Abstract
The invention relates to a gunning mix for medium-sized steel ladle, which can effectively solve the problem of steel ladle hot gunning. According to the technical scheme, the gunning mix is prepared by uniformly mixing the following components in percentage by mass: 8-10% of No. 12 corundum of which the granularity is 8mm, 11-15% of No. 8 corundum which the granularity is 5mm, 12-15% of No. 5 forsterite of which the granularity is 3mm, 10-15% of No. 3 magnesium spinelle of which the granularity is 1mm, 30-35% of magnesium spinelle of which the granularity is less than and equal to 1mm, 3-5% of ZrC powder, 1% of Ni2GeO4 powder, 1-5% of plasticizer, and 3-6% of binder, wherein alumina in corundum is greater than and equal to 95%; forsterite is greater than and equal to 95%; magnesium spinelle is greater than and equal to 95%; ZrC is greater than and equal to 90% and Ni2GeO4 is greater than and equal to 92%, the binder is one or a combination of hydrated alumina and sodium hexametaphosphate and the plasticizer is a ball clay or dextrin. Since the ladle lining can be repaired by a hot gunning construction at usage intervals of the ladle according to the invention, the service life of the ladle is long, the consumption of refractory materials per ton of steel is low and huge economic and social benefits are achieved.
Description
One. technical field
The present invention relates to Gunning refractory, particularly a kind of medium-sized ladle hot gunning Gunning refractory.
Two. background technology
In order to guarantee medium-sized ladle result of use, it is matter of frequent occurrence that medium-sized ladle spray repair is repaired.Conventional Gunning refractory can only need to suspend medium-sized ladle to use for cold conditions spray repair, and naturally cooling (conventionally taking 2-3 days) just can carry out repairing work afterwards.And medium-sized ladle is when again put into production, need previously bakedly to more than 1100 ℃, cause whole Period Process very long, not only incur loss through delay production but also expend the energy.Therefore, Gunning refractory can under hot state, construct imperative.
Three. summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the present invention's object is just to provide a kind of medium-sized ladle hot gunning Gunning refractory, can effectively solve the problem that the hot gunning of Shaped Steel bag is repaired.
The technical scheme that the present invention solves is, a kind of medium-sized ladle Gunning refractory, it is characterized in that, by following weight percent meter: corundum 12-8mm is that 8～l0%, corundum 8-5mm are that l1～15%, forsterite 5-3mm are 12～15%, magnesia spinel 3 one lmm are 10～15%, magnesia spinel≤1mm is 30～35%, ZrC powder 3～5%, Ni
2geO
4powder 1%, softening agent 1～5%, bonding agent 3～6% mixes to be made; Described: aluminum oxide>=88% of alumina; Forsterite>=95%; Magnesia spinel>=95%; ZrC>=90%; Ni
2geO
4>=92%; Described bonding agent is one or both the combination that Shui closes Yangization Lv ﹑ Sodium hexametaphosphate 99; Described softening agent is ball clay or dextrin.
The present invention is a kind of medium-sized ladle Gunning refractory, can use gap to construct Shaped Steel bag cylinder-packing is repaired by hot gunning at medium-sized ladle, make medium-sized ladle long service life, the medium-sized ladle long service life of ton, ton steel refractory consumption can be saved more than 120% than domestic like product, the Shaped Steel maintenance packet cycle is elongated, and labor strength reduces, and economic and social benefit is huge.
Four. embodiment
Below in conjunction with embodiment, the specific embodiment of the present invention is elaborated.
Embodiment 1
The present invention can adopt following weight percent meter in concrete enforcement: corundum 12-8mm is 10%, corundum 8-5mm is that l5%, forsterite 5-3mm are 12%, and magnesia spinel 3 one lmm are 15%, magnesia spinel≤1mm is 35%, ZrC powder 3%, Ni

4powder 1%, softening agent 3%, bonding agent 6% mixes, and by stirrer, is stirred and is made.
Embodiment 2
The present invention also can adopt following weight percent meter in concrete enforcement: corundum 12-8mm is 10%, corundum 8-5mm is that l5%, forsterite 5-3mm are 12%, and magnesia spinel 3 one lmm are 15%, magnesia spinel≤1mm is 35%, ZrC powder 3%, Ni
2geO
4powder 1%, softening agent 4%, bonding agent 5% mixes, and by stirrer, is stirred and is made.
Embodiment 3
The present invention also can adopt following weight percent meter in concrete enforcement: corundum 12-8mm is 10%, corundum 8-5mm is that l5%, forsterite 5-3mm are 12%, and magnesia spinel 3 one lmm are 15%, magnesia spinel≤1mm is 34%, ZrC powder 4%, Ni
2geO
4powder 1%, softening agent 3%, bonding agent 6% mixes, and by stirrer, is stirred and is made.
In embodiment 1-3, alleged Fan Tu ﹑ Mei Gan Lan Shi ﹑ magnesium Jian Jing Shi ﹑ Ni
2geO
4, ZrC, bonding agent be identical with the component providing in summary of the invention part with softening agent.
Gunning refractory of the present invention can directly carry out spray repair repairing to 1000 ℃ of above medium-sized ladle liners, greatly reduce a ton steel refractory consumption, can save the resistance to material of ton steel more than 120%, in addition also saved mass energy, the Shaped Steel maintenance packet cycle is elongated, labor strength reduces, and economic and social benefit is huge.After tested, its test index is as following table for Gunning refractory of the present invention:
The present invention has broad application prospects, and economic worth and technological value are huge.
