Abstract

The invention discloses a method for mounting a large-sized flash smelting furnace. The method comprises the following steps: performing comprehensive electronic simulation on the flash smelting furnace, verifying the accuracy of the design size and the preassembling of all parts one by one, mounting according to a sequence of a settling pond and depletion region, a reaction tower, an uptake flue, an electrode and other parts, performing pilot run, and checking and accepting; adopting a three-dimensional logistic technology in a mounting process; taking reversible deformation measures for the whole body during mounting of a bottom beam of a furnace body in the settling pond and depletion region, and welding by using CO2 gas shielded welding. The method is characterized in that the levelness of a flat water jacket is controlled during mounting of the reaction tower, and a method of mounting at first and then positioning and holing is adopted. The method has the characteristics that cross operation can be performed, the working efficiency is improved, construction steps are reduced, the labor cost and the material consumption are reduced, the project quality is improved, the construction cycle is shortened, and general expenses are saved.

Description

technical field [0001] The invention belongs to the technical field of equipment installation, and in particular relates to a method for installing a large-scale flash smelting furnace. Background technique [0002] Flash smelting technology is a metallurgical technology invented by Finland in the early 1950s for processing powdery sulfide ore. It has lightning speed, hence the name flash furnace. Flash smelting technology is one of the most advanced technologies in pyrometallurgy in the world today. It has the advantages of large processing capacity, high degree of automation, low environmental pollution, and low energy consumption. The nickel flash smelting furnace is mainly composed of a reaction tower, a sedimentation tank and a depletion zone, an ascending flue, electrodes, and a cooling water system. The installation of large-scale flash smelting furnaces such as nickel flash smelting furnaces has a large workload, narrow working surface, high technical content, an...
