Embodiment 1
[0009] Embodiment one: see figure 1 , a method for smelting anode slime, which is characterized in that the amount of feed is increased in batches, compressed air is blown at the bottom of the furnace, the charge is stirred to avoid sticky slag sitting on the bottom, 1 / 2 to 1 / 3 of the anode slime is poured out, and then put into Cold material, continue smelting, high-temperature precipitation is shortened from the original 4 hours to 2 hours, slag is released in batches, and then continue feeding and smelting. In each cycle, keep the anode slime of the furnace to account for 1 / 2 to 2 / 3, which can Play a preheating effect on the cold material.

The invention relates to a smelting method, and especially relates to an anode mud smelting method. The anode mud smelting method is characterized in that feeding capacity is increased in batches, compressed air is blown to the bottom of a furnace, so that the furnace burden is stirred, and bottom deposition of bonded slag is avoided; 1 / 2-1 / 3 of the anode mud is poured out, and then, cold burden is added, and smelting is continued; high temperature sedimentation is shortened to be 2 hours from the original 4 hours, slag is discharged in batches, and then, charging and smelting are continued; in each cycle, the anode mud is kept to account for 1 / 2-2 / 3, so that the cold burden can be preheated. In the anode mud smelting method provided by the invention, operation instruction is changed, single cycle is changed into reciprocating circulation, cold burden preheating and hot anode mud cooling interact, energy loss is reduced, anode mud cooling time is shortened, production efficiency is improved, and production cost per ton is reduced.
Description
technical field [0001] The invention relates to a smelting method, in particular to an anode slime smelting method. Background technique [0002] Traditional anode slime smelting mainly adopts feeding, smelting, discharging, slag discharging, and then feeding again. After each link is executed, another process is carried out. Heat loss due to feeding preheating, solution cooling and other links increases production costs. , is not conducive to energy saving and emission reduction. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for smelting anode slime with reasonable design, convenient installation and low cost. [0004] The scheme of the present invention is as follows: [0005] A method for smelting anode slime, which is characterized in that the feeding amount is increased in batches, the bottom of the furnace is blown with compressed air, the charge is stirred to avoid stic...
