摘要： The present invention relates to a hot briquetting apparatus for producing reduced iron briquettes comprising a container for receiving high temperature reduced iron; a storage tank connected to and located underneath the container for storing reduced iron and a hot briquetting machine located at a bottom opening of the storage tank. The improvement involves a means for charging residual reduced iron powder, carbon or mixtures thereof as well as an inert gas into the storage tank, said charge means connected to the storage tank and penetrating into the storage tank so that it is attached in a fluid-tight manner; said powder, carbon, inert gas, etc., being funneled into the storage tank in specific proportions in response to control means which are activated by a temperature sensor in contact with the reduced iron within the storage tank.

摘要： A container for conveying a pulverized or granular material includes a bottomed container vessel adapted to be rotated upside down and having an upwardly narrowing tapered section in its upper portion, an opening section formed above the tapered section, and a valve for blocking the flow of pulverized or granular material through the opening section provided within the opening section. The pulverized or granular material can be charged into the container vessel through the opening section while the container vessel is held in a normal upright condition, and the pulverized or granular material can be discharged from the container vessel through the opening section while the container vessel is held upside-down.

摘要： A briquetting machine for shaping a pulverized and/or powder material includes, on the downstream side of briquetting rolls, a pair of notching rolls provided with blades on their peripheral surfaces. The blades extend in the circumferential direction and/or the widthwise direction. The notching rolls are rotated in opposite directions in synchronization with the briquetting rolls, whereby a continuous strip of briquettes discharged from the briquetting rolls can be sheared and separated by the notching rolls. In an alternative embodiment of the present invention, in the aforementioned type of briquetting machine, the interval between the notching rolls is selected such that when the continuous strip of briquettes is bitten between the notching rolls and is not sheared nor separated but it is merely notched by the notching rolls. A briquette guide is disposed on the downstream side of the notching rolls. A divider consisting of a roll and blades mounted radially on the circumference of the roll is disposed on the downstream side of the briquette guide. The divider is rotated in synchronization with the briquetting rolls and notching rolls, whereby webs connecting the briquettes extruded from the notching roll can be separated at the notched positions.
摘要翻译： 用于成形粉碎和/或粉末材料的压块机在压块辊的下游侧包括一对在其外周表面上设有刀片的开槽辊。 叶片在圆周方向和/或宽度方向上延伸。 开槽辊与压块辊同步地沿相反方向旋转，由此从压块辊排出的连续的压块条可以被切口辊剪切和分离。 在本发明的替代实施例中，在上述类型的压块机中，选择切口辊之间的间隔，使得当连续的块状坯料被咬合在开槽辊之间并且不被剪切或分离，但是它仅被切口 通过开槽卷。 在开槽辊的下游侧配置有团块导向件。 由辊和径向安装在辊的圆周上的叶片组成的分隔件设置在压块导向件的下游侧。 分隔件与压块辊和开槽辊同步地旋转，由此连接从开槽辊挤出的团块的网可以在缺口位置分离。
