The low creep fireclay refractory brick is an important product in the refractory industry, which has a high demand in industries such as metallurgical, cement, and glass. GB/T 34188-2017 sets the standard for this product, which specifies the classification, technical parameters, and production process.
According to the standard, the low creep fireclay refractory brick is classified into three grades, namely LCFB-1, LCFB-2, and LCFB-3. The LCFB-1 grade has the highest level of performance, followed by LCFB-2 and LCFB-3. Each grade has its own set of technical parameters, such as maximum service temperature, cold crushing strength, and thermal shock resistance.
The production process of low creep fireclay refractory brick involves several steps. Firstly, the raw materials, such as fireclay, kaolin, and other additives, are mixed in a proper proportion. Then, the mixture is homogenized and formed into bricks using a high-pressure molding machine. After molding, the bricks are dried and fired in a kiln at a specific temperature and time to achieve the desired properties.
The low creep fireclay refractory brick has many advantages, such as high refractoriness, low thermal conductivity, and excellent thermal shock resistance. It can withstand high temperature, corrosion, and mechanical stress, making it ideal for use in harsh industrial environments. Furthermore, it has a long service life and low maintenance cost, which helps to reduce the overall production cost.
In conclusion, the low creep fireclay refractory brick plays an important role in the refractory industry. Its various grades, technical parameters, and production process ensure its high-quality performance. As a result, it has a wide range of applications and is highly valued by many industries.
