The refractory Ramming material is made of a highly proportion of granularity and powder and the proportion of a very low proportion. Methods Construction of scattered materials.
Because the Ramming material is mainly used for direct contact with the melting material, it is required that the granules and powder must have high volume stability, density and corrosion resistance. Those who are used for induced electric furnaces should also have insulation.
1. Character of Ramming material
The binding agent of the ramming material should be appropriate, some do not need a binding agent, and some only add a small amount of melting agent. Acid pounds are commonly used with binding agent such as sodium sodium silicate, silicate, and silicone. Among them, dried type pounds are mostly used for borate; alkaline mosaic mosaic chlorine chloride and sulfate are commonly used in mosaic mosaic mosaic mosaic mosaic mosaic; also often uses carbon -containing organic matter and temporary binding agent at high temperatures. Essence Among them, the dry melting agent with an appropriate amount of iron containing iron. Chromium pounds are commonly used in lucky.
Compared with other irregular refractory materials of similar materials, the pounds are dry or semi -dry, and the dense structure is obtained by a strong tincture. Only by heating to the sintering temperature can the combination have strength.
After the formation of the mixing material, it can be used to promote hardening or sintering according to the hardening characteristics of the mixture. If it contains inorganic chemical binding agents, it can be disassembled and baked after it is quite intensive; those who contain the combination of thermoplastic carbon, after cooling, have a considerable strength and then remove the mold. The hardened binding agent at normal temperature often sintering with molds after pounding.
The materials composed of pounding materials are divided into it: clay, high aluminum, charcoal, magnesium and white cloud stone.
2. High aluminum、ramming material
First add the coarse, fine aggressive agent (high aluminum cement) in the specified ratio, and add a dry mixing 1 ~ 2 minutes in the mandatory mixer, and then add quantitative water for mixing and stirring for about 5 minutes. Construction: Mixed mixing is 80 ~ 100mm. Use the windy hammer continuously and uniformly to achieve the number of reciprocated multiple times
