Industrial lump coal for steel mills: ensuring steel production from the source.
1. What is lump coal?
First, let's take a brief look at lump coal. Lump coal, as the name suggests, is a type of coal that is shaped as a lump. It is usually formed by compression and cementation of multiple small particles of coal, and has high combustion performance and stability. In the field of steel mill industry, lump coal is widely used in blast furnace ironmaking, converter steelmaking and other links.
Second, the importance of industrial lump coal in steel mills.
Coal is one of the indispensable and important raw materials in the steel production process. High-quality lump coal not only improves the combustion efficiency of coal, but also reduces the fluctuation of fuel in the furnace, thus ensuring the stability and continuity of steel production. In addition, lump coal also has a high level of safety during transportation, storage and loading and unloading.
3. How to select and identify the quality of industrial lump coal in steel mills?
In order to choose the right lump coal for steel mill industry, we need to pay attention to the following points:
1.Ash (AD) and sulfur (ST, AR) of coal: Ash and sulfur are important indicators to measure the quality of coal. High-quality lump coal should have a low ash and sulfur content to ensure environmental performance in the ironmaking and steelmaking process.
2.Volatile matter (VD): Volatile matter is the product of thermal decomposition of organic and inorganic matter in coal. Coal with higher volatile content is prone to ** or spontaneous combustion when burning, so choosing lump coal with lower volatile content can reduce potential safety hazards.
3.Particle size distribution of lump coal: The particle size distribution of lump coal has an important impact on combustion performance and stability. In general, smaller particles are easier to burn, but oversized particles can make transportation and storage more difficult. Therefore, choosing the appropriate particle size distribution is one of the key factors to ensure the quality of lump coal.
When identifying the quality of lump coal, we can use professional testing instruments for laboratory analysis, or refer to the reputation and reputation of the leading businessmen. In addition, observing the appearance characteristics such as color, gloss and structure of lump coal is also an important means to judge its quality.
4. How to store and transport industrial lump coal in steel mills?
When storing and transporting lump coal for industrial use in steel mills, the following points need to be noted:
1.Storage: When storing lump coal, choose a dry and well-ventilated place to avoid direct sunlight and rain. At the same time, it is necessary to regularly check the humidity and volatile content of coal, and take timely measures to prevent spontaneous combustion or **.
2.Transportation: When transporting lump coal, a carriage or ship with good sealing performance should be selected to avoid leakage and combustion of coal during transportation. In addition, it is necessary to arrange the transportation route reasonably to ensure the safety of transportation.
5. How to choose a reliable steel mill industrial special lump coal supplier?
Choosing a reliable steel mill industrial lump coal supplier is the key to ensuring the quality of coal. When choosing a quotient, we can consider the following:
1.Qualifications and credibility of businessmen: Understand the qualifications and past performance of businessmen, and choose businessmen with good reputation and qualifications.
2.*Comparison with quality: while comparing **, pay attention to whether the quality of lump coal provided by ** merchants meets the requirements.
3.Contract agreement and acceptance: sign a contract with the best businessman to clarify the quality standards and acceptance methods. After the coal arrives, the acceptance will be carried out in accordance with the contract to ensure that the coal quality meets the requirements.
In short, the industrial lump coal of steel mills is of great significance to ensure the stability and continuity of steel production. Understanding how to select and identify lump coal quality, storage and transportation methods, as well as choosing a reliable supplier is key to ensuring the quality of coal.
