In the steel production industry, the ladle is an essential piece of equipment responsible for transporting molten metal from the steelmaking furnace to the continuous casting machine. Since the service life and stability of the ladle lining are critical, they directly affect production efficiency and longevity. Therefore, ZTM recognizes these vital needs and offers comprehensive…
Fused Magnesia and Large Crystal Fused Magnesia are both high-performance magnesia refractory materials with extensive industrial applications. However, they differ significantly in raw materials, preparation processes, chemical and physical properties, and application fields. 1. Raw Material Sources and Preparation Processes Fused Magnesia Sand: Made from magnesite ore containing more than 47% magnesium, directly melted. This…
When discussing refractory raw materials, customers are most concerned about the material’s durability, stability, and applicability. High Purity Large Crystal Fused Magnesia (LCFM) meets these needs exceptionally well as a high-quality refractory material. 1. High Purity & Chemical Stability LCFM typically contains 97% to 98% magnesium oxide (MgO), maintaining good chemical stability in high-temperature and…
When choosing a Chinese refractory material supplier, customers often need to consider multiple factors, including product quality, stability, and service levels. Selecting the most suitable partner from numerous refractory material suppliers is an important and challenging task. Here are several key points to pay attention to when selecting a Chinese refractory material supplier: 1. Product…
Recently, we faced a challenge: our client planned to mix four different refractory materials in a 20GP container, however, strict requirements from the shipping company regarding the composition of the cargo made this plan difficult. Each container must not contain more than two types of goods, making container consolidation for shipments to the Middle East…
Refractory Characteristics of Calcined Bauxite Calcined bauxite is one of the refractory raw materials, it is sintered after high-temperature treatment, ( Normally sintered it in rotary kilns, round kilns, or shaft kilns at temperatures around 1600°C – 1800°C）， alumina (Al2O3) content ranging from 70% to 90%. The excellent refractory properties of calcined bauxite make it one…
In the steelmaking process, the tundish plays a pivotal role as a crucial refractory vessel. It not only receives molten steel from the ladle but also distributes it to various crystallizers. Due to its unique location and function, selecting the right tundish refractories and ensuring their performance is vital. 1. Functions of Tundish Refractories The…
The main raw materials for magnesia carbon bricks include fused magnesia or sintered magnesia, flake graphite, organic binders, and antioxidants. Magnesia carbon bricks are a crucial component in various high-temperature applications such as electric arc furnaces, converters, and ladles. One of the key factors contributing to their exceptional performance is the selection of raw materials.…
In the early stages of long process steelmaking, the blast furnace is a shaft furnace that burns coke by blowing hot air and reduces iron ore to hot metal. It is a thermal device for the continuous production of iron in a high temperature and reducing atmosphere. Refractory Materials for Blast Furnaces 1.Anhydrous clay Anhydrous…
