If not, remove all the combustible material to a safe distance of at least 6m. 2. packed into a 3/8" (17.2 x 2 dia.) 2. Name of the Work: LANCING JOBS IN LD AREA OF SMS To The Deputy General Manager I/c Works Contracts Department Visakhapatnam Steel Plant Visakhapatnam - 530 031 Sirs, With reference to the Notice Inviting Tender, I/We have gone through the tender documents issued to us. Oxygen Lancing Pipe for Steel Furnaces and Ferro Alloys Plants, Steel Pipes for various industrial and structural purposes. The process is based on the principle that the iron pipe burns at approx. More recently, oxygen l… Metallurgical coal – or coking coal – is a vital ingredient in the steel making process. JSW is also the first company to manufacture high-strength and advanced high-end steel products for its automotive segments. High quality steels such as stainless steel, high alloy steels, and tool steels are generally made in an EAF. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel. modern, sustainable iron and steel technology within human activity in coexistence with environment on a global scale. The oxygen valve is opened further, and shall be fully open in about 1 to 2 cm cutting depth. The system was installed in the fall of 2016. An oxyfuel gas torch is used to bring the cutting end of the lance to white heat, and then the oxygen valve is slowly opened to start O2 flow, and initiate the burning operation of the packed lance. This ensures excellent plant availability plus best production results. steel (or more) that may stand alone in the structure or that is one of many pieces in an assembly or shipping piece. Oxygen lancing and carbon additions are used to make a foaming slag which yields better energy input from the arcs and improves dephosphorization. During the production of primary steel products, some secondary products and by products are also produced which are to be sold. Moreover, the main part of the generated heat is removed with the ejected lava. in the steel plant & design , implement the best suited ... operation, Lower bursting pressure (5-8 kg/cm2), use ... & lancing practices etc also influence the plug performance. Preparation of the charge bucket is an important operation, not only to ensure proper melt-in chemistry but also to ensure good melting conditions. S R78 C (iv) in active mixers'2 by lancing and jetting 02 (v) in a basic OH furnace functioning as a pretreatment furnace. The systems, for two continuous casting machines, provide tundish temperature measurement, O2 content measurement and steel sampling as well as oxygen lancing and tundish powder handling. Please ensure that any lancing operation is carried out by experienced personnel only and that the following minimum safety precautions are taken. 449 Int. The ejected slag, therefore, has to be blown off continuously. The predicted total costing shown is not meant to represent an actual cost for any real steel company. Basic oxygen steelmaking, also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. By using sites operated by REINGUSS, s.r.o., you agree to the use of cookies to help us provide better service Hi all ! A fuel gas is not required for the process itself, it may, however, be used in a welding torch to heat the cutting end of the lance to ignition temperature.
