Manganese coatings are excellent for the cathodic protection of steel against corrosion. Although manganese is more electrochemically active than widely used protective zinc, exceptional resistance in neutral and basic media determined by film insoluble corrosion products, which forms on surface greatly suppresses its further It known that electrodeposition process Mn from sulphate electrolytes...

In this work, the effects of scale on thermal behavior of the slab in a walking-beam type reheating furnace is studied by considering scale formation and growth in a furnace environment. Also, mathematical heat transfer model to predict the thermal radiation in a complex shaped reheating furnace with slab and skid buttons is developed with combined nongray WSGGM and blocked-off solution procedu...

Ethylene cracking furnace system is the heart of ethylene production. It can process different raw materials in the pipe group of each furnace and can produce the main chemical products like ethylene, propylene and ethane. In the real world ethylene plant, there are two operation modes in the furnace system, one has a backup furnace in the system and the other is with all the furnaces available...

The aim of the current work was to analyse impact salt bath nitriding on behavior tribological characteristics and surface microstructures AISI 316L stainless steels. Nitriding carried out at 580°C for 10 h. tribological, structural before after compared. microstructures, characteristics, as well its hardness, were investigated using optical microscopy (OM), X-ray diffractometer (XRD), profilom...

The harmful effects of salt on the skin were first described by Paracelsus (1493-1541, see Schwartz, Tulipan, and Peck, 1947), and there have been accounts since confirming this clinical observation in many industries. Ulcers of the legs occur in salt-miners (Ramazzini, 1700). Salt-water boils are found in shipwrecked sailors and deep-sea fishermen (Critchley, 1943); dock labourers carrying bag...

In the present work the recrystallization behavior of deep drawing grade Al-killed low carbon steel sheets produced by Mobarakeh Steel Plant (MSP) has been studied. Salt bath isothermal annealing has b...

the continuous improvement of eaf performance is crucial for the increase in productivity and cost effectiveness and to render an environmental friendly process. rhi supports these targets by providing a diverse range of refractory and process solutions. chemical energy in practical operation by injection of gaseous media like oxygen and natural gas, and solid materials like carbon have become ...
