Problems solved by technology

[0002] The heating up of traditional lead smelting furnace mainly adopts feeding, smelting, molten liquid, slag discharging, and then feeding. After each link is executed, another process is carried out. Due to the heat loss caused by feeding preheating, solution cooling and other links, the increase Increased production costs, not conducive to energy saving and emission reduction

Embodiment 1

[0009] Embodiment one: see figure 1 , a method for raising the temperature of a lead smelting furnace body, 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, and the slag is prevented from sitting on the bottom, and 1 / 2 to 1 / 3 of the melt is poured out. Then put in the cold material and continue smelting. The high-temperature precipitation is shortened from the original 4 hours to 2 hours. The slag is discharged in batches, and then the smelting is continued. In each cycle, the melt in the furnace body is kept to account for 1 / 2 to 2 / 3 , can play a preheating effect on the cold material.

Abstract

The invention relates to a smelting method, in particular to a temperature rise method for lead smelting furnace body. The temperature rise method is characterized in that the feeding capacity is increased in batches, compressed air is blown from the furnace bottom, furnace burdens are mixed, so that bonded slag is prevented from bottom sitting, 1 / 2-1 / 3 of a smelting solution are poured out, then cold burdens are fed, smelting is continued, high-temperature precipitation is shortened to be 2 hours from original 4 hours, the slag is fed in batches, then feeding is continued to smelt, in each cycle, the smelting solution of the furnace body is kept to account for 1 / 2-1 / 3, and the preheating effect performed on the cold burdens can be achieved. According to the temperature rise method for the lead smelting furnace body, operation procedures are changed, a single cycle is changed to be the reciprocating cycle, cold burden preheating and hot smelting solution cooling interact mutually, energy losses are reduced, besides, smelting solution cooling time is reduced, the yield efficiency is improved, and production cost per ton is reduced.

Description

technical field [0001] The invention relates to a smelting method, in particular to a method for raising the temperature of a lead smelting furnace body. Background technique [0002] The heating up of traditional lead smelting furnace body mainly adopts feeding, smelting, molten liquid discharge, slag discharging, and then feeding. After each link is executed, another process is carried out. Due to the heat loss caused by feeding preheating, solution cooling and other links, the increase Increased production costs, not conducive to energy saving and emission reduction. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a method for raising the temperature of a lead smelting furnace body with reasonable design, convenient installation and low cost. [0004] The scheme of the present invention is as follows: [0005] A method for raising the temperature of a lead smelting furnace body, which ...
