More Information
Summary:The invention belongs to the technical field of riser material preparation and particularly relates to a graded oxygen supply and staged heating high heating thermal insulation riser material which isprepared from the following raw materials in parts by weight: 2-10 parts of hollow microsphere, 30-40 parts of mullite, 24-28 parts of aluminum powder, 8-10 parts of CuO and 5-12 parts of MgO. The graded oxygen supply and staged heating high heating thermal insulation riser material is low in initiation temperature and is good in heating effect and thermal insulation effect as the solidificationtime of a metal liquid in the riser material is long. 本发明属于冒口材料制作技术领域，具体涉及种分级供氧分阶段发热高发热冒口材料，由以下重量份数的原料组成：空心微珠2-10份、莫来石30-40份、铝粉24-28份、CuO 8-10份、MgO 5-12份，本发明起燃温度低，冒口材料内金属液的凝固时间长，发热效果、保温效果好。
