The characteristics of firebrick produced by different firebrick manufacturers will be different, and how to quickly distinguish the quality and technology of firebrick is particularly important outside the different raw materials.

An excellent buyer or salesman can identify the good and bad of high aluminum refractory bricks only with more than ten years of "experience", these experiences for the "white" just entered the refractory industry is both a strategic position, but it is difficult to sum up with words. So how in the end to distinguish the quality of a high aluminum firebrick with only the eye? In this issue, the resistant material factory shop will use actual combat experience to discuss with you, "with the eye" to identify the quality of a high aluminum brick.

1. Appearance color and appearance lubrication

See a firebrick, we first see its appearance color and appearance of lubrication, some firebrick quality is not very good when the appearance of lubrication is very poor, the formation of firebrick strength is not good.

The uniformity of the appearance of firebrick color shows that the material is not evenly mixed in the production of firebrick, the uneven distribution of materials will form the uneven distribution of firebrick strength and then reduce the overall strength and service life of firebrick;

2 External impurities

Also is the content of the brick exterior impurities, we often see in the high alumina brick appearance will have some black spots, which is the impurity in the raw material, impurities as little as possible in theory, as a result of these impurities of iron oxide, more simple in the kiln temperature environment is reductive into molten iron, formation of refractory brick structure is damaged, Then it affects the service life of firebrick.

As the use of industrial products, the quality of firebrick directly affects the production safety and production cost of the enterprise, incomplete firebrick will not only bring all kinds of repair strike trouble in production, increase production cost, but also for construction production to increase more not to guess the safety hidden trouble. Visible, quickly identify firebrick quality, find reliable firebrick manufacturer is particularly important.
