Many lead smelting furnace equipment workload can not be the same as before, and can ensure the continuous supply of lead smelting raw materials. At present, many lead smelting furnaces have implemented crude lead refining technology. It is speculated that many people, like editors, are curious about how lead smelters refine crude lead.
Lead smelting reverberatory furnace consists of furnace bottom, furnace bottom, furnace wall, furnace top, charging port, product outlet and flue. Auxiliary equipment includes feeding device, blowing device, exhaust device and waste heat utilization device. If a heat exchanger is not used, the temperature of the combustion air is normal. The ceramic heat exchanger has high heat exchange temperature, and the temperature of the heated combustion air can reach 300-800 degrees, which can not only achieve the purpose of energy saving, but also improve the environmental benefits. Flue is located at the end of the furnace, there are straight flue and inclined flue. The latter has less resistance to air flow, where dust will precipitate, thus reducing the dust rate. The side walls of the flue are made of firebricks and the top is also a ceiling. In order to reduce the failure of flue, the flue is usually built wide and short. In order to regulate the air flow, a gate is installed in the flue.
When loading trucks, please check the condition of materials to avoid mixing flammable and explosive materials. Then, make sure that the generator room is clean and free from combustibles or other objects. In order to ensure a safe working environment, smoking is also prohibited. In fact, the fuel of lead smelting furnace mainly includes agglomerate, flux, coke, scrap iron and slag. The porosity of agglomerate is necessary and the particle size of coal cake is 50-150 mm. It is usually not necessary to add flux to lead smelting furnace when melting self agglomerate or agglomerate.
