copper lead zinc tin ore smelting air blast furnace from lufeng machinery factory
copper lead zinc tin  ore smelting air blast furnace from  lufeng machinery factory Blast furnace function Blast furnaces can be used for matte smelting of metals such as copper, nickel, cobalt, and reduction smelting of metals such as lead and zinc. They can also be used for melting miscellaneous copper and processing other materials. The charge of a blast furnace is generally block shaped, and the fuel is coke. The furnace materials are added in batches from the top of the furnace to form pillars. Air is blown in from the lower tuyere, and coke burns in the tuyere area, forming a high-temperature melting zone; The furnace material reacts fiercely here and continuously melts. During reduction smelting, the melt clarifies in the furnace hearth, releasing metal and slag separately. During matte smelting, the melt flows into the front bed through this bed, clarifying and separating matte and slag. During the process of hot flue gas passing through the furnace material and rising to the furnace top for discharge, the furnace material is preheated (during smelting and kneading of concentrate, it also causes the concentrate to sinter), and partial smelting chemical reactions occur. So the blast furnace has good heat and mass transfer conditions, high thermal efficiency, and a large daily production capacity per unit area (i.e. bed energy rate).

customized size melting refining furnace stove for lead acid battery recycling machine gas burner system
customized size melting refining furnace stove for  lead acid battery recycling machine gas burner system Reflection refining furnace The present invention discloses a bottom blowing process for alkaline refining of regenerated lead by fire method. After the crude lead liquid is poured into the refining furnace from the melting furnace, argon gas is introduced from the bottom. When the temperature of the lead liquid drops to about 330 ℃, slag is skimmed, and the lead copper content is reduced to about 0.1% by melting and removing copper. After skimming, sulfur powder is sprayed into the bottom of the refining furnace to further remove copper. The temperature is raised to 450-480 ℃, and the reaction is carried out for 30-60 minutes. The sulfide slag is removed to complete the copper removal process; When the lead liquid temperature is about 450 ℃, powdered Sodium nitrate and sodium hydroxide are blown from the bottom of the refining furnace. After reaction for 30min, NaCl powder is blown from the bottom of the refining furnace with argon gas to complete the arsenic, antimony and tin removal process. The loss of said bottom blowing process method, refining agent and/or alloy is greatly reduced; There is only inert gas with low solid solubility in the lead liquid, which is not easily oxidized by the lead liquid and lead ingot. There is no lead slag inside the lead liquid and lead ingot. When using recycled lead, there is less lead slag and the slag yield is low; During the refining process, the surface of the lead liquid is always protected by argon gas, which can be used for high-temperature Ag removal operations. The regenerated lead contains low Ag content; The argon gas blown into the bottom will float together with small bismuth compound particles, resulting in low bismuth content in lead ingots

scrap lead battery refining furnace smelting kettle pot cover
scrap lead battery refining furnace smelting kettle  pot cover Lead pot cover The cover plate is composed of 10mm thick steel plates 5) Furnace insulation cover (movable): outer layer 6mm, inner layer 60mm Heat insulation (the furnace insulation cover is formed by one-time stamping, Manual lifting, capable of 360 degree rotation)   Cover for lead pot The utility model discloses a lead pot cover that is convenient for removing slag from lead liquid, and relates to the technical field of battery production. The utility model includes a lead pot cover and a slag removal device; The lead pot cover includes a cover ring and a cover plate; The upper surface of the cover plate is provided with a radially arranged rectangular groove; The bottom surface of the rectangular groove is provided with a slag removal port; One side of the slag removal port is fixedly connected with a conduit side by side; The slag removal device includes a fixed rod that matches the surface inside the conduit; Two fixing rods are fixedly connected with a handle on the upper and lower sides through a connecting block; A Rectangular cuboid slag leakage box is fixedly connected with the side faces of the lower ends of the two fixed rods through a connecting block. The utility model seals the lead pot by setting a lead pot cover matched with the lead pot, which solves the problem that the lead liquid in the existing lead pot is easy to contact with oxygen to produce lead slag, which affects the product quality; At the same time, the slag removal device can perform the slag removal operation without removing the lead pot cover, providing convenience for the slag removal of lead liquid and effectively ensuring the quality of lead liquid。
