Production requirement of high alumina cement 1, fineness: the finer the cement particles, the larger the surface area, the faster the more full hydration, early and late strength are higher. State regulations: the specific surface area should be more than 300 square meters / kg, otherwise not qualified. 2, setting time: in order to guarantee in the construction have plenty of time to finish the mixing, transportation, molding, and other various process, cement and its initial setting time shoulds not be too short; after the completion of construction, hope cement as soon as possible hardening and strength, therefore the end coagulation time shoulds not be too long. Portland cement at the beginning of the first set of time shall not be earlier than 45 minutes, the final setting time shall not be later than 390 minutes. 3, volume stability: cement paste in the coagulation process of volume change uniformity called the volume stability of cement. If the volume change is not uniform, that is, the volume stability is poor, prone to warping and cracking, reduce the quality of the project and even the accident. 4, refractory cement baking refractory cement lining baking, must pay attention to the following matters: 1) at room temperature 350 degrees, the most likely to cause local burst, to pay special attention to the slow baking. If there are still a lot of steam after the 350 degree heat, still should slow down the speed of heating. 2) in the condition of bad ventilation, water vapor is not easy to discharge, to properly extend the heat preservation time. 3) when using heavy oil for baking, to prevent oil sprayed on the surface of the furnace lining, to prevent local burst. 4) when using wood baking, direct contact with the flame is often caused by local heating too fast, should be protected. 5) to the new cast of refractory cement, at least through the 3D can be carried out after baking. 6) for refractory cement lining should also slow cooling, avoid forced ventilation. High alumina cement application High alumina cement and sulphoaluminate cement refractory cement, equivalent to the cement 625#. Because of its excellent fast setting, high strength, resistance to high temperature characteristics of that day intensity can reach 80% and refractoriness up to 1450 degrees, refractory concrete strength up to 55MPa, is one of the industrial furnace engineering excellent high temperature binder material.

Product Description The durability of Abrasion Resistant Ceramic Lined Pipe and Elbow directly affects the safe running of fluid transmit system! We successfully combined the ceramic with the steel matrix directly, and firstly developed mass production. This technique created a brand-new ceramic-metal bonding way to overcome the problem that the ceramic is lack of impact resistance and thermal stability, and easy to pull off. After times of trials, we insist on choosing 95% Alumina Ceramics with high quality to ensure your best experience. Our new Abrasion Resistant Ceramic Lined Pipe and Elbow have been in service for metallurgy, cement, mining, chemical, thermal power plants for years. Compared to seamless steel pipes and elbow, the uptimes of our tubes used to be prolonged by 10 times. It is the ideal product instead of steel or rubber lined pipe and elbow. Advantages: 1. Good abrasion resistance The liner is High quality wear ceramic with 95% Al2O3 which are sintered under 1700 and the hardness are up to 85HRA which is 271.5 times of manganese steel or 1700 times of chrome steel plate. Special composite method and toughening formula ensure the ceramic not being too fragile to resist the impact of normal blocks. 2. Little loss during running 3. Low project cost Light weight and longer lifetime to save the cost of support structure and handling charges. The charges is similar to basalt piping project, or 20-30% less than wear steel piping project. 4. Good thermal stability -50 ~600 degree C is the ideal temperature. 5. Easy and fast to fix on site Welding, flange, flexible joint are available.
The high alumina heat storage ball is also called a spherical heat storage body, and the spherical heat storage body has the advantages of good thermal shock stability, large heat storage capacity, high strength, easy cleaning, and reusability. Working principle and characteristics of high alumina heat storage ball 1. High alumina heat storage ball is a small ball that divides the airflow into small streams. When the airflow flows through the heat conductor, it forms a strong turbulent flow, effectively breaks the surface layer of the heat conductor surface, and because the ball diameter is very Small, small conduction radius, small thermal resistance, high density, good thermal conductivity, so the requirements of frequent and rapid commutation of the heat-conductive burner can be realized. 2. The heat conductor can be reversed by 20~30 times/h. After the high-temperature smoke flow passes through the bed of the heat conductor, the flue gas can be reduced to about 130 °C. 3. The high temperature gas and air flowing through the heat conductor can be preheated to the same temperature only about 100 ° C lower than the flue gas temperature, and the temperature efficiency is as high as 90% or more. 4. Due to the compact size of the thermal conductor, coupled with the high circulation capacity of the high aluminum heat storage ball bed, even if the resistance increases after the accumulation of ash does not affect the heat exchange index. 5. High alumina heat storage ball has the characteristics of strong oxidation resistance and slag resistance. 6. High alumina heat storage ball replacement and cleaning is very convenient and can be reused. High alumina heat storage ball use: widely used in steel, metallurgical industry heating furnace, alumina melting furnace, forging furnace and other industrial furnaces. It is especially suitable for air storage equipment regenerators and steel furnace blast furnace gas heating furnaces as heat storage fillers. By double preheating the gas and air, the combustion temperature can quickly reach the requirements of steel slab heating. High alumina heat storage ball main specifications: Φ3, 6, 8, 10, 13, 16, 19, 25mm High alumina heat storage ball alumina content: 92% 95% 99 High aluminaheat storage ball packaging: double-layer polyethylene woven bag with a net weight of 25kg, plus tray Win-Ceramic product advantages: high strength, wear resistance, rapid cold resistance, long use time, and cost-effective with imported porcelain balls
