Dry ramming materials do not add water, do not add liquid binder, only under the action of vibration force, can form a dense and uniform whole, by heating thermosetting binder or ceramic sintering agent to produce strength. ** The small editor of the dry punching material factory will summarize the construction method and application range of dry ramming materials.

Dry type and application range of dry ramming materials:

The types of dry ramming materials are: acid ramming materials (silica sand and silica, zircon), neutral ramming materials (corundum, mullite), alkaline ramming materials, (magnesium, magnesium aluminum) and carbon and silicon carbide ramming materials (corundum - silicon carbide carbon, alumina - carbon, magnesia - carbon, magnesia - calcium oxide - carbon, etc.)

Dry on a core induction furnace, the furnace body generally uses neutral dry ramming material. The dry ramming material used for the sensor varies with the conditions of use. Neutral dry ramming materials are often used in non-ferrous metal smelting furnaces. In ferrous metal smelting furnaces, alkaline or neutral dry ramming materials are often used.

Dry two, dry ramming material construction technology:

Dry ramming materials can be constructed by direct vibration or indirect vibration. Direct ramming method is to use a vibrator directly ramming refractories, fully vibrate a layer of refractories with the rammer, rake its surface, then fill with a new layer of materials, and then fully vibrate with the rammer. This is done layer by layer; Until construction is finished. Although this method is time-consuming, it can avoid layering between layers. Indirect vibration is the vibration force generated by the rammer fixed on the inner or outer die, and then transmitted to the refractory through the template, thus densifying the ramming material.

The filling density of dry ramming material after molding is closely related to the size of vibration force, vibration frequency and the number of vibrators. Preloading can increase the initial filling density. Increasing the vibration frequency can also increase the filling density. When the ramming frequency is above 50Hz, increasing the vibration force can effectively improve the filling density of the vibrator. When the dry vibrating material is not prepressed, the vibration force generated by two perpendicular rammers can also achieve full densification.
