The ferrochrome industry has fast development in recent years, large material demand and wide market prospect, but the production process and equipment of ferrochrome are relatively backward. The ferrochrome is produced by adopting a small smelting process, and the lining material of the ladle for the process always adopts a composite structure formed by clay bricks, high-alumina bricks and common low-cement castable or steel fiber reinforced refractory castable, and the structure has the defects of low temperature resistance, poor thermal shock stability and short service life. Along with the increase of national energy conservation and emission reduction, the small smelting process is gradually eliminated, and a large kiln is used instead, so that the original process is not suitable for the use requirement, and under the background, the production of a large-scale casting ferrochrome ladle is needed to improve various index performances and meet the production requirement and market requirement.
The low-carbon and micro-carbon ferrochrome is produced by a heat exchange method at present, the temperature of an electric furnace is about 1650 ℃, the temperature of molten iron flowing into a ladle from an ore-smelting furnace is about 1600 ℃, the use temperature is relatively high, and more slag is produced, so that a slag layer adhered to the surface of the ladle is thick; therefore, when the ladle is put into use after the slag layer in the ladle is cleaned every time, the ladle is subjected to quenching and rapid heating thermal shock, and is also subjected to mechanical damage caused by a hooking machine during ladle cleaning, and the severe service environment seriously influences the service life of the ladle refractory material. The existing ladle uses high-aluminum low-cement castable, the service life of the castable on the ferrochrome ladle is about 70 furnaces, the service life is lower, the production rhythm of a steel mill and the normal operation of the ladle are affected, and the service life of the ferrochrome ladle is urgently required to be improved by improving the performance of the lining castable. Under the condition, the applicant develops andalusite-based self-flow castable which has high strength, good thermal shock stability and flushing resistance and can be well adapted to the use environment of an alloy ladle.
In addition, in the preparation process of andalusite-based self-flow castable for ferrochrome ladles, after the processes of proportioning and stirring are completed, the base material and the auxiliary material of the castable are required to be packaged separately. However, when the bag of base material is used, auxiliary materials with specific proportion are needed, and when the bag of base material is used, the auxiliary materials are temporarily proportioned, so that the operation is complex due to difficult weighing, and the problem of inconvenient subsequent use on a construction site occurs; transporting separately also further increases transport and scheduling costs.
In view of the above, the applicant provides a andalusite-based gravity flow castable for ferrochrome ladles and a preparation process thereof, which can remarkably improve the use strength and thermal shock stability when used as a ferrochrome ladle lining material; in addition, the corresponding preparation process and the automatic packaging equipment involved in the process packaging step are developed in a matched mode, the base materials and the auxiliary materials can be respectively and automatically packaged, the base materials and the auxiliary materials are matched and packaged together, and the production efficiency is improved, and meanwhile follow-up use is convenient.
