    • The present invention is for a method for heating of blanks and other heating of metallic materials in a furnace before working where heat is transferred to a blank in the furnace by radiation. According to the method of the invention an important part of the radiation hits the walls of the furnace and are reflected there before it is transferred to the blank. Preferably the furnace is designed so that head radiation is reflected also at the bottom of the furnace. At least 50% of the radiation which reaches the blank ought to be reflected radiation. The invention is also for a furnace for heating of blanks and other comprising at least one furnace bottom part (1) and at least one furnace top part (4) having side walls (5, 6, 7, 8) where at least parts of the side walls of the top parts are inclined so that opposite walls are inclined towards each other.
    • 本发明涉及一种用于加热坯料的方法以及在加热之前的炉子中金属材料的其它加热方法,其中通过辐射将热量转移到炉中的坯料。 根据本发明的方法,辐射的重要部分撞击炉壁,并在其被转移到坯料之前被反射。 优选地,炉被设计成使得头部辐射也在炉底部被反射。 到达空白的辐射的至少50%应该是反射辐射。 本发明还涉及用于加热坯料和其它的炉子,其包括至少一个炉底部分(1)和至少一个具有侧壁(5,6,7,8)的炉顶部分(4),其中至少部分 顶部的侧壁倾斜,使得相对的壁相对于彼此倾斜。
