How to Make Tundish Nozzle and Well Block Match with Tundish LiningPosted by annesheldon on March 26th, 2016 When choosing silica ramming mass as tundish lining, the expected service life could be 36-60 hours, but the service lives of tundish nozzle well block are not as long, in this case, how to ensure continuous casting? Here are two options:
There are some essential differences between graphite carburant and coal quality carburant: First: The raw material of those two carburant is different. Graphite carburant is made from filtered natural graphite, and coal quality carburant is produced from burning anthracite. Second: They have different features. Graphite carburant has features of low sulfur, low nitrogen phosphorus, high temperature resistance and good electrical conductivity etc., which are not available for coal quality carburant. Third: They have different absorptivities. Absorptivity of graphite carburant is more than 90%, and that’s why it can meet the using requirement even its fixed carbon is low (about 75%). Forth: Graphite carburant and coal quality carburant have quite different prices. Even the price of graphite recarburant is a little higher than that of coal quality carburant, its comprehensive cost is much lower.
