A Feasibility Study to Convert Steel Industry Solid Waste into a Red Oxide Primer

Satyanarayana SV, Ahmed H Al-Balushil

The steel industries generate a high volume of solid waste each year. The disposal of solid waste is a Hercules task for steel industry management. The solid waste contains heavy metals like iron, chromium, lead, zinc and toxic chemical compounds. The solid waste disposal contributes for ground water pollution and soil pollution. The steel industry solid waste contains a high percentage of iron oxide more than 12%. The aim of this project is to convert steel industry solid waste into a red oxide primer. The solid waste samples are collected from a local steel industry. The samples are crushed and passed through a 53 micron mesh to get fine powder. The powder is mixed with Long oil alkyd, calcium carbonate and Butanol. The mixture mixed intensively by the help of a wet grinder until it gets adhering properties and become as a primer. The adhesive properties of the primer is tested by painting on a metal surface and after drying the primer on the metal surface and tested by the peeling method to check the strength of the primer. The primer viscosity modified by adding turpentine oil. The red oxide primer used as a dielectric or pre-coating on iron structure. It was observed that the red oxide produced by using steel industry solid waste is at par with commercially available red-oxide primer. The red oxide primer production from the steel industry sludge is technically feasible and economically viable.
