Rotary kilns are core thermal equipment in industries such as cement, metallurgy, and chemicals. Their interiors are subjected to complex conditions of high temperatures, chemical corrosion, mechanical wear, and thermal shock. Refractory materials, acting as the kiln’s “protective armor,” directly…
In early March, a customer from the Republic of Uzbekistan contacted us. The customer needed 100 tons of magnesium-chromium spray coating for steel ladles. We first communicated and discussed the specifications and specific applications. Subsequently, the customer held a video…
Unshaped refractory materials, also known as bulk refractory materials, are composed of bulk particles and fine powders. They require neither firing nor shaping before use. Their composition and processing can be flexibly modified as needed. For example, the composition and…
1. Characteristics of castable precast blocks Castable precast blocks require only low-temperature heat treatment, making them low-carbon and green refractory materials, and a unique technology in refractory lining. They can improve the performance of refractory linings, reduce refractory material consumption,…
A UAE customer recently consulted us about converter repair. The customer sought our advice on the appropriate refractory materials for converter repair. The Ruitai Lianxin team provided professional solutions and suggestions. Converter repair requires selecting suitable refractory materials based on…
An electric arc furnace (EAF) is an industrial furnace that uses an electric arc generated by electrodes to melt ores and metals at high temperatures. It is one of the core pieces of equipment in the modern metallurgical industry and…
Electric arc furnace steelmaking is a complex high-temperature metallurgical process, with furnace temperatures reaching 1700℃~1800℃. The temperature in the arc zone can even reach 4000℃, while the furnace faces harsh conditions such as slag erosion, rapid heating and cooling, and…
Recently, the converter equipment manufactured by our factory was successfully shipped to Uzbekistan via freight train. This shipment marks the successful expansion of our metallurgical equipment into the Central Asian market and injects Chinese strength into the upgrading of Uzbekistan’s…
A converter is a metallurgical furnace with a rotating body, primarily used for blowing steel or matte. It is the most important steelmaking equipment in the modern steel industry and can also be used for smelting non-ferrous metals such as…
As a core piece of equipment in steelmaking, the converter operates in an extremely harsh environment, enduring high temperatures of 1600-1800℃, erosion by alkaline slag, mechanical impact from molten steel and scrap steel, and frequent sudden temperature changes. The selection…
