Talking about the construction technology of dry ramming material

The dry ramming material can be constructed by two methods: direct oscillation or direct oscillation. The direct ramming method of magnesia-calcium sand is to directly ram the refractory material with an oscillator. The surface is filled with a new layer of material, and then fully tapped with a rammer. This is carried out layer by layer until the end of the construction. Although this method is time-consuming, it can prevent delamination between layers. Direct oscillation is the oscillating force generated by the rammer fixed on the inner mold or the outer mold, and then transmitted to the refractory material through the template, thereby making the ramming material finer.

The filling density of the dry ramming material after molding is closely related to the pre-compression and the oscillation force of the oscillator, the oscillation frequency and the number of oscillators. The pre-compression can increase the initial filling density. Increasing the oscillation frequency can also increase the filling density. When the ramming frequency is above 50Hz, increasing the oscillating force can effectively improve the filling density of the oscillating body. When the dry oscillating material is not pre-pressed, the oscillating force generated by two perpendicular ramming machines can also achieve sufficient and fine effects.

The dry ramming material can be constructed by two methods: direct oscillation or direct oscillation. The direct ramming method is to directly ram the refractory material with a vibrator. Fill a new layer of material, and then use a rammer to fully tap it. This is done layer by layer until the end of the construction. Although this method is time-consuming, it can prevent the phenomenon of delamination between layers.

Direct oscillation is the oscillating force generated by the rammer fixed on the inner mold or the outer mold, and then transmitted to the refractory material through the template, so as to make the ramming material finer. The filling density and preloading of the dry ramming material after molding It is closely related to the oscillating force of the oscillator, the oscillating frequency and the number of oscillators. Preloading can increase the initial filling density. Increasing the oscillating frequency can also increase the filling density. When the ramming frequency is above 50Hz, the oscillating force can be increased. It can effectively improve the filling density of the oscillating body. When the dry oscillating material is not pre-pressed, the oscillating force generated by the two perpendicular rammers can also achieve a sufficient and fine effect.
