Alumina Cement Manufacturer

Aluminum cement is a hydraulic cementation material made of high alumina or industrial alumina and calcium carbonate (limestone) in a certain proportion, calcined or electrofused clinker made of calcium aluminate as the main component, alumina content more than 50%, and then ground. The series of refractory cement is usually yellow or brown, but also gray. The main mineral components of alumina cement manufacturing are monocalcium aluminate and other aluminate, and a small amount of dicalcium silicate, etc. It has a high refractory temperature and stability, and is often used as a binder for unshaped refractory materials.

Alumina Cement Application

1. Binder for unshaped refractory materials;

2. Alumina cement manufacturing has high heat resistance, and refractory thick and fine aggregate (such as chromite, etc.) can be made into high temperature resistant (1300 ~ 1400℃) heat resistant concrete;

3. It is used for construction emergency works. Aluminate cement is fast in setting and hardening, and its 1D strength can reach more than 80% of its strength. It is mainly used for emergency projects within construction period, such as national defense, roads, special emergency repair works (leak plugging) and temporary works.

4. High alumina cement is mainly used in sulphate corrosion resistant engineering. It has strong resistance to sulfate corrosion under ordinary hardening conditions, because the cement stone does not contain tricalcium aluminate and calcium hydroxide, and the density is large.

5. This series of refractory cement can also be used in winter construction. Aluminate cement has high hydration heat and concentrated heat release. The heat of hydration released within 1d is 70% ~ 80% of the total amount, which makes the internal temperature of concrete rise higher. Even under -10℃ construction, aluminate cement can set and harden quickly, which can be used for winter construction.

Alumina Cement Advantage

1. It has stable performance, high strength, fast generating strength and strong applicability.

2. Can also be used to prepare refractory castable, prepared low cement refractory castable, light refractory castable, refractory spray coating and other indeterminate refractory materials.

3. High alumina refractory cement can be used to produce precast refractory blocks, slag balls and other shaped refractory materials.

4. Prepare temporary fast construction, rush repair, support concrete, prepare sulfate resistant mortar and other building materials.

This series of refractory castable is made of clay clinker and fine powder as raw material, mixed with micro powder additive and cement as binder, which is used to fill the gap between steel brick of furnace throat and shell and the secondary casting layer of the lower part of water-cooled tube of furnace bottom. It is used in the bottom screed of water cooling pipe or the inner gap of steel brick of furnace throat and the gap between steel brick and furnace shell, and also used in hot air furnace system.

Clay refractory castable series for aggregate with bauxite and flint clay, silica powder, calcium aluminate cement, water reducing agent prepared general castable, choose corresponding grade aggregate, mixture volume density of 2.2 clay castable for customers to use. The refractory product compact structure, high temperature performance is good, good thermal shock resistance and abrasion resistance, construction is convenient, suitable for all kinds of neutral industrial kiln lining.

The clay castable is widely used in a variety of industrial furnaces, the general use temperature of about 1000-1200℃. The aluminum content of clay castable is about 45%. The compressive strength is about 30Mpa. If the thermal shock requirements are high, we must use tertiary clinker for aggregate production, now, there are a lot of waste tertiary brick clay aggregate, aluminum content and refractoriness are no problem, but the thermal shock will be less.

So, buy clay refractory castable cannot listen to price only, price decides quality, not empty at all, take 3 class waste brick and 3 class clinker make castable, the price is about to differ several hundred, and a few customers, listen to price, think that low that clinch a deal, actually this has a lot of quality discretion problem inside. The bulk density of clay castable is different from that of clay-based tight castable. Generally, the bulk density of clay castable is 2.1g/cm3, while that of tight clay-based castable is 2.3g/cm3. This is because the material with other substrates is added in the process of tight clay- based castable, which is more resistant to slag and erosion.

Precautions For Wear Resistant Castable

1. All metal to castable contact surface should be coated with asphalt or wrapped with ceramic fiber paper.

2. The gap of the retractor slot of the retractor brick should be filled with mortar.

3. Mortar joints between all wear resistant firebricks shall be <2.

4. The mortar between each wear-resistant firebrick should be filled, do not leave gaps, otherwise the flue gas will get in when the boiler is running, aggravating the erosion or peeling of the wear-resistant lining.

5. When laying wear resistant bricks, do not cut in principle. If cutting is really needed, each brick cannot be less than 1/2. If it cannot be satisfied, two pieces can be cut at the same time.

6. All the bricks from bottom to top close to push pull each have pull hook, on all support support plate, next brick all should be long shape brick and cooperate to give expand joint, in order to form a whole stable furnace wall body.

7. All mortar joints between bricks shall be coated with refractory resistant mortar, and all bricks shall be laid along the joints. If the corner or end face of bricks is broken, the bricks shall be replaced in case of cracks.

8. When laying bricks, tap them with glue or wooden hammers to make them stick together. Do not use hammers.

9. During the construction of RS high strength wear resisting castable, the amount of water added should be strictly controlled. Generally, the amount of water added should be 6-8. The stirring should be uniform.

10. Wear resistant castable for sale appliances used during construction must be clean and free from contamination, especially chemical contamination.

11. High strength wear resistant castable is formed with applied vibration motor during construction, and vibrates evenly, and the vibrator rod is pulled out slowly during vibration, so as to avoid cavitation of HF high strength wear resistant castable.

12. The wear resistant castable for sale should be checked after demodulation of this series of wear castable. Hammer can be tapped gently. If a clear echo is sent out, it indicates that the castable is relatively dense. At the same time can not appear honeycomb, pockmark. If the honeycomb, pockmarked area is larger, it should be partly chipped out for new construction.

13. After demoulding, the RS high-strength wear-resistant castable lining, which has been inspected and qualified, can be kept warm for 5-7 days before entering the next process.
