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…

The process that continuous casting process produces alloy steel billets can improve the yield of alloy steel and reduce the loss of alloy elements ( some alloys contain precious metal elements).  Therefore, less cutting head can reduce the production cost, and because the quality of the casting billet produced by…

The tundish as a key device in the meltshop has some actual problems especially in billet continuous casting process as follows: (1) The inner cavity shape of tundish is unreasonable. The shape of the inner cavity influences the flow of molten steel in the tundish the residence time is short,…

Key words: High-efficiency, fine slag, crushing equipment,slag The complex structure of steel slag is a combination of slag and iron, which are intermingled with each other. Under the premise of ensuring the grade of magnetically selected slag steel (slag steel particles), steel slag is crushed to 75mm after magnetic separation,…
