Problems solved by technology

[0002] In the process of promoting high-efficiency continuous casting production, iron and steel enterprises attach great importance to the quality control of continuous casting slabs. It is necessary to pay continuous attention to the actual changes in the liquid level of the tundish during the pouring process. The floating of objects and the prevention of slag entrainment are very important. Some production plants realize the indirect understanding of the liquid steel level through tundish weighing. The accuracy of the weight is extremely poor, which can easily lead to monitoring errors and production quality accidents

specific Embodiment

[0015] A method for observing the height of a tundish liquid level, comprising the following steps:

[0016] 1. Set the marked refractory slat. After the tundish working layer (such as dry material) is finished baking, when the tundish is installed with the stabilizer, install the slat synchronously. When installing the slat, use a special T-shaped steel bar (the length direction is placed on the upper mouth of the tundish steel shell, and the specific position of the short direction steel bar coincides with the specific position of the slat, so as to calibrate the height position of the specific position of the slat from the upper mouth of the tundish;

[0017] 2. During the ladle pouring process, the immersion of the ladle long nozzle and the position of the intersection of the tundish liquid level and the marked slats are observed through the ladle ladle flow hole (inlet) reserved on the tundish, so as to judge the middle The position (data) of the liquid level in the ladle...

Abstract

The invention belongs to the field of continuous casting steel ladle casting, and relates to a method for observing the liquid level height of a tundish, which is characterized in that a refractory material batten with a special mark is arranged on the inner wall of the rear wall of the tundish, which can be observed by a tundish cover steel ladle steel flow hole, and a steel ladle casting worker observes the intersection of the liquid level of the tundish and the specific mark of the batten to obtain the liquid level height of the tundish. The position of the liquid level on the batten is judged, so that the distance between the liquid level and the upper opening of the tundish is known; by monitoring the liquid level height of the tundish, the probability of quality problems such as pouring accidents and slag entrapment caused by misjudgment of the liquid level height of the tundish can be reduced.

Description

technical field [0001] The invention belongs to the field of continuous casting ladle casting, and relates to a method for observing the liquid level height of a tundish. Background technique [0002] In the process of promoting high-efficiency continuous casting production, iron and steel enterprises attach great importance to the quality control of continuous casting billets. It is necessary to continuously pay attention to the actual change of the liquid level of the tundish during the pouring process. A stable liquid level is necessary to control the inclusions in the tundish. Floating and preventing slag rolling are very important. Some production plants can indirectly understand the height of the molten steel through the weighing of the tundish. The weighing accuracy of the tundish requires extremely high structural design, use and maintenance of the tundish truck. The accuracy of the weight is extremely poor, which can easily lead to monitoring errors and lead to prod...
