Three requirements for melting in induction melting furnace
1. The total amount of slag theoretically stipulates that 1.5-2% of 2-3% induction melting furnace must be guaranteed, that is, 25-30 kg of lime is indispensable, 5-8 kg of fluorite, 1.2-1.5 kg of reducing agent/furnace, check one Check the amount of lime on the day and the monthly amount of Ca-Si powder, and you know that it is far from meeting the requirements.
2. The slag change is not less than 2.5-3 times, and the oxidation slag is replaced with new slag; most of the pre-deoxidation slag sampling is replaced with new slag; the alloy is added to cool the steel to replace the new slag. These three times must be impossible.
3. H13 final deoxidation aluminum insertion 0.8-1.0 kg/ton, ensure that the electrode rod has ≥0.004% aluminum content, do not add aluminum powder to the ladle to replace the final deoxidation aluminum insertion; if the medium chromium is smelted, the high chromium abrasive steel will dissolve in the steel Oxygen is low. If the smelting process is not good enough to add aluminum, it will not be added.
