Carbon Lining

Carbon Lining ‫ﻣﻮاد ﻧﺴﻮز ﻛﺮﺑﻨﻲ‬ Carbon Linings are commonly used in electric furnaces for smelting FeCr, FeMn, FeSi, MnSi, Si-met, FeSi, CaC 2, P and also Aluminum electrolysis cells.

Cold Ramming Paste: Cold ramming paste is produced in different grades and widely used in Smelting Arc Furnaces (SAF), Aluminum Electrolysis cells and blast Furnaces. The installation temperature of cold ramming paste is 25-40°c. Hot Ramming Paste: Hot ramming paste is also used in Smelting Arc Furnaces (SAF), Aluminum Electrolysis Cells and Blast Furnaces. The hot ramming paste should be heated up to 80-90°c 80-90°c before installation. instal lation. SiC Ramming Paste: SiC ramming paste is a mixture of SiC, carbon and some additives that is produced on different grades. Due to high thermal shock resistant of sic ramming, its main application is in such areas- like Furnace Tap holes.

Carbon Block It is widely used as refractory materials in ferroalloy furnace, blast furnace, calcium carbide furnace, and the aluminum cells. Carbon block has the properties of superior electric and thermal conductivity, high chemical and bulk stability, as well as high strength in electrolysis under high temperature. Carbon blocks are produced on different grades.
