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

  • 120T lead battery scrap refining pot table lead acid battery recycling machine 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

  • china factory sell directly 10KG TO 1000KG electric induction smelting furnace for melting iron copper aluminum An induction furnace with a frequency range of 150 to 10000 Hz is called an intermediate frequency induction furnace. The medium frequency induction furnace is a special smelting equipment suitable for smelting high-quality steel and alloys. It has advantages such as fast melting speed, high production efficiency, strong adaptability, flexible use, good electromagnetic stirring effect, convenient start-up operation, and steel liquid being covered by slag (reducing atmospheric pollution of steel liquid). The complete equipment of the medium frequency induction furnace includes: power supply and electrical control part, furnace body part, transmission device, and water cooling system. The medium frequency induction furnace is particularly suitable for large, medium, and small furnaces with a capacity of tens of tons of 10kg. It is used for melting steel, cast iron, copper, aluminum, and other non-ferrous metals and their alloys, as well as insulation of liquid metals. It has strong adaptability to furnace materials and is suitable for intermittent operations. The furnace structure and usage are similar to those of a power frequency coreless induction furnace. Since the 1970s, with the increasing power and reliability of high-efficiency, static, and metal saving thyristor intermediate frequency power supplies, intermediate frequency furnaces have developed rapidly both domestically and internationally. They not only have obvious advantages in small and medium-sized capacity, but also are replacing industrial frequency heartless induction furnaces in large capacity. [1]

  • simple slag salvaging machine semiautomatic slag castching equipment Salvaging slag machine The horizontal groove of the slag extractor is welded from steel plates and profiles, and is divided into two layers: upper and lower. The upper tank is equipped with cooling water, the bottom is paved with wear-resistant steel plate for hot slag cooling granulation, and the lower layer is paved with Diabase wear-resistant cast plate. The upper tank of the slag extractor is generally connected to a closed door to seal the bottom and improve the thermal efficiency of the boiler. The ash scraped by the scraper chain will be discharged through the inclined upward section of the chute to reduce the water content of the slag and ensure that it does not exceed 25%. The upper and lower chutes of the inclined upward section are laid with wear-resistant cast plates, with a service life of no less than 30 years.
