China goes quality
![]()
„It's unwise to pay too much, but it's worse to pay too little. When you pay too much, you lose a little money — that is all. When you pay too little, you sometimes lose everything, because the thing you bought was incapable of doing the thing it was bought to do. The common law of business balance prohibits paying a little and getting a lot — it can't be done. If you deal with the lowest bidder, it is well to add something for the risk you run, and if you do that you will have enough to pay for something better.“
attributed to John Ruskin as Common Law of Business Balance

Germans remember well and British are supposed to, too: the effect of a seal of quality!
As of August 23rd, 1887, Britains happened to implement their Merchandise Marks Act, prescribing that the country of origin must be stamped on any imported goods. Thus they especially tried to protect themselves against cheap products from Germany which, in those days, was developing into an industrialised country. The Germans then used to reproduce British high-priced goods on a level, which the islanders denoted „bad & cheap“. Anyway, in those days, Germans had to work longer and at lower wages, compared to Britains. The latter neither liked the rip-offs, nor the associated underselling. Against this background, the label „Made in Germany“ was born, originally intended to attest poor quality and to safeguard the good reputation of British genuines.

However, German products capturing the British market, more and more turned out to be of proper quality. Thus, backfiring primary intention, British consumers deliberately chose German commodities.

Principles of pressurised-electroslag-remelting (P-ESR) and hot forming of high-nitrogen steels
High nitrogen steels are commonly known for their excellent mechanical properties, i.e. strength and corrosion resistance.
A state-of-the-art production routine is P-ESR melting (pressurised electro slag remelting). It is possible to manufacture both, austenitic as well as martensitic steels suitable for forging and hot rolling. Some basic knowledge of the material peculiarities is mandatory to avoid any potential issues during plastic deformation.
The following paper provides an overview of the manufacturing of HNS as well

Improving the utilization in bar rolling
With increasing cost for energy, manpower and utilities, it becomes essential to keep a high utilization of bar and wire rod mills. Especially since the capital cost for a mill is strongly dependent on the output, and thus for a given mill, the utili-zation influences the capital cost.
It is partly possible to affect the utilization by internal measures, but market conditions strongly influence the possibilities to utilize the mills, which must be run differently

Reduction of mill scale generated by steel processing
Mill scale is one of the by-products produced during steel processing and its specific production is considerably high representing about 19-40 kg/t of hot rolled product, depending on the deformation technology used. The global production of steel during 2008 was 1125 million t and the corresponding mill scale produced is estimated to be 33 million t on average. On the other hand, mill scale is

Latest trends for building up a competitive supply chain in future-oriented steelmaking
Excerpt from a presentation to 7th Chinese Iron and Steel Industry Chain Strategy Development and Investment Summit, Beijing, Nov. 18-21, 2009
What is it that makes steel industry competitive in our days? is the crucial question governing every consideration and decision of our top managers. The benchmark is not only set by the financial challenge, but also by environmental issues, product quality and value. This

Influence of coking time on coke quality from non-recovery vibro-compacting coke ovens
Coke quality depends on the quality of coal or its blend, coking parameters and pre-carbonisation techniques, if any. JSW Steel has adopted vibro-compaction pre-carbonisation technique, along with non-recovery ovens, having a capacity to produce 1.2 million t/a of coke. Coking conditions are determined majorily by coking time and oven temperatures, etc. Coking time is the most important parameter of coking conditions and plays a significant
