Silicon steel grade magnesium oxide is a magnesia coating material
used to manufacture oriented silicon steel sheets, and is a high
value-added magnesia product. At present, the United States and Japan
are at the forefront in the research and preparation of silicon steel
grade magnesia. The research on silicon steel magnesia in my country
started relatively late. It was not until 1988 that a production line
with an annual output of 200 tons of silicon steel grade magnesia was
built to replace imported products from Japan. , used in the production
of grain-oriented silicon steel of WISCO. After years of development,
although my country has become a major exporter of magnesium oxide, the
special magnesium oxide industry generally has a small production scale,
unstable product quality, low level of automation and refinement, and
silicon steel grade magnesium oxide is still not self-sufficient. In
2008, domestic enterprises demanded 100,000 tons of silicon steel grade
high-purity magnesia, while domestic production was about 1,000 tons,
which was far from meeting the needs of enterprises.
At present, my country has overcome the technical difficulties of silicon steel production, and large enterprises such as Wuhan Iron and Steel, Baosteel, Anshan Iron and Steel have built new oriented silicon steel production lines. Therefore, the market potential of silicon steel grade magnesium oxide is huge, and it is necessary to strengthen the research on the preparation technology of silicon steel grade magnesium oxide. The name of silicon steel grade magnesium oxide actually indicates its use, that is, magnesium oxide suitable for manufacturing grain-oriented silicon steel sheets. It has special qualities:
