Method for measuring slag thickness and headroom of steel ladle

Abstract

The invention provides a method for measuring the slag thickness and headroom of a steel ladle. The method comprises the following steps of: coating a slag thickness scale by taking the ground of a platform in the rear of a furnace as a carrier and a 0 point as a starting point; coating a headroom scale by taking an upper surface of a sampling hole of the platform in the rear of the furnace and the vertical height of a steel ladle edge as a datum point; inserting the other end of a steel pipe coating with a mark into molten steel vertically, so that the mark of the steel pipe is parallel and level with the upper surface of the sampling hole; and pulling the steel pipe out of the molten steel, and aligning the inserting end of the steel pipe with the starting point of the scale so as to compare the slag thickness and headroom of the steel ladle. By the method, the slag thickness and headroom of the steel ladle can be measured simultaneously in one time without investments, so the method is simple, convenient to operate, time-saving, labor-saving and visual and clear; and the data information of the slag thickness and headroom of the steel ladle can be mastered quickly to adjust loading quantity in time, so the slag blocking success rate of a slag blocking mark of a converter is improved, the tapping slag amount of the converter is reduced, the pollution of slag to the molten steel is reduced, and the yield of smelted alloy is stabilized.

Description

technical field [0001] The invention belongs to the field of detection instruments, and in particular relates to a method for simultaneously measuring the slag thickness and clearance of ladle slag in a steelmaking plant. Background technique [0002] The so-called ladle clearance refers to the height of the steel water surface in the ladle from the upper edge of the ladle. The ladle slag thickness refers to the thickness of the slag in the ladle. After the converter is tapped, it is extremely important and beneficial to accurately grasp the height of the molten steel surface in the ladle from the upper edge of the ladle, that is, the clearance of the ladle, to guide the quantity of the converter loaded, reduce the remaining steel and stabilize the amount of steel tapped from the converter. Accurately grasping the thickness of the slag in the ladle, that is, the slag thickness, is very beneficial and beneficial to reasonably controlling the amount of aluminum added, control...

Problems solved by technology

However, so far, most steel mills have not paid enough attention to the amount of molten steel and slag in the ladle after tapping, and have not even collected or tracked and evaluated the ladle clearance and slag thickness information. , so that the loading capacity of the converter cannot be adjusted in time, and the refining operation cannot be guided, so that a section of the converter after tapping is in an uncontrolled state
