evaluation of lining cooling systems for blast furnace

International Journal of Soft Computing and Engineering

lining/cooling system of a blast furnace must be able to cope with the worst deviations one can expect during the campaign. For each and every blast furnace the conditions for which to design a refractory lining and cooling system are different. of lining material

Sidewall cooling would also assist in maintaining a slag freeze lining. Operating with a slag basicity within the 1.68 to 1.90 range should therefore not pose a severe risk. As the process will be operated on a semi-batch basis, the variation of the slag and alloy composition throughout the heat could potentially result in a material that is not compatible with the refractory lining.

MMK renovates blast furnace No. 2

The equipment for the cooling system of blast furnace No. 2 is supplied by the Luxembourg company Paul Wurth. Following its reconstruction, the new furnace will have non-lintel design. An important element of the reconstruction of MMK's blast furnace No.2 is the reconstruction of the casting beds with a system of closed gutters and the aspiration of the casting beds and charge feed.

Paul Worth to upgrade JSW blast furnace number 3

Blast furnace top gas cleaning will be ensured by a new axial cyclone and a modified wet gas cleaning system. Capacity extensions to stockhouse and cooling systems will also be necessary. The modernised blast furnace will have an inner volume of roughly 5,300m3, up 32%, an increased hearth diameter (from 13.2m to 15m) and 46 tuyeres (up from 36).

Methods of extending a blast

As before, the main trends in blast-furnace smelting in the Twenty-First Century are decreasing coke consumption, increasing furnace productivity, and lengthening of the furnace campaign. In the last few decades, the focus has increasingly been on extending the campaign through various technical, technological, and organizational measures. This article surveys the work done in these areas and

Blast furnace

Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide, having a stronger affinity for the oxygen in iron ore than iron does, reduces the iron to its elemental form. Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and

Steel

2021/5/5Basic oxygen steelmaking More than half the world's steel is produced in the basic oxygen process (BOP), which uses pure oxygen to convert a charge of liquid blast-furnace iron and scrap into steel. The basic oxygen furnace (BOF) is a refractory-lined, tiltable converter into which a vertically movable, water-cooled lance is inserted to blow oxygen through nozzles at supersonic velocity onto

BLAST FURNACE (BF)

Blast Furnace - An Introduction Blast Furnace is the focus of any integrated steel plant. Blast furnace is used to reduce the iron ore to iron. The charge, which consists of iron ore, coke and limestone etc. in the form of lumps and different ratios, is fed from the top.

Concrete

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, lime based cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual

Efficient cooling is required to balance the thermal load and associated wear of the inner lining of the furnace. Offered in combination with our copper and cast iron coolers for any zone of the blast furnace, our optimized primary and secondary cooling systems

Principles for Blast Furnace Refractory Lining Inspection

2021/4/9The typical campaign life of a modern blast furnace is 15 to 20 years, depending on the cooling and refractory design as a whole and the hearth area in particular. Hearth repairs and relinings are undoubtedly the most costly items for blast furnaces.

Model of Forming

Copper staves have been equipped on nearly all of BF (blast furnaces) with volume over than 1000 m3 in China since their introduction from abroad about more than 10 years ago. Because of short application and lack of experience, phenomena of thickened or naked of copper stave happen occasionally which influence production severely. So it is important to study the model of forming-accretion on

Failure characterization of the interface between concrete

Concrete structures are severely susceptible to degradation as a result of mechanical or environmental processes. In most cases, retrofit is the only available option because reconstruction of the deteriorated structure is neither a feasible nor financially practical option. The overall performance of a repaired structure is highly dependent on the properties of its interface, which is the

MMK plans to reconstruct its blast furnace No. 2 next year

As part of the modernisation process, MMK plans to dismantle and completely replace all parts of the old furnace, as well as to replace the cooling system. Equipment for the new cooling system will be supplied by the Luxembourg company Paul Wurth, which has been selected following the results of a tender which required the cooling systems presented to have horizontal cooling elements.
