Drawable resources. A drawable resource is a general concept for a graphic that can be drawn to the screen and which you can retrieve with APIs such as getDrawable (int) or apply to another XML resource with attributes such as android:drawable and android:icon . There are several different types of drawables:
– Input: Ingot – Output: heated Ingot • Rolling – Input: Heated Ingot – Output: bloom, billet or slab • Cold Rolling – tight tolerance, better surface and mechanical properties • Hot Rolling – above recrystallization temp. (450C for Al alloy, 1250C for steel alloy and 1650C for refractory alloy) converts the cast structure to ...
Radial–axial ring rolling is a hot forming process used to produce seamless rings. The first ring rolling mill which was able to produce rings without welding was, according to, erected in 1863, whereas stated that in 1849 it was Alfred Krupp who already initiated first trials to produce seamless rings and constructed a first rolling mill in 1853/1854.
2.1 Experimental set up. A Hille-100 rolling mill with rolls of 225 mm diameter and 254 mm length, driven by a variable speed DC motor of 75 horse power, was used. The maximum rolling force, torque and speed are 1500kN, 13kN-m and 70 rpm respectively. The sensor roll nitrided surface hardness is 65 to 70 HRC.
Illustration of the different types of gears available. Image Credit: Tewlyx/Shutterstock. Gears are toothed, mechanical transmission elements used to transfer motion and power between machine components, and in this article, we discuss the different types of gears available and how gears work. Operating in mated pairs, gears mesh their teeth …
EDM output Determines the output type for the Binary Distance Map↑, Ultimate Points ↑ and Voronoi↑ commands. Set it to 'Overwrite' for 8-bit output that overwrites the input image; '8-bit', '16-bit' or '32-bit' for separate output images. 32-bit …
(Input Angle = 15°) • Output profiles are shown below for input angles of 0°, 11°, and 15°. The camera imaged the output beam profile 5 mm from the output of the fiber. All images were acquired with a spinning diffuser to reduce the spatial coherence and demonstrate the underlying profile from each configuration.
24.1.16.1. Add geometry attributes ¶. Computes geometric properties of the features in a vector layer and includes them in the output layer. It generates a new vector layer with the same content as the input one, but with additional attributes, containing geometric measurements based on a selected CRS.
For other dimensions, they are in input order. simplices ndarray of ints, shape (nfacet, ndim) Indices of points forming the simplical facets of the convex hull. neighbors ndarray of ints, shape (nfacet, ndim) Indices of neighbor facets for each facet. The kth neighbor is opposite to the kth vertex. -1 denotes no neighbor. equations ndarray of ...

Abstract A rolling mill process control system calculates the setup for the mill's actuators based on models of the technological process.
For integer inputs, the default is float64; for floating point inputs, it is the same as the input dtype. out ndarray, optional. Alternate output array in which to place the result. The default is None; if provided, it must have the same shape as the expected output, but the type will be cast if necessary. See Output type determination for more ...
Input and output locking rings 26, 28 are provided on the input and output sides to mate the ring gears 18, 20 to the pinion sub-assemblies 22 and lock the entire assembly 14 together. When assembled, the drive is rigid, possessing the ability to support thrust, radial, and bending loads, as described further below.
an upward curved shape that helps to retain a certain minimum amount of material under the rollers. The grinding table is further – at the periphery – equipped with an adjustable dam ring (Figure 4). A higher dam ring will result in a thicker grinding bed corresponding to a longer retention time of the material on the grinding table. The

For rolling mill machines, the operation status of bearing has a close relationship with process safety and production effectiveness. Therefore, reliable fault diagnosis and classification are indispensable. Traditional methods always characterize fault feature using a single fault vector, which may fail to reveal whole fault influences caused by complex process disturbances.
The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 90 percent. Because the process relies on large number of small forming steps, the result is tube or pipe that has nearly homogenous material characteristics. It is suitable for every metal.
An O-ring seal is used to prevent the loss of a fluid or gas. The seal assembly consists of an elastomer O-ring and a gland. An O-ring is a circular cross-section ring molded from rubber (Figure 1-1). The gland — usually cut into metal or another rigid material — contains and supports the O-ring (Figures 1-2 and 1-3).
These are used in the cylinders of machinery, rolling mill rolls, and the main shafts of machine tools, where thin-walled bearings are required. In the main shafts of machine tools, the radial inner clearance is adjusted by pushing the …
Let's say we want to predict the output for an input of 30. The actual output should be 30 x 15 = 450. Let's see what value do we get. First, we need to convert our test data to the right shape i.e. 3D shape, as expected by LSTM. The …
Based on the actual radial-axial ring rolling production conditions, the range of k is from 0 to 1 [7].

Hot rolling breaks the grain structures and destroys the boundaries, giving rise to the formation of new structures with strong boundaries having uniform grain structures. Starting materials such as blooms or slabs at an elevated temperature flow from the continuous casting process directly into the rolling mills.
