Introduction
Eco-friendly natural refrigerants as alternative refrigerants

Due to toxicity of NH3, flammability of hydrocarbons, and high pressure and low COP of CO2, blends are more effective.

CO2 and HC mixtures have superior heat transfer properties with reduced cycle pressure and flammabilit ....etc

LD#2 Department Here desulfurization of the hot metal is carried out and the hot metal is sent to vessel unit where it is converted in to steel in Basic Oxygen Furnaces. Main material handling jobs are:

Hot Metal handling : Torpedoes of 220/320 t capacity bring hot metal from blast furnaces. These are unloaded in hot metal ladles (155 t) at the torpedo unloading pit.

Desulfurization Unit : desulphurization by CaC2 & Mg powder injection, ....etc

Load sensing hydraulic system
Load sensing hydraulic systems conserve energy by generating only the fluid flow demanded by the system and at a pressure only slightly greater than the highest load pressure of the system. the variable displacement pump can go to its maximum displacement setting with the excess fluid generated by Optimizing the operating characteristics of the system . It includes a flow control valve connected to a directional control valve .
It has has an operating position such that fluid exhausted from a hydraulic ja ....etc

The uniaxial extensional viscosity is a fundamental material property of a fluid which characterizes the resistance of a material to stretching deformations. For microstructured fluids, this extensional viscosity is a function of both the rate of deformation and the total strain accumulated. Some of the most common manifestations of extensional viscosity effects in complex fluids are the dramatic changes they have on the lifetime of a fluid thread undergoing capillary breakup. In a pinching thread, viscous, inertial and elastic forces can all r ....etc
