tuyere sleeves. Background technique [0002] Blast furnace tuyere sleeve is an important piece of equipment for ironmaking blast furnaces. The main body is made of copper, and the inner cavity of the structural interlayer circulates water. Its working area is located in the blast furnace body, and the working environment is harsh. Coupled with many uncertain factors such as human operation, the blast furnace tuyere cover needs to be replaced if it is slightly damaged. Each blast furnace has a large number of discarded blast furnace tuyere covers every year, causing great losses to iron and steel enterprises. [0003] There are many forms of damage to blast furnace tuyere sleeves, which can be roughly divided into three categories: melting, damage, and wear. Therefore, the shape, location, area, and angle of blast furnace...
