Magnesian high-strength gunning mix
The invention discloses a magnesian high-strength gunning mix, which comprises the following raw materials in parts by weight: 50-97 parts of a magnesian raw material, 1-8 parts of magnesium aluminate, 1-10 parts of a plasticizer and 1-10 parts of a burning promoter, wherein the magnesium raw material is selected from sintered magnesia, high-calcium magnesia and a magnesium-chromium reclaimed material. According to the gunning mix, magnesium aluminate and a magnesian raw material quickly react to generate a gel on the premise that water exists, so that the bonding strength is generated while the adhesion performance of the gunning mix is improved; a small amount of a sintering promoter is added, so that sintering can be promoted at a high temperature, and the high-temperature sintering strength is effectively improved; and the gunning mix is limited in liquid phase quantity formed at a high temperature, small in shrinkage, good in steel slag permeability resistance and not easy to formstructural peeling.
本发明公开了一种镁质高强度喷补料，它的原料包括50～97份的镁质原料、1～8份的铝酸镁、1～10份的增塑剂和1～10份的促烧剂；其中，所述镁质原料选自烧结镁砂，高钙镁砂和镁铬再生料。本发明中铝酸镁与镁质原料在有水的前提下，快速反应生成凝胶体，产生结合强度，同时还提升了喷补料的附着性能；添加少量的促烧剂，在高温下能够促进烧结，有效提升高温烧结强度；该喷补料在高温下形成液相量有限，收缩较小，抗钢渣渗透性好，不易形成结构剥落。
