Installation method of flash smelting furnace

Abstract

The invention discloses an optimized flash smelting furnace mounting method which is characterized by comprising the following steps: (a), arranging a furnace body installation and preparation device of a flash smelting furnace; (b), mounting an auxiliary steel platform and a vertical longitudinal beam of the furnace body; (c) transferring various members into the furnace body; (d) mounting a furnace body bottom beam system, an upright post, a straining beam and a furnace bottom cooling system; (e), mounting a reaction tower and an uptake flue layer by layer; and (f) lifting a steel shell on the upper part of the reaction tower. The optimized flash smelting furnace mounting method disclosed by the invention has the advantages that the manufacturing steps are reasonable in design and simple in operation, the control precision is greatly improved, the construction operation cycle is greatly reduced, the engineering construction cost is reduced.

Description

technical field [0001] The invention relates to a method for installing a smelting furnace, in particular to a method for installing a flash smelting furnace which improves the installation accuracy and shortens the construction period. Background technique [0002] The smelting operation is an indispensable operation in the pyrometallurgical copper smelting process. The dry concentrate is sprayed into the reaction space of the flash furnace, so that the concentrate ions are suspended in the high-temperature oxidizing air flow, and the oxidation reaction of sulfide minerals occurs rapidly by using oxygen-enriched air. , and release a lot of heat to form copper matte. At present, with the rapid development of the national economy, the process of industrialization has been significantly accelerated, especially the proportion of heavy industrial projects in national construction has increased year by year. In many fields such as heavy industrial projects, according to the need...

Problems solved by technology

Generally speaking, the flash smelting furnace equipment has a complex structure, many parts, high installation accuracy requirements, and difficult control during installation, and the construction of the furnace body cannot affect the construction of the plant frame. Therefore, the plant frame has been constructed during the furnace body construction, and the furnace body construction Small space, large amount of installation, difficult construction and high technical requirements

[0004] According to the original design drawings and the overall project progress of the main smelting plant, the installation space of the furnace body is small, there are many parts and components, and the requirements for expansion are high. The overall project schedule is very tight. The known traditional hoisting machinery installation is expensive, long construction period, and affected by the structure of the plant, the operating range is small, the precision control error is large

[0005] Therefore there is above-mentioned inconvenience and problem in known smelting furnace installation method
