We need to understand induction melting furnace operating procedures, also known induction melting furnace conditions of use and use common sense, induction melting furnace operating procedures before we have mentioned before, mainly with the following small series we look at induction melting furnace conditions of use and use common sense.
A. Induction melting furnace conditions:
1. The altitude does not exceed 3000m;
2. The ambient temperature is within the range of 3-40 ° C; 3.
Antifreeze measures need to be taken in areas below 0 ° C;
4. The monthly average monthly relative humidity of the use area is not greater than 90%;
5. Around No conductive dust, explosive gas and corrosive gas that can seriously damage metal and insulation.
6, there should be measures to prevent insects, rodents, as well as exhaust ventilation equipment and fire fighting equipment.
7. The trench should have a waterproof cement structure, with wooden or cement boards on top and drainage facilities, and good ventilation and heat dissipation.
8. The mainframe of the power supply should be well grounded (grounded according to the general low-voltage electrical equipment standards, and repeated grounding is allowed). Personal safety measures and electrical protective equipment should be used.
9. When designing cooling equipment, consider the backup water source that can supply cooling water to the furnace in the event of a power outage.
We know the operating conditions of the induction melting furnace, so we must pay attention to it later. In addition, today I will share with you some common knowledge about the use of the induction melting furnace, so that we can operate the induction melting furnace more safely.
B. Common sense of using induction melting furnace :
1. Before opening the furnace, check whether the electrical equipment, water cooling system, copper tube of the sensor are intact, otherwise it is forbidden to open the furnace.
2. Furnace melting loss should be repaired in time if it exceeds the regulations. Smelting is strictly prohibited in crucibles with excessive melting.
3. Special persons shall be responsible for power transmission and furnace opening. It is strictly forbidden to touch the sensors and cables after power transmission. Persons on duty are not allowed to leave the post without authorization. Pay attention to the external conditions of the sensor and the crucible.
4. When charging, check whether there is any flammable and explosive hazardous materials in the charge. If it should be removed in time, it is strictly forbidden to add cold and wet materials directly to the molten steel. After the molten liquid is filled to the top, it is strictly prohibited to add large materials. Just in case it gets covered.
5. It is strictly forbidden to mix iron filings and iron oxides when filling furnace and crucible. The crucible must be compact.
6. When the material is to be burned in the case of a cold furnace, the rated power should not be used immediately. Low-temperature heating should be used at 60% -75% of normal power to avoid cracks in the furnace lining. Increase the power to the normal process power and start the formal forging operation.
7. The billet should be placed correctly during the charging process to avoid jamming the top furnace lining.
8. The casting site and the pit in front of the furnace should be free of obstacles and water, so as to prevent molten steel from exploding on the ground.
9. The molten steel is not allowed to be too full. When the ladle is poured by hand, the two should cooperate with each other, walking smoothly, and not allowed to stop quickly. After pouring, the steel should be poured into the designated place.
10. The induction melting furnace room should be kept clean. It is strictly prohibited to bring flammable and explosive materials and other sundries into the room. Smoking is prohibited in the room.
