Application Cases of Refractory Castable C60 in the Metallurgical Industry
The metallurgical industry, including steel, non-ferrous metal smelting, and ferroalloy production, relies heavily on refractory materials to withstand extreme temperatures and harsh chemical environments. Application cases of Refractory Castable C60 in the metallurgical industry showcase its ability to meet the stringent requirements of smelting equipment, ensuring safe and efficient production.
In steelmaking, the tundish is a critical piece of equipment that distributes molten steel and removes inclusions, operating at temperatures above 1600℃. A large steel mill in Hebei Province encountered issues with the tundish lining, where ordinary refractory castables suffered from severe erosion by molten steel and slag, requiring replacement every 30 to 40 heats. This led to frequent production interruptions and increased refractory costs. By applying Refractory Castable C60 to the tundish working layer, the mill achieved a significant improvement: the lining service life was extended to 80 to 100 heats, more than doubling the previous service life. This application case of Refractory Castable C60 is attributed to the material’s high density and excellent resistance to molten steel and slag erosion, which effectively reduced the wear rate of the lining. Additionally, the good fluidity of Refractory Castable C60 allowed for seamless construction, ensuring a smooth and uniform lining surface that minimized steel contamination. This case demonstrates the value of Refractory Castable C60 in improving the efficiency and cost-effectiveness of steelmaking operations. Beyond tundishes, Application Cases of Refractory Castable C60 in steel industry also include the lining of electric arc furnace (EAF) tapholes and ladle walls, which are subjected to extreme temperatures and intense mechanical stress. A steel plant in Liaoning Province adopted Refractory Castable C60 for the taphole lining of its 100t electric arc furnace, where temperatures exceed 1650℃ and the lining is exposed to molten steel erosion and mechanical impact during tapping. Previously, the taphole lining needed to be replaced every 5 to 7 days, causing frequent production pauses. After switching to Refractory Castable C60, the taphole lining service life was extended to 15 to 20 days, significantly reducing maintenance frequency and improving production continuity. This Application Cases of Refractory Castable C60 in steel industry further confirms the material’s superior performance in harsh steelmaking environments, as its high thermal shock resistance and wear resistance effectively withstand the rapid temperature changes and mechanical impact during EAF operations. Moreover, Refractory Castable C60 is also applied in the lining of steel ladles, which are used to transport molten steel from the furnace to the continuous casting machine. A steel mill in Shandong Province used Refractory Castable C60 for the ladle lining, replacing the traditional refractory bricks that required frequent maintenance. The application of Refractory Castable C60 not only simplified the construction process but also extended the ladle service life from 60 to 70 heats to 120 to 130 heats, cutting maintenance costs by 45%. This Application Cases of Refractory Castable C60 in steel industry highlights the material’s ability to adapt to different steelmaking equipment, providing a comprehensive solution for steel plants to optimize their operations and reduce costs.
For non-ferrous metal smelting, such as copper and aluminum smelting, Refractory Castable C60 has also proven to be a reliable solution. A copper smelter in Jiangxi Province used Refractory Castable C60 for the lining of its flash smelting furnace’s reaction shaft and settler, where temperatures reach 1500℃ to 1650℃, and the lining is exposed to corrosive molten slag and flue gases. Prior to using Refractory Castable C60, the lining required replacement every 6 months, resulting in high maintenance costs and production downtime. After switching to Refractory Castable C60, the lining service life was extended to 12 to 15 months, reducing maintenance costs by 35%. This application case of Refractory Castable C60 highlights its superior corrosion resistance against the aggressive media present in non-ferrous smelting, as well as its ability to withstand the high thermal stress generated during the smelting process. The material’s excellent thermal shock resistance prevented cracking and剥落, ensuring the structural integrity of the smelting furnace and enabling continuous production.

Application Cases of Refractory Castable C60 in the Cement Industry
The cement industry is one of the largest consumers of refractory materials, as cement production involves high-temperature processes such as raw material calcination, clinker sintering, and cement grinding. The harsh working environment—characterized by high temperatures, mechanical wear, and chemical erosion from alkali metals and molten clinker—demands refractory materials with superior performance. Application cases of Refractory Castable C60 in the cement industry have proven its effectiveness in key equipment, significantly extending service life and reducing downtime.
One notable application case of Refractory Castable C60 is in the lining of cement kiln transition zones and tertiary air ducts. A large cement plant in Shandong Province was facing frequent lining damage in its 5000t/d cement kiln transition zone, where temperatures reach 1400℃ to 1550℃, and the lining is subjected to severe wear from clinker particles and chemical erosion from alkali vapors. Previously, the plant used ordinary high-alumina castables, which required replacement every 6 to 8 months, leading to high maintenance costs and production interruptions. After switching to Refractory Castable C60, the lining’s service life was extended to 18 to 24 months, a threefold increase. This application case of Refractory Castable C60 not only reduced maintenance frequency but also lowered the plant’s annual refractory material costs by 40%, while ensuring stable kiln operation. The material’s excellent thermal shock resistance prevented cracking caused by temperature fluctuations, and its high wear resistance withstood the impact of clinker flow, confirming its suitability for cement kiln transition zones.
Another application case of Refractory Castable C60 in the cement industry is the lining of preheater cyclones and decomposition furnaces. In cement production, preheater cyclones and decomposition furnaces operate at temperatures between 800℃ and 1200℃, with the lining exposed to alkali metal erosion and material scouring. A cement plant in Henan Province adopted Refractory Castable C60 for the lining of its C5 cyclone and decomposition furnace cone, which are prone to and erosion. The application of Refractory Castable C60 effectively inhibited the formation of alkali-induced, thanks to its dense structure that reduces the penetration of corrosive media. After one year of operation, the lining remained intact, with no signs of or damage, significantly reducing the need for manual cleaning and maintenance. This application case of Refractory Castable C60 highlights its ability to adapt to the complex working conditions of cement preheaters and decomposition furnaces, improving operational efficiency and reducing production losses.
