The difference between dry vibrating material and ramming material

Dry vibrating material and ramming material are new types of refractory castables developed over the years. They are developed under the basic theory of castables. Its key technology lies in self-reaction and self-sintering products at high temperature. It is necessary It is a high-temperature phase substance, and its particle gradation and binder are also more important. This castable was initially brought with the introduction of electric furnaces, and it was not long before the initial localization.

Dry vibrating material is a dry refractory mixture that does not add liquid. It is vibrated to obtain a dense construction body and can be used directly without maintenance and baking. It is called dry ramming material. The process principle is: mixing Add various load sintering agents to ensure the chemical reaction between materials at high or low temperature to obtain high-temperature phase products and ceramic bonding. The particle gradation of the materials is carefully equipped to ensure that the particles can move quickly under the action of a small vibration force. Fill all kinds of vacancies without remaining and insufficient materials at all levels, and then a higher bulk density can be obtained.

Dry vibrating materials are distinguished according to the material grade and the parts used. According to the material types, they are divided into siliceous, corundum, magnesia, magnesia-calcium, magnesia-aluminum, magnesia-aluminum spinel and other dry vibrators. According to the parts used, it can be divided into electric furnace bottom dry vibrating material, power frequency furnace melting groove dry vibrating material and central package working lining dry vibrating material, etc.

After all, to make up for it, after the construction of dry vibrating material and ramming material is completed, it is necessary to lay a layer of thin steel plate on it to avoid damage to its surface when scrap steel or molten iron is added. When producing the first few furnaces of steel , It should take time to investigate the surface of the working layer at the bottom of the furnace. If there is a pit, it should be repaired with the same material in time.
