This project investigates Quality, productivity, and energy-saving improvement on heat treatment operation in the quenching process for manufacturing stabilizer bars. The main objectives are to study the productivity of manufacturing process of stabilizer bars and to volume ramp up by increasing production in per day batches which will result in high production rate for future usage. In this project, we have scope to utilize & increase our core mechanical field knowledge and give our contribution to industry to achieve industries’ objectives and goals. A stabilizer bar (roll bar, anti-sway bar, sway bar, anti-roll bar) is a part of many automobile suspensions that helps reduce the body roll of a vehicle during fast cornering or over road irregularities. For that rapid cooling process is carried out by Quenching process, Quenching involves the rapid cooling of a metal to adjust the mechanical properties of its original state. Steels with martensitic structure are often used in applications when the workpiece must be highly resistant to deformation, such as the cutting edge of blades. This is very efficient. To get a grip on why oil is a popular quenchant, it’s important to understand what happens in a quench. The succession of heating and then quickly cooling parts via quenching is a way to achieve added hardness to a part that otherwise wouldn’t have been possible. The heating causes changes in the crystalline structure of a metal part’s surface; the rapid cooling “freezes” those changes in place and makes the surface harder. This project also covers the detailed examination of quenching oil, which is used by the industry in cooling process. While there are many different types of oil used in quenching, two commonly used oils are fast and hot oil. Tube and shell type heat exchanger which heat is exchanged by two fluids in which one fluid is in the tube and other is in the shell (around the tubes). It is the most common type of heat exchangers in oil refineries and other large chemical processes and is suitable for higher pressure applications. The design of a plate heat exchanger (PHE) comprises several heat transfers plates. Held by a fixed plate and a loose pressure plate to form a complete unit. Each heat transfer plate has a gasket arrangement, providing two separate channel systems. A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. Project helped us study different parameters about tube and shell heat exchanger and plate type heat exchanger. Project studies the different parameters, materials, and specification used for manufacturing of sway bars. Research done during this project gives detailed analysis of methodology for manufacturing on sway bars. In this project, we have utilized & increased our core mechanical field knowledge. Detailed structure analysis of heat exchanger and quenching process is provided in this research
