Mintal Group is the largest manufacturer of high carbon ferrochrome in China, and largest commercial stainless steel manufacturing base in northern China. Its major clients include Baosteel, Tisco, Jisco, Zhangjiagang Pohang, and Guangzhou Lianzhong. Mintal Group was ranked top 3 in the “Top 100 Fastest Growing Companies of China” award and “Best Iron and Steel Companies of China”.
Currently, Mintal Group has introduced world advanced ferrochrome production technology from Outotec, Finland. The technology was awarded “Clean Technology Prize” by Finland, and “Best Available Technology” by EU. Mintal Group plans to invest about 3,000,000,000 RMB to set new ferrochrome plant in Jiuyuan Industrial Park. The new plant is very energy efficient and environmental friendly. Its unit power consumption level is 20% lower than industry average. Its emission is 60% lower than industry average. Mintal Group aims at becoming one of the top players in the industry.
Mintal Group Strategic goal is " Keep a global vision; build the top Chromium Circulation Base in China and dopt the best available technology and provide the best products to the customers."
Mintal Group introduce pellets belt roasting oxidation technology from Outotec. The annual output is 700,000 tons SBSTM chrome pellet. SBSTM chrome pellet is mixture of chrome concentrate with small amount of coke fines, through milling, filtrating, pelletizing and sintering, etc.
(1)Symmetrical small size, it is helpful to improve the burden permeability and balance airflow.
(2)High intensity, it will not been crushed easily during transportation, storage and loading.
(3)High metallurgy property and bulk intensity, it will help to increase production output and decrease energy consume.
(4)High reducibility, it can improve the usage of furnace chemical energy. The Cr2O3 content of SBSTM chrome pellet is higher than 42%, the physical property fulfill the YB/T 005~006-91 standard.
The size of SBSTM chrome pellet is 6-12mm. The qualified size is more than 98%, only less than 1% lower 6mm size.
High Carbon Ferrochrome – Base Material of Stainless Steel
High carbon ferrochrome is a carbon reduction product intermittently outgoing from the furnace. It is produced from ferrochrome minerals in the electric smelting furnace for continuous smelting by using the silica as flux and carbon as reducing agent.
High Carbon Ferrochrome is the solid solution of chromium, ferrum and carbon, complex compound of chromium, ferrum and carbon. The essential component is (Cr、Fe)7C3, silver-white metal, brittle. The specific weight is 6.5-6.7g/cm3, bulk specific weight is 3.8-4.0t/m3. The melting point is 1550℃, electric conduction. High Carbon Ferrochrome fulfill GB/T5683-1996 standard.
