What’s wrong with the temperature of the molten pool being too high or too low in the Steelmaking and blowing process?

What’s wrong with the temperature of the molten pool being too high or too low in the Steelmaking and blowing process? key word: Steelmaking and blowing Too high: Difficult to convert the slag. If the temperature is too high, the decarburization reaction becomes more intense, causing the FeO in the slag to maintain a very…

The drawing illustrates and briefly analyzes the changing law of the decarburization rate during the blowing process.- steelmaking decarburization

The drawing illustrates and briefly analyzes the changing law of the decarburization rate during the blowing process.- steelmaking decarburization Keywords: steelmaking decarburization In the early stage of blowing, due to the greater affinity between Si and oxygen, Si rapidly oxidizes, and the decarburization rate is small. As the oxidation of Si ends and the temperature…

What are the basic conditions for steelmaking dephosphorization? Write the chemical reaction formula.

What are the basic conditions for steelmaking dephosphorization? Write the chemical reaction formula. Keywords: steelmaking dephosphorization Under steelmaking conditions, P cannot be directly oxidized and removed by oxygen. Only the combination of oxides (P2O5) and (CaO) to generate stable and complex compounds can be effectively removed. The influencing factors are: (1) Slag basicity: Increasing R…

What are the three stages of furnace steel conversion? What is the law of the decarbonization reaction in each stage?

What are the three stages of furnace steel conversion? What is the law of the decarbonization reaction in each stage? key word:Furnace steel blowing, steelmaking decarburization Generally speaking, the conversion of a furnace of steel can be divided into three stages: the initial stage, the middle stage and the final stage according to the characteristics…

Design and Analysis of Continuous Straightening of Arc Continuous Casting Machine

The function of the tension leveler The arc continuous casting machine is the main force in the production of cast billets in the iron and steel industry. Square billets, rectangular billets and round billets are generally produced by arc continuous casting machines, occupying a dominant position, even if the continuous casting machine adopts a straight…

refining equipment outside the ladle furnace

6 common types of refining devices outside the ladle furnace and the types of refractory materials used

The ladle degassing refining method is the main method of refining outside the furnace (also known as secondary steelmaking). Out-of-furnace refining is the process of transferring the molten steel smelted in a roughing furnace (electric furnace and converter) to another high-temperature vessel (mainly a ladle) for refining: Refining is a process of using different metallurgical…
