Embodiment 1

[0041] Send 45 parts by weight of 0-3mm waste skateboard aggregates and 25 parts by weight of 3-8mm waste skateboard aggregates that have passed the inspection into the drum mixer for mixing and stirring. After mixing and stirring for 2 minutes, add 8 parts by weight of alum Soil powder, 9 parts by weight of sintered magnesium powder, 5 parts by weight of long aluminum A600 cement, 3 parts by weight of silica dust powder, and 5 parts by weight of α-aluminum trioxide micropowder are sent into a drum mixer for mixing and stirring. After stirring for 4 minutes, put the mixed material into a dry ton bag through a three-way valve discharge device, pack it at 500Kg / bag, fasten the opening mark and put it in storage for later use, and take samples to test the aluminum-magnesium-silicon type tank along the pouring The physical and chemical indicators of the materials (see Table 3 for the test results), and then transported to the construction work area for use after passing the test. ...

Embodiment 2

[0046] Send 50 parts by weight of 0-3mm waste skateboard aggregates and 20 parts by weight of 3-8mm waste skateboard aggregates that have passed the inspection into the drum mixer for mixing and stirring. After mixing and stirring for 2 minutes, add 5 parts by weight of alum Soil powder, 12 parts by weight of sintered magnesium powder, 3 parts by weight of long aluminum A600 cement, 5 parts by weight of silica dust powder, and 5 parts by weight of α-aluminum trioxide micropowder are sent into a drum mixer for mixing and stirring, and after mixing After stirring for 4 minutes, put the mixed material into a dry ton bag through the discharge device connected with the three-way valve, pack it at 500Kg / bag, fasten the opening mark and put it into the warehouse for standby, and take samples to test the aluminum-magnesium-silicon type tank Along the physical and chemical indicators of castables (see Table 4 for test results), after passing the test, they are transported to the repairi...

Abstract

The invention relates to the field of steel-making steel ladle refractory materials, in particular to an aluminum-magnesium-silicon pot edge castable and a preparation method thereof and provides an aluminum-magnesium-silicon pot edge castable capable of solving the technical problems of difficult steel ladle pot edge slag treatment, cracks produced in the baking process, poor heat stability in the high-temperature using process and the like of steel ladle pot edges and a preparation method. The castable is prepared from, by weight, 20-25% of 3-8 mm waste sliding plate aggregate, 45-50% of 0-3 mm waste sliding plate aggregate, 5-8% of alumina powder, 9-12% of sintered magnesium powder, 3-7% of long aluminum A600 cement, 3-5% of silica dust, 5-7% of alpha aluminum oxide micro powder, 0.015%-0.02% of explosion-proof fiber and 0.2-0.3% of admixture sodium hexametaphoshpate. The aluminum-magnesium-silicon pot edge castable can effectively solve the problems of poor steel ladle pot edge application property, cracks, low strength, poor heat stability, difficult steel ladle pot edge slag treatment and the like and is especially suitable for preparation of aluminum-magnesium-silicon pots.

Description

technical field [0001] The invention relates to the field of steel-making ladle refractory materials, in particular to an aluminum-magnesium-silicon type tank edge castable and a preparation method thereof. Background technique [0002] During the turnover and use of the ladle, the edge of the ladle tank generally does not touch the molten steel (slag), but sometimes when the tapping amount fluctuates, the molten steel contacts the edge of the tank when the amount of steel tapping is large. Therefore, the refractory material in this part is required to have good medium and high temperature strength, in order to balance the life of the ladle lining, reduce the consumption of ladle lining materials and improve the safety and reliability of the ladle. , specially choose aluminum-magnesium-silicon castables to solve the above problems. In the experiment, setting single factor variables in samples and burning samples, it is found that the construction performance is better when t...
