Tundish Powder During continuous casting of steel, liquid steel is poured from ladle to tundish where its flow is divided to each strand of the continuous casting machine. The role of the tundish is not only to act as the dispenser of the liquid steel, but also it is the last major reactor where refining …
Read MoreBelt Conveyor Idlers Belt conveyor idlers are the rollers which are used at certain spacing for supporting the active as well as return side of the conveyor belt. Accurately made, rigidly installed and well maintained idlers are very important for smooth and efficient running of a belt conveyor. Important requirements for idlers are proper support …
Read MoreLow Alloy Steels Alloying elements are added in the steels for various reasons which include improved corrosion resistance and / or improved mechanical properties at low or elevated temperatures. Alloying elements are also used to improve the hardenability of quenched and tempered steel. The term ‘alloy steel’ is used for those steels which have got …
Read MoreHot Work Die Steel Hot work die steels find their use in hot forming processes. Hot forming processes are among the oldest and most important metal forming processes and accounts for a large percentage of metal products. Hot metal forming consists of a forming process either by plastic deformation or solidification where the metal is …
Read MoreHigh Speed Steels High speed steels forms a special class of highly alloyed tool steels, combining properties such as high hot hardness and high wear resistance. These are so named mainly because of their ability to machine materials at high cutting speeds. These steels have been widely adopted as the most basic material for cutting …
Read MoreCladding of steels There are several industries, such as, chemical and fertilizer industries, nuclear and steam power plants, food processing, and petrochemical industries etc., where corrosive environments are inevitable. Several process equipment / engineering components are exposed to the corrosive environment in these industries which reduces their service life. In such applications, materials (like duplex …
Read MoreFinished Steel Products Produced in Steel Plants Steel plants produce a large number of finished steel products. The steel products are produced in mild steel, in plain carbon steel, in micro alloy steel, in low alloy steel, or in high alloy steel quality. These steel products can be broadly divided into four categories namely (i) …
Read MoreHydrogen Fuel for Future Economy Hydrogen is the fuel of the future. It is an energy carrier which can transform the present fossil-fuel dependent economy into a hydrogen economy and which can provide an emission-free fuel. It can be used in internal combustion engines or fuel cells producing virtually no greenhouse gas (GHG) emissions when …
Read MoreHot Blast Stove Refractories Hot blast stove is used to preheat air used in the blast furnace. It works as a counter-current regenerative heat exchanger. It consists of tall, cylindrical steel structures lined with different kinds of refractories and almost completely filled with checker bricks where heat is stored and then transferred to the fresh …
Read MoreBlast Furnace Valves Blast furnace (BF) process needs large quantity and variety of valves. During ironmaking in the BF, a number of gases, utilities, and dust are to be handled. These include (i) combustion gas, combustion air, and waste flue gas in hot blast stoves, (ii) cold air blast, oxygen, and hot air blast, (iii) …
