Precautions for dry and rammed materials

Precautions:

Before mixing, the site or mixing equipment must be cleaned and other impurities, especially steel scraps and iron, must not be mixed into the material. After stopping the furnace, add a furnace cover and slowly cool down.

This type of product can be directly used by users without any additives (including water)

This product is made entirely of specially made * materials, which have better performance in many aspects such as fire resistance, slag resistance, corrosion resistance, and thermal shock performance. Therefore, it has been determined and ensured that this material can be used as a high-quality lining material with stable and excellent performance under harsh or even harsh smelting conditions. The scope of application is more extensive, such as the smelting of stainless steel, high alloy steel, and high-speed tool steel.

The ramming material is usually rammed with an air hammer or a ramming machine, with a thickness of approximately 50-150mm for each ramming. Refractory ramming materials can be constructed at room temperature, such as using thermoplastic organic materials that can form carbon bonds as binders. Most of them are mixed evenly in the hot state and immediately constructed. After forming, different heating methods are used to promote hardening or sintering based on the hardening characteristics of the mixture. For ramming materials containing inorganic chemical binders, they can be demolded and baked after self hardening to a certain strength; Materials containing thermoplastic carbon binders should be cooled to appropriate strength before demolding. After demolding, they should be quickly heated to carbonize before use. The sintering of refractory ramming material furnace lining can be carried out in advance before use, or it can be completed by using appropriate thermal treatment system during the first use. The baking and heating system of ramming materials varies depending on the material used. The main purpose of ramming materials is to cast smelting furnace linings that come into direct contact with molten materials, such as blast furnace iron hooks, steelmaking furnace bottoms, induction furnace linings, electric furnace tops, and rotary kiln discharge areas. In addition to forming integral furnace linings, they can also be used to manufacture large prefabricated components

After years of practical experience, the furnace temperature is lower than the tapping temperature of ordinary steel, and the furnace life is longer.

Using this product reduces worker intensity, reduces costs, and improves economic benefits
