Data collected by blast-furnace sensors.

The data represent measured values of the main technological parameters of blast-furnace smelting. Two datasets are provided. The first dataset contains raw, noisy data with gross outliers, downloaded from the dispatch system. The second dataset consists of data that have been validated for reliability and labelled into classes. The collected data were synchronised. The following parameters were recorded at 1-hour intervals: total and specific gas pressure differences, peripheral gas temperature, top gas temperature, CO2 content of top gas, H2 content of top gas, top gas pressure, ore-to-coke ratio, blast flowrate, blast oxygen flowrate, hot blast pressure, hot blast temperature, cold blast pressure, and cold blast temperature. The Si content in hot metal was provided separately in the dataset. This dataset has the form of a multidimensional time series.
