Preparation process of prebaked anode carbon block
The invention belongs to the technical field of anode carbon blocks, and particularly relates to a preparation process of a prebaked anode carbon block. Comprising the following steps: crushing, grinding and screening a dry material to obtain aggregate and powder; putting the aggregate and the powder into a mixing and kneading pot for dry mixing, then adding the preheated binder for wet mixing, and obtaining a carbon block raw material after the mixing and kneading temperature requirement is completely met and the mixing and kneading temperature requirement is kept for a certain time; placing the carbon block raw material in a roasting furnace, and fixing the shape of the carbon block raw material by using a mixture of coke powder and quartz sand as a filler to obtain a primary roasted carbon block; putting the primary roasted carbon block into a preheating furnace for preheating, and putting the preheated primary roasted carbon block into an impregnation tank for primary impregnation treatment to obtain a primary impregnated carbon block; and carrying out secondary roasting on the primary impregnated carbon block to obtain the anode carbon block. The preparation process simplifies the process flow, is simple to operate, and improves the stability of the internal structure of the carbon block.
本发明属于阳极炭块的技术领域，具体涉及一种预焙阳极炭块的制备工艺。包括以下步骤：将干料经破碎、磨粉和筛分后得到骨料以及粉料；将骨料和粉料放入混捏锅内干混，之后加入预热后的粘结剂进行湿混，在完全达到混捏温度要求并保持一定时间后，得到炭块生料；将炭块生料置于焙烧炉中，并用焦粉与石英砂的混合料作为填充料，固定炭块生料的形状，得到一次焙烧炭块；将一次焙烧炭块放置预热炉中预热，预热后放入浸渍罐中进行一次浸渍处理，得到一次浸渍炭块；对一次浸渍炭块进行二次焙烧，得到阳极炭块。该制备工艺简化了工艺流程，操作简单，提高了炭块内部结构的稳定性。
