In an electrochemical cell can be identified two electrodes the anode is being oxidized and the anode is reduced, when it comes to the anode polarized elements is the positive electrode and the cathode the negative electrode .. Graphite is a variety of coal, which forms three covalent bonds to 120 degrees, black and shiny metal used in the formation of electrodes because it is a semiconductor which increases their conductivity as temperature increases identified at room temperature conductivity low and the high temperature which melts what is’ immersed in the iron ore and scrap melt achieved without the destruction of the graphite electrode can be enriched with potassium to enhance its conductivity Usually graphite electrode are used in electric furnaces for pig iron processing and / or Scrap The process begins with the arrival of previously classified scrap the Aceria, here is inspected and then is cut or broken into more small pieces which are transported to the melting pot casting, after determining the amount to be fused proceeds to place two or three depending on the case and then using a high voltage transformer arcing occurs between the two electrodes which melts the scrap, at this time qualified personnel necessary to enter a probe to verify the composition of the laundry and if necessary proceed to the respective additives, it is necessary to emphasize that the use of blister is common to facilitate the separation of impurities by the readings of the probe passed the stage of refining.

Depending on the application, the casting becomes specific forming processes such as making billet or miscellaneous items produced by Rolling. Graphite electrodes are very fragile so its replacement is carried out very specific procedures assisted in some cases breaking them in the process involves great losses rather than their cost, by the time it takes to change seriously affecting the continuity of process. The transport of material takes place in the oven with the aid of special vehicles usually powered by electricity, the operators of these (picks) should be especially careful not to hurt the furnace when carbon (graphite) are very fragile as said replacement may delay the production significantly, it is usual to find scum removers vehicles also equipped with hydraulically commanded spoons. Currently there are several manufacturers of these items usually do via carbides in some cases using to increase their durability.

The economic effect of the introduction into the production process of electric motors and frequency inverters soft starters (soft starters) is achieved by the following factors: energy savings in pump, fan and compressor units up to 50% – 60% due to capacity control by changing the motor speed as opposed to regulation of way on / off, etc.; increase product quality, increasing the volume of production and productivity of manufacturing equipment, increasing the service life of process equipment due to the improvements of the dynamics of elektroprivoda.Pri choosing the model of the frequency converter should be based on a specific task, which should solve the actuator: type and capacity of the electric plug, accuracy and range of regulation speed, accuracy to maintain torque on the shaft of the motor design (dimensions, weight). When you work with a standard induction motor inverter should be selected with the appropriate capacity. If you need a great starting point or a short acceleration / deceleration time, select the frequency converter is a step above the standard. Examples of specific application of the frequency elektroprivodNa water pumping stations: The frequency converter is installed between the supply network and an electric motor to provide feedback. In the pressure manifold at the outlet of pump unit installed pressure sensor. Smooth regulation of frequency converter and the high accuracy of pressure in water supply networks can save energy up to 60% and leads to savings of pumped water, essentially eliminates hydroblows increasing the service life of pipes and valves.

When tobacco leaves begin to fall off the villi, it is time to harvest. Lush green mugs, maturing, lighter, becoming yellowish, like an old paper. Garlands of tobacco leaves hanging on the wire as drying pictures on the ceiling laboratory. In the stuffiness of the drying sheds on the sheets show through all shades of brown, tan or beige. As in sepia. And if it really were pictures, they would document the special southern life. On They would be etched portraits of landowners and the laborers, peasants – guajiros Twister and cigars – tabakero: swarthy faces on dark skin races applications, the perfect harmony of ideas and material.

Leaf by leaf, each high bush would have become one of the family tree of nicotine dynasties. Such as family Torano, people tobacco. Cuba is far away, near Cuba. This is how you look. Santiago Torano looked across the ocean. Blinked, probably on the sharp glossy silk Atlantic under the sun, repeating the idea of the route of Columbus.

On concepts of physical geography the way from point A to point B was not really close. But the prospects for opening up to the young Spanish golodrantsu from the sands his impoverished fishing village, it would seem only a brilliant painter, marine painter. If you are ambitious, the coast of Asturias, the beginning of the twentieth century can not be the start of a great life plans. And in the former colony, where more Cortez shipped its Mexican gold galleons fortunate compatriots Santiago and enterprising competitors, gringo forged young capital, and this hindrance could hear the ringing of the ocean to the ears of aspiring European boys. Santiago came to Cuba when he was eighteen or nineteen.

Protective shutters – shutters are webs of lamellae, or, in other words, profiles. Cloth roller shutters moving up and down the rails and rolled into a roll, reeling on the shaft, which is located in a protective box. Management options, roller shutters can be divided into two groups – manual and automatic, or mechanical and electrical. Mechanical or manual control includes a number of mechanisms, such as: tape management, trosikovy gear, cardan, retractable mechanism. Anyway, all the devices of the mechanical control of steel rolling shutters require the application of certain physical effort that distinguishes it from management automatically. When the electric motor control is inside the shaft, and the protective shutters controlled by a switch, when pressed on which they fall or rise. When deciding how to manage protective shutters should consult with a specialist, which accurately calculate the ratio of the mass structure and mode of administration and on the basis of future operating conditions of roller shutters, will pick the best option.

Since in any case when you install shutters it's not just about protecting the building, but also about the comfort, that is, to reduce time and effort. For example, automatic control will be the best solution for buildings that have steel roller shutters protected the windows of the first floor. It could be offices or houses. In this case, the touch of a button, switch or remote control, you can manage all roller shutters in the room. Electric drive also is perfect for control of steel rolling shutters that are installed as a gate in your garage.

Xenon light on his range is as close to daylight. The fact that the human eye sees best in daylight. Nature created man so that his vision was most effective in those conditions in which he lives. Sunlight – the normal conditions under which the eye feels comfortable. If the light is different from the sun, the eye muscles work harder and faster to get tired.

Daylight roughly corresponds to the color temperature 5500K, the maximum temperature is the same halogen lamp – 3200K (deviation from the norm for more than 40%). Normal life xenon lamp about 3000 hours, Halogen – no more than 400 hours. This is due to the fact that the longevity of a xenon lamp is connected directly with the time of "aging" of the gas (which is almost always the order of 3000 hours). Durability is galogenki depends on the filament, which in turn is subjected to mechanical stress (and therefore a Halogen bulbs burn out frequently because of the strong shaking that xenon can be no in principle). How to choose a xenon lamp? Quite recently to carry out the replacement of regular halogen lighting to xenon was very problematic and / or costly operation. It was possible to replace the supplied lamp assembly on the xenon, which is expensive, or redo seat tube in the headlamp under the cap xenon lamp D2S or D2R.Na Today it became possible to convert any halogen lamp under xenon light without alteration seat tube in the headlamp.

This was made possible with the advent of new xenon lamp socket, adapted to the halogen lamp cap H1, H7, H4, HB4, etc. Now the remake of 'halo' to 'Xenon' reduces to the usual replacement of lamps and to install next to the headlamp unit firing. Externally and internally set to an alteration looks just like factory equipment. When Selecting a color temperature xenon lamp to keep in mind that the most optimal for the human eye temperature 5500 K. In addition to aesthetic considerations, it should be noted that the higher the color temperature, the less effective xenon headlights in poor visibility conditions (fog, rain, wet asphalt).
