The iron in brown corundum was verified by chemical analysis and the Fe2O3 index was reported. In brown corundum, iron exists in an oxide or metallic state and can be magnetic or non-magnetic. Magnet is mainly present in brown corundum in the form of ferrosilicon (FeSi) or ferrous iron, which is a by-product of the 焦炭行业 价格行情 reduction of iron and silica from 焦炭行业 价格行情 bauxite. If the bauxite is low in iron and high in silica, iron is added to the charge to 焦炭行业 价格行情 ensure that the silicon content_div in the ferrosilicon is less than 15%. With an iron content_div of 85%, FeSi is magnetic at room temperature. And can be separated by magnetic separator. The magnetic size of FeSi depends on the temperature and decreases with increasing temperature.焦炭行业 价格行情
If a piece of crystal cracks and passes through a magnetic separator, if it''s still hot, the FeSi''s magnetic properties are reduced and cannot be removed. Black iron or metallic iron is iron worn by crushers and processing equipment and is easily removed by magnetic separators. Non-magnetic iron mainly exists in the form of FeSi or non-magnetic wear-resistant iron. If the proportion of silicon in FeSi is > 15%, FeSi is weakly magnetic or non-magnetic.90%TCCA tablet sample
Non-magnetic wear iron has the same source as black iron, but the source is non-magnetic. Non-magnetic steel is commonly used for crusher parts 焦炭行业 价格行情 conveyor belts and screens. The most common are manganese steel and stainless steel. Fine particles of these steels, and weakly magnetic or non-magnetic ferrosilicon are removed by high-intensity magnetic separators, however, the use of high-intensity magnetic separators results in the removal of large amounts of 焦炭行业 价格行情 acceptable material. The typical process conditions of 焦炭行业 价格行情 Fe2O3 in the brown corundum manufacturer''s brown corundum grade are ≤1.焦炭行业 价格行情 焦炭行业 价格行情 0%, and the refractory grade is ≤1.5%. Iron content_div was determined by standard chemical analysis methods. In addition to chemical analysis, supplemental testing for metallic iron is also recommended.90%TCCA tablet 焦炭行业 价格行情 disinfect
90%TCCA tablet price,Brown corundum used for sandblasting can be refined as a raw material for brown fused alumina for sandblasting abrasives. Sandblasting mill has the characteristics of short grinding time, high efficiency, high efficiency and low price.
The 焦炭行业 价格行情 brown corundum abrasive has a shell-like fracture with sharp corners, which makes the grinding ability better than other abrasives. In particular, it has the advantages of high hardness, large specific gravity, stable chemical properties, and unique self-sharpening. It is the first choice for blasting 焦炭行业 价格行情 abrasives and can also be used for sandblasting and rust removal. The material of the workpiece is sandblasted.
