Today, reverberatory furnaces are widely used to melt secondary aluminium scrap for eventual use by die-casting industries. The simplest reverberatory furnace is nothing more than a steel box lined with alumina refractory brick with a flue at one end and a vertically lifting door at the other.
High Alumina Bricks are mainly used to build blast furnace, hot blast stove, top of electric furnace, air furnace, reverberatory furnace and lining of rotary kiln. High Alumina Brick is also can be used as checker bricks of heat accumulating type, chock plug for gating system, nozzle brick and so on.
The magnesia hercynite brick had low thermal conductivity and long service life, and its overall performance was better than magnesia-chrome brick. Magnesia Bricks Features 1.High refractoriness,usually the refractoriness is above 2000°C. 2.Refractoriness under load about 1500-1550°C because of poor high-temperature intensity. 3.Strong ability to resist basic (alkaline) slag,can not contact with acid refractory material. 4.Poor Thermal shock resistance,so keep the temperature of furnace
The construction of the ordinary reverberatory furnace is too well known to need detailed description here. It consists of a vaulted chamber, containing the ore; through this chamber, the flames and products of combustion from a reverberatory furnace and a current of air are made to pass in a horizontal direction above the ore, which is thus heated.
Mainly used for lining of blast furnace, hot blast furnace, electric furnace top, blast furnace, reverberatory furnace and rotary kiln. In addition, high alumina bricks are widely used as open-hearth regenerative lattice bricks, plugs and nozzle bricks for pouring systems.

Sep 24, 2015 · As to the top brick of regenerator, instead of magnesia brick, it can use silica brick, as there is no circulating current in the upper part of the regenerator, so it is reasonable to use silica brick as the superstructure brick of regenerator. Neutral mortar is used to separate the magnesia brick and silica brick.
Basic refractory means refractory made of magnesium oxide and calcium oxide, including magnesite brick, magnesia alumina brick, magnesia chrome brick, dolomite brick, etc. This kind of basic refractory material has the characteristics of high refractoriness and strong alkaline slag resistance and is widely used for open hearth, oxygen converter, electric furnace, non-ferrous metal smelting equipment and other heating equipment.
Dec 05, 2019 · Because a reverberatory furnace is a centuries-old design and has a limited temperature range, it is usually used to smelt non-ferrous, softer metals than iron, such as copper, aluminum, and tin. The furnace design has also been used to smelt nickel and more environmentally-risky metals such as lead, which has given it a negative reputation for the amount of air pollution that it can generate.
In this experiment the cyclone combustor was used to replace the oil combustor in a reverberatory furnace to refine aluminum from aluminum scrap by melting the material at 1000 – 1060°C. For 500 kg aluminum, the oil consumption was 47.5 litre for 2.5 hour or the average was 19 lt/hr and the energy efficiency was 29.2%.
Magnesium Aluminum Spinel Brick for Cement Furnace Application Magnesium alumium spine firebricks main use: First, instead of magnesium chrome sand, magnesium-aluminum spinel brick is used in cement rotary kiln, which not only avoids chrome pollution, but also has good resistance to spalling

Today, reverberatory furnaces are widely used to melt secondary aluminium scrap for eventual use by die-casting industries. [ citation needed ] The simplest reverberatory furnace is nothing more than a steel box lined with alumina refractory brick with a flue at one end and a vertically lifting door at the other.
High aluminum brick has good quality, high refractoriness, long life and other characteristics, is the main use of refractory brick kiln products, commonly used units can not distinguish the quality and grade of high aluminum brick right in the procurement time, caused by the high prices to buy low grade products, thereby reducing the furnace
using two reverberatory furnaces with magnesite or magnesite–chromite direct bond refractories. During the previous decade a quarter of all refractory used in the smelting unit has gone to these furnaces, resulting in above normal refractory consumption per unit production. The factors causing refractory deterioration
Reverberatory Furnace Reverberatory Furnace This is a smelting furnace used in copper production treating either roasted calcine or raw copper sulfide concentrate, which encounters similar type of thermo-mechanical stresses as a flash smelter.
High alumina refractory bricks are mainly used as the lining of blast furnace, hot air stoves, EAF roof, reverberatory furnace, rotary kiln. Furthermore, high alumina refractory bricks are also applied in regenerator of open-hearth furnace as checker bricks, stoppers and nozzle bricks as continuous casting system.
Magnesium aluminum spinel in magnesia alumina spinel refractoryh bricks is a generic name for minerals with the same crystalline structure. Generally, mg-aluminum spinel refractory refers to the general structure of MgAl2O4 or MgO·Al2O3, that is, the magnesium aluminum spinel is prepared from high-purity materials, has good corrosion
