In building lead materials, in addition to the use of lead plate, pipe, solder, there are also lead mesh for plugging; A considerable part of the above lead tin solders, as low melting point fusible alloys (alloys of lead and tin, bismuth, cadmium, indium, etc.), are almost all wire materials. The lowest melting point of the latter is below 100 ℃, which is used for automatic arc extinguishing, electric fuse, boiler plug, etc.

The production of lead products is being transformed to the mode of bottom blowing furnace+side blowing reduction furnace+fuming furnace. The transformation of lead product smelting technology not only greatly improves the output and quality of lead products, but also reduces the energy consumption in the lead smelting process and further improves the energy utilization rate. It is believed that with the continuous progress of lead smelting technology, the supply of lead products in China will gradually meet the needs of China's industry for lead products.
