The tapping trough is the channel for the circulation of molten iron. Refractory materials are selected as the lining to ensure the circulation of molten iron to the molten iron tank. What kind of refractory material is good for the cast iron trough? The refractory materials used for the tapping ditch are divided into permanent layer and working layer. Generally, the permanent layer is built with clay brick, which can be used for a long time without damage. The working layer is made of castable or ramming material according to the use requirements of the tapping trough.
While understanding the quality of refractory materials used in the tapping ditch, for the working layer of the tapping ditch, whether to select castable or ramming material as the lining, what kind of castable or ramming material is selected, and whether it is suitable for the lining of the tapping trough? These are all considered by the customer when purchasing refractory materials for iron casting ditch.
The refractory materials used for the working layer of the tapping ditch include castable and ramming materials. Which kind of refractory material is better for the tapping trough?
The castable for the tapping trough is a common refractory material for the tapping trough. It is made of aluminum silicon carbide carbon. As the refractory material for the lining of the tapping ditch, during construction, the aluminum silicon carbide carbon castable is first put into the mixer for mixing, and then poured into the tapping ditch with the mold installed. After pouring, it is cured, and then baked, The water in the poured lining of the iron ditch castable can be completely removed before it can be put into use.
Tapping trough ramming material is also a common refractory material for tapping ditch, and the selected material is aluminum silicon carbide carbon. Aluminum silicon carbide carbon ramming material is used as the inner lining of the tapping ditch. During construction, the ramming material shall be scattered in the iron ditch and rammed with air hammer or electric hammer. According to the requirements of the technical department, it shall be rammed in layers until it reaches the required thickness.
What kind of refractory material should be used for the cast iron trough? We explain from the most intuitive point, that is, the applicable environment of the cast iron ditch. For example, for the new cast iron trough, castable is generally used for lining, and ramming material can also be used for lining. The lining poured by castable has good integrity and strong resistance to slag erosion; The tapping trough is lined with ramming material, which is convenient for construction and can be completed and put into use in a short time.
