Brown Fused Alumina BFA Grade A Manufaturer Spain

Of course, the damage to open hearth masonry is mainly caused by chemical erosion of molten slag and molten steel and high-temperature erosion or spalling(silicon carbide abrasive). The top of the open hearth furnace is the most vulnerable, and it is the weak link of the entire furnace lining, which is directly related to the production half of the furnace(180 grit aluminum oxide blasting media). The so-called open hearth furnace age refers to the furnace top life.

With the development of enhanced oxygen blowing in open furnaces, the production efficiency has increased significantly, but the age of the furnace has decreased(green silicon carbide). The bracket is fixed on the base. The key to its manufacture is the use of high-purity raw materials, high-pressure molding and high-temperature firing(aluminum oxide abrasive blasting grit). Therefore, all countries regard furnace top life as an important technical index of open hearth furnaces.(brown fused alumina bfa grade a manufaturer spain)


Most flats in the United States use chemically combined non-burned magnesia-chromium bricks(brown fused alumina), and Europe generally uses fired magnesia-chromium bricks; Japan uses iron skins to wrap the non-burnt magnesia-chromium bricks as the roof. Magnesite spinel brick is used as the furnace roof(aluminum oxide abrasive media); magnesium aluminum brick is commonly used in China, so that the life of the medium-sized open hearth furnace roof reaches about 1000 times.


(brown fused alumina bfa grade a manufaturer spain)As the firing temperature increases(brown aluminum oxide), the flexural strength of the directly combined magnesia-chrome bricks increases significantly, but the strength of the magnesia bricks decreases to 1800 ° C. During installation, the temperature difference along the height of the electric furnace must be considered to be the smallest(emery abrasive). In the 1960s, alkaline bricks were widely used in open hearths in countries around the world. 


Most of the liquid materials (synthetic resins, varnishes, paints, glue and rubber solutions, water glass, etc.) used in the production of abrasive tools(brown aluminium oxide), the viscosity of which is largely a parameter that determines their quality and composition. For this reason, it is necessary to improve the quality of bricks and develop new varieties to meet the needs of open hearth smelting process(synthetic corundum), in order to more accurately measure the viscosity of the melt or liquid.


Sometimes it is necessary to check the viscosity of the melt (when melting the abrasive). When the falling ball continues to fall(white aluminium oxide), the lower radiation source is blocked, the relay 8 is activated, and the time measurement system is stopped. An electric furnace (preferably laboratory type) is also installed on the base(aluminum oxide grit). Under such circumstances, the United Kingdom successfully developed self-joining basic bricks in 1959.(brown fused alumina bfa grade a manufaturer spain)


It should be noted that when measuring the viscosity of liquids in the abrasives industry(black aluminum oxide), the measurement values of the B3-1 and B3-4 viscometers are basically used as standard units. These viscometers or other similar viscometers have a serious disadvantage, that is, it is difficult to use them for continuous measurement(aluminum oxide abrasive), and continuous measurement is necessary in certain processes (such as when producing emery cloth sandpaper).


(brown fused alumina bfa grade a manufaturer spain)Flow method, falling body method, torque method, vibration method, ultrasonic method, etc(pink aluminum oxide). The Soviet industrial department designed a variety of viscometers based on the above principles, which can be used for both production and scientific research(black silicon carbide). The working principle of the falling ball viscometer is based on Stokes' law, that is, the viscosity of the liquid is related to the falling speed of the solid in the liquid.
