Born in 1940 at Matunga, Mumbai (Bombay, at that time), this is my 71st year in the city. I have witnessed at first hand the changes, both technological and other, that have taken place in the city and the country over these seven decades. I recall that in the early years one had to have your bicycle registered and to have a licence if you possessed a radio. I often shared a cup of tea with bread and Polson butter at the Irani restaurant opposite Don Bosco High School with the beat policeman (‘havaldar’), the same one who later went out of his way to safely escort me home during the 1947 partition-related riots. Yes, we have moved on since those days. Then, we had the Russian politicians, Bulganin and Khrushchev, travelling in an “open car” and we stood outside our school waving flags. And, at Khodadad Circle (Dadar TT) they were showered with ‘pedas’ from the overhead welcome arch built by Damodar Sweet House as their car turned towards Tilak Bridge. I was even allowed to be 20 feet close to the US First Lady, Jacqueline Kennedy, when she visited the Ganges at Varanasi. Yes, those were days when political stalwarts moved about freely without fear and minimum security. Try telling all of this to the present generation - they think you have ‘lost it’.
In the fifties, Greater Mumbai’s population was about 1% of the country’s. Today, the population of the Mumbai Metropolitan Region is close to 3%. Yes, many things have changed, many for the better, others for the worse. Steel Reinforcement falls in the latter category. I believe that in this field, for every step forward, we have taken two steps back. In the name of progress the steel industry has only succeeded in totally confusing the civil and structural engineers about steel rebars. This opinion is based on my continuous interaction with them over the last three decades - especially since my 2003 meeting with one of India’s most renowned structural engineers, the late Mr. Ramesh N. Raikar who was at that time President of the American Concrete Institute - India Chapter. Unfortunately, in my personal view, over the past few decades the IS Code for rebars has only worsened matters and added to the confusion. Through this piece, I hope to clear many of the doubts that exist in the minds of the civil engineering fraternity by addressing some of the myths about rebars and the real status. There are quite a few myths about rebars which have been thrust upon them and this is doing India no good. Let me try to take up the most common of them - based on my continuous interaction with the civil engineering fraternity.

The evolution of preheating and the importance of hot heel in supersized Consteel® systems
By Mario Marcozzi, Marta Guzzon, Tenova SpA, Italy

The first Consteel® system was started-up in Charlotte, NC in 1989; since then 39 other installations have been purchased worldwide. None of those installations have been dismantled or replaced with another technology; no other innovative melting technologies can demonstrate the same track record. The first Consteel® systems were mainly commissioned in the US, but during the course of its history, the Consteel idea has expanded at an impressive rate into Asia including; China, Vietnam, Thailand, Japan and South Korea. In order to satisfy the productivity requirements of the Asian market of the last decade, the Consteel design focused on the heat size and the continuous charge function, more than the preheating function, achieving particularly high production rates. Lately the development of Consteel® technology is focusing once again on the preheating function, in order to accomplish the energy savings and environmental requirements of western countries. The high hot heel around 50% of the heat size is a common characteristic of the new Consteel Systems designs. This paper describes the reasons why the Hot Heel is a fundamental pillar of the Consteel process, providing process details and technological peculiarities, in particular for the large heat size Consteel applications, as well as the new Consteel Evolution™ concept.
