2016-8-24 The Blast Furnace is a vertical shaft of circular cross-section and stands approximately 40 m high (although the overall facility approaches 100 m). The vessel is internally lined with cooling elements and refractory bricks and blocks. Iron ore, coke and fluxes are charged into the furnace to produce molten iron and slag. The Blast Furnace operates continuously

2018-7-10 HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.

2019-4-15 A blast furnace (BF) produces liquid iron (hot metal) by the reduction of ore burden with reducing gases. The reducing gases are produced by the reaction of oxygen with coke and coal. This oxygen is part of enriched hot air blast which is blown and distributed at the bottom of the BF through the straight pipes, blowpipes and the tuyeres.

Most steel mills have tight control of coke ash and sulfur. Coke ash has a negative impact on blast furnace fuel consumption and stable blast furnace operation due to its catalytic effect on coke reactivity and its alkalis’ attack on the blast furnace lining, while coke sulfur increases blast furnace fuel consumption and reduces hot metal quality. Coke ash and sulfur can be related to coal ash and sulfur

The large scale database-based online modeling, called LOM, is a type of just-in-time modeling for blast furnace. In this paper, we propose a new type of LOM using a nonlinear local model to improve the performance of the long-term prediction. To estimate the parameter of the nonlinear local model, we use on-line Bayesian learning scheme with sequential Monte Carlo.

2016-1-29 The cold blast main is also equipped with a snort valve, usually located near the blast furnace which is opened when it is necessary to decrease the blast pressure rapidly. This discharges the cold blast air to the atmosphere and keeps a positive pressure on the cold blast line so that gas from the furnace cannot travel back to the air blower.

Internally the blast furnace is considered to consist of five discrete zones, see Fig. 17.2, through which all furnace gases and/or liquids must pass.The location, shape and extent of each zone is influenced by the properties of the material layers (relative thickness, etc.) and by the properties of the materials themselves. These factors interact to determine the flow and distribution of ...
