INTRODUCTION TO STEEL- CLASS 1 = 14-08-2020

 • steel is just another type of iron alloy, but it has a much lower carbon content than cast and wrought iron and other metals are often added to give it extra properties

• IT is to make strong substance made of iron and carbon, to make something strong or tough
• steelmaking involves 
• casting – steel is melted and poured into mould
• forging -  shaping of steel using compressive forces
• rolling – steel is passed in to rollers to have a uniform thickness
• drawing -  drawn product with accurate tolerances, favorable grain structure, improved material properties and good surface finish.
• extruding - forced to flow through a die of a smaller cross sectional area, thus forming the work to the new cross section
• Main uses of steel
• It is used in construction of road, railways, infrastructure and buildings

BLOG 16- FABRICATION, ERECTION AND HYBRID STRUCTURES

 FABRICATION, ERECTION AND HYBRID STRUCTURES FABRICATION: Fabrication is the process used to manufacture steelwork components that will, when assembled and joined, form a complete frame.   The process of steel fabrication involves grinding, welding, cutting, bending, drilling, punching, burning or melting, and other general crafting methods using various  high-quality tools and CNC equipment . The entire steel fabrication process is systematic and requires the utmost planning, precision, and knowledge. Steel fabricators are well aware of all the crucial steps and measures that need to be taken care of in the fabrication process.  Structural steel is usually fabricated to create structures like beams, trusses, hollow sections, angles, and plates. ERECTION : The erection of structural steelwork consists of the assembly of  steel components  into a frame on site. The processes involve lifting and placing components into position, then connecting them together...

Terminologies and Classification - Blog 7 - Yukta Yogeesh

 26/August/2020 Today's session was more properties of Steel and similar metals for learning more details and workability with different ways and methods: -    Galvanic Action  Higher end is anode and at the lower end is th cathode. When current is passed through a combination of metals, the one at the higher end will corrode first.  Co-efficient of thermal expansion  Charge/length of materials/degree of change in temperature Specific Gravity Density of substance/ Density of water  Tensile/Yield strength  Tensile strength is the maximum ability of the metal to withold stress, will show necking and will fail at a point called fracture.  Tield strngth is the maximum ability of the metal to exhibit elasticity after which it cannot undergo deformation and will become plastic. Reflectivity  p(y)=Gr(y)/Gi(y)  Where P is the reflectivity, Y is the wavelegth, Gr is reflecting radiation, Gi is the incident radiation Oil Canning  An elas...

  Steel fabrication, erection and hybrid construction Fabrication: In fabrication methods such as grinding, welding, cutting, bending, drilling, punching, burning or melting are involved. High quality tools and Computer Numerical Controller equipment is also used. Crucial steps and measures are needed to be done in this process. Structural steel is usually fabricated to create structures like beams, trusses, hollow sections, angles and plates. Structures have to be specifically designed and fabricated before constructing and assembling them together.   Steel erection:   Erection is done with the help of cranes or by jacking and lifting and placing components. Bolted connections are done to keep the components secure and bracing is also done. Structure alignment is essential by checking the column bases to be lined and levelled. The process involves lifting and placing an exact position by connecting together. Connections may be achieved by bolting,...
