Abstract:
In this article, we will share some info about blast furnace main iron trough wear conditions and how to improve the efficiency of main iron runner trough with making 3D laser scans analysis.<br />We are working in Kardemir Blast Furnace 5 and we are process engineers. In Blast Furnace 5, we have 2 main iron runner troughs and their dimensions are 13 (length) x 1,3 (width) meters and they can keep nearly 32 tons of iron inside. We are checking their temperatures with 24 of thermocouples. We are using castable refractories based on alumina and silicon carbide aggregates.<br />In each campaign we are usually getting 230 k ton hot metal from the troughs and after that we are wrecking the trough and repair with castable refractory and it costs so much for us. And inside we discussed this and try to make a 3D laser scan analysis for trough. After the scan we saw the wear areas of the troughs and learned that we can get nearly 35 k ton hot metal more from the troughs. So this is really great for us and it decreased our costs for castable refractories.<br />So we have really improved the efficiency of our main iron troughs.
