What Is The Difference Between A Furnace And A Blast Furnace

Smelting furnace and blast furnace are both commonly used metallurgical equipment. But there are some differences in their working principle, application areas, furnace structure and other aspects. We are a professional manufacturer of carbonisation furnace. Here is a detailed introduction for you.

What Is The Difference Between A Furnace And A Blast Furnace？

Working principle:

Melting furnace is usually used to melt metal or add heating materials. Metals and other materials can be added to the melting furnace body. After being heated at a high enough temperature, they can be dissolved and softened. The heat source of the melting furnace is through electric heating, electric current or other means such as flame. It depends on the material of its furnace.
A blast furnace is a device used to smelt iron. Inside the blast furnace, iron ore and coke are reacted under high temperature and high pressure atmospheric conditions. Separation of the iron ore’s metallic minerals and other impurities is achieved. The fuel used in a blast furnace is usually coke, natural gas, etc. The fuel is burned to a high temperature. The fuel is burned and heated to produce heat that can be used to heat the iron ore in the furnace.

Usage Scenarios:
Smelting furnaces are primarily used to recycle and reclaim metals. It can be used to make some alloys and other materials. There are many types of melting furnaces, including: electric arc furnace, frequency induction, heating furnace, oxygen combustion furnace and so on. The type of furnace to be used depends on the customer’s required capacity, cost of production, nature of the material etc.
Blast furnaces, on the other hand, are used to produce iron and are an important part of steel metallurgy. Blast furnaces allow for mass production in the iron and steel industry. It can also contribute to the industrial revolution.

Furnace material:
The material of the melting furnace is mainly made of: carbon steel, stainless steel, copper and so on. The lining of the furnace is usually made of refractory materials. Thus, it is resistant to high temperatures and corrosion.
Blast furnace is made of concrete and steel. The exterior is lined with refractory bricks. The interior of the blast furnace can withstand extremely high temperatures and pressures. Therefore very strong and wear-resistant materials are used to protect the furnace body as well as other accessories.
