AIM To describe a new toxic inhalation syndrome in blast furnace workers. METHODS Fourteen workers developed acute respiratory symptoms shortly after exposure to "air blast" from blast furnace tuyeres. These included chest tightness, dyspnoea, rigors, and diaphoresis. Chest radiographs showed pulmonary infiltrates, and lung function a restrictive abnormality. This report includes a descriptio...

This paper presents the application of DSTATCOM in a distribution network with induction furnace load. Induction furnace is one of the common types of load used in industries like the steel industry. The problem with the induction furnace load is the generation of appreciable amount of harmonic distortion. This distortion results due to the design and operation of the induction furnace. This ha...

Optimisation and improved control of the annealing furnace on a continuous galvanising line was investigated by the construction of a series of mathematical models to predict furnace and strip temperature and strip recrystallisation under both steady and transient states. A modelling approach is followed due to the very poor measurability of temperatures inside the furnace, affected by strong r...

This article studies the transient heat conduction in a slab when passing through various sections of the furnace, and focuses on the thickness of the scale layer formed on the slab. The transient heat conduction behavior of a slab in various sections of the heating furnace is analyzed using the Laplace transformation method, including the pre-heating zone, the first heating zone, the second he...

An explicit equation leading to a method for improving furnace efficiency is presented. This equation is dimensionless and can be applied to furnaces of any size and fuel type for the purposes of comparison. The implications for current furnace design are discussed. Currently the technique most commonly used to reduce energy consumption in galvanizing furnaces is to increase burner turndown. Th...

In this paper the influence of the moisture content on the flow characteristics of blast furnace dust is investigated. The flowability of granular material is essential for the design and operation of dust separators, transport equipment and storage silos. Two blast furnace dust samples from different blast furnaces were investigated. The moisture content was adapted for measurement with the sh...

a mathematical model of a continuous reheating furnace has been developed to identify the design and operating parameters that significantly affect furnace performance. in this study, the furnace is modeled 3 dimensionally and themonte carlomethod is used to find the overall absorption factor. the overall absorption factor is then used to calculate the energy balance for furnace walls, the gas,...

To further improve the metallurgical quality of electroslag remelting, remove large inclusions in ingot and refine solidification structure ingot, an remelting furnace with electromagnetic stirring was designed, influence different magnetic induction intensities on GCr15 studied. Inclusions sizes types were analyzed by ASPEX scanning electron microscope, morphology composition observed a JSM-65...

It is critical for the iron and steel industry to achieve green transformation development by effectively utilizing abundant biomass resources in blast furnace ironmaking. In this paper, four types of typical were carbonized upgraded using hydrothermal carbonization (HTC) method, metallurgical performance prepared hydrochar injection was systematically tested. The results show that HTC treatmen...
