Luoyang Judian Metal Hot Processing Equipment Co., LTD is mainly engaged in the manufacture of complete sets of equipment in the metal thermal processing industry and the integration of the entire production line.
During the smelting process, different types of furnaces can be selected depending on the material and scale of operation. The main smelting furnaces include:
Blast furnace:
Used to smelt iron ore to produce pig iron, which is the raw material for steelmaking. Blast furnaces use coke, iron ore and limestone at high temperatures.
Electric Arc Furnace (EAF):
Used to melt scrap metal and sometimes iron ore. The EAF uses electrical energy to generate the required heat.
Reverberatory Furnace:
Used to smelt non-ferrous metals such as copper, lead and tin. It smelts by reflecting heat from the top to the material.
Induction Furnace:
Uses electromagnetic induction to heat and melt metals, commonly used to smelt non-ferrous metals and recover metals.
Cupola:
Cylindrical furnace used to smelt iron and alloys. The operation is similar to that of a blast furnace but on a smaller scale.
Rotary Kiln:
A long, rotating cylindrical furnace used to slowly and evenly heat ores such as nickel and zinc ores.
Flash smelting furnace:
used for copper and nickel concentrates, using the energy released by the oxidation of the concentrate for smelting.
Depending on the needs and expected results of the smelting process, choosing the right furnace has specific applications and advantages.
There are many types of melting furnaces, and the specific choice depends on the melting materials, process requirements and production scale. The following are some common types of melting furnaces:
Electric furnace:
Electric arc furnace (EAF):
uses arc heat to melt metal, often used for the treatment of scrap steel and other metal waste.
Induction furnace:
uses the principle of electromagnetic induction to generate eddy currents inside the metal to generate heat, often used for the melting of non-ferrous metals.
Fuel furnace:
Oil furnace: uses fuel combustion to generate high temperature to melt metal.
Gas furnace:
uses natural gas, coal gas and other gases as fuel, which may have environmental protection and energy efficiency advantages.
Hybrid heating furnace:
Oil-electric hybrid heating furnace:
combines the advantages of fuel and electric heating, and can adjust the heating method and temperature as needed.
Special purpose furnace:
Melting furnace specially used for special materials or process requirements, such as ceramic melting furnace, glass melting furnace, etc.
In short, choosing the right furnace type depends on the specific melting needs and process conditions. In actual applications, factors such as energy efficiency, environmental performance, and maintenance costs must also be considered. Please note that the above information is for reference only, and the actual selection should be made based on specific needs and conditions.
