In ironmaking production, maintaining the stability of blast furnace operations is crucial. Key parameters influencing this stability include furnace temperature, ore batch weight, slag alkalinity, charge ratio, wind pressure and temperature, and top pressure. Furnace temperature Maintaining stable furnace temperature helps keep the drop zone height proper, stabilize the differential…
Under the condition of using solid carbon fuel (coke + pulverised coal) in conventional blast furnace, reducing carbon fuel consumption is the most direct and effective measure to reduce CO2 emission. In the iron and steel industry, by around 2030, the fuel ratio of blast furnace should be generally reduced…
Blast furnace is a black box, how to understand the various changes within the blast furnace well, one way is to reference the anatomy of the blast furnace, supplemented by a variety of theoretical calculations and practical experience to deduce the changes within the furnace; another way is to apply some visualisation technology to…
Blast furnace charging operation refers to the control of the position and thickness of the furnace charge in the blast furnace production process, so as to adjust the key technical and economic indicators such as the permeability of the charge column and the utilisation of gas. The charging system is…

New or expanded bars or wire rod production line is mostly used in H/V arrangement of short-stress rolling mill, it is compared with the traditional mill, this compact rolling line reduces the weight of equipment and plant construction costs. The characteristics of the short stress rolling mill: The rigidity of the mill is good, and the dimensional…
The rolls of hot rolling mill or cold cooling mill act key role in the rolling process. The shape (convexity, concavity, taper,etc) of the roll can impact the quality of final products. In the rolling process along the length of the roll, the distance between the upper and lower rolls should…
The smelting process for the production of stainless steel is mainly divided into one-step, two-step and three-step, of which the two-step process of EAF+AOD (Electric Arc Furnace+Argon Oxygen Refining Furnace) accounts for about 70%, and the three-step process accounts for about 20%. With the low phosphorus iron is widely used…
Titanium is an element with an atomic number of 22 in the periodic table, a subgroup element of the fourth period, which includes zirconium and hafnium in addition to titanium, and is characterized by a high melting point and a stable oxide film on its surface at room temperature. Characteristics…
Duplex stainless steel (Duplex Stainless Steel, referred to as DSS), refers to the ferritic and austenitic each accounted for about 50%, generally the content of the lesser phase of the stainless steel needs to reach a minimum of 30%. 2205 stainless steel (S32205) due to the austenitic stainless steel compared…
