Intermediate
frequency furnace ramming material has many names, including dry ramming
material vibration of intermediate frequency furnace, medium frequency furnace lining
materials, intermediate frequency furnace refractory material, and intermediate
frequency furnace dry vibration material. All those names are saying the same refractory product, and the properties
and usage of all of them are the same. Intermediate frequency furnace ramming
material refers to a kind of unshaped refractory
products which are applied in the method of ramming (by human or machine), and
then becomes hard in heating.
According to
chemical properties, ramming material can be divided into acidic, neutral and alkaline
ramming material. Acid intermediate
frequency furnace ramming material is mainly made from high purity quartz
and fused silica. During composite period, sintering agent uses composite
additive as main material. Neutral intermediate frequency furnace ramming
material uses alumina, high alumina material as main raw materials, it also
uses composite additive as sintering agent. What makes alkaline ramming
material different from the above two kinds of ramming materials is that its
main raw materials are high purity fused corundum, high purity fused magnesia
and high purity spinel. And also it uses composite additive as sintering agent.
The above three kinds of ramming materials which are acidic, neutral and alkaline
intermediate frequency furnace ramming materials are widely used for coreless intermediate
frequency furnace and cored induction furnace.
