Coke blending is the process of automatically calculating the correct proportions of coking coal for the blast furnace. The process requires a combination of both theoretical and practical knowledge in order to produce a coking mixture of coals and raw materials that maximizes efficiency and minimizes costs.
To begin the coke blending process, the first step involves determining the weight and composition of the coal being used. This is done by measuring the moisture content, ash content, volatile matter, sulphur, and fixed carbon. These numbers will be used to assess the quality of the coal and to properly calculate the amount of fuel that is needed to reach the optimal output during the smelting process. The coal’s estimated calorific values should also be taken into consideration. Once the quality and quantity of coal is determined, the next step is to pair these numbers with other raw materials that are needed for the smelting process.
The raw material stage involves calculating the amount of coke breeze, coke grinding, and other additives that are necessary to mix with the coal and bring out the desired result. The amount of additives is dependent upon the specific blend and the amount of energy that is needed for the smelting process. Coke breeze is sometimes used to assist in making the final blend of coke and coal more even and to help hold the proper shape of the resultant mix. Coke grinding is also implemented in order to ensure the correct particle size of the coal and other raw materials.
Coke blending is a complex process that requires careful consideration of the specific coal being used, the other raw materials, and the desired result. If the process is followed properly then the resulting blend should contain a higher percentage of coke than the unblended coal and produce a more uniform mixture of raw materials. The purpose of coke blending is to produce a fuel that is cost effective and of the highest quality. Without proper knowledge and experience, the resulting blend could be inefficient and ultimately lead to a compromised smelting process. That is why it is important that companies seeking to employ the coke blending process find experienced professionals to ensure that their process is of the highest quality.
In conclusion, coke blending is a complex process which requires careful consideration of the coal, raw material ingredients, and desired result. With the right knowledge and experience, companies can produce a fuel which is cost effective, efficient, and of the highest quality. The amount of coke breeze and coke grind used should be carefully calculated and the moisture content, ash content, volatile matter, sulphur and fixed carbon should all be taken into consideration when creating the desired blend. This process is essential for creating a high quality fuel source which is optimal for the smelting process.
