The following are to links of sheet metal design resources, tools, articles and other useful data.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done. There are many different standards and types of horsepower. Two common definitions being used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts.
This free engine horsepower calculator estimates vehicle engine horsepower using two different methods, the elapsed time method and the trap-speed method. Learn more about how horsepower affects performance, or explore hundreds of other calculators addressing topics such as math, finance, health, fitness, and more.
Calculation of hydroelectric power and energy Principle. The principle of hydro electricity generation is quite simple. Circuit waterworks provides the necessary pressure of water supplied to the turbine blades, which drives a generator, producing electricity. Formula to calculate hydropower. How to calculate output power of a hydroelectric ...
Dec 17, 2012· Though horsepower units are a derivative of the 33,000 ft-lbf/min, it is not critical to understanding how to calculate motor horsepower for speed and torque. Another common unit of power that motors are rated in is watts. The conversion from watts to horsepower is 745.7 watts = 1 hp.
Here are the formulas for calculating motorcycle and automotive performance. Many of the formulas use the value of pi which is 3.1415927 Some formulas contain notation such as ^2 which means "squared" or ^3 which means "cubed"
The ratio λ = [ a/Lp] = [a/√R.∆t] is used to calculate the moment arm 'a' λ =0.5 for hot rolling and 0.45 for cold rolling. The torque is equal to the product of total rolling load and the effective moment arm. Since there are two work rolls Torque Mt = 2P.a Consider two high roll mill as shown in the figure.
In other words, for very fast cars in the 1/4 mile the LRT formulas predict more hp than is actually needed for the highest level of performance, and the Hale formulas predict less hp than is needed based on ET but are close when mph are used. At 550 bhp and above, the Fox formulas do a good job of predicting both ET and mph.
Thus roll bending is a controllable parameter to modify the roll gap and hence the crown and flatness of the strip rolled in the finishing mill of the hot strip mill. Conclusions. Roll stack deflection is an important issue in the determination of profile and flatness of a strip rolled in hot strip mill.
Horsepower to Torque Converter is an online tool used in electrical engineering to calculate how much torque will be generated according to the input power value either in horsepower or watts. Generally, horsepower is a unit for measuring the power of various electrical motors, piston engines, steam turbines etc and it is equal to 746 watts or ...
MOTOR FORMULAS AND CALCULATIONS: The formulas and calculations which appear below should be used for estimating purposes only. It is the responsibility of the customer to specify the required motor Hp, Torque and accelerating time for his application.
Drag Performance Calculator By AssassinRacing.com Calculate the theoretical 1/8 Mile ET, 1/4 Mile ET, 1/4 Mile Top End Speed, and Ideal 1/4 Mile Gear Ratio for a given application based on the Vehicle Weight (in pounds), Vehicle Horsepower (at the flywheel), RPM through lights (finish line), and Tire Diameter (Height) in Inches.
6 Common Boiler Formulas FORCE What is the force of 260 lbs of pressure exerted on 8 sq. in.? F = P/A F=PA F=260/8 F=32.5 Where, F force (psi) P pressure A area HORSEPOWER (PUMP) What is the horsepower of a pump that moves 450 lbs of water against a discharge head of 220 ft. In 1 minutes? Disregard friction and other losses.
Horsepower Calculator. Horsepower is a measurement of power, or the rate at which work is done. This calculator can be used to compute horsepower according to its definition and to convert between different power units. To find the engine horsepower of a vehicle please use our Engine Horsepower Calculator.

Rolling processes 5-1 introduction: Rolling is the process of reducing the thickness or changing the cross section of a long workpiece by compressive forces applied through a set of rolls, as shown in figure (5-1). Fig. (5-1) Most rolling is carried out by hot working, called hot rolling, owing to the large amount of deformation required.
In this paper, a new specific roll pressure formula is derived from the Navier-Stokes equation (N-S equation) by the hydrodynamics method (HM) with assumptions that strip materials take the characteristics of viscous fluid during plastic deformation of hot rolling processes.
Dec 20, 2005· Use the formula (m*9.81*h)/t=HP to calculate your watts. In this instance, m = your weight, h = the height of staircase, 9.81 is the gravitational constant that must be taken into account, and t = time (in seconds) of your climb. The resulting number you get is expressed in watts.

to which ArcelorMittal South Africa produces hot strip mill products. Tolerances are based on EN 10051 or ASTM A568M/635M. When hot rolled strip is produced in accordance with JIS or any other international specification, tolerances in accordance with that particular specification will apply.
For example, a 1,600 cc motor in a good state of tune requires about 54 cubic feet per minute to make 78 horsepower. This calculator uses the formula: Air flow (CFM) = (Horsepower × 0.625) × 1.1104 Estimating horsepower by air flow If you have access to a flow bench, you can measure how much air flow you get through your intake and cylinder head.
