摘要： This invention discloses a high strength magnesium slag brick and a method of producing the same. The high strength magnesium slag brick is composed of 60 to 80 percent by weight of furnace slag from the reduction process of a magnesium production, 15 to 25 percent by weight of crushed stones and/or pebbles, and 1 to 15 percent by weight of gypsum and/or lime. And the amount of water added to the composition is equivalent to 10 to 40 percent of the total weight of raw materials. The method includes dispensing of raw materials, adding of water, mingling, leaving it piled-up, pressing and molding, steam-bathing and drying to obtain the finished product. Gypsum, one of the raw materials of the slag brick, can be produced from the waste gas generated from the magnesium production process. And, the coal cinder or coal ash generated from the burning of coal in the magnesium production process, can also be used as one of the raw materials of the slag brick. This invention uses massive volume of furnace slag from the reduction process of a magnesium production, and together with aforesaid raw materials, to produce construction bricks, easing the environmental pollution problem on one hand, and introducing a new environmental building material on the other hand. The method of producing high strength magnesium slag brick of this invention is simple and is easy to manage. The raw materials are readily available. The production cycle is shorter than conventional processes. The strength of the magnesium slag brick meets the standard of construction brick. And most of all, it is very environmental friendly and economical.
摘要翻译：本发明公开了一种高强度镁渣砖及其制造方法。高强度镁渣砖由镁生产的还原过程中的60〜80重量％的炉渣组成，粉碎的石头和/或鹅卵石为15〜25重量％，石膏为1〜15重量％和/或石灰。添加到组合物中的水量相当于原料总重量的10〜40％。该方法包括分配原料，加入水，混合，堆积，压制成型，蒸汽浴和干燥以获得成品。石膏是渣砖的原料之一，可以由镁生产过程产生的废气生产。而且，在镁生产过程中，由煤炭燃烧产生的煤渣或煤灰也可以作为渣砖的原料之一。本发明使用镁生产还原过程中的大量炉渣，并与上述原料一起生产施工砖，一方面缓解了环境污染问题，另一方面引进了新型环保建筑材料。本发明的高强度镁渣砖的制造方法简单，易于管理。原材料很容易获得。生产周期比传统工艺要短。镁渣砖的强度符合建筑砖标准。最重要的是，这是非常环保和经济的。

摘要： An amount-reduction, harmless, disposal method for heavy metal waste gypsum (HMWG), which belongs to the technical fields of recycling economy and environmental protection. The HMWG used as raw material is subjected to processes of smelting fluxpreparation, lead smelting, fuming, and geopolymeric gelling, to realize amount-reduction, harmless and resources recycling utilization of heavy metal waste gypsum. The smoke containing sulfur dioxide produced in the smelting process is sent to the acid making system, and the produced dust with heavy metal is sent to the dedicated system for heavy mental disposing. The smoke dust produced in the fuming process is returned to the lead smelting system. The secondary HMWG produced in the acid making system would be returned to the preparation process of smelting flux. And the final products would be sulfuric acid and geopolymer material.
