Coating thickness scale positioned by utilizing tundish slag blocking wall

Technical Field

The utility model relates to the field of coating construction, in particular to a scale convenient for calibrating the thickness of a tundish coating.

Background

As the last vessel that has passed before the molten steel solidifies, the tundish has an important role in improving the quality of the molten steel. The tundish can remove nonmetallic inclusions in molten steel as far as possible, prevent the molten steel from absorbing air and oxygen in refractory materials, and avoid secondary oxidation so as to meet the quality requirement of clean steel. For some special steel types, the tundish coating material has good forming strength, corrosion resistance and spalling resistance, so that the pollution of refractory materials to molten steel can be reduced, and the cleanliness of the molten steel is improved. The tundish spread is still the best choice for continuous casting of a particular steel grade.

The thickness of the traditional tundish coating is controlled by on-site constructors through experience or other devices such as steel needles, steel scales and the like. And the thickness uniformity of the smearing bag can be found to have great influence on the use of the tundish by detecting the temperature of each part in the process of pouring steel before the tundish and observing after the steel is taken off the tundish. Uneven coating thickness easily causes the work lining weak place to lead to the sintering of permanent lining to cause the difficult and even have the risk of oozing steel of package because of heat gathers. And too thick coating thickness can also cause waste to the resistant material.
