A form of brick that can resist high heat is called firebrick. It is sometimes referred to as firebrick or ceramic brick. The majority of them are Caucasian. Both their heat resistance and compressive strength are good for these bricks. Firebricks’ chemical makeup is distinct from that of regular bricks.
Bricks that can withstand fire have been made using a variety of production techniques. Each fire-resistant brick has been meticulously inspected. I’ll explain how to build refractory bricks today.
An introduction to the manufacturing process for refractory bricks includes the following steps: choosing the raw materials, burning at high temperatures, choosing the grades, crushing and grinding the ingredients, mixing the training and the materials, adhering to strict guidelines, static and boring, and high-temperature firing.
The production and process of high aluminum refractory bricks depends mainly on the nature of the raw materials or the quality requirements of the finished product.
(1) Material preparation. Mainly preparation of high aluminum clinkers and preparation of high aluminum. In the meantime, the preparation of the clinker is to make the refractory high aluminum material and the high temperature burn into granular materials and fine powder at all levels. The preparation of high aluminum is coarsely crushed, boring, finely grinded into powder and mixing.
(2) ingredients, mixed practice and molding. The burning refractory high aluminum clinker is barren material, and it is combined with a certain share of high aluminum to make a mixture. Mixed guessing hits accounted for a lot, called multi -material products. This crystal is high in volume and other properties, but the demand is strong.
(3) Dry. The water content of high aluminum bricks and bricks varies according to the forming method. The water content of semi -dry pressure molding is low. When the water is steaming, it does not shorten the attack. For bricks with more water, you can choose proper natural air -dried or heat heat and heat up in advance, and then send it to the tunnel kiln. The key factors of the boring process control are boring speeds, which should ensure that the brick blank does not deform, does not crack, and has certain intensity as the standard. After all, the water content of the brick in the firing kiln is below 2%.
(4) Burning. The intention of firing is to burn the bricks and make it with a certain strength, fineness, and air hole rate. The intensity of the mechanical strength is high, the volume stability is good, and the refractory performance is good.
