Determine the heat input per unit of time by multiplying the steam flow by the heat input (11340kg/hr x 1,203.3 btu/lb), which is 30,083,500 btu/hr. Convert the heat input from the steam flow into a unit of power in megawatts. This is done by using the conversion 1 btu/hr is equal to 2.93e-7 megawatts.

Perimeter = 20×4 = 80mm. Thickness = 3mm. Shear Strength = 0.3447kn/mm 2. Punch Force (KN) = 80 x 3 x 0.3447 = 82.728 KN Convert into tonnage: 82.728 KN ÷ 9.81 = 8.43 Ton. For more details about the shearing strength including how to calculate it, you can refer to the answer from Wikipedia.

To produce a ton of steel in an electric arc furnace requires approximately 400 kilowatt-hours (1.44 gigajoules) per short ton or about 440 kWh (1.6 GJ) per tonne; the theoretical minimum amount of energy required to melt a tonne of scrap steel is 300 kWh (1.09 GJ) (melting point 1,520 °C (2,768 °F)). Therefore, a 300-tonne, 300 MVA EAF will ...

A screw conveyor is required to transport 10 tons per hour of unslaked lime with a bulk density of 60 lbs/ft 3. The unslaked lime also needs to be mixed in transit using cut and folded flights. The conveying distance is 15-feet, so short (2/3) pitch screws will be used to ensure proper mixing.

used on stainless steels can be sum-marised as follows: • a concentrated heat source, leading to a narrow fusion zone; • a very stable arc and calm welding pool of small size. Spatter is absent and because no flux is required in the process, oxidation residues are elimin-ated so that any final cleaning opera-tion is very much simplified;

Nov 12, 2013· Power consumption at standard kW/kg ratio for Cast Iron (Ingot) is 560 kWh/ton. Means one ton of Cast Iron (Ingots) requires 560 kW for one hour (kWh). This number is varying for the metal to metal. This number is also depends on the type of the physical charge. This number is different if the physical charge is scrap.

Feb 24, 2006· I was an estimator for a northern-midwest steel fabricator 5 years ago. At that time, fabricated and delivered, pre-bid price per ton was $1200 to $1500 per ton for structural. $1500 to $2500 for miscellaneous steel. Call a local contractor or erector for erection costs. Notice that I gave you the "pre-bid" price for steel.

The electric power used in EAF operation, however, is high, at 360 to 600 kilowatt-hours per ton of steel, and the installed power system is substantial. A 100-ton EAF often has a 70-megavolt-ampere transformer. The process. After tapping a heat, the roof is moved away, and the hearth is inspected and, when necessary, repaired.
