Abstract

The invention discloses a steel ladle slag layer thickness measuring device and belongs to the technical field of steel metallurgy. The steel ladle slag layer thickness measuring device comprises a rod with a fixed clamping head, the rod clamps a steel bar through the fixed clamping head, and a slag wrapping layer is arranged outside the steel bar. The steel ladle slag layer thickness measuring device is simple in structure and is prepared from waste generated during production so as to achieve waste use and save valuable resources, and a preparation method is low in cost. The steel ladle slag layer thickness measuring device is used for measuring the thickness of slag layers in steel ladles and is simple and feasible in method, accurate in measurement result and low in energy consumption, and aluminum cannot be doped in molten steel. Besides, the steel ladle slag layer thickness measuring device can be reused after measurement procedures are completed, so that production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to a ladle slag layer thickness measuring device, its preparation method and its measuring method. Background technique [0002] With the expansion of the scale of modern industrial production, the requirements for the variety and quality of steel are also increasing. In order to strictly control product quality, quality control in the metallurgical process is particularly important. During the pouring process of the converter, the amount of slag dropped affects the subsequent slagging and refining process. Therefore, it is necessary to have a quantitative value for the amount of slag to guide subsequent production. [0003] The Chinese utility model titled "Metal Liquid Level Slag Thickness Test Probe" with patent No. 97234297.4 discloses a probe for measuring the high temperature metal liquid level and the thickness of the slag layer. The front end...
