Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for controlling the quantity of steel passing through the steelmaking crystallizer to deepen the steel index, which has the advantages of ensuring heat transfer efficiency and reducing abnormal wear of the copper tube coating, and solves the problem of continuous casting mold passing through. The amount of steel determines the service life of copper pipes. Increasing the amount of steel passing through copper pipes can reduce production costs, reduce the frequency of crystallizer replacement, increase the maintenance time of package replacement equipment and reduce labor intensity, and maximize the output of steelmaking plants. , to stabilize the steelmaking production organization, there is still room for improvement

Abstract

The present invention relates to the technical field of crystallizers, and discloses a method for controlling the quantity of steel passing through a steelmaking crystallizer to deepen steel indicators, including the following steps: control technology and equipment for cold water quality PH value indicators and electrical conductivity indicators, including water towers, monitoring terminals, and water towers The inside of the water quality monitor is equipped with a water quality monitor, which is in direct contact with the cold water in the water tower and performs real-time monitoring; the cold water quality PH value index control method, the water quality monitor monitors the cold water quality PH value in real time. The steel-making crystallizer flow rate deepens the steel index control method, which has the advantages of ensuring heat transfer efficiency and reducing abnormal wear of the copper tube coating, and solves the problem that the continuous casting crystallizer flow rate determines the service life of the copper tube. The amount of steel passing through the pipe can reduce production costs, reduce the frequency of crystallizer replacement, increase the maintenance time of package replacement equipment and reduce the labor intensity of personnel, maximize the output of steelmaking plants, stabilize the steelmaking production organization, and still have room for improvement question.

Description

technical field [0001] The invention relates to the technical field of crystallizers, in particular to a method for controlling the steel product index of steel-making crystallizer through-flow deepening. Background technique [0002] As the "heart" of the continuous casting machine, the continuous casting mold is an important equipment to ensure the continuous casting production and the stable quality of the slab. With the development and progress of technology, the life of the copper tube of the mold can be improved, which can effectively reduce the consumption of copper tubes Therefore, it is of great significance to carry out the research on the improvement of the steel flow rate of the mold copper tube to stabilize the production and quality, reduce the cost and increase the output of the steelworks. [0003] Chinese patent CN201310104332.X discloses an online operation judgment system for continuous casting machine crystallizers. This method judges online whether the c...
