High aluminum brick castable by casting construction, can also be made into refractory prefabricated parts, convenient construction, saving time and labor, the service life is 2 times as much as the refractory brick.

High alumina brick fire castable has a wide range of applications: suitable for heating furnace, soaking furnace, heat treatment furnace, rotary kiln; All kinds of high temperature burner lining, heating furnace water pipe bandaging lining, steel furnace outside refining device components and petrochemical catalytic cracking reactor high temperature wear-resistant lining; Blast-furnace iron channel, cupola iron channel, solid powder gun for hot metal pretreatment, etc. It can also be used to make large prefabricated blocks and furnace linings.

Application: Can be used as a variety of heat treatment furnace lining, such as blast furnace hot blast furnace, heating furnace, electric furnace steel groove

Product description: High alumina brick castable is made of high bauxite clinker as aggregate, fireclay as powder, adding aluminate cement and sodium tripolyphosphate according to the ratio of mixing made of refractory castable.

Product type: The main varieties of high alumina brick refractory castable are Portland cement, ordinary calcium aluminate cement, pure calcium aluminate cement, pure calcium aluminate cement castable, etc. The main varieties of high alumina refractory products hardened by chemical reaction are water glass, aluminum sulfate, phosphate castable and so on.

Main characteristics of high alumina brick refractory castable

1, high alumina brick refractory castable in the low cement content, that is, low calcium oxide content, reducing the material in the production of low melts, thereby improving the product refractories, high temperature strength and slag resistance.

2, the water consumption of stirring is only about half of the ordinary castable, thus improving the compactness of castable and reducing the porosity.

3, after forming and curing, the generated cement hydrate is less, when heating and baking, there is no large amount of water leakage, reducing the medium temperature strength, but as the temperature rises, the material gradually sintering, the strength continues to improve.

4, refractoriness, high aluminum refractory castable refractoriness between 1100 ~ 1700℃.

5, high temperature performance, high strength. Wide operating temperature range. There is basically no shrinkage after high temperature, which overcomes the characteristics of shrinkage of refractory concrete in the past. The products are easy to store, transport and use.

High alumina brick refractory castable is a kind of low cement castable, the cement content is less than 8%. Unlike ordinary refractory castables, most of the calcium aluminate cement in the matrix is replaced by ultrafine powder (Elkem), while adding appropriate additives to meet and exceed the performance of ordinary cement castables.

Production process of high alumina brick refractory castable: material selection -- batching -- stirring -- packing -- storage

1, according to the selection of high aluminum castable raw materials.

2, according to the raw material ** calculation of aggregate, powder grading and binder, additive dosage, requiring strict control of aggregate powder particles.

3. Put the weighed aggregate and powder into the mixer successively and stir evenly, then pour the powder into the aggregate and stir evenly for 8-10 minutes.

4, the stirred high aluminum castable into the ton bag, equipped with additives and bonding agents, and then packaged.

5. The packed high aluminum castable shall be stored in the warehouse, with date marking and moisture-proof and waterproof treatment.
