Key Products and Specifications
Chinese manufacturers provide a variety of semi coke products. These products have specific features that meet different industrial needs. Here are the key specifications and product details:
Semi coke is essential in many industries. It is typically made with a carbon content of 83% to 86%, and the ash content is kept low, around 7-10%. The key feature is its sulfur content, which stays under 0.35%. This makes it highly valuable in processes like ferroalloy production.
In industries like steel and calcium carbide production, semi coke in sizes from 30-80mm down to powders under 5mm is crucial for efficiency. I visited a steel plant in Shanxi where they explained how semi coke with these exact specifications improved both blast furnace injections and foundry operations.
The advantages of semi coke go beyond lower sulfur and phosphorus levels. It helps reduce production costs while increasing chemical reactivity and electrical resistivity. These details make semi coke a vital raw material across various industries.
Main Production Regions
China has some of the largest semi-coke production areas in the world. These regions are spread across several provinces and play a key role in meeting the demand for semi-coke both domestically and internationally. Semi-coke is an important material for industries like steel production.
1. Shanxi Province
Shanxi is the largest producer of semi-coke in China, making up over 20% of the country’s total production. Key production areas include Shenmu County and Fugu County, which are known for their large operations and proximity to abundant coal resources.uperore.com
2. Inner Mongolia
Inner Mongolia ranks second in semi-coke production. The production is concentrated around Ordos City and Wuhai City, where easy access to coal plays a major role in the region’s output.
3. Xinjiang
Semi-coke production in Xinjiang is growing quickly, especially in Hami Prefecture and Turpan Prefecture. These regions are seeing more investment, making them important to China’s expanding semi-coke industry.
4. Guizhou Province
Guizhou Province is becoming an important player in the semi-coke market, with production facilities in Liupanshui City. The province has abundant coal resources and its growing infrastructure is boosting production capacity.
5. Shaanxi Province
Shaanxi Province, with key production in Yulin City and Shenmu County, continues to be a major contributor to China’s semi-coke supply. Its coal-rich regions make it a crucial part of the semi-coke supply chain.
These five regions together produce around 60% of China’s semi-coke, showing their importance in the industry. Their coal-rich locations ensure easy access to raw materials and efficient production.uperore.com
Typical Applications
Semi-coke from China is popular in many industries because of its unique properties. Here are some common uses of semi-coke:
Semi-coke is now a key material in many industries, especially in ferroalloy production. From what I’ve seen, semi-coke is crucial in producing ferrosilicon and silicomanganese. It improves both the quality and energy efficiency of the final products. Compared to traditional coke, semi-coke reduces energy use and costs. This is important for profitability in these industries. For example, I visited a steel plant in Shanxi, where they switched to semi-coke for blast furnace injection. The results were impressive: the process became more efficient, and the output improved.
Semi-coke also has high carbon content and low impurities, which makes it valuable in chemical applications. It’s especially useful in producing activated carbons and sorbents, making the manufacturing process more sustainable and cost-effective. Its flexibility and benefits are clear. It’s not just a fuel, but a true game-changer in industrial production.
