Energy Reduction Technologies Based on the Lubricant Supply in the Roll Contact System "Quarto" during the Hot Strip Rolling M.V.
As a result, RLFS are used in a restricted mode, and power consumption reduction is not significant: 3- 6%.
Introduction The problem of the energy efficiency increase of the hot rolling process by applying a lubricant to the roll cage quarto contact system has been solved on the basis of the data obtained as a result of experimental studies on the broadband hot rolling mill 2000 JSC "MMK".

This grading would be qualified by production measures established by the shop floor data collection.
The data is ranked by the delivery date, which is the last time the product was roll formed.
This maintains the reliability and integrity of the Profile Database data.
The section profile types define the dimensional data that is stored and which can be searched on.
All data from the feedback report is logged and the Tooling Designer is provided with a copy.

The data requirements are nearly the same as for MRP.
Once these values are known, they become data for subsequent processing.
Validation of data were performed to ensure that these are for the right issue and useful.
Data validation checks that the data is sensible before it is processed.

Young’s modulus was determined from a least-squares fit to the data at stresses of at least 2 MPa, but below the proportional limit [10].
From fitting the experimental test data in Figure 3, values of n = 1.73 and m = 1.67 were obtained.
(Right) Linear fit to the same data based on the Gibson-Ashby relations in Equations 1 and 2.
The data presented in Figure 5 shows this trend is observed for all porosities investigated here.

Introduce No matter what exhaust after-treatment technology is adopted, a further reduction in the raw emissions of the engine is required.
Structure Optimization of Intake Ports The best procedure is to import CAD-data via the STL-interface and ensure that the CAD-data is showing the same engine as the hardware used at the experimental test rig.

The phenomena of the flow separation on high lift wings is avoidable phenomena where it causes reduction in lift, increase in drag, reduction in plane stability, as well as noise and vibration [1, 2].
In the present study, 2-D wing with NACA4412 airfoil section and an External load (E.L.) which simulates missile model were adopted to obtain qualitative data of the flow structure around the wing and the combination of the wing with attached missile.
The inclination to 5o AOA caused a reduction in the size of the separation region on the lower surface and possibly a virtual elimination of this separation.

A.Tasdemirci, et al, reported that Teflon and aluminum foam interlayer caused a significant delay and reduction in the magnitude of the stress wave transmitted to the composite backing plate and localized damage in the ceramic layer.
Further details of the experimental setup and the standard data reduction routines are available elsewhere.
It cannot be used to generate mechanical property data in the conventional way since essentially all of the necessary assumptions are violated.
We could confirm that the presence of interlayer could alter the stress wave transmission between the layers and cause a reduction in the magnitude of the stress transmitted to the Ti6Al4V backing plate.

The Pseudo-Voigt equation [4] is used to fit the data and to generate result files.
This size reduction accompanies the water loss inducing a lattice change.
To improve the reproducibility and the reliability of the data treatment, a PseudoVoigt fit has been chosen.
For our samples a temperature reduction of about 170°C is observed as the size decreases by three orders of magnitude.
So, this study highlights the applicability of the nanophysical properties to the nickel-bearing compounds and the reduction of the phase transformation temperature.

(a) (b) Fig.2 The curve of the rolling forces vs. increment (a) MethodⅠ; (b) MethodⅡ Transverse Wall Thickness Precision In order to increase the reliability of data of distribution of transverse wall thickness, simulated workpiece should pass through the last stand a longer distance.
Then five slices at exit of the last stand are analyzed, data processing method was introduced in detail in Ref. [8].
Maximal rolling forces, rolling moments all stands except the first stand have some degree reduction using methodⅡcompared with methodⅠ, and maximal rolling force and rolling moment reduce 10%~20% and 10% or so respectively.
Front tension, especially back tension can cause rolling force certain degree reduction.
Diameter increment reduction of rolled hollow tube is not obvious on the condition that front and back tension are small.

The results of the assessment of contamination of steel NMI Applied modifier Contamination with NMI according to state standard 1778-70 The average score of metal contamination by CANMI. pcs/mm2 Point oxides Fragile silicates Non-deformable silicates Maximum score Average score Maximum score Average score Maximum score Average score CANMI 1 CANMI 2 SC40 1.0 0.75 4.5 1.3 4.5 2.30 1.78 1.88 INSTEEL® 1.5 0.50 0.50 2.0 0.40 3.5 1.50 1.51 0.62 INSTEEL® 9.4 1.0 0.53 3.0 0.77 4.0 1.33 1.15 0.70 INSTEEL® 5.1 0.5 0.50 2.0 0.40 3.0 1.25 1.03 0.92 INSTEEL® 10.1 0.5 0.50 1.5 0.30 2.5 1.35 1.46 1.54 From the data of table 3 it follows that the maximum score of NMI and the average level of contamination for the main types of NMI reduction is provided when processing steel by experimental modifiers.
Sr and REM) provides a significant reduction in the contamination of steel by NMI of all types as a result of the effect on the properties and behavior of NMI.
Conclusions The use of complex microcrystalline modifiers produced by NPP Technology LTD provides: - more complete deoxidation and an increase in the degree of calcium absorption in comparison with that used according to the current technology of SC40 by 61.1-76.5% rel.; - increased degree of metal desulfurization; - reduction of steel contamination by oxide inclusions as well in maximum score as in average value; - a decrease in the content of CANMI in steel and a change in their morphology towards the formation of oxysulfide inclusions favorable in terms of increasing the corrosion resistance of steel.
