Method for quickly and automatically sampling continuous casting tundish

Abstract

The invention discloses a method for quickly and automatically sampling a continuous casting tundish in the technical field of metallurgy, steelmaking and continuous casting, which comprises the following steps of: a static model of a tundish liquid level is established by utilizing continuous casting tundish molten steel weighing and tundish position signals under the condition that continuous casting equipment and an automatic system operate; a specially designed sampling device is guided by interlocking a continuous casting molten steel tank weighing signal and a tundish liquid level staticmodel to accurately, quickly and automatically realize continuous casting tundish molten steel sampling. The automatic sampling method is easy in process control, safe and reliable, and by strictly controlling the sampling time node, the sampling speed and the accuracy, the quality of the taken sample is ensured to have consistency, representativeness, reliability and stability.

Description

technical field [0001] The invention relates to the technical field of metallurgical steelmaking and continuous casting, in particular to a method for rapid automatic sampling of a continuous casting tundish. Background technique [0002] During the sampling process of continuous casting production, operators need to be in close contact with high-temperature liquids. High-temperature radiation and burns and scald accidents occur from time to time. Affected by the sampling environment and the insertion position of sampling personnel, the position and The molten steel flow field is different, and the sampling stability, success rate and sample quality are poor. Contents of the invention [0003] In order to solve the above problems, the present invention provides a static model of the tundish liquid level by using the continuous casting tundish liquid steel weighing and the tundish position signal under the condition that the continuous casting equipment and the automation s...
