use of ingot furnace slag

Air Pollution Aspects of Brass and Bronze Smelting and ...

----- The use of slag covers on the melt is generally desirable in all types of furnaces. A thick layer is not desirable, since it will re- duce heat transfer to the melt in direct-fired furnaces. Maintaining the cover between 1/4 and 1/2 inch, depending on the type of alloy and the furnace …

Effective Electroslag Remelting of Superalloys

ables such as melt mode, power level, slag chemistry and furnace atmosphere for various types of superalloy are reviewed and discussed. From the pro- cessing viewpoint, the differences between molten and solid slag starting are discussed as well as the effects of ingot structure and ingot surface

Gold Smelting & Refining Process

Gold and silver form an alloy that is heavier than the slag and sinks to the bottom of the furnace. Once the smelting is complete, the slag is removed and the precious metals are casted in ingots. The slag contains gold and silver and must be reprocessed in order to minimize the losses of precious metals.

Innovative Ground Improvement Technique for Utilization of ...

from these billets/ ingots, the steel slag is the waste generated. From ingot/ billets, about 20% steel is wasted. From these 20% actually 1% will be the finer slag and 1% lumps of steel that will be considered none of use. The steel lumps again mixed as a scrap material in the process of manufacturing of steel. About 18% of slag by weight is

Sand For Concrete From Steel Mills Induction Furnace Waste ...

In making mild steel ingot scrap to sponge iron is fed into the induction furnace which produces large quantity of slag. For example Kotdwar a small town of Uttarakhand Steel Mills induction furnances alone generates 15,000 tonnes of slag per year and about 1,50,000 tonnes of slag is lying as dump around this city posing an environmental problem.

ElectroSlag Remelting Furnaces - Consarc

Consarc can also provide a slag melting furnace with the ESR system that gives "hot" (liquid) slag start capability. This is most useful in situations where humidity and moisture are concerns, as well as in locations where sourcing of prefused slag is problematic. Consarc is the only ESR furnace supplier that designs and builds our own ...

US4350324A - Method of removal of slag deposits from the ...

Slag deposited on the bottom of a steel making furnace, especially a soaking pit for steel ingots, is difficult to remove. To enable this to be done while the furnace is hot, it is now proposed to supply a substance, e.g. ferro-silicon, which lowers the melting point of the slag, and a substance which reacts exothermically to initiate melting of the slag.

Thermodynamic calculation on the smelting slag of direct ...

12%Thermodynamic calculation on the smelting slag of direct recycling of electric arc furnace stainless steelmaking dust was presented. An induction furnace was used to simulate electric arc furnace smelting to recover the metals from the dust. The elements of iron, chromium and nickel in the ingot and the components of metal oxides in the slag were analyzed. The …

Slag inclusions - GIESSEREILEXIKON.COM

Reverse ingot segregation; Slag inclusions . As, in most cases, this defect is related to furnace or melt treatment slag it can occur in all casting materials, independent of the molding or casting process. This defect is often observed on casting surfaces on top in the mold, cores, and protruding mold sections. These non-metallic inclusions ...

Slag Furnace - Feed The Beast Wiki

The Slag Furnace is a block added by Factorization.It works similarly to the vanilla furnace, but has an extra output slot. It also uses twice the fuel. For most ores, it will produce an ingot with a low (20%) chance of making two instead of one, and also some Stone. Silver Ore will make Silver Ingots and Lead Ingots.Silver is used for Mirrors, which are needed to make Factorization Charge ...

Ingot, Billet and Slab - Eisen Group

Ingot: The ingot has a trapezoidal surface with a maximum length of 2 m in each branch. The appearance of the bars makes them easy to transport. Billet: The billet is longer than the ingot and has a circular or square surface with a width of less than 15 cm or …

Steel - Manufacturing Processes - Oxygen, Ingot, Hearth ...

The furnace ladle is first tipped to remove slag and then rotated to pour molten steel into a ladle. The speed and efficiency of the oxygen process has had a significant impact on the steel industry. An oxygen converter can produce a heat of quality steel in 30-45 minutes. ... Ingots may be square, rectangular, or round and weigh anywhere from ...

TREND AND APPLICATION OF MODERN METHODS IN INGOT …

Keywords: ingots, casting ladle, mould, casting pit 1. INTRODUCTION Casting is a final metallurgical operation in steel metallurgy. After the melting in primary furnace (BOF, EAF), steel is tapped in steel ladle, treated on secondary furnace (ladle furnace) and finally sent for ingot casting.

Casting Aluminum Ingots - Instructables

This caused more slag which means less ingot. Realistically, I think this furnace set up could be good to melt about 2 to 3 pounds of cans at a time. Then the ash would need to be cleaned out after that, but thats only if the paint can has not burned though.

SOME ASPECTS OF THE PRODUCTION OF FERROCHROME …

The latter slag type is presented in Figure 5 and Figure 6. Fluxing to produce the required slag composition was carried out using either silica or a combination of silica and lime (in the form of burnt lime or limestone). The resulting ternary slag contained in mass percent about 30-40% MgO, 30-40% Al2O3 and 20-30% SiO2. In the quaternary slag ...
