Brown Fused Alumina Oxide Manufacturers USA

Lightning arresters are connected at both ends of the transmission line. Lightning arresters use the semiconductor properties of brown fused alumina. When smelting non-abrasive grade silicon carbide, the new method or the sintering method can be used. There is a sudden change in the resistance of the wholesale brown fused alumina valve at a corresponding voltage.

Under normal delivery voltage, the resistance value of the valve plate is very large, and it is almost non-conductive. When the brown aluminum oxide lightning strikes the transmission line, under the high voltage of the lightning, the resistance value of the valve plate becomes very small, so that the black silicon carbide lightning current flows away from the arrester valve plate without entering the electrical appliances and transformers. The deoxidizer is generally a secondary product with SiC ≥90%. 


If it is not removed, it will affect the brown aluminium oxide quality of the steel. This corresponding voltage value is like a valve, so it is called a threshold voltage. Different specifications of silicon carbide valve discs have different threshold voltages, which are suitable for various transmission voltage lines. aluminum oxide abrasive has been used as a steelmaking deoxidizer since the 1960s, and its development has been rapid. In addition to industrial silicon carbide as an abrasive, there are many non-grinding uses. 


The chemical industry uses the chemical stability of white alumina to manufacture various chemical pipes and valves. The carbon material can be anthracite, silicon sand and abrasive Grade black silicon carbide is the same. When non-abrasive grade silicon carbide is produced in large quantities and there is no source of regrind, the full melting method can be adopted, and the aluminum oxide grit bottom and both sides of the furnace are completely filled with new materials for melting.


The black corundum powder is coated on the impeller of the steam (water) turbine by electroplating to improve the wear resistance of the impeller. Ceramic bodies with silicon carbide as the main raw material can be made into effective bullet-proof materials after lining with metal support plates. Because synthetic corundum has excellent high temperature strength and oxidation resistance, it has become the main raw material of high temperature non-oxide ceramics.


Now domestic steel mills also use pink corundum for deoxidation, and foreign countries also import silicon carbide deoxidizers from China. Deoxidizer and refractory silicon carbide processing, without acid and alkali washing and particle size shaping, only requires crushing, emery abrasive particle size requirements are not strict, and the size range is wide. The regrind and spent materials are mixed with new materials and added to the reaction zone.


With the development of the use of refractories and deoxidizers, the selection of raw materials from secondary silicon carbide abrasive has been unable to meet the requirements. In recent years, special smelting has begun. The deoxidizer and refractory silicon carbide manufacturing methods and equipment are the same as abrasive-grade 100 grit aluminum oxide white, but the product purity is low, so the charge recipe is different, and the charge with higher impurities can be used.


When steel is made, there is oxygen in the molten steel. The particle size of green silicon carbide and anthracite is also the same as that of abrasive-grade black silicon carbide. When there are a large number of (abrasive-grade smelted) regrind and spent materials sources, the new material method can be used. The formula of the reaction material is determined according to the ratio of the new brown fused alumina oxide material to the recycled material and the spent material.
