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…
Reverberatory furnace and blast furnace are two key pieces of equipment commonly found in industrial smelting. While similar in appearance, they are fundamentally different systems internally. Understanding their differences can help you better match refractory materials and improve equipment efficiency.…
Reverberatory furnace is an important thermal equipment used in the metallurgical industry for smelting and refining metal materials. It gets its name from the fact that it heats materials by reflecting the heat of the flame through the furnace top…
As a common intermittent industrial kiln, the shuttle kiln is widely used in high-temperature firing processes in industries such as ceramics. It has a high firing temperature and a short firing cycle. Therefore, its refractory lining needs to meet the…
Reverberatory furnaces are crucial thermal equipment in industrial smelting. Their lining materials must withstand high temperatures, chemical corrosion, and mechanical wear. Therefore, the rationality of material selection directly affects the furnace life and production efficiency. This article will analyze the…
In order to test the slag resistance of refractory crucibles of different materials at high temperatures, to understand their corrosion resistance and permeability resistance during use, and to provide a reference for selecting matching refractory materials for smelting kilns. Our…
