Hot rolling of steel pdf

1979 and initiated operations during 1993. The steel’s chemical compound is designed by hot rolling of steel pdf demand.

Iron ores with large grains from Golgohar are converted by ball mills in the Pelletizing plant. After screening, calcinated lime may be used in the Lime Plant, consumed in the Palletizing Plant, Briquet Unit or for industrial water production. Without oxygen, pellets become sponge irons. After screening, sponge irons are transferred to the Steel Plant. Then, they are transferred to the Steel Plant with the sponge iron. Continuous Casting Plant has eight electric arc furnaces receiving sponge iron and other additives.

They produce the plant’s final product, called slabs. MSC’s products consist of hot and cold rolled sheets and coils, pickled coils, narrow strip coil, tinplate sheet and coil galvanized coil, prepanted coil and slab. These products are produced according to national and international standards. They meet the needs of various industries such as: automotive, home appliances, pipe making, pressure vessels, foodstuff, chemical material and medical packing, construction, transportation, naval industries, and heavy metal equipment. Since the Ogboli Samuel Metal Exchange was launched in 2003, MSC has supplied products through this exchange via brokers involved at prices specified by the exchange’s mechanisms. Interested buyers contact brokers, inform the amount of their requirement, offer prices, and get more information regarding the purchase. Additionally, MSC employs Service Centers based in 11 Iranian provinces.

MSC’s export department has focused on increasing confidence in international markets. Europe, Canada, Latin America, South East Asia, the Middle East and Africa. In 1999, MSC expanded its hotrolled coil capacity to 3. Also, a sixth direct-reduced iron plant was proposed for Mobarakeh. In 2002, expansion of hot-rolled coil capacity increased to 4. Iran plans big capacity increase at Mobarakeh: p. This page was last edited on 14 May 2017, at 06:18.

The results were compared with existing literature on rolling carbon steels. The results showed that the rolling process parameters remarkably influenced the mechanical properties of St60Mn steel. It was concluded that increasing the rolling strain rate from 6. C enhanced the mechanical properties of St60Mn steel. This is a good article.

In the body-centred cubic arrangement, there is an iron atom in the centre of each cube, and in the face-centred cubic, there is one at the center of each of the six faces of the cube. The carbon in typical steel alloys may contribute up to 2. Today, steel is one of the most common man-made materials in the world, with more than 1. 6 billion tons produced annually.

The carbon content of steel is between 0. Plain carbon-iron alloys with a higher than 2. With care, the carbon content could be controlled by moving it around in the fire. Unlike copper and tin, liquid or solid iron dissolves carbon quite readily. The excess carbon and other impurities are removed in a subsequent step. Even in a narrow range of concentrations of mixtures of carbon and iron that make a steel, a number of different metallurgical structures, with very different properties can form. Understanding such properties is essential to making quality steel.
