Structural composition of refractory dry ramming mass

Refractory dry ramming mass is dry or semi-dry and loose, and most of them have no binder before forming, so only strong ramming can obtain a dense structure. Most ramming materials have low room temperature strength before sintering, and some medium temperature strength is not high, and a strong bond can only be obtained after sintering or coking the phosphorus compounds in the binder when heated.

Refractory dry ramming mass is granular and powdered material made from refractory raw materials, usually in loose form with a suitable binder made by reasonable grading and mixing exercises. Similar to dry-hard pouring materials, but some have no no-bake binder. Usually, it needs to be constructed by strong ramming, so it is called ramming material.
product composition.
The granular and powdery materials of refractory dry ramming mass account for a relatively high proportion in the ramming material, while the proportion of combination agents and other ingredients is relatively low, and even all of them are composed of granular and powdery materials. Refractory dry ramming mass generally does not add additives such as plasticizers and retarders. The water content is also very low. When using a water-insoluble organic combination, there is no water in the mixture. In some products, refractory fibers are also used as reinforcement. Ramping material is mainly used as a lining material for various smelting furnaces that directly contact molten materials. In addition to forming the entire furnace lining, it can also be used to manufacture large-scale products.
