1. High temperature strength; 2. Resistant to corrosion in various atmospheres; 3. Excellent thermal shock stability; 4. Good thermal insulation; 5. The energy-saving effect is remarkable The operating temperature is below 1350C. Thermal insulation refractories are characterized by high porosity, generally 40%-85%; Low bulk density and low dry 1.5g/cm3: low thermal conductivity, generally less than 1.0W (m.K), it acts as the thermal insulation material of industrial kiln, can reduce the heat dissipation loss of the furnace, save energy, and can reduce the quality of the equipment under heat, the mechanical strength, wear resistance and slag erosion resistance of the thermal insulation refractory material is poor, and it is not suitable for the load-bearing structure of the kiln and direct contact with slag, charge, molten metal and other parts

Quartzite Bricks
Magnesia Bricks Description Magnesia Bricks are alkaline refractory materials. These products have over 90% magnesium oxide content and adopt periclase as the principal crystalline phase. Magnesia Bricks can be divided into two categories of Burnt Magnesia Bricks and Chemical Bonded Magnesite Brick. They have excellent performance of superior high temperature mechanical strength and volume stability. Magnesia Bricks can service in the high temperature of 1750.. They are ideal products for glass furnace application. Magnesia Bricks Features: It is a kind of alkaline refractory product with periclase as main phase magnesite-alumina spinel clinker as basic material. the product has such characteristics as good temperature vibration, good strength and volume stability in high temperature. Magnesia Bricks Application Basic open-hearth furnace for steelmaking Electric furnace bottom and wall Permanent lining of oxygen converter Non-ferrous metal metallurgy furnace Hyperthermia tunnel kiln Lining of rotary cement kiln Heating furnace bottom and wall Regenerative chamber of glass furnace Magnesia Bricks Properties High Refractoriness Good alkaline slag erosion resistance High apparent initial softening temperature Good thermal conductivity High thermal expansion Magnesia Bricks Manufacturing Process Burnt Magnesia Bricks are manufactured with magnesite clinker as the raw material and fired in the high temperature of 1550~1600 after smashing, burdening, mulling and molding. High-purity products can be fired in the temperature that over 1750. Chemical bonded magnesite brick is produced with certain chemical bonding through mixing, molding and drying.
High alumina description generally means content of alumina percentage is higher than 45. Alumina is one of the most chemically stable oxides, and it offers excellent hardness, strength and spalling resistance. Alumina refractories are suitable for lining furnace operating up to 1850C. Alumina refractories have the advantages of a high resistance in oxidizing and reducing atmosphere and is extensively used in heat processing industries.

At Gremlog Trading DMCC, we're proud to offer a sustainable alternative for spent refractory bricks. Instead of discarding them, we recycle these bricks into valuable raw materials with various applications. Our recycled refractory bricks can be used in powder coating, road-base aggregate, metallurgical processes, as slag conditioners, and even as feedstock for cement production. This not only reduces waste but also provides cost-effective options for industries. Moreover, these recycled materials can be directly reused in the manufacturing of new refractory bricks, closing the loop on sustainability. Join us in our mission to promote environmental responsibility while meeting your industrial needs. Contact Gremlog Trading DMCC today to learn more about our Recycled Spent Refractory Bricks.
