Lead Refining Furnace

Lufeng have been specialized in Lead Refining Furnace for many years. With complete production and testing equipment, it can make oval, dished and conical head lead pots of various materials (ASTM A285 Grade C,ASTM A516 Grade 70). With ∅500mm-10000mm and thickness of 20-100mm , as well as various non-standard heads according to customer requirements.

Lufeng tailor-made lead pot is supported by stove and covered by mobile cover. Inside the stove, there are refractory materials. The off-gas from lead refining pot and stove is collected and treated by dust collector. Lead pot is an indispensable equipment in lead fire refining.

Our lead refining furnace system can meet the requirements of daily refining in terms of performance and strength, and has the following advantages:

(1) Lufeng lead pot with Simple structure and low cost;

(2) Lufeng can also provid Compact installation configuration;

(3) Qualified pure Lead products based on lead bullion composition and client requirement.; Completed system can be designed based on site condition.

(4) Our lead pot products are widely used in lead smelters.

(5) Lufeng provides domestic and foreign customers with different capacity from 5T to 150t lead pots , which has good application effect and has been recognized by customers

The lead pot of lead refining furnace system is made of heat-resistant boiler steel(Foreign material brand ASTM A285 Grade C or ASTM A516 Grade 70), which can meet the working environment of high temperature. Automatic submerged arc welding machine is used for double-sided groove welding to ensure welding strength. Lufeng has rich experience in lead pot loading and delivery. 5-120t Lead pot The supply period is about 45 days, and the goods are delivered with steel structure support or bare assembly

  • lead refining furnace table for lead acid battery manufacturing plant 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
