Description
Magnesia-carbon bricks have high strength, good resistance to mechanical erosion, excellent thermal shock stability, and high refractoriness, making them suitable for use as refractory bricks. This dataset includes major raw materials, auxiliary materials, and energy sources used in the production process; however, infrastructure such as production equipment and factory construction is not included within the system boundary of the dataset. The life cycle inventory is compiled from data obtained from multiple sources. The production process of magnesia-carbon bricks includes raw material procurement, batching and mixing, feeding and mixing, forming, framing and pressing, baking, machining, inspection, and packaging.
Activity Description
The production process of magnesia-carbon bricks includes raw material procurement, batching and mixing, feeding and mixing, forming, framing and pressing, baking, machining, inspection, and packaging.
Process Description
Magnesia-carbon bricks are produced using high-purity high-alumina bauxite, high-purity and high-density fused magnesia, and high-purity graphite as main raw materials, adding appropriate amounts of antioxidants, with phenolic resin as the binder, and formed under high pressure using a 2500-ton fully automatic hydraulic press. The product is used as a working lining material in ladle walls and bottoms, directly contacting molten steel, offering advantages such as high strength, excellent resistance to mechanical abrasion, good thermal shock stability, and high refractoriness.
