Abstract

The alarm for preventing pouring basket from leaking steel consists of two parts including molten steel conducting element and warning device. Two pieces of molten steel conducting elements are set inside the refractory lining in the shock area of pouring basket working layer and connected via wires to outer warning device or emitter. The present invention has the advantages of simple structure, accurate alarming, etc. and may be used in preventing steel leakage accident.

Description

Technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to an alarm device for preventing steel leakage in a steelmaking and continuous casting tundish. Background technique [0002] Modern metallurgical production has changed the traditional way in the past, and widely adopts the short-process production process of "trinity" of steelmaking-continuous casting-hot delivery and direct rolling. Among them, the continuous casting process is the key process in the production process, and the continuous casting tundish is one of the indispensable important equipments when casting molten steel into billets of various predetermined specifications. Due to the different types of steel poured by continuous casting, different temperatures, and different specifications and shapes of casting slabs, different requirements are put forward for the performance of the tundish. Continuous casting requires its long life. However, because the...
