In the metallurgical industry, the importance of the blast furnace as a key thermal equipment is self-evident. However, some customers ask what unique advantages a blast furnace has compared to other kilns.
1.Characteristics and advantages of blast furnaces
(1)Multifunctionality
Blast furnaces can process various primary and secondary materials and are a type of multi-purpose smelting equipment.
(2)Improve efficiency and output
Using oxygen-enriched air in blast furnaces can accelerate the smelting process and increase output.
(3)Improvement of environment and quality
The amount of ash generated in the blast furnace is reduced or eliminated, thereby reducing the use of additives and related costs. At the same time, using oxygen-enriched air can reduce flue gas emissions and improve the operating environment.
In addition, the pig iron produced is of higher quality, with less or no slag, requiring no additional processing.
(4)Adaptability
Blast furnaces are suitable for various production capacity requirements, especially for production with an annual capacity of less than 50,000 tons.
(5)Cost-effectiveness
Reducing slag and ash content can lower raw material and transportation costs.
2.Diversified applications of blast furnaces
Blast furnaces have a wide range of applications, extending far beyond any specific field.
(1)Iron and steel industry
Blast furnaces are mainly used in the steel industry for ironmaking, providing raw materials for subsequent converter steelmaking.
(2)Non-ferrous metal smelting industry
It also plays an important role in non-ferrous metal smelting. For example, blast furnaces are often used in the smelting process of metals such as copper, lead, and zinc.
(3)Application of specific processes
In certain specific processes, there have also been attempts at steelmaking using blast furnaces. At this time, it is mainly used to process special raw materials or recycle scrap steel.
The diverse applications of blast furnaces fully demonstrate their strong adaptability and flexibility as a general-purpose smelting equipment, enabling them to meet the production needs of different industries.
3.Price and efficiency of blast furnaces
When evaluating equipment purchases, the price of blast furnaces is undoubtedly one of the key factors that companies need to consider.
Blast furnaces have high production efficiency and low unit energy consumption. Therefore, in the long run, its operating costs have a clear advantage.
In addition, using high-quality refractory materials, such as high-alumina bricks or clay bricks, can effectively extend the furnace lining life, thereby reducing costs.
Therefore, choosing a suitable refractory brick manufacturer is also crucial. Although high-quality refractory materials have a higher unit price, they can effectively reduce the frequency of furnace shutdowns for maintenance, thus resulting in better overall economic benefits.
