Effective Controlled Method Adding Carbon into Molten Steel to Produce 55Q Steel

Abstract:

It is very important to produce 55Q steel with the exact carbon content. Low and inconsistent carbon elemental recovery problems are often encountered when adding pig iron, or carbon powder into the baths of light rail steel. This is the case because carbon presents some of the following characteristics: lower density much more than the molten steel, low solubility in the liquid steel, high affinity due to oxygen. These circumstances lead to difficulties or risks, such as: poor or erratic recovery of alloying carbon element, violent and dangerous splashing, adverse environmental impact. To counter these problems existed in conventional method, carbon cored wire was prepared and wire injection process introduced in this work, and the effects of parameters such as feeding rate, etc on carbon recovery are investigated. The results show when using the carbon wire injection method, stable carbon addition is obtained, that is, the mean recovery of the carbon absorption is 90%, and what's more, the carbon content is under control accurately and environment improved.
