Matters needing attention in the knotting process of wear-resistant ramming material

The ramming material is made of silicon carbide, graphite, electric calcined anthracite as raw materials, mixed with a variety of ultra-fine powder additives, and fused cement or composite resin as a binder. Filling material for masonry voids or masonry leveling layer. Ramming material has good chemical stability, erosion resistance, wear resistance, shedding resistance, thermal shock resistance, and is widely used in metallurgy, building materials, non-ferrous metal smelting, chemical industry, machinery and other manufacturing industries .

The whole process of wear-resistant ramming material has many steps, and knotting is some of the more important processes. And the process of knotting can also affect the service life of the furnace. What should we pay attention to in the process of knotting , to ensure that it does not affect the service life of the furnace?

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

2. Sand adding in the process of wear-resistant ramming material is a relatively strict process. For example, sand must be added at one time, and should not be added in stages. Of course, when adding sand, make sure 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, it should be operated 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 and then heavy. And the joystick should be inserted to the bottom at one time, and every time the rod is inserted Shake 8 to 10 times at all times.

4. After the bottom of the furnace is finished, be sure to put it into the dry pot stably. In this way, it can ensure that the shape is relatively standardized, and it will generally be a standardized 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.
