Introduction to the composition structure and function of ramming material

Today, Luoyang Quantong Kiln Industry Co., Ltd. will take you to understand the composition and function of the ramming material:

The ramming material uses magnesium chloride, sulfate and other aqueous solutions, as well as phosphates and their polymers as binders, and also often uses higher carbon-containing organics and temporary binders that form carbon bonds at high temperatures. Chromium Glauber's salt is often used as a binder for ramming materials. High-alumina and corundum ramming materials are often used as binders with inorganic substances such as phosphoric acid and aluminum phosphates, chlorides, and sulfates. Due to the reaction between phosphoric acid and activated alumina in the ramming material, the formation of water-insoluble aluminum orthophosphate deposits and agglomeration and hardening. To prolong the shelf life of the ramming material, it is necessary to add appropriate preservatives to prevent or delay the agglomeration and hardening. Generally, oxalic acid is used as a preservative.

The function of the ramming material Generally, the ramming material is mainly used for the parts that are in direct contact with the molten material. It is required that the refractory material must have excellent volume stability, fineness and erosion resistance, so high temperature firing or electrofusion raw materials are generally used. The particle size of the ramming material is related to the use part and the construction method. Most of the ramming materials have low normal temperature strength before sintering, and some are not high in medium temperature strength. An excellent combination was then achieved.

The refractory performance of quartz sand ramming material has been indicated by a large number of production and use data, the function is more stable, and the advantages of use are remembered, and through the accurate ratio of materials and auxiliary materials, the waste of production materials is greatly reduced and production consumption is saved. The ramming material has high stability and corrosion resistance at high temperature.
