| titleOfInvention | A kind of manufacture of iron and steel by melting molds new technology |
| abstract | The invention belongs to metal manufacture manufacture field, a kind of manufacture of iron and steel by melting molding new technology is disclosed.The technique is：A) get required raw material ready, pre-processed；Main material is placed in crucible, then crucible is placed in the induction coil of vacuum melting furnace；B) vacuumize, power transmission preheating；C) hoisting power continues to lift up power to 80~100kW, keeps power constant to 60~80KW, 20~30min of power transmission, until furnace charge is completely melt；D) thermometric and temperature control, are filled with argon gas, and sampling detection determines basis；E) refining and Alloying Treatment, sampling detection, determine chemical composition in molten steel；F) power is reduced, when a large amount of conjunctivas occurs in molten steel surface, is had a power failure so that molten steel furnace cooling；Or using ladder solidification；G) it is stripped.The present invention eliminates cast link, obtains high-cleanness, high ingot casting；Present invention process is simple simultaneously, and security is good, and material therefor is with low cost, efficient energy-saving. |
