There are many factors that affect the reverberatory furnace lead smelting. Only targeted improvements can improve the smelting efficiency. In view of the problem of the melting speed of the charge; the coal quality can be strictly controlled: the lump coal contains fixed carbon>60%, ash<10%, coal surface<5%, calorific="" value="">7000 kcal, and the flame generated by combustion is longer, which is conducive to the distribution of temperature in the furnace; the reverberatory furnace should be operated under a slight negative pressure, mainly to ensure the flow rate of high-temperature flue gas in the furnace, so as to facilitate heat conduction in the furnace. If the suction force is too large, the flame or high-temperature flue gas and fine materials will be drawn away, which will not only affect the melting of the material, but also block the dust collection system, and in severe cases, the bag will be burned. The adjustment method is to properly open the lower plug plate of the surface cooler or the lower electric plug plate of the bag dust collector. If the suction force is too small, most of the high-temperature flue gas and flame rush to the top of the fire chamber, and part of it will be ejected from the coal feeding port, which will not only fail to reach the melting temperature of the material, but also shorten the service life of the furnace fire chamber and increase the labor intensity of the operator. The treatment method is to find the cause in time. If the furnace tail is seriously blocked, clean the furnace; if the dust collection system flue is blocked, clean the flue.

In addition to technology, the responsibility of the fire burner should be strengthened and the operation level should be improved. The combustion process of the artificial coal-adding combustion chamber is cyclical. In order to improve the economy, the coal-adding cycle should be reasonably shortened during the burning. The amount of coal added to the furnace should be small and the number of times should be large. It is required to be spread evenly and the local temperature should not be too high or too low. Rapidly increase the temperature and maintain a stable high temperature, strengthen the stirring of the melted charge in the furnace to ensure that the charge can melt and react quickly at high temperature.

Starting from the above perspectives can well deal with the factors affecting the lead smelting of the reverberatory furnace, thereby improving efficiency.
