Electric arc furnace is a key equipment for smelting high-quality steel. It mainly uses electricity to generate high-temperature arc to melt metal scrap. 1.The core working principle of electric arc furnace The core of the working principle of electric arc…
When selecting magnesia-alumina bricks, focus on the three key factors: ingredient ratio, key performance indicators, and compatibility with the intended use scenario. Ensure their high-temperature resistance, thermal shock resistance, and corrosion resistance meet actual requirements. Ⅰ. Screening Key Ingredients and…
In high-temperature industrial scenarios such as steelmaking, cement, and glassmaking, the choice of refractory materials directly affects equipment life and production safety. Different scenarios require different refractory materials due to differences in temperature, medium, and mechanical effects. The following are…
Reverberatory furnaces heat materials by reflecting high-temperature gases and are widely used in metallurgy, chemical engineering, and other fields. The choice of refractory materials directly determines their service life, operational stability, and production efficiency, and is crucial for efficient equipment…
Magnesia-chrome bricks are basic refractory materials composed primarily of periclase and chromite. They are primarily used in critical areas of high-temperature industrial kilns, particularly those exposed to corrosive slag and gases. Core Applications Magnesia-chrome bricks offer excellent resistance to high…
The furnace can be heated to over 1600℃ and still stand steadily, not because of the “stone”, but because of the metallic magnesium hidden in the magnesium bricks. 1.Why does MgO have to be present in magnesia bricks? The skeleton…
1. What is the high-temperature structural strength of refractory materials? High-temperature structural strength is a key performance indicator for refractory materials. It refers to the material’s ability to withstand pressure without deformation under high-temperature conditions. This indicator is typically assessed…
Ⅰ. Identify the Application Scenario and Operating Requirements Operating Temperature: The refractoriness of magnesia-chrome bricks must be higher than the operating temperature. Their refractoriness under load is typically 50-100°C higher than the kiln’s maximum operating temperature to prevent softening and…
When furnace temperatures exceed 1600°C, traditional heavy bricks become bulky and heat-consuming. Alumina bubble bricks, with their lightweight and durable properties, are quietly replacing some high-alumina bricks and corundum bricks as a new choice for furnace linings. 1. First, let’s…
Converter refractory bricks for saleThe key to turning molten iron into molten steel lies in a furnace that can “rotate”. So, what kind of furnace is a converter? This article will introduce you to the true face of the converter…
The reverberatory furnace “swings” the flame toward the material surface. Instead of relying on the flame to penetrate the material directly, the heat is “reflected” back to the molten pool by radiation from the roof. This “discount” makes it take…
The bright moon rises over the sea, and the world shares this moment. As the five-star red flag flutters across China, and as the fragrance of osmanthus blossoms traverses the vast oceans, we celebrate the 76th anniversary of the founding…
