2012-11-26
The 3rd largest steel plant NLMK (Novolipetsk Steel) in Russia set up a new type of steel batch refining furnaces. The annual capacity will be increased to 2 million metric tons, which is a great help for the factory to seek for car manufacturing, mechanical industry, and construction engineering customers.
The capacity of the new type of steel batch refining furnace APK-1 can be 2 million metric tons. According to the estimated current utilization, about 1.6 million metric tons of refined steel batches can be produced per year. To see from the operation scale of NLMK, it can be said that all steel can go through the secondary metallurgy processing.
The steel batch refining furnace APK can do helps to sort out grades and classes of products, such as new rolled plates, standard steel plates with the sulfuric content under 0.001-0.002%, steel plates with more precise refined alloy parameters, or the increase of the purity of steel in plates. Metallurgical products processed by APK are mostly used in car manufacturing, construction, home appliances, and other electric engineering. The products cover types of low carbon, general carbon, and low alloy steel materials.
After APK-1 is installed, NLMK has started to manufacture the second refining furnace since this April. This furnace is going to be built with the cooperation with Austrian Siemens VAI in order to draw up a blueprint of the modern steel plant.
Notes:
The furnace of NLMK is quite precise and complicated, built on 4 main sub-furnaces and the efficiency is up to 12 million metric tons per year. The structure includes 10 parts to deliver molten steel through the electric arc and 2 cycling deoxidation mechanisms (with the efficiency of 400 thousand metric tons per year). In addition, NLMK began the production of No. 2 converter in September 2011, increasing the efficiency of cycling deoxidation to 4 million metric tons per year.
