<p>A method and apparatus for casting steel. The apparatus has a variable lengt h secondary belt conveyor (12) for introducing minute charge materials, a skirted self-positioning charging cart (14) engaging the secondary conveyor (12), a charge conveyor (16) for receiving charge material having a means fo r maintaining a homogeneous scrap bed height that is coupled to the self- positioning cart (14), a dynamic gas seal (18) coupled to both the charge conveyor (16) and a preheater (20), the preheater (20) communicating with th e charge conveyor (16) for preheating the charge material on the charge convey or (16), a connecting car (22) for feeding charge materials into a furnace bath (138) that is removably coupled to the preheater (20) and charge conveyor (16), an electric arc furnace (24) for refining charge therein, an intermediate metallurgical vessel (26) that receives the molten metal discharged from the furnace (24), and a continuous casting device (28) that receives refined-alloyed steel directly from the intermediated metallurgical vessel (26).</p> |
