How do you calculate forging tonnage?
To calculate forging tonnage, you can use the formula: Tonnage = (Area of the part in square inches) × (Material yield strength in pounds per square inch) × (Safety factor). The area can be derived from the dimensions of the part being forged, while the yield strength varies based on the material. Typically, a safety factor of 1.5 to 2 is applied to account for variations in material and process conditions. This calculation helps determine the necessary force required for the forging operation.
What are the chemical properties of a ss304L plate?
A SS304L plate is made of stainless steel, which typically contains iron, chromium, nickel, and small amounts of other elements. It is known for its high corrosion resistance due to the presence of chromium oxide on the surface. SS304L is non-magnetic in the annealed condition and has good formability.
Which gas is made in the furnace and reduces the iron ore to iron?
Methane gas can reduce iron oxide to iron metal. This process was first tried and tested in Mexico by the method of HYLSA Hojalata y Lamina Sociedad Anonima. Now the process is used in the plant Lazaro 'Cardenas Mexico to produce direct reduced iron ore to iron sponge.
What is the difference between metallurgy AND chemistry?
Metallurgy is the branch of science and technology concerned with the properties of metals and their production and purification, while chemistry is the branch of science that deals with the composition, structure, properties, and changes of matter. Metallurgy focuses specifically on metals and alloys, while chemistry encompasses a wider range of elements and compounds.
No, CRCA (cold rolled close annealed) sheet is made of steel and is a ferrous material. It undergoes a cold-rolling process to reduce thickness and improve surface finish, making it suitable for various applications in construction and manufacturing.
When metals become cold, they contract and take less space, but when a metal gets hot, it expands and it will need more space. So, in this case the metal tracks took less space when fitted without gaps on the cold day, but on the hot day the metals will need more space and therefore will push outwards. The tracks will become buckled, and when the train comes, it will go off track.
It is rare, It is pretty, it doesn't rust and most importantly silver is widely used in nano technology and super-computer production because silver is the best conductor of any known metal. There is also cultural phenomenon to desire silver for jewelry and coins. As population grows, desire for silver grows to keep up with population. LATELY SILVER PRICES HAVE BEEN GROWING RAPIDLY AND DEMAND HAS INCREASED DUE TO THE GLOBAL, INTERNATIONAL CAMPAIGN "CRASH JPMorgan - BUY SILVER!"
Which process is generally used in extracting magnesium in metallurgy?
Fused salt electrolysis is generally used in extracting magnesium in metallurgy. In the extraction of metal, magnesium is usually extracted by the electrolysis of fused anhydrous MgCl2 because of its reactive nature. Another process uses silicon to reduce magnesium oxide.
Wich of the following is not a casting effect?
Milling is not a casting effect. Casting effects typically refer to factors that affect the casting process of metal or other materials, such as shrinkage, porosity, or inclusions. Milling, on the other hand, is a machining process that involves removing material from a workpiece using a rotating cutter.
How do you avoid slag inclusion?
To avoid slag inclusion in welding, make sure to properly clean the joint and remove any contaminants like rust, oil, or paint. Use the correct welding technique and parameters to ensure good fusion between the base metals. Additionally, selecting the appropriate welding consumables and maintaining a consistent travel speed can help prevent slag inclusion.
If the brass ball on top of the flagpole falls will it break?
The brass ball on top of a flagpole is designed to be durable and withstand normal weather conditions. However, if it falls from a significant height, it may break upon impact with the ground or another hard surface.
What are the various phases exist on Fe-Fe3C diagram?
The various phases that exist on the Fe-Fe3C diagram are austenite, ferrite, cementite (Fe3C), and a mixture of ferrite and cementite known as pearlite. These phases form at different temperatures and carbon concentrations, and their distribution determines the properties of the steel.
Why is the head of a hammer made of iron and not lead?
Iron is used for hammerheads because it is much stronger and more durable than lead. Lead is too soft and would deform easily, making it unsuitable for withstanding the impact forces generated when striking objects with a hammer. Iron offers better impact resistance and ensures that the hammerhead retains its shape and effectiveness over time.
Why is the head of a hammer made from iron why not lead?
The head of a hammer is typically made from iron because iron is stronger and harder than lead. Lead is a softer and less durable metal, so it would not be able to withstand the repetitive impact and pressure that a hammer head is subjected to during use. Using iron ensures that the hammer head is able to effectively drive nails and perform other tasks without becoming distorted or damaged.
What is use of hydrogen in metallurgy?
Hydrogen is used in metallurgy for processes such as hydrogen reduction and hydrogen embrittlement. In hydrogen reduction, hydrogen gas is used to reduce metal ores into pure metals. However, hydrogen embrittlement can occur when hydrogen atoms penetrate the metal structure, causing it to become brittle and susceptible to cracking.
Metallurgy was developed to extract and refine useful metals from ores to make tools, weapons, and other important items. It allowed societies to manipulate and shape metal to suit their needs, leading to advancements in technology and civilization.
Why did the metallurgy industry start?
The metallurgy industry started to meet the demand for metal products such as tools, weapons, and infrastructure. It developed as humans learned to extract and process metals from ores, leading to innovations in technology and society.
Why can't iron and sulphur be separated?
Iron and sulfur cannot be easily separated because they form a compound called iron(II) sulfide when mixed together, which is a chemical bond. To separate them, a chemical reaction is needed to break the bond and convert the compound back into its individual elements. Simply physically separating them, like with a magnet, won't work due to the strong chemical bond formed.
What are the fields of metallurgy?
Some fields of metallurgy include extractive metallurgy (extracting metals from ores), physical metallurgy (studying the physical and mechanical properties of metals), and metallurgical engineering (applying metallurgical principles to the design and production of metal components).
What are the three major steps involved in metallurgy?
The three major steps involved in metallurgy are mining, beneficiation or ore dressing, and extraction of metal. Mining involves the removal of ore from the Earth's crust, beneficiation involves processing the raw material to improve its quality, and extraction of metal involves obtaining the pure metal from its ore through various methods like smelting or leaching.
What is the electrode potential of aluminium?
The standard electrode potential of aluminum is -1.66 V. This means that in a standard electrochemical cell, aluminum tends to be oxidized (lose electrons) rather than reduced.
Is metallurgy good course to study in nit?
Yes, metallurgy is a good course to study in NIT (National Institute of Technology) for those interested in materials science and engineering. NITs typically offer high-quality education in this field, with opportunities for research, internships, and career advancement in industries such as manufacturing, aerospace, and automotive.
How are metallurgy and alloys connected?
Metallurgy is the study of metals and their properties, while alloys are mixtures of two or more metals. Metallurgists use their knowledge of metallurgy to create and manipulate alloys, taking advantage of unique properties that result from combining different metals. Alloys are commonly used in various industries due to their improved mechanical, electrical, or chemical properties compared to pure metals.
