Machine-pressed unfired magnesia-carbon composite tundish nozzle for tire cord steel

The invention discloses a machine-pressed unfired magnesia-carbon composite tundish nozzle for tire cord steel, which belongs to the technical field of novel refractory materials with a continuous casting function, and comprises a magnesia-carbon bowl part and a magnesia-carbon body, the magnesia-carbon bowl part takes fused magnesia, graphite, an additive and phenolic resin as raw materials, the magnesium carbon bowl part is prepared from the following raw materials in percentage by weight: 85-92% of fused magnesite, 5-10% of graphite, 1-6% of an additive and 4-8% of phenolic resin, and the magnesium carbon body is prepared from the fused magnesite, fused quartz, graphite, the additive and the phenolic resin. The magnesia carbon body is prepared from the following raw materials in percentage by weight: 60-80% of fused magnesia, 8-20% of fused quartz, 8-20% of graphite, 1-6% of an additive and 5-10% of phenolic resin, proper sintering can be achieved by virtue of heat energy in a use environment, a structure
