Requirement for fireclay bricks acceptance

Acceptance of fireclay bricks masonry of refractory brick works, to carefully check the flue gas in the furnace at, in, particular attention should be paid to the single arch, vault, and the bottom of the equipment. Then I will give you detailed introduction:

1, in the building when the fire clay brick, refractory and mud, labeling, etc., composition and levels are required to comply with the specifications and drawings;

2, to ensure the quality of construction fire clay brick is good, also is to follow the wrong sewing, levelness and verticality, mortar joint thickness and size and drawings in accordance with standards;

3, in the process of acceptance of the furnace body, assigned for the shop assistant director must come from above, each part of the furnace body check, made several mortar joint thickness inspection, furnace body parts measured by the size of the acceptance certificate of admission, careful examination of many important structure of the furnace body. The building block.

The above is to introduce you to the acceptance of clay firebrick, for reference purposes only, hope to help you, if you need to purchase, please contact us!”http://www.chinafirebrick.com”

Main factors affecting the service life of the refractory bricks

According to the long-term use of refractory bricks and refractory brick life mainly includes the influence of the specific use of the environment, the operating temperature of refractory brick
kiln, the use of the number of fly ash erosion. The principle of damage of refractory brick includes three aspects, the solubility, permeability, cinder of refractory brick erosion, friction. These three processes and ultimately affect the service life of the refractory brick, firebrick damage caused by.

Slag brick permeability leads to uneven texture, when encountered high temperature refractory bricks, due to uneven texture, resulting in heat coefficient is not the same, cracking caused by refractory brick. According to the summary of practical application, start and stop times increase the erosion of furnace firebrick, so the reasonable control of furnace of the open stop times can prolong the service life of refractory bricks.

Effect of fly ash on properties of  refractory brick is relatively large, very permeable brick composition of fly ash is silica, a relatively high calcium oxide, if these two components in coal ash, so the erosion of refractory brick is very large, a reasonable construction of the two components can reduce the erosion of refractory bricks to improve refractory brick service life.
