Roasting process for roasting special graphite with superfine structure in open-type ring-type roasting furnace
The invention belongs to the field of special graphite roasting, and provides a roasting process for roasting superfine-structure special graphite in an open-type ring roaster, which comprises the following steps of: loading a graphite blank into a material box; mounting a fire frame and a flue frame; an induced draft fan is started, and fuel is ignited; gradually raising the temperature according to a roasting curve, intermittently changing the notch direction of a baffling assembly in a preheating stage and a temperature raising stage, and opening all middle baffles in a heat preservation stage; and after roasting is finished, taking out the graphite blank. By arranging the baffling assemblies capable of changing the notch directions, after the notch directions of the baffling assemblies are changed, the flowing paths of flue gas are opposite, in the preheating stage and the high-temperature sintering stage, the two baffling assemblies are alternately used, the upstream and downstream of the flue gas are intermittently changed, and therefore the temperature distribution of the side wall of the flame path can be more uniform, and the combustion efficiency is improved. And the flame path is rapidly heated, so that the quality of the graphite blank is ensured.
本发明属于特种石墨焙烧领域，提供了敞开式环式焙烧炉焙烧超细结构特种石墨的焙烧工艺，包括将石墨坯料装入料箱内；安装火架和烟道架；启动引风机以及点燃燃料；按照焙烧曲线逐步升温，在预热阶段以及升温阶段，间歇改变折流组件的缺口方向，在保温阶段，打开所有的中间挡板；焙烧结束后，取出石墨坯料。本发明通过设置可改变缺口方向的折流组件，在改变折流组件的缺口方向后，烟气的流动路线为之相反，在预热以及高温烧结阶段，交替使用两种折流组件的形态，使烟气的上下游间歇改变，从而可以使火道侧壁的温度分布更均匀，并使火道快速升温，保证了石墨坯料的质量。
