Electric furnace

The overall layout should be as small as possible under the premise of ensuring the reasonable operation of workers, so as to shorten the overall connection line, thereby reducing heat and electricity.
The material used in the smelting furnace should be as large as possible to ensure smooth movement of the current in case the copper bars are too small to heat up and then take away some of the electricity.

Since the sintered layer of the new furnace is thinner, the process of using the new furnace is very important. When disassembling a new furnace, try to avoid strong impact on the bottom and walls of the furnace, and avoid cracking or cracking of the furnace under strong impact. Therefore, in order to obtain the service life of the blast furnace, early furnace technology is required.

Frequently clean the dust in the machine room, the power cabinet and the copper bars connected to the induction coil to prevent the insulation from being lowered and failures. Frequently check whether the water flow and water pressure of each cooling water channel are normal. Regularly tighten the connecting bolts and nuts of each component to prevent bad contact from burning the components. Regularly maintain the pumping motor of the water cooling system and the motor of the hydraulic station, clean the hydraulic oil, and ensure the normal water supply and oil supply of the equipment. Regularly check the rated voltage and current of the equipment to prevent the protection circuit from malfunctioning. Regular, correct and careful maintenance is an important guarantee for extending the service life of the intermediate frequency furnace and ensuring safety.

Optimize and adjust the angle of the oxygen lance to avoid the direct effect of oxygen blowing on the electrode; optimize the use process of the oxygen lance and adjust the larger oxygen flow of the oxygen lance. The reasons for the fracture of electric furnace electrodes are divided into mechanical failure and electrical phase control.
Mechanical failure control is as follows: reasonable distribution. The distribution of various steels in the basket is reasonable to prevent the thin and light steel from forming a ball on the top of the furnace, which is difficult to go down, thus forming a large piece of scrap steel and shattering the pole; when melting, pay attention to the distribution of unmelted materials. For the generated bridge structure, by blowing oxygen or physically swinging, the charge will collapse at the position where the electrode is raised to avoid electrode fracture; the electrode installation should be reasonable and standardized to ensure stable clamping and installation; the electrode connection position is correct, and the electrode holder should be Above the connection location, and should not be caught on openings or rings.
