Process for the aluminothermic production of a steel melt |
| 摘要 |
A process for aluminothermic production of molten steel for welding workpieces comprises carrying out the aluminothermic reaction in a crucible of porous or hollow spherical alpha Al2O3 with a density of 0.8-3.0 (preferably 1.0-2.0) g/cm<3> and a bulk density of 0.3-1.8 (preferably 0.4-1.4) g/cm<3>. |
