In order to guide and standardize the production and operation of magnesia enterprises and promote the balance of market supply and demand, this article mainly analyzes the magnesia market situation in 2024 and predicts the market demand in 2025. Magnesia varieties and applications Light-burned magnesia is the one with the largest downstream demand. It is …
Ladle is one of the equipment required for steelmaking process. With the improvement of converter life, the increase of continuous casting ratio and the progress of refining technology outside the furnace, the ladle is in increasingly harsh conditions of use such as large capacity, multiple steel types, high temperature and long time, and the requirements …
Configuration of refractories for converters In the dismantling of the furnace lining after use, it was found that the damage was caused by the inability to use individual parts of the severe erosion, while many other parts could be used, but had to be discarded in order to build a new lining. Therefore, people put …
The middle bag is an important production equipment in the continuous casting process of steel, the bag age, life length directly affects the yield of continuous casting billet as well as the continuity and stability of the production organization. Extend the service life of continuous casting intermediate package, not only can shorten the operation time …

The converter plays the functions of decarburization, dephosphorization, desulfurization, alloying, heating, removal of inclusions, etc. In smelting, the converter does not need external heat and relies on the exothermic reaction of oxidation in the steel. In the converter, the furnace lining, steel outlet, breathable bricks, etc. are composed of refractory materials. Since its development in …
Medium frequency furnace use process, the thickness of the refractory material used for the furnace lining is only 70-110mm, the inner side of the contact with the high temperature metal liquid, the outer side of the water-cooled coils close to the refractory material inside and outside temperature difference is very large, in the use of …
