When it comes to the types of refractory materials, they are basically divided according to the attributes. The attributes are the types below. Let ’s take a look at the types of refractory materials.

1. Acid refractories

2. Alkaline refractories

The temperature that these refractory materials can resist is very high, and the resistance to alkaline slag is very strong. Its main components: magnesium oxide and calcium oxide; the main uses are more for steel-making furnaces, non-ferrous metal smelting furnaces and cement kilns.

3. Aluminum silicate refractories

Refractory materials with silica-alumina as the main component are aluminum silicate refractory materials. Different degrees of alumina, the proportion of 15-30% is semi-silica, the proportion of 30-48% is clay, greater than 48 % Can be called high aluminum, basically these three categories.

There are also several refractory materials, such as cast, neutral, special, and unshaped refractory materials, which are all extended products of the above refractory materials.
