In Russia and China the abundance of low Mn ores could have been a driver for keeping the blast furnaces running. In Japan, the decision of building an FeMn blast furnace was taken by the then Kawasaki Steel under the circumstances of the second oil crisis, to replace two SAFs with one blast furnace, in a plant supporting high electricity cost.
Inordinate levels of heavy metals in water sources have long been a matter of concern, posing serious environmental and public health risks.

The quality of raw materials (iron ore, coal, and coke) has a clear impact on the carbon emissions of the hot metal production in steel making. So far, very little work has been done to measure and quantify this impact. Yet for benchmarking, technology choice and general carbon optimization are important elements. The total slag production of a blast furnace gives …
In the process of gas granulation of blast furnace slag, a cyclone separator serves to cool slag particles and separate them from hot air. This study focuses on modelling the cooling of slag particles in a cyclone separator. Simulations revealed the airflow field, temperature field and particle trajectory distribution within the cyclone separator. Key parameters such as …

Blast furnace No. 5 of Severstal is the largest in the Russian Federation; it has a useful capacity of 5580 m3 and design capacity of 4 million tons of cast iron per year. At present, a part of the blast-furnace slag from the furnace is wet-granulated, with a granulated slag output of up to 1 million tons per year. Instead of a rather sim-
An important measure is the heat recovery of solid waste (Sun et al., 2022). Blast furnace slag (BFS) is one of metallurgical solid waste (Peng et al., 2018) and is considered a by-product of pig iron due to the wide range of uses in human society (Wu, 2022), composed of CaO, Al 2 O 3, FeO, MgO, MnO, and SiO 2 (Qin et al., 2012).
Enrichment of blast furnace slag with a mixture of 0.05 mol of phosphoric acid H 3 PO 4 (85%) + 0.44 g of K 2 CO 3 as a powder and also different percentage, of a
1. Introduction. The steel industry as one of the most energy and carbon intensive industries, has attracted much attention in achieving the goals of carbon peak and carbon neutrality [1, 2].The treatment of liquid blast furnace (BF) slag, a by-product of the iron-making process, is one of the breakthrough points, since it contains a large amount of high-grade …

A blast furnace is a block that smelts ores, raw metals and metal armor and tools twice as quickly as a furnace but cannot smelt anything else. It also serves as an armorer's job site block. A blast furnace can be picked up using any pickaxe. If mined without a pickaxe, it does not drop. Blast furnaces drop their contents when broken. Blast furnaces can generate in any armorer house; …
