Cranes with electromagnetic lifting devices pick up charge materials from holding areas and move them to a weighing hopper or other charge makeup equipment. Used in this way they are ideal. They are not ideal when used to charge induction furnaces directly since the diameter of the magnet must not be larger than the diameter of the furnace opening.
Oct 01, 2014· These furnaces use induction heating to produce heat, which is a rather clean, energy-efficient way of producing heat. Therefore, no harmful pollutants are released during the melting process, and induction heating spreads throughout the furnace efficiently allow the heat to be absorbed by scrap in an efficient way.
Apr 01, 2016· iron ore. SO 2, CO emission and the charging of DRI/HBI aims at avoiding the . synthetic cast iron can be produced in direct current arc furnace using the scrap
Scrap Charging In Induction Furnace. Scrap charging device for induction furnace electric arc furnace wikipedia, the free encyclopedia 5432 f arc furnaces differ from induction furnaces in that ore
Apr 07, 2013· But as most Induction Furnaces are open-topped, it is difficult to capture and utilize their waste heat. The process requires the usage of External Heating Source. Several methods can be adapted for preheating Scrap and DRI for Induction Furnaces.© R.A.D.E INITIATIVE 2013 [email protected] 4.
The number of charge buckets of scrap needed to produce a heat of steel is dependent mainly on the scrap density and the volume of the furnace. Modern furnaces are designed to operate with a minimum of back-charges. This is advantageous since the charging time is a dead time (furnace with no power-on and hence not melting).
In an electric induction furnace savings can be as high as 50 kWh/t of molten metal. In a cupola furnace savings of up to 50 kg coke/t of molten metal can be achieved. • The higher bulk density of pig iron relative to scrap means lower storage space re-quirements, less handling during charge make-up, fewer charge buckets and lower charging time.
1) Raw Material: Induction Furnaces are using Steel melting scrap, Sponge Iron & Pig Iron/Cast Irons. On an average the ratio of these items is 40% sponge Ir on + 10% Cast Irons or Pi g Iron. The
The reduction of the iron oxide in the ore is endothermic and higher amounts of hot metal and lower amounts of scrap are required when iron ore is used for cooling. Iron ores are to be charged early in the blow when the carbon content in the liquid bath is high so as to effectively reduce the iron oxide in the iron ore.
metallurgical process consists in the reduction of iron ore. In the blast furnace, cast iron is produced then it is converted into steel by blowing oxygen in the converter (BOF). The electric arc furnace cycle is based on the melting of metal scrap. The manufacturing
Sep 18, 2013· Better charging: HBI is compact and the briquettes are easy to feed into the furnace. In contrast, scrap is most unwieldy and sometimes needs cutting down, an expensive process. It also frequently breaks the electrodes. By using HBI both the availability of the smelting furnace and the safety of employees while charging can be increased.
Fine-grained iron-containing substances dusts, sludges, mill scale, sponge iron or ore fines are transformed into high-temperature-resistant self-reducing agglomerates. These so-called C-bricks can be melted together with scrap or bear in a shaft furnace to pig iron in blast furnace quality.
Induction Furnace Charger Induction Furnace Charger, Vibrating Furnace Charger for Sponge Iron and Shredded Scrap Furnace Charger is a type of equipment designed to charge an induction furnace with tattered scrap or sponge iron, safely and efficiently. It also helps in improving and enhancing the security and productivity of plant.
Experiment of the technique using metalized ore-coal pellets in the furnace-charge were carried out in coreless induction furnace IST-1. This furnace is applied in a foundry shops of a mechanical plant to produce synthetic pig iron of SCh 40-60 and SCh 44-64 grades.
Upgrading of purchased scrap has been another way to increase raw material quality by controlling residuals, including sulfur, phosphorous, tin and copper. Several chemical approaches to remove copper that is physically associated with junked cars (shredded scrap, #2
In an electric induction furnace savings can be as high as 50 kWh/t of molten metal. In a cupola furnace savings of up to 50 kg coke/t of molten metal can be achieved. • The higher bulk density of pig iron relative to scrap means lower storage space re-quirements, less handling during charge make-up, fewer charge buckets and lower charging time.
Nov 12, 2013· For light scrap of Aluminum melting 600-625 kWh/ton require For Solid scrap of Aluminum melting 500-575 kWh/ton require For Steel melting 625 kWh/ton require. //electroheatinduction In this 300 kW induction furnace for steel making, the steel is molten and smooth, with exceptional consistency and clarity as shown by the stirring rod
Microstructures displayed by the thermally treated for 10 minutes at 1200° C (A), 1300° C (B), 1400° C (C), 1500° C (D) and for 20 minutes at 1500° C (E) samples.
Jul 05, 2018· The Induction Furnace is an advanced version of the Electric Furnace. It has the ability to process 2 stacks of items simultaneously. Doing so will also save 50% of the energy that would have been used had every stack been smelted by itself. Another feature of the Induction Furnace is

Induction Furnaces at the Cutting Edge. Electroheat Induction delivers the quality and efficiency you need for your induction furnaces, induction heating and hardening equipment, and induction welding equipment. Our products have applications in a variety of industries and specialties, including: Mining, forging, foundry and metal processing
This permits the charging of all furnaces by the same charging machine, crane, and rail system. Bulk materials, such as scrap, cold blast-furnace iron, ore, limestone, coke, and alloying agents, are charged through the furnace doors in small boxes of one- to two-cubic-metre capacity. The boxes are brought to the OHF on small railroad buggies
The furnace is completely drained to eliminate any chance that scrap containing moisture will be added to a molten-aluminum heel. The drawback to the batch process is that the presence of flux gives a thicker dross layer and entrains more metallic aluminum. A more versatile version of this furnace has a side well for charging scrap (Fig. 1).
