What should I do if the intermediate frequency charge is knotted?

The ramming process of the intermediate frequency furnace charge is a relatively complicated process, and the knotting process is a very important link, which can affect the service life of the furnace. Then, what should we pay attention to during the knotting process to ensure that it does not affect the What about the service life of the furnace? Let's hear what the Hubei Yuanzhen knotting material manufacturer has to say!

1. The basic is of course the standard operation process, but in addition, there are many precautions in the knotting process of the intermediate frequency furnace ramming material. For example, before knotting, ensure the power supply and The improvement of the water supply system should also be prepared in advance by the staff on each project. Of course, it also includes that the staff are not allowed to carry any combustibles on the work site, of course, including mobile phones, keys and other items.

2. Adding sand during the ramming process of the intermediate frequency furnace is a process with strict requirements. For example, the sand must be added at one time, and should not be added in batches. Of course, when adding sand, ensure that the sand is spread on the bottom of the furnace. Do not pile up in a pile, otherwise it will cause the particle size of the sand to separate.

3. When tying the knot, I have to operate it according to the method of shaking first and then vibrating. And pay attention to the method to ensure that the operation process should be light first and then heavy. And the joystick should be inserted to the bottom at one time, and every time When inserting the rod, shake it 8 to 10 times.

4. After the bottom of the furnace is knotted, it must be ensured that it can be put into the dry pot stably. This can ensure that the forming is relatively standard, usually a standard annular 3-corner ring. Of course, during the entire knotting process, it is necessary to There are many steps to pay attention to. And each step cannot be ignored.

What aspects affect the lining of the intermediate frequency furnace?

The intermediate frequency furnace lining is an important part of the intermediate frequency furnace equipment. Because the intermediate frequency furnace lining has many uses, it has a great impact on the results it can achieve in use. The following editor will introduce the impact of the intermediate frequency furnace lining. Which aspects are there.

5 aspects that affect the lining of the intermediate frequency furnace:

1. Loading criteria for intermediate frequency furnaces of neutral furnace lining material manufacturers: First of all, determine the reasonable loading volume of the converter, suitable molten iron, and scrap steel ratio. However, when determining the loading volume of the converter, in addition to considering the appropriate furnace capacity ratio, Consideration should also be given to ensuring the proper depth of the molten pool, in order to protect the bottom of the tube furnace from the impact of the oxygen jet, and the depth of the molten pool must exceed the penetration depth of the oxygen flow into the molten pool.

2. Oxygen supply criteria for intermediate frequency furnaces: It is necessary to determine scientific and reasonable oxygen supply criteria to ensure the removal of impurities, the temperature of the molten pool and the speed of slag making, which have an impact on the enhanced smelting of the converter and the service life of the furnace lining.

3. Temperature criteria for intermediate frequency furnaces: on the premise that molten steel is satisfied, the lower the temperature in the steelmaking process and the lower the final temperature, the better the service life of the furnace lining.

4. The furnace volume ratio of the intermediate frequency furnace: if the furnace volume ratio is too large, the cost of steelmaking will increase, while if the furnace volume ratio is too small, splashing will occur, thereby reducing the service life of the furnace lining. Therefore, a reasonable intermediate frequency furnace should be designed. The furnace capacity ratio is very important.

5. The quality of raw materials: When making steel in the intermediate frequency furnace equipment, the quality of the raw materials used has a great influence on prolonging the life of the furnace lining.
