According to current national standards, the style of refractory brick can be classified into standard shaped brick, normal shaped brick, abnormal shaped brick and special shaped brick.

1. Standard shaped brick: usually the straight brick with the shape size of 230mm x 114mm x 65mm is called standard shaped brick.

A modern glass melting furnace must meet the requirements of high thermal efficiency, low energy consumption, stability of the material rate, good quality of glass, and more than five years of age. This puts forward higher requirements to the storage chamber regenerator which means that the thermal efficiency of the chamber regenerator must be further improved to greatly increase the preheating temperature of combustion air.

Alkaline refractory material refers to that which is easy to react with acid resistant materials, acid slag, acid flux or alumina under the high temperature. Most of the alkaline refractory materials are mainly made of magnesium oxide, calcium oxide and other alkali metal oxides. Alkaline refractory mainly contains magnesite chrome brick, magnesia zirconia brick, magnesia brick, magnesia spinel brick, magnesia calcium brick, dolomite brick and the latest development of magnesium iron spinel brick and so on.

No matter what kind of magnesia brick, different degrees of crack will be produced in the drying process. There are two types of cracks of magnesia brick, one is mechanical crack, and another is non mechanical crack.

Regenerator chamber of glass furnace should select checker brick with high heating unit area which can minimize the heat of checker as far as possible, in addition, must ensure that the heating furnace lining and the checker brick material on the combustible medium has a high anti - erosion effect.

Wear resistance is a mechanical wear ability to resist solid, liquid and dust. In many cases, the damage caused by the mechanical wear of the firebrick surface is often very serious. It is often the direct cause of the working surface loss of a firebrick material. Sometimes, it is more harmful than chemical erosion. For instance, the firebrick liner of superstructure of glass furnace often loss due to lack of wear; the place of air flow scour and melting flow of furnace is also easy to loss due to low wear resistance of firebrick. So, wear resistance of firebrick is an important property.

magnesia brick is one kind of alkali refractory which is generally produced by sintered method. Below is the specific step for your reference.

1. Raw material’s mixing. Match all the raw material of magnesia brick according to reasonable scale, then mix them with wheel mill which can make the mud material with better quality, Because rotation and pressure of wheel mill on the mud have the effect of rolling compaction, pre scheduling and pre compaction.

magnesia brick is an alkali refractory whose main crystal phase is periclase, and the content of MgO is more than 90%. Magnesia brick is made by sintering in high temperature which is through crushing, batching, mixing, molding and sintering at high temperature of 1550 ~ 1600 degrees.

Magnesia brick is the main product of alkali refractories with the good property of slag resistance, superior refractoriness under load, good alkali resistance, strong corrosion resistance and steady volume in high temperature.
