Preparation method of novel high-temperature-resistant and high-strength aluminum-magnesium castable
The invention provides a preparation method of a novel high-temperature-resistant and high-strength aluminum-magnesium castable, which comprises the following steps: firstly, premixing silica powder, magnesia fine powder and a dispersing agent in a vibrating ball mill for 20-30 minutes according to a certain proportion, fully mixing the silica powder, the magnesia fine powder and a reinforcing agent, and sealing and storing the mixed fine powder for later use; secondly, premixing the high-aluminum aggregate, the corundum fine powder, the magnesia fine powder, the alumina micro powder, the silica powder and the premix according to a certain proportion in a mixer for 6-8 minutes, and discharging for later use; finally, water is added into a wet mixing machine for stirring, the water adding amount is 5-6%, after stirring, pouring materials are discharged after good fluidity is achieved, the pouring materials are put into a special mold for vibration forming, and various high-temperature-resistant prefabricated parts are formed through pouring; the refractory material has the advantages of low cost, high refractoriness, excellent normal-temperature strength, high-temperature liquid corrosion resistance, high scouring resistance and the like, and can be widely applied to high-temperature containers at the temperature of more than or equal to 1600 DEG C.
本发明提供了一种新型耐高温、高强度铝镁质浇注料的制备方法，包括以下步骤，首先，将硅微粉、镁砂细粉以及分散剂按照一定比例在振动球磨机中预混20~30min，使硅微粉、镁砂细粉以及增强剂充分混合，混好的细粉封存待用；其次，将高铝骨料、刚玉细粉、镁砂细粉、氧化铝微粉、硅微粉以及预混料按照一定比例在混料机中预混6~8min，出料后备用；最后，在湿混机中加水搅拌，加水量5~6%，搅拌后使浇注料得到良好流动性后出料，放入专用模具中振动成型，浇注成各种耐高温预制件；本发明具有成本低、耐火度高、常温强度优异、耐高温液体侵蚀和冲刷能力强等优点，可广泛应使用在温度≥1600℃条件下的高温容器中。
