slag strongly depleted in heavy metals is converted into a hydraulically active phase similar to typical cement components. This enables its use in the cement industry where slags from pig iron production – so-called blast furnace slags – have already been extensively used. The project reatment of the high-grade steel slag by
chemicals & liquid fuel. Iron foundry slag may be highly reactive if calcium carbide is used to desulphurise the iron (A.K. Anand5, 2008). HEALTH HAZARDS DUE TO HEAVY METALS Heavy metals pollution either directly or indirectly entering the food chain are becoming an increasing threat to health. Mercury metal is toxic for living beings.

• The Grede Foundry plant in Michigan built a state-of-the-art employee training facility, learning center and lunchroom using concrete blocks made from foundry slag. AFS Headquarters Washington Office 505 State Street 900 2nd St., N.E. — Suite 109 Des Plaines, .
Foundry sands are high quality silica sands used to make the molds for casting the parts. The sand is reused until it is physically degraded, at which point it is removed from the sand supply. Foundry slag is composed of fluxing agents and impurities removed from the molten metal prior to casting.
This project was conducted in a local foundry plant specialized in producing ductile and gray iron castings for automotive, truck and other heavy equipment applications. In this project, the author worked with six other employees in the plant to study and improve the induction melting process in the Melt Department. Problem Statement
GUIDE TO MANAGING RISKS ASSOCIATED WITH FOUNDRY WORK 4 APRIL 2013 1.3 How to manage health and safety risks A person conducting a business or undertaking must manage risks associated with hazardous chemicals, plant, hazardous manual tasks, noise and electrical risks.
Steel slag is a byproduct of iron and steel production by the metallurgical industries. Annually, 21 million tons of steel slag (SS) is produced in the United States. Most of SS is landfilled, which represents a significant economic loss and a waste of valuable land space. Steel slag has great potential for the construction of highway
LADLES & SLAG POTS Description In the metallurgical and melting fields, a ladle is a vessel used to transport high temperature metal or pour out molten metals. Usually it has three different function types, for example, casting ladle, transfer ladle, treatment ladle. .
concrete slab panels produced using industrial by-products - foundry sand, as a partial replacement of fine aggregate, and ground granulated blast furnace slag as a cement admixture. Foundry sand was substituted for manufactured sand in levels 0%, 10%, 20%, 30%, 40% and 50%, while granulated blast furnace slag

C) BASIS & PRESUMPTIONS . 1. the scheme has been prepare3d on the basis of 75% efficiency on single shift considering 25 working days in a month. 2. the rate of interest in the scheme has been worked out on the basis of 14% on an average; however this figure is likely to vary depending on the financial ...
Iron foundry slag is a material similar to steel slag that is a byproduct of iron casting. Iron foundry slag is landfilled in large quantities by industrialized nations that produce cast iron products. Consequently, iron foundry slags can be obtained for little or no cost, and finding beneficial uses for .
Slag/Dross Inclusion Elimination Case Histories . Foundry A melts both gray and ductile iron in several large channel and coreless melting furnaces. Foundry A melts roughly 160 tons per day of both gray and ductile iron, producing a broad range of castings weighing from 50 lbs to several tons.
Abstract: This research deals with the formulation and evaluation of strength properties of Portland slag cement using local foundry slag. The relative substitution of about 10 to 50% of ordinary Portland cement for slag as an alternative cement (slag cement) to the commonly available but highly expensive ordinary Portland cement in Nigeria market.

A foundry is a factory that produces metal castings. Metals are cast into shapes by melting them into a liquid, pouring the metal into a mold, and removing the mold material after the metal has solidified as it cools. The most common metals processed are aluminium and cast iron.
an attractive and useful project which has been made in the foundry area. Practical foundry projects and techniques are divided into six areas in the following pages. Descriptive pictures are conveniently located at the end of each project unit. Periodic reference to these pictures will aid the reader in
refractory furnace linings and quality foundry coke are used, the amount of slag generated would increase as these parameters directly impact on slag generation and its quality [8-10]. Currently, slag produced is disposed off on the foundry site floor. However, there is a great demand for
foundry industry. Owing to slag – free tapping, steelmaking slag always contains a portion of solid metal – raw steel. Utilization of this metallic part in scrap charge is normal practice. Remaining demetallized slag is utilized mostly in road building industry, but benefits of demetallized slag recycling into steelmaking furnace are ...
