Tracking device for forecasting of slag discharge of continuous casting crystallizer and measuring of tonnage of tundish molten steel

Abstract

The invention relates to a tracking device for forecasting of slag discharge of a continuous casting crystallizer and measuring of tonnage of tundish molten steel. The device comprises a scale, a steel ball and an alarming system, wherein the steel ball floats on the liquid level of molten steel, the lower end of the scale is connected with the steel ball, the scale is movably sheathed with a contact sheet, the upper and lower parts of the scale are respectively provided with an upper conductive metal sheet and a lower conductive metal sheet, the alarming system is electrically connected with the touch sheets via conducting wires, the alarming system comprises an alarming box, an alarming lamp, an alarming buzzer and an alarming switch, the alarming lamp, the alarming buzzer and the alarming switch are arranged on the alarming box, the contact sheets and the alarming lamp are connected by the conducting wires, the alarming lamp, the alarming buzzer and the alarming switch are sequentially and serially connected, and the switch is connected with a power source. The device has the advantages that the interference on the weight of molten steel by the steel slag and covering agent in a tundish is effectively avoided; the production accidents caused by the slag in the tundish flowing into the crystallizer is effectively prevented; the defect of high error of weighing numbers due to accumulation of garbage, dust and the like on a weighing press head is effectively overcome.

Description

technical field [0001] The invention relates to a continuous casting tundish tonnage measuring device, in particular to a continuous casting crystallizer slag prediction and tundish molten steel tonnage measuring device. Background technique [0002] In the normal continuous casting production process, molten steel flows from the ladle into the tundish, and then flows into the crystallizer through the submerged nozzle under the tundish, and is cooled and cast into a slab. Therefore, molten steel has been in dynamic changes in the tundish. Stable control of the tonnage of the tundish is an important indicator in continuous casting production. The amount of steel flowing into the tundish from the ladle must match the amount of steel flowing into the mold from the tundish to keep the tonnage of the tundish stable and ensure continuous casting Constant pulling speed and stable production. If the steel flow of the ladle into the tundish is greater than the steel flow of the tun...

AI Technical Summary

Problems solved by technology

[0005] 1. There is a hidden danger of slag in the mold when the final pouring or replacement of the tundish 3: due to the influence of the covering agent and steel slag 4 in the tundish on the weight, the weighing data and actual tonnage of the final pouring molten steel in the tundish 3 are distorted, and the molten steel is judged from the weight data Whether the casting is completed, the covering agent and steel slag 4 in the tundish 3 are regarded as the weight of molten steel, and there is a risk of slag falling into the mold

[0006] 2. Prone to failure or high error:

[0007] The continuous casting production site environment is complex, and the weighing head 7 often accumulates garbage, dust, etc., resulting in high weighing digital errors

Due to many factors affecting the weighing method, including: foreign matter interferes with the weighing head 7, abnormal flow of slag into the ladle in the tundish 3, etc., the weighing value does not truly reflect the weight of the molten steel in the tundish, and at the same time, it is prone to failure and high error defects Therefore, there is a risk of production accidents
