The advantages of Changxing lightweight insulation brick

Light Weight Mullite Insulation Brick can be widely used as lining or insulation layers of various industrial furnaces and kilns in metallurgical industry, machine building industry, ceramic industry, chemical industry.

These products can directly contact with fire, characterized with high temperature resistance, lightweight, low thermal conductivity and good energy saving effect. nozzle refractory Compared to the traditional "galvanized plate+ insulation cotton" duct, Changxing lightweight insulation brick has the following advantages.
Changxing lightweight insulation brick, using high pure mullite as raw material, is made by adding alumina dry vibration mix powder according to different type and then sintering in high temperature.

1. The energy-saving effects of lightweight insulation brick can be increased by 10% to 15%, having more advantages than the traditional products on energy-saving and insulation aspects
2. Compared to traditional covering agent products, the new lightweight insulation brick’s service life extends three times.
3. When contacting burning fire, lightweight insulation brick is non-smoking and non-toxic gases being released.
4. When lightweight insulation brick used in construction, no condensation water produced, sealing effect is much better.
5. At the same time lightweight insulation brick can reduce 5 to 10 decibels noise.
6. Lightweight firebrick refractory sale insulation brick can shorten project duration 3 to 5 times, reduce 20% project cost
7. Lightweight insulation brick’s output up to 120,000 pieces / day, assure prompt delivery.
8. Manufactured as per ASTM standard

Above all, compared with traditional products, Changxing lightweight insulation brick from insulation effect and environmental protection aspects is more advantageous and it has low cost and strong seal . Applied in smelting furnace, firing kiln, flue, refining apparatus, heating apparatus, reproducing apparatus, gas stoves and pipes, soaking furnace, annealing furnace, reaction chambers, and other similar industrial heat treat equipment.

Introduction of Changxing Refractory self-flow castable

According to the solid theory and the actual service condition of refractory material, Changxing Refractory developed the high-tech self-flow castables after a series of test. Without vibration, self-flow castables can be degassed and leveled by gravity and thereby become compact.

Do you know how the slay ball content influences quality of ceramic fiber paper

The slay ball density is 10 times more than ceramic fiber paper, if the content is too high, it will change the original arrangement structure of the fiber.Ceramic fiber paper’s refractory fiber board density range is 200±20kg/m3. Slay ball’s density range is 2800-3200kg/m3, is 10 times more than ceramic fiber paper. So the content of slay ball directly influences the quality of ceramic fiber paper.The high insulating castable content means lots of crystal grain in ceramic fiber paper, making the flatness and evenness worse. From the surface, some small raised can be seen. The internal fiber bulk’s structure of ceramic fiber paper with good evenness is tight and closed, so the thermal insulation is better. refractory material The internal fiber bulk’s structure of ceramic fiber paper with high slay content becomes worse , holes becomes larger, so making the alumina brick closure property worse, convection heat transfer increases, total heat transfer coefficient increases. All of the above lead to the worse of thermal insulation.The slay ball change the change the original arrangement structure of the fiber, widen the space of fibers, heavily lowering the strength of ceramic fiber paper, once the strength becomes lower, it will leading to the abradability and electrical insulation of ceramic fiber paper worse,refractories reducing the heat insulating ability and utilization rate of ceramic fiber paper.So, we can see it that the amount of slay-removal steps directly influences the slay ball content, then influences the quality of ceramic fiber paper.Changxing ceramic fiber paper is produced by 9 slay-removal steps, the slay ball content is lower than similar products, so the abradability and electrical insulation of ceramic fiber paper is better.

Ceramic fiber module application（2）

Changxing ceramic fiber folded covering agent blanket module adopts Changxing ceramic fiber blanket, folded into accordion-like according to certain width, then embed the anchoring into module and folded and compressed. Changxing modular fiber do not contain any binder. Folded blanket will jam each other in different directions without gaps after the lifting of the strapping. Figure 2 schematic for folding compression module.

     Installation method firebrick refractory sale of Changxing ceramic fiber module in furnace wall, as shown in figure 3. Before module installation, it is need to welding short anchors (head with thread) on furnace wall. And then covered with a layer ladle slide gate of normal Changxing insulation rock wool, thickness 15~20 mm. The module back bead at the center of the hole and short anchor pin alignment, make anchor nail head into the module on the hollow tube, will cooperate with anchor nail head screw nut in a socket wrench head sleeve, insert the socket module of hollow casing, rotate the wrench, tighten nut to anchor nail head. Nut, ceramic fiber felt screw anchor nail and back bead connected in this way, thus the module fixed on the furnace shell.

      Reinforcement ladle castable plate on the back layering is very important, playing the role of reinforcement of bolted joints. Figure 4 shows the shape of after module installation. When the module is installed, folding directions must stagger, Horizontal and vertical module must be installed interval. The aim is to: when all installed, removed the bundle after, let module can free expansion, will fill the gap.

     Changxing refractories ceramic fiber module installation process is simple and convenient, But in strict accordance with the requirements of each step,  Suppose if welding short anchor nail is not secure, will cause the module overall fall off wall collapse and other major accidents, if the direction of module folding did not stagger when installation can lead to a module cannot be subject to uniform pressure and mobility.

Modulation principle of slurry used for refractory brick

Modulation principle of slurry used for refractory brick

Brickwork with refractory slurry should follow the following principles:
    (1) to deal with all kinds of refractory slurry pre experiment and pre laying brick front, confirm the bonding time, different mud initial setting time, consistency and water;
    (2) Modulation of different mud to use different instruments, and timely cleaning;
