Embodiment 1
[0059] A gas-permeable material for a converter and a preparation method thereof. The steps of the preparation method described in this embodiment are:
[0060] In the first step, 45-55wt% magnesia fine powder, 5-10wt% magnesia-aluminum spinel fine powder, 1-5wt% α-Al 2 o 3 Micropowder, 5-10wt% aluminum hydroxide, 1-5wt% aluminum fluoride, 1-5wt% anhydrous magnesium sulfate, 1-5wt% zinc oxide, 1-5wt% dodecylbenzenesulfonic acid Sodium, 1-5wt% fatty alcohol polyoxyethylene ether sodium sulfate, 0.1-1wt% sodium tripolyphosphate and 1-5wt% calcium aluminate cement are mixed to obtain a mixture, and 15-20wt of the mixture is added % water, stirred evenly, poured and molded, cured for 10-16 hours to obtain a solidified green body.
[0061] The second step is to dry the cured body at 90-120°C for 12-18 hours, and then heat-treat it at 1450-1550°C for 5-7 hours to obtain pre-fired material; The material is crushed and sieved to obtain granular material A with a particle size of l...
Embodiment 2
[0066] A gas-permeable material for a converter and a preparation method thereof. The steps of the preparation method described in this embodiment are:
[0067] In the first step, 50-60wt% magnesia fine powder, 1-5wt% magnesia-aluminum spinel fine powder, 5-10wt% α-Al 2 o 3 Micropowder, 1-5wt% aluminum hydroxide, 5-10wt% aluminum fluoride, 5-10wt% anhydrous magnesium sulfate, 1-5wt% titanium dioxide, 1-5wt% sodium lauryl sulfate, 1 ~5wt% sodium carboxymethylcellulose, 0.1~1wt% sodium hexametaphosphate and 1~5wt% calcium aluminate cement are mixed to obtain a mixture, and then 10~16wt% of water is added to the mixture, and stirred homogeneous, casting and curing for 15 to 20 hours to obtain a solidified green body.
[0068] The second step is to dry the cured green body at 90-120°C for 15-20 hours, and then heat-treat at 1500-1600°C for 5-7 hours to obtain pre-fired material; The material is crushed and sieved to obtain granular material A with a particle size of less than ...
Embodiment 3
[0073] A gas-permeable material for a converter and a preparation method thereof. The steps of the preparation method described in this embodiment are:
[0074] The first step, 40-50wt% magnesia fine powder, 1-5wt% magnesia-aluminum spinel fine powder, 5-10wt% α-Al 2 o 3 Micropowder, 5-10wt% aluminum hydroxide, 1-5wt% aluminum fluoride, 5-10wt% anhydrous magnesium sulfate, 1-5wt% titanium dioxide, 1-5wt% sodium lauryl sulfate, 1 ~5wt% sodium carboxymethylcellulose, 0.1~1wt% sodium hexametaphosphate and 1~5wt% calcium aluminate cement are mixed to obtain a mixture, and then 15~20wt% of water is added to the mixture, and the mixture is stirred Uniform, pouring molding, curing for 10 to 16 hours to obtain a solidified green body.
[0075] The second step is to dry the cured body at 90-120°C for 18-24 hours, and then heat-treat it at 1400-1500°C for 5-7 hours to obtain pre-fired material; The material is crushed and sieved to obtain granular material A with a particle size of ...
