Properties of Good Refractory Bricks or Fire Bricks Are Recommended In the Furnace Bio link https://www.123articleonline.com/articles/1278627/properties-of-good-refractory-bricks-or-firebricks-are-recommended-in-the-furnace When it comes to furnaces, fireboxes, and kilns, blocks made up of refractory ceramic materials are used. These blocks are known as fire bricks or alternatively refractory bricks. And they are primarily utilized because they are resistant to high temperatures and have a low thermal conductivity, resulting in greater efficiency. These bricks can easily withstand extremely high temperatures and that without any melting or fusion, which results in them keeping their structure for a longer period of time.
But before one goes and discusses the properties of good refractory bricks, it is vital that they understand different types of refractory bricks present in the market. And while their ultimate purpose is the same, their application varies. Fire bricks or refractory bricks can be distinguished into three categories: basic refractory bricks, acid fire bricks or acid resistant bricks, and neutral refractory bricks. Basic Refractory bricks containing a huge amount of magnesia are favored because of their corrosion and chemical resistance properties. Whereas Acid Resistant bricks, as the name suggests, are acid proof bricks and are utilized to resist acidic reactions from chemicals and even from the weather. An acid proof brick lining of silica is added on natural fire clay to increase the resistance of refractory bricks. Neutral refractory bricks contain the properties of both acid fire bricks and basic refractory bricks; they offer good resistance against the acidic nature of chemicals, environment, as well as against corrosion, but they are not utilized for fire-resistance purposes. Now we come to the properties of good refractory bricks or fire bricks, which are recommended in the furnaces.
