The ramming process of intermediate frequency furnace lining material is a relatively complex process, in which the knotting process is a very important link, which can affect the service life of the furnace. So, what matters should we pay attention to in the process of tying, so as not to affect the service life of the furnace?

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 tying the knot, the power supply and water supply system must also be prepared in advance through the staff of each project. Of course, it also includes that staff are not allowed to carry any combustible materials to the work site, and of course, it also includes some items such as mobile phones and keys.

2, the process of intermediate frequency furnace ramming material adding sand is a more strict process, such as sand must be added at one time, do not add times, of course, when adding sand to ** sand flat in the bottom of the furnace, can not be piled into a pile, otherwise it will cause the sand particle size separation.

3. When tying a knot, I want to operate it by shaking it first and then shaking it. And pay attention to the technique, the process of operation should be first light and then heavy. And the rocker should also be inserted to the bottom once, and each time when the rod is inserted, shake eight to ten times.

4, after the bottom of the furnace is finished, be sure to smoothly put into the dry pan Monium. In this way, the forming is relatively standard, and it is generally a standard annular triangle. Of course, there are many more steps to pay attention to in the entire knotting process. And each step cannot be ignored.

What aspects affect IF furnace lining?

Intermediate frequency furnace lining is intermediate frequency furnace equipment. An important part, because the intermediate frequency furnace lining has many uses, it has a great impact on the results it can achieve in use, the following Xiaobian will introduce what aspects affect the intermediate frequency furnace lining.

Five aspects that affect the lining of an intermediate frequency furnace:

1, neutral lining material manufacturers of intermediate frequency furnace loading criteria: first of all to determine the converter reasonable loading amount, suitable molten iron, scrap ratio. However, in determining the loading capacity of the converter, in addition to considering the appropriate furnace volume ratio, the appropriate depth of the molten pool should also be considered, so as to protect the bottom of the tube from the impact of the oxygen jet, and the depth of the molten pool must exceed the penetration depth of the oxygen flow to the molten pool.

2. Oxygen supply criteria of intermediate frequency furnace: To determine scientific and reasonable oxygen supply criteria, the speed of impurity removal, melting pool heating and slag formation has an impact on the converter smelting and the service life of the lining.

3, neutral lining material manufacturers intermediate frequency furnace temperature criteria: under the premise of molten steel pouring content, the steelmaking process temperature control and the lower the end temperature of the use of lining life is more favorable.

4, the furnace volume ratio of medium frequency furnace: the furnace volume ratio is too large will increase the cost of steelmaking, and the furnace volume ratio is too small will show splashing, thereby reducing the service life of the furnace lining. So it is very important to design a reasonable furnace volume ratio of intermediate frequency furnace.

5, the quality of the original data: when the intermediate frequency furnace equipment steelmaking, the quality of the original data used has a great impact on extending the life of the lining.
