Embodiment 1
[0018] Use formula 1 to prepare blast furnace main iron trough: mix the ingredients according to formula 1 and stir them with a mixer to form castables, add castables to the mold installed in the main iron trough where molten iron flows, and naturally cure for 1 hour to demould to obtain blast furnace main iron ditch.
Embodiment 2
[0020] Use formula 2 to prepare the main iron trough of small blast furnace: mix the ingredients according to formula 1 and stir it with a mixer to make castables, add castables to the mold installed in the main iron trough where molten iron flows, and let it be naturally cured for 1 hour to demould to get the blast furnace main iron ditch.
Embodiment 3
[0022] Use Formula 3 to prepare the main iron trough of the small blast furnace: mix the ingredients according to Formula 1 and stir it with a mixer to make the castable, then add the castable to the mold installed in the main iron trough where the molten iron flows, and let it be naturally cured for 1 hour to demould to obtain the blast furnace main iron ditch.
