Abstract

In order to solve the problems that a steel ladle is large in weight, short in service life, frequent in maintenance and the like, the invention provides a steel ladle furnace lining which mainly comprises a heat preservation layer, a permanent layer and a working layer which are sequentially distributed from outside to inside. An anchoring part is further fixedly connected to the inner wall of a steel ladle shell, one end of the anchoring part is fixedly connected with the steel ladle, the other end of the anchoring part sequentially penetrates through the heat preservation layer and the permanent layer to be located in the working layer, the heat preservation layer is made of a composite silicate heat preservation material, and the working layer is made of a ceramic fiber high-temperature fireproof coating. The overall structure is light in weight, the heat preservation effect is good, thermal shock resistance is achieved, erosion resistance is achieved, and maintaining is easy.

Description

technical field [0001] The invention relates to the technical field of ladle, in particular to a ladle furnace lining. Background technique [0002] Ladles, also called ladles, are important containers in the metallurgical industry. They play the role of storing and transferring molten steel. At the same time, they also perform the dual task of refining outside the furnace. With the development of steelmaking technology, refractory materials are used in ladles in my country. It has also been well developed. The service life of the ladle is not only related to the consumption of refractory materials, but also directly affects the normal production of steelmaking. [0003] At present, the ladle lining in China is mainly in the state of co-existence of bricks and unshaped refractory materials. In recent years, especially with the improvement of the life of the converter, the increase of the continuous casting ratio and the progress of the refining technology outside the furnace...
