Please briefly describe the six major hazards of non-metallic inclusions on steel.
Stress concentration and cracking occur in the internal structure of the steel.
What are the main measures to increase the age of the converter?
Using computer dynamic control, that is, optimal smelting control, to improve the end point hit rate, that is, shorten the smelting cycle.
What is the role of converter slag in the steel making process?
Prevent a large amount of heat loss, prevent the oxygen flow from strongly impacting the molten pool; reduce metal splashing;
Xinyue Enterprise Culture
To promote steel industry, to represent Made in China
What is the converter type, and what are the basis for selecting the converter type?
The converter type refers to the geometry of the inner shape of the converter after bricklaying. The following factors should be considered when selecting a converter furnace type
In hot metal pretreatment, why does dephosphorization of molten iron have to be desiliconized first?
The hot metal pre-desiliconization technology was developed based on the hot metal pre-dephosphorization technology.
