What are the chemical and physical indexes of magnesia carbon brick?
There are different grades of magnesia carbon brick. And it is usually used for the lining and tap hole of steelmaking converter, the sidewall and slag line of high power electric ARC furnace and ladle slag line.
Can electricity arc from an electrical line to an object that isn't touching it?
Yes, within certain conditions it can. That is essentially the practice of arc ray lamps and electric welding.
Why does air need to be at low pressure to create an electric arc?
Air is a relatively poor conductor of electricity, it is an insulator. Removing air creates an easier path for electrons to jump and create an arc.
How does a reflex arc help maintain homeostasis?
Homeostasis works as a negative feedback mechanism, which is a kind of reflex action. When the body detects changes in external/internal environment, the receptor will generate a nerve impulse to the coordination centre and then make a response through effector. This is a reflex arc.
What was the first lighthouse to have electricity?
A lighthouse in Dungeness, England, was equipped with a carbon arc lamp in 1862. That was the first electric illumination in a lighthouse, according to the Encyclopedia Britannica.
What is an EAF?
EAF stands for electric arc furnace.
What is EAF?
EAF stands for electric arc furnace.
How to use copper pad in electric arc furnace machine?
Sensitive equipment like a furnace machine requires the services of a qualified electrician. Call one to have the copper pad in the electric arc furnace machine fixed.
What makes spark at water panels in electric arc furnace?
Not appropriate earthing condition
Why eccentric bottom tapping is named eccentric in electric arc furnace?
off center
How do you calculate diameter of electrode for an electric arc furnace?
i don't know please give me the answer
What is direct arc electric furnace?
An Electric Arc Furnace (EAF) is a furnace that heats charged material by means of an electric arc.Arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast ironproducts) up to about 400 ton units used for secondary steelmaking. Arc furnaces used in research laboratories and bydentists may have a capacity of only a few dozen grams. Industrial electric arc furnace temperatures can be up to 1,800 °C, (3272 °F) while laboratory units can exceed 3,000 °C. (5432 °F) Arc furnaces differ from induction furnaces in that the charge material is directly exposed to an electric arc, and the current in the furnace terminals passes through the charged material.
Why electric arc furnace shell to be grounded?
Which is the mínimum distance between the electrode an a grounding part.
Is the circle diagram possible for transformers?
Yes it is possible. They do it for Electric arc furnace. (one of the application I am aware of)
What is the diameter of submerged arc furnace?
Submerged Arc Furnace is also called smelting furnace. The furnace is called submerged Arc because Soderberg(Carbon) Electrodes are , buried inside the charge mix. Though Arcing is there but can not be seen. This Furnace is used for producing Ferro Alloys,Pig iron,Silicon metal, Calcium Carbide, Ferro Silicon,Ferro Chrome, Silico Manganese
What is the mass of steel when in an arc furnace?
400kg
Electric arc furnace how is it charged?
There are several ways of charging the Electric Arc Furnace(EAF). 1. 100% Scrap Charging by opening the furnace roof and introducing scrap bucket into the furnace shell. In this process 2-3 charges are taken for reaching the designed capability of furnace. This results heat loss when roof is opened. 2. In latest process DRI/Sponge Iron is fed from roof hopper, continuously, into the molten metal pool. 3. In another process, hot metal(from blast furnace) is introduced from slag door or roof top. This is the most effective method for reducing Tap To Tap Time(TTTT).
