Blast furnace Wikipedia

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with

produce molten iron and slag. The Blast Furnace operates continuously with molten iron and slag being cast out of the furnace regularly, by tapping three (3) tapholes in the hearth in sequence every 2 to 3 hours. To ensure that good iron quality is produced in the furnace, the temperature within the melting zone of the furnace is maintained at 1500oC. This requires that the refractory lining

In the circulation method, the cleaning solution is intermittently circulated through the unit until the chemical content and the iron and copper content of the cleaning solution reach a constant value, indicating the end of the reaction between the solvent and deposits. This method is suitable for units with positive liquid flow paths, and it allows monitoring of the cleaning operation at

Slags and dross from electric melting, if not totally removed at the melting furnace, will be transferred into the pouring ladles. Because the walls of the pouring ladle are much cooler than the furnace refractory lining, slag buildup is inevitable. The task of continually maintaining clean pouring ladles requires significant labor, and failure
