II.INDUSTRY PROFILE 2.1.INDUSTRY PROFILE(Fondry Industry): Foundry industry is a branch of industry that produces the castings by filling molds with molten alloys. The volume of foundry production in the world is more than 80 millions. Casting is used to produce an average of 40%(by weight) of stock for machine parts,bt in some areas of machine building, such as appliance tool manufacture, the percentage of castings is 80 percent. Appliance building consumes about 70 percent of all cast stock, the
of centrifugal force, these parts have very fine grain on the outer surface and it consists mechanical properties nearly 30% greater than parts formed with static casting methods. Maybe this parts formed from ferrous metals like low alloy steel, stainless steel, and iron. And also non ferrous metals like aluminum, bronze, copper, magnesium and nickel. The process of centrifugal casting is done by most of the industries like aerospace, industrial marine and power transmission. Parts which are produced
Anemia is defined as a condition in which the blood is deficient in red blood cells, hemoglobin, or both or deficient in total volume. Iron deficiency anemia is the lack of iron to form normal red blood cells. Iron is imperative for almost all organisms because of its ability to donate and accept electrons with relative ease (Pantopoulos et al., 2012). Iron is required for cellular metabolic functions, oxygen carrying proteins, and cell growth and development. Those affected the most by iron deficiency
Manmade and Natural Materials Students like myself need to know what materials are available, how they behave in use and how they can be worked or processed during manufacture and construction. Having a good understanding of these will help me to select suitable materials for my products. In choosing materials for a particular project, I will need to consider their physical and working properties, so that I am able to decide which material is best and which method of processing is
water. Gold panning can be a slow process when compared to other prospecting methods. GOLD DETECTING Gold detecting is the process of finding gold with the aid of a metal detector. A metal detector is an electronic device designed for locating ferrous materials on or below the surface of the ground. Metal detectors have been in existence for many years. In fact, some of the first metal detectors were developed during World War II to detect dangerous, explosive land mines. In later years, metal
cost (20-40% less than steel) (Xu et al., 2005). It is used in such diverse applications as cookware and musical instruments to auto parts and heavy machineries. Microstructure of grey cast iron is characterized by dispersion of graphite flakes in a ferrous matrix. It has been evidently shown that the size, morphology and distribution of graphite flakes greatly affect the physical and mechanical properties of grey cast irons and that these characteristics depend mainly on the chemical composition of
Normal Iron Metabolism: If the body is absorbs an enough of the right nutrients a well balanced diet will be achieved. Roughly 2mg of iron is lost daily due to desquamation of epithelia. Iron is mainly lost at a more drastic rate during menstruation cycles, haemorrhages. During pregnancy there is a more drastic demand for iron which also increases iron absorption to 20%. The two main absorption sites of iron is the duodenum and the upper duodenum. The divalent metal transporter takes the absorbed
communication, November 18, 2014). Clayton County Recycling receives its material from all over the region. The site has contracts with many different businesses to process waste metal. The CCR also purchases scrap from individuals. The current rate for ferrous metal is $150 a ton, the price being determined by supply and demand. Home and auto sales, which require large amounts of metal in their construction, directly affect the going rate for salvage. Large disasters, such as hurricanes, earthquakes,
In this experiment, a series of biochemical test and API 20 E test are carried out to identify the unknown bacterial species provided. MacConkey agar, a selective and differential medium which is designed to isolate and differentiate the gram negative enteric bacteria. Bile salts and crystal violet inhibit the growth of gram positive organisms. Lactose provides a source of fermentable carbohydrate, allowing for differentiation of lactose fermenting bacteria from lactose non-fermenting gram negative
Have you ever wondered why one of your breads are molded and the other one still looks fresh in my experiment I will answer that question in my experiment. My project is “What Type of Bread Will mold the fastest between wheat and white. So I think that the wheat bread will start to mold faster that white because it has a lot more nurturance then white bread and nurturance is what mold needs to grow. Mold is a minute fungus that lives on food and other places. About 10,000 to 300,000 but know
In this essay I will be discussing the issue of push and pull factors of Sydney`s climate and environment. Sydney has long been hospitable city for people from Australia and around the world. Some people come here to visit, and some stay forever. Furthermore, people move here to find work and accommodation. Location of Sydney Sydney is the largest city in Australia area of 12,144.6 km ² which has a population 4.5 million people (2009). City is located on the southeastern coast of Australia, near
The treatment of surface wastewater is aimed at bringing contaminated water back to its previous state for domestic use or otherwise. Some of the sources of wastewater include industrial effluents from manufactures, agricultural effluents, agro-industrial as well as domestic wastewater from sinks, bathtubs, toilets, and so on. Particles in the water from the various sources include bacteria, organic matters, and sand which cause the water to be turbid or discoloured in appearance and have an unpleasant
Introduction Metallurgy is the field of materials science and material engineering that studies the physical and chemical behaviour of metallic elements, their microstructure compounds and their mixtures, which are mostly known as alloy. Metallurgy can be refers as the technology of metals where science is applied to the production of metals, and the engineering of metal components for the uses of products for consumers and manufacturers. Metals are widely use in industrial, economic growth and
chain for e-waste recycling through Attero consists of four stages: • First Stage - Manual segregation of components, where different parts of E-waste are separated. • Second Stage - The mechanical separation process is applied. In this process, ferrous, aluminum, plastic and nonferrous material are initially separated. • Third Stage - The plastics are then recycled by Attero Group’s innovative plastics recycling process which further processes the plastic. • ... ... middle of paper ... ...reproduced
In the report by Sullivan et.al (7), they tabulated the material composition of a generic mid-size car, and the ferrous materials which used (cast iron and steel) make up nearly two thirds of the total vehicle weight. However, this fraction has been reduced significantly over the last several decades as lighter materials like aluminum and plastics have begun to supplant the use of ferrous materials. According to the EEA, simply making more efficient engines might not be enough to reduce pollution
Transportation is one of the basic necessities of human civilization. If there is no transportation on land, sea, or air, there may not be communication between human beings on this planet. But there are also side effects of transportation, which includes pollution. Pollution means the harmful wastes produced by humans which damage our environment in many ways. The fast population growth rate of humans means that the necessity for transportation vehicles is also enormously increasing. Studies have
the cathode. If the alkalinity present in the water becomes excessive, it can corrode the cathode as well. From the anode and the cathode The Fe2+ ions (at the anode) and OH- ions (at the cathode) diffuse and form ferrous hydroxide. Fe(aq)2++2OH-⟶Fe(OH)2↓ If enough oxygen is present, ferrous hydroxide gets easily oxidized to ferric hydroxide 4Fe(OH)2+O2+2H2O⟶4Fe(OH)3 This product is called Yellow Rust, which corresponds to Fe2O3.H2O. If the supply of oxygen is limited, the corrosion product may be black
Hazardous waste management is defined as the collection, treatment and disposal of unwanted material that poses the threat to the environmental chemical under managed conditions. In the hazardous management system, the treatment technologies are an inevitable method for a waste management stream. Treatment process is a significant method used to minimise the amount of hazardous waste produced and recover useful products. It can be classified into chemical, physical and biological methods.
