A356 aluminum cast alloy was employed for experiment material. The chemical compositions of alloy are 7.5% Si, 0.53% Mg and 0.05% Be with aluminum being balance. A burden of 40Kg, 160kg and 280kg was melted respectively in the electric resistance furnace and the temperature of the melt was maintained as 720C for use.
Again, the construction of electric furnace s may often be exceedingly crude and simple; in the carborundum furnace, for example, the outer walls are of loosely piled bricks, and in one type of furnace the charge is simply heaped on the ground around the carbon resistance used for heating, without containing-walls of any kind.
Electric Furnace. Smelting in the electric furnace is similar to that in the reverberatory furnace except that no external fuel is used. The heat necessary for melting is generated by the resistance of the slag to the passage of a high amperage current between heavy carbon electrodes immersed in the slag.
Copper Melting Machine, Copper Melting Machine . Alibaba offers 5,488 copper melting machine products.

SUPER resistance elements that are designed for all types of electric heated industrial furnaces. When we introduced the now world-famous KANTHAL iron-chromium-aluminium electric resistance alloys in the early thirties this represented a considerable rise in the maximum operating temperature of metallic resistance elements.
An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc.. Industrial arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking.
ture range from 550° to 580° C in a small electric resistance pot furnace and then dropped into a laboratory jaw crusher. The temperature of the metal samples was monitored during heating by a standard K-type thermocouple (Chromel-Alumel).6 The initial tests showed that the method did have merit.
2019329If the aluminum is pure, then melting it is not toxic, although the high level of heat required to melt it can be dangerous, so all care must be taken when melting it. Scrap aluminum is another matter; unless you know exactly what else forms part of the scrap containing aluminum, there is a risk of toxic substances being present (e.g. plastics
Cast iron is sometimes melted in a special type of blast furnace known as a cupola, but in modern applications, it is more often melted in electric induction furnaces or electric arc furnaces.  After melting is complete, the molten cast iron is poured into a holding furnace or ladle.
was melted respectively in the electric resistance furnace and the temperature of the melt was main-tained as 720C for use. The sprayer device compris-es a nitrogen gas tank A, a relief valve B, a mano-meter C, an air filter D, a molecular sieve. E, a gas flow-meter F, a porous plug P and some solenoid valves V, as shown in figure 1. 1.
125kw Inductotherm VIP-I Precious Metals Melting System: The furnace was only used for proof of concept in a platinum recovery project and has extremely low hours. It is practically new It is a top of the line, USA built, VIP- I Inductotherm system using their latest IBGT technology and was specifically designed to handle non-ferrous metals
A typical electric resistance melting furnace will have an energy density concentration of 64,557 BTU/ft 3 as opposed to the new PAM with 269,146 BTU/ft 3, for equal volume of hot zones. The PAMF has 4 times higher energy per unit volume compared to electric resistance furnace, thus making it a unique furnace with highly concentrated power.
The extreme ends of the elements are coated with aluminum contact surface with low resistance to which the electrical connections are made with braided aluminum straps. Elements are described by giving the- overall length, the heating section length, the diameter and the resistance. Silcarb manufactures the following types of SiC heaters

Alibaba.com offers 1,169 150kg melting furnace products. About 81% of these are industrial furnace, 1% are jewelry tools & equipment. A wide variety of 150kg melting furnace options are available to you, such as induction furnace, resistance furnace, and arc furnace.
It is recommended that element calculations be worked out before furnace construction is started, as the size, number and length of the element support grooves (or tubes) required will be affected by the element design. Also, if a three-phase supply is to be used, it is helpful to have the number of elements divisible by three.
