use of ramming mass

September 21, 2020

In the core induction furnace, furnace body generally choose neutral ramming mass .The ramming material selected by the inductor varies with the operating conditions.Non-ferrous metal smelting furnace, often choose neutral dry ramming materials.Basic or neutral ramming materials are often used in ferrous metal smelting furnaces.

The ramming mass can be constructed by direct vibration or indirect vibration.The direct ramming method is to use the vibrator to directly ramming the refractory. After the rammer fully vibrates the refractory, the surface of the refractory is raked, a new layer of material is filled, and then the rammer is used to fully vibrate the refractory.This goes on layer by layer until the construction is over.

This method is time-consuming, but it can prevent the stratification between layers.Indirect vibration is the vibration power of the rammer which is fixed on the inner die or the outer die, and then transmitted to the refractory through the template, so as to make the rammer compact.
