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
Mullite bricks refer to high-alumina refractories with mullite as the main crystalline phase, and the general alumina content is between 65% ~ 75%. It is mainly used for hot blast furnace top, blast furnace body and bottom, glass melting furnace regenerator, ceramic sintering kiln, petroleum cracking system dead angle furnace lining, etc. Mullite bricks have high refractoriness, up to more than 1790 C, and have good thermal shock resistance. There are two types: sintered mullite bricks and fused mullite bricks. The crystallization of fused mullite is larger than that of sintered mullite, and the thermal shock resistance is better than that of sintered products. Aluminum content: 65-90% Standard brick size: 230*115*65mm Compressive strength at room temperature: 100-120MPa Good thermal shock resistance:
Performance characteristics: wear resistance, corrosion resistance, peeling resistance, low creep, good thermal shock stability, service life is 1.5 times that of ordinary products; Main uses: Mainly used in blast furnaces, hot blast furnaces, carbon roasting furnaces, carbon calciners, coke ovens, steel barrels, casting systems, boilers, cement kilns, glass kilns and various kiln lining and thermal equipment, etc., suitable for metallurgy, machinery, building materials, casting, ceramics, electric power, petroleum, chemical and other industries. Standard size:230*115*65mm First-class high-alumina bricks Al2O3 75% second-class high-alumina bricks Al2O3 60%~75% third-class high-alumina bricks Al2O3 48%~60%
Aluminum content: 25-42% Compressive strength at room temperature: 30-45MPa Standard brick size: 230*115*65mm Cost-effective: The phosphoric acid impregnated products of blast furnace clay bricks with good thermal stability and qualified quality after drying treatment and secondary low temperature firing can be used for masonry of the upper part of the blast furnace furnace lining.

We are specialized in silica refractories for hot repairs of coke oven,glass furnace,which includes fused silica bricks,fused silica precast blocks,fused silica mortar,ceramic welding materials,conventional high duty silica bricks,silica mortar,fused silica ramming mix,gunning mix. Founder of our company is an expert of silica refracories in Sinosteel Refractories for more than 20 years.All the technical staff and control quality control staff are very expereienced,coming from Sinosteel Refractories,too.Passed qualification certification of ISO9001-2008. When the damage to the coke oven is so severe that holes could be observed,brick shaped fused silica precasted blocks have to be adopted to fill the gaps.The fused silica won't display observed thermal expansion,so no heat-up problems. Property of Fused Silica Precast Blocks Zero Expansion,so no heat-up problems Less joints,minimise the leakage of flue gas Save time and Equipment Application:for Hot Repair of Coke Oven,Revamp of Old Coke Battery,Ceramic Welding For further questions,please contact me: Contact: Judy Liu (Marketing&Sales)
Refractory products made of silicon carbide as the main raw material. The content of silicon carbide is 72% to 99%. Generally select black silicon carbide (SiC content more than 96%) as raw material, add binder (or no binder), through batching, mixing, molding and firing and other processes. Silicon carbide brick has high thermal conductivity, good wear resistance, thermal shock resistance and corrosion resistance. So carbonization. Silicon bricks are widely used in industry. It can be used for metallurgical steel tube lining, nozzle, plug head, blast furnace bottom and hearth, heating furnace without water-cooled slide rail, non-ferrous metal smelting distiller, distillation tower tray, electrolytic cell sidewall, smelting metal crucible; shed plate and flame insulation material of silicate industrial kiln; oil and gas generator and organic waste combustion furnace in chemical industry. Aluminum reduction cell lining for high-tech ceramic kiln furniture, molten aluminum conduit and ceramic kiln furniture, lower part of large and medium-sized blast furnace body, hearth and hearth, aluminum refining furnace lining, zinc distillation tank lining, etc.
Features: 1. High refractoriness. 2. Good spalling resistance and wear resistance. 3. Good corrosion resistance. 4. Good thermal shock resistance. 5. High mechanical strength. 6. High-temperature creep rate is low. 7. Good volume stability at high temperature.
The content of magnesium ramming material is above 84%, calcium oxide is controlled at 6%~8%, and ferric oxide is about 6%. Due to its high fire resistance, the service temperature reaches 1850~1950. With the use of superfine powder technology, make the material with high CaO magnesia and ultrafine iron oxide, can fully in the process of calcining synthetic reaction, generating distribution evenly throughout the material 2 calcium ferrite, and no obvious shrinkage phenomenon in the sintering process, ensuring the quality of the material of the sintering synthesis and improve the effect of the use of the material at the same time.After being sintered at 1600â?? for 3 hours, the compressive strength of the sample can reach 40~50MPa, which basically meets the compressive strength indexes required by nickel iron smelting.Therefore, after a certain temperature (not less than 1200â??), the material has high density, high compressive strength, good erosion resistance and volume stability. Magnesium ramming material is used in the bottom of the hot nickel iron furnace. Magnesium ramming material has good heat preservation and insulation property, which can reduce heat loss, improve furnace temperature, shorten smelting time and reduce smelting power consumption.The compactness of the forged furnace lining is good, which solves the local leakage phenomenon caused by the non-compactness of the formed magnesia brick masonry furnace lining. The use of magnesia ramming material to build the nickel-iron furnace has obviously improved the lining life cycle, reduced the consumption of refractory materials, and replaced the shaped materials with amorphous materials, which is over the water.
High alumina firebricks are classified according to the alumina content which is from lowest 48% to highest 95%, manufactured from mineral of bauxite, corundum, etc. By mixing, press-forming, drying, sintering and machining. High alumina bricks feature stable mechanical strength and thermal shock resistance, with high refractoriness of no lower than 1880¡æ, high alumina bricks are commonly used as refractory lining exposed to heat directly or backup insulation linings in various types of industrial kiln or laboratory furnace.

Bricks construction toys is too complicate for the toddlers to play, anyway we suggest maybe both of us should give some helpful stuff to help their complicate imagination in advanced. also here we presents how to make it look simply shapes for toddlers, and also why not parents play together with the babies, help them again and again to break or to interlock, (A college professor now play this as his brainy relax toy ) there is a lot of happy in these cooperations. When you are watching child playing with blocks and play together with him, you will find that the traditional blocks could not match the increase speed of their imagination, their creative ability will be hold back, soon the enthusiasm of creativity will be flow away. 2kgs
