Quality differences of fire clay bricks in different area in China

Clay bricks quality is different indifferent area in China due to the local raw materials level, for example of the clay bricks in Henan, the aluminum content is high and more purity, the body is dense, and the use effect is almost the same as the general three-level high aluminum bricks.

Clay brick is one of the lowest grade products in the refractory brick series, but its wide use and low price are the biggest advantages of the product. In China, because of the raw materials of clay bricks, the indicators and use effects of clay bricks produced by provinces are very different. Including the price, there is also a big difference.

The clay bricks produced in Henan have high aluminum content and high volume density due to local raw materials and production processes. The price is relatively higher than that of a clay brick in Shandong and Hebei, and the use effect is also longer than the use cycle in Shandong and Hebei. Henan's clay brick color is yellow and white, the aluminum content is between 52-56%, the single weight of the standard brick is between 3.6-3.65kg, and the ton price is relatively several hundred yuan higher than Shandong and Hebei.

The clay area in Shandong is yellow and red, the aluminum content is about 40-45%, and the single weight of the standard brick is between 3.3-3.5kg, but due to the local material reasons in Shandong, the porosity will be about 3-4% lower than the clay brick in Henan. The sintering temperature is about 30℃ lower than that of clay bricks in Henan area.

The clay brick in Hebei is a deep dark red color, the single weight is between 3.3-3.5kg, the aluminum content is between 40-45%, the single weight of the standard brick is between 3.4-3.5kg, but generally no more than 3.5kg. The difference in sintering temperature and Henan is about 20 °C, the ton price will be 50-100 yuan higher than Shandong brick, and the porosity is higher than Henan and Shandong.

The three places have the lowest ton price of clay bricks in Shandong, the porosity is low, and the ton price of brick in Henan is the highest, but the body density and aluminum content are the highest, and the service cycle is the longest.

The use of clay bricks depends on the actual situation of the use of furnace lining, no matter which region of clay bricks, according to the actual use of selected can not only look at the ton price.
