**4. Conclusions**

In this study, microwave heating effects were discussed in detail, which can be very useful in verifying the microwave-assisted carbothermal reduction process of hematite slab in iron-making plants. Even though the findings are valuable in optimizing microwave heating parameters for reduction, further verification is needed before implementing them in plants. Numerical simulations of heat transfer in onedimensional hematite 20 cm x 20 cm slab under microwave irradiation by considering conduction, convection, and radiation effect, concludes the following
