The properties of refractory aluminum-magnesium spinel casting materials and their applications in molds are as follows:
Characteristics of refractory Aluminum-Magnesium Spinel Casting Materials
1. High heat resistance: refractory Aluminum-magnesium spinel has a high melting point, and the casting material can withstand the heat of high-temperature molten steel in the pan. It generally maintains a stable state even in high-temperature environments of 1,600°C or more, making it difficult to soften or deform.
2. Corrosion resistance: It can effectively resist chemical attack by steel slag. The low reactivity of the spinel and steel slag components can prevent corrosion of casting materials caused by steel slag and extend their service life.
3. Thermal shock resistance: During use, frequent temperature changes cause thermal stress. Refractory Aluminum-magnesium spinel cast concrete has excellent thermal stability and can withstand thermal shock caused by rapid cooling and heating. It is difficult to crack or peel.
4 • Scratch resistance: When charging, pouring, and stirring molten steel, molten steel and slag damage the vessel lining. Cast concrete has a dense structure and high strength and can resist damage caused by molten steel and slag.
5 • Volumetric stability: Since refractory aluminum-magnesium spinel cast concrete does not undergo significant volumetric changes even at high temperatures, it can maintain the integrity of the fan lining and prevent damage to the lining structure due to volumetric changes. Application of Refractory Aluminum-Magnesium Spinel Casting in Pots
1 • Extends Ladle Life: Excellent performance can effectively reduce damage to the ladle liner, extend ladle life, reduce the frequency of ladle maintenance and replacement, improve production efficiency, and reduce production costs.
2 • Improved Fan Safety: Stable operation ensures the safety of the fan during the molten steel storage and transportation process and reduces the possibility of safety accidents, such as molten steel leakage due to liner damage.
3 • Applicable to Various Steel Grades and Processes: Whether producing ordinary carbon steel, alloy steel, or stainless steel, refractory aluminum-magnesium spinel casting products can adapt to the corresponding temperature and composition of molten steel and meet the diverse requirements of the steelmaking process for fan liners.
4 • Lower refractory consumption: Compared to other refractories, refractory aluminum and magnesium spinel foundries have a long service life and consume less refractory per ton of steel, allowing companies to reduce the cost of purchasing and using refractories.
