Double Targeting in the End Control of converter steel-making Process and the Hazards of Post Blowing
Abstract
The converters process is a very complicated process in the production of steel ingots, and it requires strict control of certain processes and parameters. This article mainly introduces the dual targeting in the end control of the converter steel making process. The dual targeting mainly refers to the double parameters that must be met in the end of the process. The double parameters are usually related to the temperature and carbon content of the molten steel. In addition, the article also discusses the hazards of post blowing caused by double targeting.
Keywords: steel-making, double targeting, end control, end parameters, post blowing.
1. Introduction
The Converter process is a complicated process that involves the production of steel ingots. In order to improve the quality of the steel ingots, it is necessary to strictly monitor and control certain process parameters. Of these parameters, the end control parameters are of great importance, as it is related to the temperature and the carbon content in the molten steel. The end control is typically performed by targeting two parameters at the same time, hence the term “double targeting”.
2. Double Targeting
The double targeting process is very important in the end control of converter steel making process. It is done in order to control the final composition of the molten steel. The double targeting process involves setting two parameters that must be met in the end of the process.
These two parameters are usually related to the temperature and the carbon content of the molten steel. The temperature parameter is related to the steel melting point, while the carbon content parameter is related to the amount of carbon that is present in the molten steel. The two parameters are set in a way such that they both must be reached in the end of the process.
3. Post Blowing
One of the most common hazards caused by double targeting is the post blowing. Post blowing is a situation where the final control parameters are not met and the molten steel is subjected to a blowing process to get the desired result. The blowing process involves introducing a jet of oxygen and carbon into the molten steel in order to reduce the temperature and increase the carbon content.
Although post blowing can be effective in controlling the composition of the molten steel, it can have serious adverse effects on its quality. The effects include brittle structure and weld weakness, as well as increased risk of crack formation due to the rapid cooling of the steel.
4.Conclusion
Double targeting is a very important process in the end control of converter steel-making process. The double targeting involves setting two parameters that must be met in order to get the desired composition of the molten steel. However, if the parameters are not met, the molten steel can be subjected to post blowing, which can have adverse effects on its quality. Therefore, it is important to keep an eye on the end control parameters and make sure that they are met.
