Optional firebrick kiln which requires basic conditions

Rotary kiln in the production process, calcination temperature needed to reach thousands of degrees on Baidu or, if it relies on the support calcination kiln shell, will not take long,

cylinder will be burned, in order to protect and calcining kiln shell needs, it is necessary inlay puzzle bricks in the kiln. Brick kiln as a must-have device supporting materials, you need to

have certain properties. Today Henan YuFeng Heavy brick kiln, web series, it says what kind of performance are required: 1, chip resistance. For any of the kiln and kiln stopped and

abnormal operation, kiln temperature will cause dramatic changes. Therefore, refractories must have the necessary thermal shock resistance to resist this change in temperature.

Otherwise, refractories will break. This rupture usually called fragmentation, the horizontal direction of the bricks. 2, chemical resistance (resistance to slag) in the clinker burning process,

the role of the steam produced combustion, ash and slag chemical reaction with firebrick eroded bricks (depending on the type of fuel used). Furthermore, the gas enters the kiln dust

and alkali can also be attached to the firing zone to react with the refractory bricks. Firebrick ability to resist chemical attack became its slag resistance. Do not have this slag resistance,

chemical erosion bricks will be significantly weakened, so that the kiln refractory lining prematurely. 3, wear resistance. Kiln conditions required to be able to withstand the sliding

refractory raw material layer, and the dust mixed in the air stream generated by the friction. Puzzle in the combustion zone before and after the formation of dense skin is usually not the

bricks in each band must have this capability. 4, the ability of the skin linked to the kiln. The highest temperature in the firing zone, fire-resistant material must possess one of the most

important features is the ability to put up a good kiln skin, and can maintain this in a long kiln skin. These four points is to choose the basic requirements of the rotary kiln bricks, kiln used

for other refractory materials, such as castable, fire clay, etc. These also need to have certain conditions, is responsible not achieve the purpose of use. Please indicate Henan YuFeng
