Deoxidation process of molten steel in EAF furnace Due to the oxygen blowing process in EAF furnace, a large number of alloys are also oxidized, such as Cr2O3, MnO, FeO, and a large amount of free oxygen remains in the steel. EAF furnace deoxidation method includes precipitation deoxidation and diffusion…

Deoxidation of molten steel is the last key process operation before casting, which is directly related to the metallurgical quality of cast steel. Deoxidation is also the basis of nitride enhancement and nodular modification of cast steel. Deoxidizer selection should follow the following principles: Compared with Fe, deoxidizer elements have…

There are six methods commonly used in the production of section steel. 1. Ordinary rolling method This method is carried out with a general two or three high mill. The pass is composed of two rolling grooves, which can produce ordinary simple, irregular and longitudinal rolling periodic section steel. This…

Hot rolling dust removal typically employs two methods: ventilation dust removal and spray dust removal. Ventilation dust removal uses a hood to collect fumes, conveying the dust through flues to subsequent dust collectors for purification. Spray dust removal involves spraying water mist to reduce the temperature of the fumes, increase…

Xingcheng Special Steel has successfully used continuous casting process to produce and develop 100mm thick 9Ni steel and passed the type test certification of nine countries Classification Society such as CCS and ABS. Marine 9Ni steel is mainly used in the storage and transportation of liquefied natural gas, and is…

During the heating process of steel, its color will show different characteristics as the temperature changes. 1. Low temperature stage (about 200-500 °C) The temperature is around 200-300 °C, and the steel surface begins to show a light yellow color . This is because at this temperature range, the surface…

Key updates on metallurgical standards, including graphene oxide analysis, high-strength steel, alloys, and advanced testing methods, effective May 2025.

AOD refining method is the abbreviation of Argon Oxygen Decarburization (Argon Oxygen Decarburization), in refining stainless steel, by reducing the partial pressure of CO, to achieve the effect of false vacuum, so as to make the carbon content down to a very low level, and inhibit the oxidation of chromium…

Fasteners, bearings, gears, springs, molds and dies are the basic parts of mechanical manufacturing, which directly affect the quality and reliability of machinery. Fasteners, bearings, gears, springs, molds and other service environment is different, the quality of the material requirements are also different. Fasteners steel Fasteners is the largest application…
