Problems solved by technology

At present, most of the negative pressure control of scrap copper smelting has no practical and effective control strategy. Generally, multiple induced draft fans are installed and the speed of the induced draft fan is increased to ensure that the furnace body does not "spray fire". As a result, on the one hand, the quality of the anode plates produced cannot be guaranteed; on the other hand, it also increases the energy consumption in the production process and increases the production cost

Abstract

The invention discloses a refining furnace. Through the provided refining furnace, the pressure in a combustion furnace and reverberatory furnaces can be controlled accurately. According to the key points of the technical scheme of the refining furnace, the refining furnace comprises the combustion furnace and the multiple reverberatory furnaces arranged on the side face of the combustion furnace; a main channel communicates with the combustion furnace; an auxiliary channel is arranged between the main channel and the upper portion of each reverberatory furnace; an air draft assembly communicates with the main channel; valve assemblies matched in the auxiliary channels are arranged in all the auxiliary channels; a plurality of pressure detection assemblies are arranged in the combustion furnace and the reverberatory furnaces; and a control assembly which controls the valve assemblies and the air draft assembly to operate so as to keep both the pressure in the combustion furnace and the pressure in the reverberatory furnaces in the set range is connected with the valve assemblies and the air draft assembly.

Description

technical field [0001] The invention relates to the field of metallurgical industry, more specifically to a refining furnace. Background technique [0002] Copper is a raw material of great strategic significance in the construction of the national economy, and the regeneration performance of copper is better than other metals, so scrap copper has become an important source of raw materials in the production of copper industry. The waste miscellaneous copper smelting process is to produce qualified anode plates after smelting waste miscellaneous copper raw materials; it mainly includes four processes of melting, oxidation, reduction and casting. In order to improve the quality of the anode plate, the furnace negative pressure must be strictly controlled during the smelting process. [0003] The waste miscellaneous copper smelting process generally adopts a refining furnace, which includes a combustion furnace arranged in the middle and a reverberatory furnace symmetrically ...
