live chatWhen you choose torque, this calculator will measure the approximate torque of an engine based on the horsepower, multiplied by 5,252 (conversion between foot-pounds and horsepower), divided by the RPM of the engine. For example, if your engine has 350 horsepower then the torque would be 367 foot-pounds, at 5,000 RPM.G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 11.5.1 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic - ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap. For the roughing mill (reversible 4-high) both roll force ...Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening.The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

The Brit-ish Iron and SteelResearch Association (B1SRA) AGC method based on the gaug meter principle and the feede forward AGC method using the delivery time of the strip have been widely utilized in steel rolling mills [3]. Strip products thickness precision is an important quality parameter. · MRR = .200 x 1.64 x 19.5 = 6.4 in3/min. For horsepower at the motor (HPm), use formula: HPm = HPC/E. In determining horsepower consumption, "K" factors must be used. The "K" factor is a power constant that represents the number of cubic inches of metal per minute that can be removed by one horsepower.The Hot Rod Calc Road and Strip Performance Calculator is manufactured by Calculated Industries, and distributed by Mr. Gasket a division of Prestolite Performance.

By Robert A. Sladky Vice President Tube Mill Engineering Many "W" style mills that have the ability to shim up the bottom driven shafts in each section to maintain metal line after tooling is reworked, and are many times also equipped with a individual motor drive in each of the three sections as illustrated below. · It is well known that there are sharp peaks (friction hills) in the specific roll pressure curves predicted by Sims formula and Цeликoв formula which result in large errors for hot rolling. 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.

Learn more about how horsepower affects performance, or explore hundreds of other calculators addressing topics such as math, finance, health, fitness, and more.An example of rolled material would be a rolled carpet or a rolled sheet of paper from the paper mill. The length units that can be used are yard, feet, inch, meter, centimeter, millimeter, mil, and micron. A mil is equal to one thouh of an inch. A micron is equal to one thouh of a millimeter. The initial units used in the table can ...•Roll-strip contact length L •Average strip width w -despite the fact that spreading, or an increase in width, may actually occur if edger mills are not used •Average true stress of the strip in the roll gap Y avg •Assumes no friction and thus predicts lower roll force than the actual value •Power per roll (SI units)= pFLN / 60,000 kW.
