Alumina-Silicon Carbide-Carbon Refractories ASC Working Lining Bricks in Torpedo Car Iron Ladles
Product name, Description, Raw material, Performance & Applications
ASC refractories, short for Alumina-Silicon Carbide-Carbon (Al2O3-SiC-C) refractories, represent a cutting-edge solution for the working lining of torpedo car and iron ladles in the steel industry.
These bricks are meticulously engineered using a premium blend of raw materials, including high-grade bauxite, fused alumina, silicon carbide, graphite, antioxidants, and various additives. Expertly shaped with a phenolic resin binder, they fall under the category of non-burnt carbon composite refractory materials. The production process strictly adheres to dimensional requirements and maintains a strong commitment to high-quality standards.
Our ASC refractories are purpose-designed to excel in the demanding environments of molten metal transportation. They exhibit exceptional attributes such as thermal stability, resistance to alkalis, slag, oxidation, and erosion.
These refractories are primarily used to line hot metal pre-treatment equipment, including torpedo-type mixed iron trucks and iron ladles, during the transfer of molten metal.By choosing our ASC refractory working lining bricks, steel manufacturers can significantly enhance the efficiency and reliability of their torpedo car iron ladles and other metallurgical molten iron pre-treatment equipment.
Chemistry and Physical Properties
The following tables present values for the content of Al2O3, SiC and C elements, bulk density, apparent porosity, cold crushing strength, modulus of rupture, type of bonding, and dimensional tolerance for both of the two types of ASC bricks: Standard and Three-removals.
Standard Type ASC Brick
Three-Removals Type Brick
- Three removals, referring to the removal of impurities such as phosphorus (P), sulfur (S), and silicon (Si) from the molten steel during the steel-making process. Three-Removals type bricks are specially designed to have a higher level of purity and lower impurity content than standard bricks.
Packaging
Here are some reference photos showcasing the packaging of our exporting ASC bricks. The ASC bricks are securely enclosed within robust MDF (Medium Density Fiberboard) wooden pallets or cases, with each package measuring approximately 110x100x75cm and weighing approximately 1 ton.

- Q: How much is one ton of high alumina refractory brick?
- Three high aluminum refractory brick Zhengzhou Kuwait is generally around 800. 32 years of experience, good.
- Q: What are the requirements for Rubble backfill height?
- Backfill should be filled with large stones, big face, small face upward, the decoration is stable, and then use small stones leveling, the gap between the stones can be swept into the slag, gravel, so that the gap filled.
- Q: What are the common thermal insulation materials for thermal conductivity?
- Aerogels are known to be the lightest solid materials in the world. It is made of nanometer silica aerogel as main material and is compounded by special process. The utility model has the advantages of high temperature resistance, low thermal conductivity, small density, high strength, green environment protection, waterproof and non inflammable performance. At the same time, with excellent sound insulation and shock absorption performance, it is now widely used in metallurgy, chemical, national defense, aerospace and other fields, is an indispensable high-performance insulation materials.
- Q: What's the price of high alumina refractory bricks?
- The price of high alumina refractory bricks varies greatly according to the content of AL2O3.
- Q: Aluminum content 38, silicon content 55 What refractory bricks?
- High alumina brick:The mineral composition of the high alumina brick is determined by the bauxite used. The mineral composition of the clinker is usually mullite, corundum and glass. The theoretical composition of mullite is Al2O371.8%, SiO2 28.2%, and its melting decomposition temperature is 1840 DEG C. With acicular crystal, network cross structure, high temperature state showed better strength. Corundum in the form of alpha -Al2O3, melting point of 2050 degrees, hardness of Mohs 9, showing a granular and columnar crystal, has good chemical stability, acid, alkaline slag have a certain resistance. Based on the composition of mullite minerals, the phase composition of high alumina brick can be judged according to the content of Al2O3. When the bricks are below Al2O3 71.8%, the base of the composition is mullite and SiO2, such as grade LZ-48 bricks. Because it contains a large number of SiO2 formed in the liquid phase under high temperature is 20% ~ 30%; brick in Al2O3 more than 71.8%, the excess Al2O3 formed corundum crystal under high temperature, while generating 2 high temperature phase, eutectic temperature rise by the low content of Al2O3 brick 1595 C to 1840 C, such as grade LZ-75 brick. In fact, it is impossible to produce a complete phase equilibrium in the process of production, but the glass phase is very small, and there is no more than 10% in the partial gap of the Yu Jing phase
- Q: What are the specifications for bricks?
- In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.
- Q: Are there any differences between insulating bricks and refractory bricks?
- The insulation performance of thermal conductivity of insulating brick in general 0.2-0.4 (average temperature 350 - 25 DEG C) w/m.k, and the thermal conductivity of refractory brick in 1 (the average temperature of 350 - 25 DEG C) above w/m.k, which can obtain the insulation performance of insulating brick than refractory brick insulation performance is much better.
- Q: What are the requirements for refractory materials in heat treatment furnace?
- Fire resistance is an important performance index of refractory materials, but it does not represent the highest temperature in actual use of refractory materials. In actual use, refractories also bear certain pressure, therefore, must consider the high strength at high temperature refractory material, which is in high temperature under certain pressure without deformation, such as the NZ-40 refractory refractory degree up to 1730 DEG C, but the maximum temperature is only 1350 degrees celsius.
- Q: How to test the aluminium bricks of high alumina refractory bricks?
- Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard
- Q: What is the difference between metal compounds and metal solid solutions?
- Sigma phase belongs to Affirmative system, there are 30 atoms in the unit cell, two element alloy, sigma phase formation is related with the following conditions: (1) the atomic size difference, phase difference between the maximum sigma atomic radius of a tungsten cobalt, the atomic radius difference is 12%. (2) there is a set of cubic lattice elements (coordination number 8), and another component is face centered cubic or dense six square lattice (coordination number is 12). (3) appear in "average number of races" (s+d layer electron number) in the range of 5.7 ~ 7.5. The region of the presence of sigma in the two - element alloy is shown in table 3. In the three element system, the concentration and temperature range of the formation of the sigma phase are affected by the addition of third components. Usually in chromium stainless steel in Fe Cr phase, in Fe - Cr - Mn three yuan, sigma phase iron chromium and chromium can form Mn two element, when the addition of manganese in stainless steel, will promote the formation of sigma phase, and stabilizes the wide temperature range. Many of the Fe Cr alloy elements. The phase temperature range increases. In less than 820C stable Fe Cr phase, silicon promotes the formation of D phase and the stable temperature increased to 900 to 960 DEG C, manganese and molybdenum can improve the temperature stability of sigma phase to 1000 DEG C.
