Abstract: A method of efficiently melting aluminum and aluminum alloys in a vertical shaft furnace substantially completely by convection is disclosed. The vertical shaft furnace has a generally cylindrical cross-section with a refractory liner and a cast refractory hearth having a concave, generally conical shape. A plurality of downwardly inclined burners are provided in the walls of the furnace arranged in such a way as to prevent the high velocity burner flame from blowing the aluminum material to be melted across the furnace and into burners on the opposite furnace wall.

Abstract translation: 公开了一种基本上完全通过对流在垂直竖炉中有效地熔化铝和铝合金的方法。 垂直竖炉具有大致圆柱形的横截面，其具有耐火衬里和具有凹的大致圆锥形的铸造耐火炉。 多个向下倾斜的燃烧器设置在炉壁中，其布置方式为防止高速燃烧器火焰将铝材料吹过炉子熔化并进入相对炉壁上的燃烧器。
