The characteristics of pig iron in the furnace are different from those of steel plates. The temperature of pig iron furnace rises slowly, but it takes a long time to release heat and needs regular maintenance. However, the steel plate furnace heats up quickly and cools down quickly, and at the same time, it needs less maintenance work in the later stage. If you want continuous heating, you can consider pig iron furnace; If the frequency of use is high and the temperature is expected to rise rapidly, then steel plate can be selected.
