Embodiment 1

[0023] The present invention provides the following technical proposal: a method for further research on the number of continuous pouring furnaces in secondary steelmaking, comprising the following steps:

[0024] 1) First, formulate a reasonable and effective tundish baking system, so that the tundish baking time is controlled within 2 hours, and the production mode of adding a cover is adopted on the tundish, so that when baking is required, the cover can effectively shorten the waiting time for pouring Time, when the tundish is required to cease fire, the cover can be opened, thereby shortening the waiting time and temperature drop of the tundish to cool down, and ensuring that the tundish baking temperature is 900°C when pouring is started;

[0025] 2) Ensure that the thickness of the tundish slag layer is controlled at 70mm to reduce the erosion of the tundish slag line. When dealing with the slag overflow port, prevent its operation from causing damage to it, and reduce ...

Embodiment 2

[0032] The present invention provides the following technical proposal: a method for further research on the number of continuous pouring furnaces in secondary steelmaking, comprising the following steps:

[0033] 1) First, formulate a reasonable and effective tundish baking system, so that the tundish baking time is controlled within 2.5 hours, and the production mode of adding a cover is adopted on the tundish, so that when baking is required, the cover can effectively shorten the waiting time for pouring Time, when the tundish needs to cease fire, the cover can be opened, thereby shortening the waiting time and temperature drop of the tundish to cool down, and ensuring that the tundish is baked at a temperature of 1000°C when pouring is started;

[0034] 2) Ensure that the thickness of the tundish slag layer is controlled at 55mm to reduce the erosion of the tundish slag line. When dealing with the slag overflow port, prevent its operation from causing damage to it, and red...

Embodiment 3

[0041] The present invention provides the following technical proposal: a method for further research on the number of continuous pouring furnaces in secondary steelmaking, comprising the following steps:

[0042] 1) First, formulate a reasonable and effective tundish baking system, so that the tundish baking time is controlled within 3 hours, and the production mode of adding a cover is adopted on the tundish, so that when baking is required, the cover can effectively shorten the waiting time for pouring Time, when the tundish is required to cease fire, the cover can be pulled open, thereby shortening the waiting time and temperature drop of the tundish to cool down, ensuring that the tundish baking temperature is 1200°C when pouring is started;

[0043] 2) Ensure that the thickness of the tundish slag layer is controlled at 34mm to reduce the erosion of the tundish slag line. When dealing with the slag overflow port, prevent its operation from causing damage to it, and reduc...

Abstract

The invention relates to the technical field of double steelmaking tundish continuous casting heat number study, and discloses a double steelmaking tundish continuous casting heat number in-depth study method. The method comprises the following steps that 1) firstly, a reasonable and effective tundish baking system is formulated, the tundish baking time is controlled to be 2 h to 3 h, a capping production mode is adopted on a tundish, and therefore when baking is needed, the casting waiting time is effectively shortened through capping, a cover plate can be pulled to be open when the tundish needs to be stopped, the tundish cooling waiting time and the temperature drop are shortened, and the tundish baking temperature during casting is ensured to be higher than or equal 900 DEG C. By meansof the double steelmaking tundish continuous casting heat number in-depth study method, the double steelmaking tundish continuous casting heat number is wholly and effectively improved, the overall double steelmaking tundish continuous casting heat number in-depth study method is clear and explicit in step, operation is simple, the service life of the tundish can be effectively prolonged, meanwhile, the double steelmaking tundish continuous casting heat number is greater than or equal to 90 furnaces, the production cost of steelmaking is reduced, and implementation by a user is facilitated.

Description

technical field [0001] The invention relates to the technical field of research on the number of ladle continuous casting furnaces in the second steelmaking process, in particular to a method for deepening the research on the number of ladle continuous casting furnaces in the second steelmaking process. Background technique [0002] Steelmaking refers to controlling carbon content, eliminating harmful elements such as P, S, O and N, retaining or increasing beneficial elements such as Si, Mn, Ni and Cr, and adjusting the ratio between elements to obtain the best performance. The pig iron is put into the steelmaking furnace and smelted according to a certain process to obtain steel. The steel products include steel ingots, continuous casting slabs and direct casting into various steel castings, etc. The steel generally refers to rolling into various steel products. Steel belongs to ferrous metal but steel is not completely equal to ferrous metal. The process of steelmaking inc...
