What are the places where refractory Sk32 Fire Brick is easily damaged in the production process? Today, we will lead you to explore the weaknesses of refractory Sk32 Fire Brick so that we can make better use of them;
Refractory Sk32 Fire Brick is an indispensable high temperature resistant material in smelting production. However, different damage phenomena will occur in the production and use of clay bricks. In the production process, cracks are one of the most prominent types of refractory Sk32 Fire Brick. In particular, the scrap rate of cracked bricks for smelting remains high. The quality of thermally conductive products is unstable and fluctuates greatly. adversely affect normal production.
Shadow of Mud:
1. The mud is too fine: During the crushing process of the mud, due to various reasons, the particles of the clay clinker are small. In the process of pressing, the air in the blank is not easy to be discharged, and the elastic after-effect produced after being pressed is large, and cracks are prone to occur.
2. Excessive water content: When the mud is mixed, the grinding head cannot grasp the water content. When the water content is too large, the material loaded into the mold cavity according to a certain amount will thicken the water film on the surface of the particles, which will affect the close contact of the particles. During molding, the pressure gradually increases, and the elastic expansion of water gradually increases, and it is easy to concentrate in the non-dense places, resulting in cracks on the surface of the brick.
Effects of suppression:
1. Improper method: In the process of molding, the molding operator is not first light and then heavy, slow like pressing, but first heavy and then light, and pressing rapidly. The gas inside the brick cannot be discharged naturally with the increase of pressure. The bulk material is suddenly affected by gravity, and the gas is rapidly concentrated to a certain part, which has a destructive effect on its surface, resulting in the appearance of cracks.
2. Excessive pressure: Since the operator’s technique is not too hard, the material is formed densely to a certain degree during the pressing process, and the brick continues to be pressurized. At this time, the relationship between pressure and compression is insufficient and proportionally increased, and the material begins to be brittle and elastic deformation. . When the pressure greatly exceeds the critical pressure, the reaction force generated after the green body is stressed will play a negative role, and over-embossing will occur.
First of all, let’s look at the advantages of refractory Sk32 Fire Brick.
The first point is that this clay brick is very environmentally friendly. It belongs to the category of recyclable resources, so we can use this clay brick with confidence and boldness. It is not harmful to our health.
The second point is that this refractory Sk32 Fire Brick can have good fire protection and heat insulation effects, but the used refractory clay brick can be used as concrete, which can be said to save a lot of resources.
The third point is that the price of this refractory Sk32 Fire Brick is not as expensive as other bricks. Take the lightweight brick as an example, its price is relatively expensive, and the price of this clay brick is very high. It’s cheap and very durable.
Fourth, it also has a good moisture-proof function. Even if it is a bungalow, we don’t have to worry about the phenomenon of water leakage when it rains.
Next, let’s take a look at the disadvantages of clay bricks.
The first point is that this refractory Sk32 Fire Brick is made of concrete mixture, so its weight is mainly larger than that of other wall masonry materials, so it will make the whole building bear more weight. The cost of the entire project has increased.
The second point is that its sound insulation effect is worse than other products. Its sound is transmitted into the refractory Sk32 Fire Brick. Because there are not many gaps in its space, it cannot well isolate the sound. The third point is that it is very damaging to the environment, because it is made of concrete and needs to use soil. When digging soil, it may damage some trees, which can easily cause soil and water loss. For this reason, our country is now slow. Slow start banning refractory Sk32 Fire Brick.
