Example Embodiment
[0027] Example 1
[0028] Crush 3 parts by weight of the industrial waste slag from the production of high-carbon ferrochrome into 10mm blocks, then grind the blocks to a particle size of 100μm and mix with 97 parts by weight of cement raw meal powder to obtain mixed cement raw meal; The cement raw meal was calcined at 1250°C for 30 minutes, and then cooled to obtain cement clinker. Among them, the SiO in the industrial waste slag from the production of high-carbon ferrochrome 2 The weight percentage is 35%, Al 2 O 3 The weight percentage of MgO is 32%, the weight percentage of MgO is 30%, Fe 2 O 3 The weight percentage is 8%, the weight percentage of GaO is 1%, Gr 2 O 3 The weight percentage is 5%. Calculated according to the following cost and consumption, coal consumption is 140kg / T, coal price is 500 yuan / T, slag crushing, transportation, taxation and other expenses are 150 yuan / T (loss on ignition is 0), cement clinker is 280 yuan / T, conventional cement The profit of the fa...

[0029] Example 2
[0030] Crush 4 parts by weight of the industrial waste slag from the production of high-carbon ferrochrome into 15mm blocks, then grind the blocks to a particle size of 80μm and mix with 96 parts by weight of cement raw meal powder to obtain mixed cement raw meal; The cement raw meal was calcined at 1180°C for 40 minutes, and then cooled to obtain cement clinker. Among them, the SiO in the industrial waste slag from the production of high-carbon ferrochrome 2 The weight percentage is 33%, Al 2 O 3 The weight percentage of MgO is 30%, the weight percentage of MgO is 28%, Fe 2 O 3 Is 9% by weight, GaO is 1.5% by weight, Gr 2 O 3 The weight percentage is 7%. Calculated according to the following cost and consumption, coal consumption is 140kg / T, coal price is 500 yuan / T, slag crushing, transportation, taxation and other expenses are 150 yuan / T (loss on ignition is 0), cement clinker is 280 yuan / T, conventional cement The profit of the factory producing 1 ton of c...
