Casting buyers keep moving forward for long-term business ties with a few foundries that are reliable rather than short-term cost-based purchase agreements with several foundries. In order to maintain a long-term partnership, an ideal professional metal caster must be able to establish his business through diversification of his customer base and market space.
Stainless steel is an alloy of steel with chromium as one of its elements. The other alloying elements may vary according to the structural and chemical properties required for the stainless steel. It is used in a wide range of applications from automobile to shipping components and consumer products to bulk material and handling equipment. One of the major positives of stainless steel is that it never easily corrodes because of the presence of chromium.
Nodular cast iron can be identified on the basis of its structure that differentiates it from the other types of cast iron. Ductile iron or nodular cast iron can be identified into different grades depending upon the microstructure, chemical composition, mechanical properties and physical properties. This type of ductile iron is mainly used for the manufacture of pipes used for water supply lines. Ductile iron is also used in manufacturing various automotive components. Other uses include agricultural vehicles, trucks, tractors, oil pumps and sewage lines. They are also used in the production of durable propeller shafts.
Cast iron is one of the most extensively used alloys of ferrous. It is made from pig iron by the process of casting and hence the name. Pig iron is placed in the furnace along with other alloying elements and melted until the molten mixture is obtained. The molten mixture is then poured in casts or molds of required dimension and left to solidify. The resultant solid obtained is the cast iron which finds its use in a myriad of industries.
The discovery of iron dates back to as early as 1200 BC. The first form of iron known to ancient man was wrought iron. The Iron Age in India is denoted as the Indus valley Civilization. Telluric iron is the native form of iron. This was in metallic form on the earth surface and was similar in texture to the iron from meteors. It contained about 6-8% Nickel.
Industrial wastewater has an adverse impact on the environment. This has become a huge concern for all over the world as the wastewater released is toxic in more than one ways and affects all lifeforms dramatically. This is why safe disposal of industrial wastewater hold a huge significance for the environment. Strict adherence to industrial and government standards should be met all times to prevent and reduce water and soil pollution. This has led to invention of treatment of the industrial wastewater that will protect the ecosystem.
Steel undergoes the process of rolling to reduce the thickness of the metal as well as make it uniform. In this process, steel is placed between two rolls where the thickness is altered by manipulating the length direction of the steel rather than the width direction. This is because the point of contact between rolls […] Read More
Hot Strip Mill :
Process :
The primary purpose of a hot strip mill is to reheat thick steel slabs into thin sheets with varying thickness. The thick steel slab passes through several rolling mill stands that are driven by powerful motors. The rolled sheets then pass through coilers, thereafter these coils move on to the next process in the plant. From the startup to the end, the steel material undergoes several treatments through each stage that are the main features of a hot strip mill. Though traditional strip mills had limited facilities, modernization has brought many changes in order to meet out the market demands.
Continuous casting, also known as strand casting, is the process where a metal is heated until it liquefies. The molten metal is then allowed to solidify until it becomes a semi-finished slab that is later rolled in the finishing mill. It is used to cast metals of uninterrupted lengths. In this process, the molten metal is continuously supplied to the mold. The mold has an indeterminate length. When the molten metal is cast through a mold, it keeps travelling downward increasing in its length as the time passes by. The molten metal is continuously passed through the mold, at the same rate to match the solidifying casting. This results in casting of long strands of metal. The whole process of continuous casting is a precisely deliberated process that can produce astounding results.
Exposure to environment can affect components or parts made of steel. Changes in temperature or exposure to moisture and air can cause corrosion of steel. It causes a chemical reaction, which results in the oxidation of iron present in the steel. As iron occupies a majority of the volume of steel, corrosion leads to increase in volume but decrease in the strength of the steel product. It is, therefore, important to prevent this chemical reaction to maintain the quality of the steel.
Cold rolling of steel:
Cold rolling of steel is a process of treating steel below its recrystallization temperature. This method is used to get uniform thickness, increase thickness tolerances, and improve strength and a smooth surface finish through strain hardening. Though cold rolling has these advantages, the ductility of the cold rolled steel is reduced due to the dislocations that are formed due to cold rolling. In order to achieve good ductility, it is necessary that cold rolled steel must undergo a process called annealing. This reduces the stress in the steel that was formed during the cold rolling process.
Cast iron is preferred for various purposes including manufacturing of a range of pumps. It is best suitable for centrifugal pumps and sump pumps. Cast iron acquires some physical and mechanical properties that make it suitable for pump manufacturing. For high temperature applications, a suitable metal is chosen for the manufacturing of pumps based on three factors.
