All Qarmet blast furnaces switched to natural gas

The Qarmet Metallurgical Plant has completed the transition of blast furnace production to natural gas. This will reduce costs, increase the stability and environmental friendliness of production.

The construction of the gas pipeline started in 2024. Already in August 2025, natural gas was first supplied to blast furnace No.2. Furnace No. 3 was connected to the system in September, and the fourth furnace was connected at the end of October. All Qarmet blast furnace units are now fully powered by natural gas.

One of the important goals of the project was the complete abandonment of fuel oil and the transition to cleaner and more energy efficient fuels. Metallurgists have already eliminated the use of more than 250 tons of fuel oil per day.

Today, experts are focused on reducing coke consumption.

— I have been working in the blast furnace shop for 25 years, and for the first time we received natural gas. We master, we study, we already see the result. Productivity increased, coke consumption decreased, which led to a reduction in the cost of cast iron. This is a great achievement," said Askhat Serikbayev, head of the production site of blast furnace No. 4.

Modernization does not stop there. In 2026, it is planned to switch lime kiln, converter shop, galvanizing lines and thermal power plants to natural gas.
