Preparation method of Sirk-Z combined ASC iron runner castable
The invention discloses a preparation method of a Sirk-Z combined ASC iron runner castable, which comprises the following steps: A, premixing: adding a certain amount of Sirk-Z, calcium aluminate cement, soft clay, silicon nitride powder, explosion-proof fiber, alumina micro powder, silicon micro powder and a dispersing agent into a stirring device, and uniformly stirring to obtain a mixed material A; b, aggregate mixing: 15-25 parts of brown fused alumina with the particle size of 0.5-1 mm, 10-20 parts of brown fused alumina with the particle size of 2-5 mm, 10-15 parts of brown fused alumina with the particle size of 6-8 mm, 10-20 parts of white corundum fine powder with the particle size of 0.1-0.5 mm, 10-30 parts of silicon carbide with the particle size of 2-5 mm and 2-6 parts of a carbon material are added into a stirring device and uniformly stirred, and a mixed material B is obtained; compared with the prior art, the problem that the strength of the material is greatly reduced due to medium-temperature dehydration can be effectively avoided, and the material is not easy to burst under the condition of rapid baking.
本发明公开了一种赛克‑Z结合ASC质铁沟浇注料的制备方法，包括以下步骤：A预混合：将一定量的赛克‑Z、铝酸钙水泥、软质黏土、氮化硅粉、防爆纤维、氧化铝微粉、硅微粉和分散剂加入搅拌装置，搅拌均匀得到混合物料A；B骨料混合：将粒径为0.5～1mm的棕刚玉：15～25份、粒径为2～5mm的棕刚玉：10～20份、粒径为6～8mm的棕刚玉：10～15份、粒径为0.1～0.5mm的白刚玉细粉：10～20份、粒径为2～5mm的碳化硅：10～30份和碳素材料：2～6份加入搅拌装置，搅拌均匀得到混合物料B；与现有技术相比，能够有效避免了因中温脱水导致材料强度大幅降低的问题，在快速烘烤情况下不易爆裂。
