Ferro Alloy
For this reason, breathable holes must be inserted, that is, a round steel is inserted into the air-impermeable part of the fabric. Do not open it. Just loosen the charge and draw out the furnace gas. This is a method often used in ferrosilicon smelting to increase breathability. operate.

High Carbon Ferro Silicon
Parts where the ventilated eyes should be pierced:
1. The bottom of the vertebral body or the large surface of the material surface has poor air permeability.
2. Sting around the fire site.

Silicon Ferro
Pricking breathable eyes can achieve the following purposes:
1. Make the large amount of carbon monoxide gas generated after the reaction escape quickly, which not only increases the preheating surface of the furnace material, but also increases the air permeability of the material surface, expands the crucible and accelerates the chemical reaction in the furnace.
2. Reduce the ignition phenomenon and reduce heat loss.
