Abstract

The invention relates to a gunning mix for small steel ladles. The technical scheme includes that the gunning mix is prepared from, by weight, 8-10% of alumina 8-12 mm in particle size, 11-15% of alumina 5-8 mm in particle size, 12-15% of forsterite 3-5 mm in particle size, 10-15% of magnesia spinel 1-3 mm in particle size, 30-35% of magnesia spinel not more than 1 mm in particle size, 3-5% of ZrC powder, 1% of Ni2GeO4, 1-5% of plasticizer and 3-6% of binding agent by uniform mixing, wherein the binding agent refers to one or more of hydrated alumina and sodium hexametaphosphate, and the plasticizer refers to ball clay or dextrin. The gunning mix for the small steel ladles succeeds in solving the problems about hot gunning of steel ladles and is capable of repairing steel ladle liners in use spaces of the small steel ladles by hot gunning construction to make the steel ladles longer in service life and reduce ton steel refractory consumption, thereby creating huge economic and social benefits.

Description

A kind of little ladle gunning refractory
Technical field
The present invention relates to gunning refractory, a kind of little ladle hot spray repair gunning refractory.
Background technology
In order to ensure little ladle using effect, it is matter of frequent occurrence that little ladle spray repair is repaired.Conventional gunning refractory is only used for cold State spray repair, needs to suspend little ladle to use, just can carry out repairing work after natural cooling (generally taking 2-3 days).And little steel When bag puts into production again, need previously baked to more than 1100 DEG C, cause whole Period Process the longest, be not only delayed production but also consume Take the energy.Therefore, gunning refractory can construct under hot state imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of the present invention is just to provide a kind of little ladle thermal jet Benefit gunning refractory, can effectively solve the problem that little ladle hot spray repair is repaired.
The technical scheme that the present invention solves is, a kind of little ladle gunning refractory, it is characterised in that be by following percentage by weight Meter: Alumina 12 8mm is 8～l0%, Alumina 8 5mm is l1～15%, forsterite 5 3mm is 12～15%, magnesium point Spar 3 one lmm be 10～15%, magnesia spinel≤1mm be 30～35%, ZrC powder 3～5%, Ni2GeO4Powder 1%, plasticizer 1～ 5%, bonding agent 3～6% mix homogeneously are made；Described: aluminium oxide >=88% of Alumina；Forsterite >=95%；Magnesia spinel ≥95%；ZrC≥90%；Ni2GeO4≥92%；Described bonding agent is one or both of hydrated alumina sodium hexameta phosphate Combination；Described plasticizer is ball clay or dextrin.
The present invention is a kind of little ladle gunning refractory, gap can be used to be constructed to little ladle bag by hot gunning at little ladle Lining is repaired, and makes little ladle long for service life, and ton little ladle is long for service life, and ton steel refractory consumption can than domestic like product Saving more than 120%, little ladle maintenance cycle is elongated, and labor strength reduces, and economic and social benefit is huge.
Four. detailed description of the invention
Below in conjunction with embodiment, the detailed description of the invention of the present invention is elaborated.
Embodiment 1
The present invention can use following percentage by weight meter in being embodied as: Alumina 12 8mm is 10%, Alumina 8 5mm is L5%, forsterite 5 3mm are 12%, and magnesia spinel 3 one lmm is 15%, magnesia spinel≤1mm is 35%, ZrC powder 3%, Ni2GeO4Powder 1%, plasticizer 3%, bonding agent 6% mixes, blender stir and make.
Embodiment 2
The present invention also can use following percentage by weight meter in being embodied as: Alumina 12 8mm is 10%, Alumina 8 5mm Being 12% for l5%, forsterite 5 3mm, magnesia spinel 3 one lmm is 15%, magnesia spinel≤1mm is 35%, ZrC powder 3%, Ni2GeO4Powder 1%, plasticizer 4%, bonding agent 5% mixes, blender stir and make.
Embodiment 3
(0012) present invention also can use following percentage by weight meter in being embodied as: Alumina 12 8mm is 10%, Alumina 8 5mm are l5%, forsterite 5 3mm is 12%, and magnesia spinel 3 one lmm is 15%, magnesia spinel≤1mm is 34%, ZrC powder 4%, Ni2GeO4Powder 1%, plasticizer 3%, bonding agent 6% mixes, blender stir and make.
In embodiment 1-3, alleged Alumina forsterite magnesia spinel Ni2GeO4, ZrC, bonding agent and plasticizer Identical with the component be given in Summary.
The gunning refractory of the present invention directly can carry out spray repair repairing to the little ladle liner of more than 1000 DEG C, greatly reduces Ton steel refractory consumption, can save the resistance to material of ton steel more than 120%, also save mass energy in addition, and little ladle maintenance cycle is elongated, Labor strength reduces, and economic and social benefit is huge.Gunning refractory of the present invention after tested, its test index such as following table:
The present invention has broad application prospects, and economic worth and technological value are huge.
