Alkaline Series of Firebricks Classification


Alkaline refractory bricks are refractory products that contain alkaline oxides such as MgO and CaO as their main components. The main types are the following.

1.Magnesia refractory bricks, refers to the magnesia as raw material to the main crystalline phase of periclase, the content of MgO style in 80% ~ 85% more refractory brick. Its products are divided into two major categories of metallurgical magnesia and magnesia products. Depending on the chemical composition and use, there are Martin Sand, ordinary metallurgy magnesia, ordinary magnesia, magnesia-silica brick, magnesia-alumina brick, magnesia-calcium brick, magnesia-carbon brick and other varieties. Magnesia refractory bricks is the most important alkaline refractory products, high refractoriness, good resistance to alkaline slag and iron slag, is an important advanced refractory bricks. Mainly used in open hearth, oxygen converter, electric furnace and non-ferrous metal smelting.

2.Dolomite brick, is a dolomite as the main raw material to produce a alkaline refractory brick. Mainly used in open hearth furnace regenerator, ingot brick, heating furnace and copper smelting furnace also has good effect.

3.Forsterite refractory bricks, is based on forsterite 2MgO · SiO2 as a main component of a refractory brick. Mainly used for hearth regenerator lattice brick, ingot brick, furnace bottom and in the copper smelting furnace also has good effect.
