The invention discloses a production process of stuffing sand. The method comprises the following steps of: (1) adopting recycled waste magnesite-chrome bricks, carrying out primary separation and iron removal, jaw crushing and rough addition into 8mm granules by using a roller machine to remove iron, and then processing into 3mm granules by using a crusher to remove iron, so as to obtain a semi-finished magnesite-chrome sand material; (2) sequentially adding the semi-finished magnesium-chromium sand, quartz sand and an additive into a planetary stirrer according to the technical proportioning requirement, and stirring for 5 minutes to obtain a finished product; and (3) matching and packaging according to the size of customer stuffing sand. The method has the beneficial effects that the waste magnesite-chrome bricks are used as raw materials, the effects of environmental protection and production cost reduction can be achieved, and in addition, the self-opening rate of the ladle filler sand prepared from the magnesite-chrome bricks through the process can be greatly improved.
本发明公开了一种引流砂的生产工艺，包括如下步骤：(1)采用回收利用后废弃镁铬砖，经初选除铁、鄂破、对锟机粗加成8mm颗粒料除铁，然后再经粉碎机加工成3mm颗粒料除铁，即为半成品镁铬砂料。(2)按技术配比要求依次加入半成品镁铬砂、石英砂、添加剂至行星搅拌机内搅拌5分钟即为成品。(3)按客户引流砂大小匹配包装。本发明的有益效果是：通过利用废弃的镁铬砖来充当原料，能达到环保和降低生产成本的作用效果，另外镁铬砖通过上述工艺制成的引流砂，能使其自开率大大提高。
