Modern steelmaking processes can be divided into two categories: primary and secondary. Primary steelmaking involves converting liquid iron from a blast furnace and steel scrap into steel via basic oxygen steelmaking, or melting scrap steel or direct reduced iron (DRI) in an electric arc furnace.
– Weight of bar in kg/meter should be calculated as (d2 ÷ 162) where’d’ is the diameter of bar in mm.
– ‘L’ for column main steel in footing should be considered as minimum 30cm/as specified.
– For bent up bar add 0.42d in straight length of bar where’d’ is the clear depth of beam/slab.
Beside this, Can you make steel at home?
In order to create custom pieces, you need to either melt the metal and cast it in a mold, or heat it until it’s soft enough to shape with your hammer. Properly melting metals can be a bit dangerous in our home shop, but we can make a coffee can forge for all of our home blacksmithing needs.
Likewise, How do you calculate steel in a beam?
– Length = 4 m.
– Height = 500 mm. Width = 300 mm.
– Solution: Main bars (20 mm):
– length = length of beam + development length – bend. #Where.

– Length: …
– = 4000 + (50×20×2) – (2×20×2) …
– =5920 mm or 5.92 m Ans..

What is 162 in steel weight calculation?
D² /162 gives the weight of the round bar per metre, where D is taken in mm. It comes from the basics of weight calculation. i.e. volume × Density. Density of Steel Bar is 7800 kg./m³.
How do you calculate 162 steel?
Calculation Of The Formula D²L/162: The weight of steel bars= Cross sectional area of steel bar x Length of steel bar x Density of steel bar.
How do you calculate volume of steel?
First calculate the volume of the steel sheet. = 0.15 m^3. Note: If you are calculating the weight of circular steel reinforcement bar than calculate its volume by using this formula (πD^2/4) and then just multiply by the density of steel which is 7850 kg/m^3.
How do you calculate reinforcement of a beam?
– Length of B1 = clear distance between walls + 2 x width of walls – 2 x bar cover + 2 x bend length.
– Length of bar B2: A + B + C = 4000 + 2 x 230 – 2 x 40 + (1.414xH – H)
– B2 = 4000 + 2 x 230 – 2 x 40 + (1.414×334 – 334) = 4518.3 = 4520mm.
How do you calculate the weight of steel?
Width * Length * Thickness * Density = Weight.
Do you need coal to make steel?
Steel is an essential material for modern life and global steel production is dependent on coal – 70% of steel produced uses coal. Metallurgical coal – or coking coal – is a vital ingredient in the steel making process. Coking coal is converted to coke by driving off impurities to leave almost pure carbon.
How do you calculate steel?
– Weight of bar in kg/meter should be calculated as (d2 ÷ 162) where’d’ is the diameter of bar in mm.
– ‘L’ for column main steel in footing should be considered as minimum 30cm/as specified.
– For bent up bar add 0.42d in straight length of bar where’d’ is the clear depth of beam/slab.
Is steel naturally made?
Steel is what is known as an alloy, meaning it is not naturally found but instead is man-made, composed from a combination of different materials and metals.
How do you convert steel to weight?
If you have 10 cm3 of steel with a density of 7.85 g/cm3, the mass would be 78.5 g or 0.0785 kg. You can convert mass to weight by multiplying it by 9.8 m/s2 to get 0.77 newtons of steel.
How do you make steel from raw materials?
Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route.
What is the formula to calculate steel?
STEEL QUANTITY: Weight of bar in kg/meter should be calculated as (d2 ÷ 162) where’d’ is the diameter of bar in mm. ‘L’ for column main steel in footing should be considered as minimum 30cm/as specified. For bent up bar add 0.42d in straight length of bar where’d’ is the clear depth of beam/slab.
How do I calculate how much steel I need?
– (Calculation of Bars No’s) First, calculate the number of bars required (main and distribution both). FORMULA = (Total length – Clear cover)/center to center spacing + 1. Main bar = (5000 – (25+25))/100 + 1. = 4950 Divided by 100 + 1. = 51 Bars. …
– (Cutting length)
