NLMK Group has embarked on a project to implement stamp-charging technology at an operating coke oven battery at Altai-Koks, a leading Russian manufacturer of metallurgical coke.
This project, which is worth a total of 3.3 billion rubles, will boost coke quality and reduce the cost of its production, and improve the environmental footprint of operations.
Stamping technology is under implementation at coke oven battery No. 5, the biggest and the most advanced coke oven battery at Altai-Koks (which operates a total of five batteries). It was launched in 2006 with a design capacity of 1.1 million tons per year, and covers 25% of all Altai-Koks production needs. The battery will be overhauled and equipped with advanced and efficient off-gas collection and cleaning systems. Technology solutions are supplied by HuDe (Germany), a global leader in the field.
The scope of the project includes the construction of a new storage bunker equipped with stamping machines, and installation of conveyors and machines for loading stamped charge into the oven. Set-up and start-up operations are planned for autumn 2019.
Instead of the conventional top charging method, stamped charging involves feeding already compacted coal briquettes into the oven horizontally. (NLMK/Ukrainian metal)
