Brown Aluminum Oxide 70 Grit Suppliers China

Attention should be paid to the following points during the process of smelting white alumina using aluminum ash: During the smelting process, black silicon carbide was added to the water, and the temperature was maintained at about 100 ° C due to the reaction between the calcium oxide contained in the water and the water.

Next, the trace metal aluminum contained in the black corundum is oxidized to alumina, and the ammonia gas contained in the aluminum ash is dissolved in water to be removed. The calcium hydroxide generated by the calcium oxide and water reacts with the silicon oxide to form calcium silicate and is attached to the hydroxide. On the calcium surface, the aluminum oxide abrasive volume becomes larger and the density becomes smaller after bonding.


Correspondingly reduced (approximately 6-8h), reducing energy consumption, and because the content of impurity brown fused alumina is reduced, the toughness of the brown fused alumina produced in the end is increased; the aluminum ash filtered by the vacuum filter needs to be dried, so that the free carbon on the aluminum oxide grit surface fully participates in the reaction, and also makes the More evenly distributed.


Then it can be removed by rinsing, pink corundum which reduces the content of silicon oxide and calcium oxide, which not only lowers the temperature during smelting (1700-1800 ℃ can be smelted, by appropriately extending the storage time and adding a stirring operation during storage, the free Carbon escape is more thorough; synthetic corundum which is far lower than the 2000 ℃ requirement for conventional smelting), but also the smelting time. 


At the same time, the free carbon contained in the brown aluminum oxide can escape from the inside of the aluminum ash and adhere to the surface of the aluminum ash by means of the ammonia emission channel after being left for a period of time under the above temperature conditions. During the smelting process, so that the white fused aluminum oxide 60 grit is fully dispersed without agglomeration during smelting.


The silicon carbide abrasive is vacuum-filtered by the aluminum ash After filtering out, it becomes a reducing agent in the smelting process, not only does not need to add carbon during the smelting process, but also reduces the impurity carbon content, preventing the foaming phenomenon caused by the oxidation of free carbon into gas under high temperature conditions; Low temperature emery abrasive smelting using aluminum ash. 


Since the content of silicon oxide in the raw material brown aluminium oxide is reduced, the amount of iron filings added during smelting is also relatively reduced, thereby reducing the amount of iron remaining in the product brown corundum and improving the strength of the brown corundum. Transferred and attached to the surface of aluminum ash as a reducing agent to participate in the reaction, avoiding the introduction of foreign carbon sources.


The experiment proves that the speed of water flow is preferably 3-6m / min. Beneficial effect: Compared with the prior art, the enlargement of green silicon carbide has the following advantages: Because brown corundum is used after the aluminum ash is processed by the above method, the ammonia in the aluminum ash is removed, the equipment is prevented from corrosion, and the free carbon in the brown aluminium oxide manufacturer is made.
