The appearance of the high alumina heat storage ball is spherical, with a diameter ranging from 3 cm to 10 cm. It is composed of high-purity bauxite and other mineral materials and is made by high-temperature sintering technology. High alumina heat storage balls have the characteristics of high specific surface area, bulk density, heat capacity, and thermal conductivity, and can quickly absorb and release heat energy at high temperatures. High alumina heat storage balls are mainly used in solar and geothermal heat storage systems, which can be used to store solar or geothermal energy so as to release heat energy when needed. Solar energy and geothermal energy are two clean, unlimited energy sources, but they both have a common problem, which is instability because they depend on factors such as weather and geological conditions. High alumina heat storage balls can effectively solve this problem, using its excellent heat storage performance, so that energy can be continuously supplied when needed. In addition, high alumina heat storage...

Refractory ball is a kind of ball made of industrial alumina and refractory kaolin through scientific formula, forming, and high-temperature calcination. It is mainly divided into high-alumina refractory balls, silicon refractory balls, magnesium-aluminum refractory balls, porcelain Balls, etc., which are suitable for converters and shift furnaces in the sulfuric acid and fertilizer industries, and high-alumina refractory balls are suitable for hot blast stoves, heating shift furnaces and other equipment in urea, steel, and other industries. The main function of the refractory ball in the actual use process is that it has good high-temperature resistance and high hardness. Putting the refractory ball evenly into the heating furnace can evenly distribute the gas, and the uniformly dispersed gas can reduce the impact on the gas. The role of the catalyst prolongs the service life of the catalyst, and at the same time, it has high hardness, so it can support the heating object in the heating furnace. The working principle of the refractory ball is to divide the airflow into small streams by many small balls. The airflow flows through the heat storage body for a period of time, forming a fierce turbulent flow, which effectively breaks through the boundary layer on...
Lightweight insulation bricks are generally used to keep warm and reduce heat loss, so they generally do not come into direct contact with flames, while refractory bricks can directly contact flames, and sometimes the temperature can reach more than 1,000 degrees, so the two have a great deal of difference. The big difference, today Xinhongji Refractory will give you a brief introduction to the difference between insulation bricks and refractory bricks. 1. Thermal insulation performance The thermal conductivity of general insulation bricks is about 0.2-0.4 (average temperature 350±25°C) w/m.k, while the thermal conductivity of refractory bricks is above 1.0 (average temperature 350±25°C) w/m.k, so you can see The thermal insulation performance of the thermal insulation brick is much better than that of the refractory brick. 2. Refractoriness Generally speaking, the refractoriness of insulation bricks is much lower than that of refractory bricks. Usually, the refractoriness of insulation bricks is below 1400 degrees, while the refractoriness of refractory bricks can reach more than 1500 degrees. 3. Density The density of thermal insulation bricks is generally 0.8-1.0g/cm3, while the density of refractory bricks is basically above 2.0g/cm3, so refractory bricks under the same volume are heavier than thermal insulation bricks. Insulation bricks...
Corundum mullite brick is a material with high performance and high refractoriness, which is widely used in metallurgy, chemical industry, construction, and other fields. Its physical and chemical indicators include volume density, porosity, compressive strength, flexural strength, refractoriness, thermal conductivity, etc. These indicators determine the performance and application effect of the material in different applications. First of all, the bulk density of corundum mullite brick is an important physical and chemical index, usually between 2.2-2.9g/cm³. The lower density indicates that the material has the characteristics of lightweight, lightweight, and large volume, which can reduce the overall load of the building and reduce the self-weight of the structure. In addition, the density directly affects the thermal conductivity and refractory performance of corundum mullite bricks. The lower the density, the smaller the thermal conductivity and the better the refractory performance. Secondly, the opening rate is another important physical and chemical index of corundum mullite bricks, usually between 10-30%. This value directly determines the porosity and airtightness of the material and has a great influence on its thermal insulation performance and fire resistance performance. The larger the porosity, the higher the porosity of the brick body, the lower the density, the smaller the...
How to pour corundum castables during construction actually has certain instructions. We must pour according to the instructions used to prevent secondary rework or damage. Then how do we pour? Next, Xinhongji Refractory will give Let me give you a brief introduction: 1. Stirring of corundum castable The corundum castable can be stirred by a mixer. Usually, we first put the castable into the mixer, stir the dry material for about 2 minutes to make the color uniform, and then add 6-8% of the weight of the castable to stir until the color is uniform. That’s it. It is strictly forbidden to return the material to stir and add water for the second time! 2. Vibration of corundum castable Vibration is used, and the thickness of each layer of pouring should not exceed 400mm. Each construction site should not be vibrated for a long time or be vibrated by hand. It is best to use a plug-in vibrator or a plate vibrator for pouring construction. 3. Maintenance and demoulding of corundum castables The corundum castable can be demoulded 24 hours after pouring, and cannot be watered during curing. Usually, the curing temperature is 5-35°C, and it can be baked after...
