Project Description
| Product Name | MgO Carbon Brick for Electric Arc Furnace |
| Description | Magnesia Carbon brick is resin bonded, made from dead-burned or fused magnesia and graphite under proper temperature, finished after heat treatment. Addition of anti-oxidant such as metal and carbide are often being used to improve its oxidation resistance and high temperature strength. |
| Composition | MAGNESIA, GRAPHITE, ANTIOXIDANTS |
| Features | Ø High Refractoriness, High Wearing Strength Ø High resistance to erosion and corrosion caused by arc temperature and slag contact Ø Excellent in Anti Oxidation |
