copper ore concentrate smelting blast furnace metal & metallurgy machinery
copper ore concentrate smelting blast furnace metal & metallurgy machinery 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).

recycling gas rotary furnace for scrap lead battery other metal & metallurgy machinery
recycling gas rotary furnace for scrap lead battery other metal & metallurgy machinery Rotary smelting furnace A rotary furnace is a type of blast furnace, whose body is an inclined cylindrical container that can rotate. The principle of rotary furnace is to use the effect of high temperature and high-speed Redox to mix ore and coke together, rapidly heat and melt in the furnace, and separate metal and waste slag. The internal parts of the rotary furnace are divided into different areas, with the top layer being the combustion zone, where coke and oxygen react to produce high-temperature and high-pressure gas flow. The gas flows downwards and enters the reduction zone. The ore and coke undergo a reduction reaction in the reduction zone, and the metal is reduced out. The metal flows downwards along the furnace barrel and finally reaches the slag area, where it is separated from the waste slag. The rotary furnace has the advantages of high production capacity and high melting efficiency, and can melt various metal materials such as iron, steel, and alloys. In the steel industry, rotary furnaces have become one of the main steelmaking equipment, widely used in fields such as steelmaking, ironmaking, and scrap recovery.

tilting rotary type melting furnace for aluminum and scrap lead battery copper gas fired
tilting rotary type melting furnace for aluminum and scrap lead battery copper  gas fired Rotary tilting refining furnace The rotary tilting refining furnace is mainly used for the pyrometallurgical refining of recycled metals (mostly used for impure copper). In order to improve the technical and economic comprehensive indicators of the tilting refining furnace, it is best to have a copper grade higher than 90% when entering the furnace. For raw materials with lower copper grades, it is best to first undergo pre-treatment in the blast furnace and blowing furnace before entering the tilting furnace. The furnace body of the rotary furnace is installed on a rotating frame, which, under the action of a hydraulic cylinder, can tilt the furnace body within a certain angle range to achieve process actions such as feeding, melting, and dumping slag. At the same time, the furnace body can rotate around its axis under the action of the transmission mechanism; The rotary motion improves the heating efficiency of the furnace and is of great significance for the overheating of the molten metal. When melting metal in this furnace, a certain amount of slag forming agent needs to be added. The molten slag forming agent and slag liquid have a protective effect on solid and liquid metals, which can prevent metal oxidation The burning loss rate of elements such as silicon and manganese in a rotary cupola is equivalent to that of a coke burning cupola. The content of carbon elements in the rotary furnace is decreasing, so it is necessary to add a certain amount of carburizing agent (coke or graphite) to the furnace material.

other metal & metallurgy machinery lead casting machine lead battery scrap recycling
other metal & metallurgy machinery lead casting machine lead battery scrap recycling Aluminum lead ingot casting machine The aluminum or lead ingot casting machine is composed of a frame, ingot mold, demolding mechanism, main transmission mechanism, water cooling device (or water spray cooling device), aluminum liquid distributor, etc. This machine is not only used for aluminum ingot casting, but also for zinc ingot casting and aluminum based intermediate alloy waffle ingot casting. The aluminum liquid in the melting furnace flows through the aluminum liquid flow channel to the pouring flow channel and enters the distribution drum of the aluminum ingot casting machine. The distribution drum operates synchronously with the operating speed of the ingot casting machine. The distributor has several evenly distributed aluminum ports, each port aligned with the operating aluminum ingot mold. The flow rate of aluminum liquid during pouring is synchronized with the speed of the ingot casting machine, ensuring the depth of aluminum liquid in the aluminum ingot mold. This equipment is widely used in manufacturers of aluminum alloy ingots and zinc alloy ingots. It has the characteristics of automatic aluminum water distribution, adjustable casting speed, automatic ingot tapping and demolding, high production efficiency, uniform aluminum ingot weight, no large or small ends, and smooth surface. The casting process has a high degree of automation and low labor intensity. The casting mold is made of ductile iron, with a long service life、
