Refractory bricks, also known as refractory fire bricks, are made mainly from silica and alumina. Dense refractory bricks can generally withstand up to 1770 Celsius degrees. Therefore, they are widely utilized in many industrial fields. In China, as the cement industry develops continuously and rapidly, the demand of refractory bricks is increasing fast. Not only refractory bricks buyers, but also manufacturers hope to produce high-quality refractory fire bricks. Thus, how to evaluate the performance of dense refractory bricks becomes a popular topic.

Refractory bricks, also known as refractory fire bricks, are generally made by heating fireclay until it becomes vitrified in part. Dense refractory brick is famous for its ability to withstand high temperature, which is a useful property that can be applied in a variety of fields. Therefore, some people may wonder why refractory fire bricks are able to possess the valuable property of thermal resistant. How are refractory bricks made and what are the ingredients used in the making process?

With the continuous development of some industries in China, people put forward higher requirements for refractory bricks. Therefore, the refractory industry, which has long relied on a wide range of economic growth modes, should intensify its adjustment to meet the needs of the new situation. In the next few years, the prospect of refractory brick industry will continue to expand. At present, brick has a wider range of applications. Only by first understanding it can we better tap its value. So, what is dense brick? How did it perform? In the following article, we briefly introduce this, hoping to help you better understand the dense brick.
