For serial production of castings available semi-automatic, cycle of foam models which account for about 2 … 3 min. and are “taken” from the packaging industry, where they involve the production fancy packaging, light packaging, as well as decorative, sound and thermal insulation panels, decorative facade elements. Practice shows that this model of operating equipment in foundries of our country is the most busy and often operated in three shifts. Industrial areas: modeling, molding, melting, purifying have roughly the same size and are equipped with simple equipment (the most complex model is mentioned).

All molding is composed of dry sand backfill with the vibration of the container up to one minute without massive precision machines pressing, shaking, device assembly forms of traditional types of molding. The focus of attention transferred to production models – these “lightest toys” with the density of the material 25 … 27 kg / cu. m, which is typically “trust” feminine hands, often placing in the second and higher floors of buildings. Quality of the model basically determines the quality of the casting.

Cable CIP – Benefits 1. Reducing the voltage drop due to significantly lower reactance (an average of 0.1 ohm / km instead of 0.35 ohms / km), which increases the load in kW for the same line and same voltage dip or improves the quality of the transferred energy at the same load. 2.Umenshenie power line installation costs associated with cutting down a more narrow clearing in the forest areas, the possibility of using shorter poles (recommended distance to the ground for insulated wire is 4 m for bare – 8 pm) 3.Uproschenie process laying new lines, simple retrofitting of existing lines with bare wires on the line with self-supporting insulated wires. 4.Vozmozhnost installing additional parallel to the existing CIP to double the capacity of the network (which is unacceptable when using bare wires). 5.Vozmozhnost joint Laying on the same supports both SIP and high-voltage overhead lines 6-20 kV with bare wires or protected. 6.Vozmozhnost simultaneous mounting on the same phone line supports (0.5 m lower than wire CIP). 7.Rezkoe reduction (80%) of operating costs due to high reliability and trouble-free energy consumers, and there was no need to clear firebreaks in the process of operating the line replacement of damaged insulators. 8.Prostota assembly, the ability to connect new subscribers under stress, without shutting down the rest of the energy supply and as a consequence of shortening the repair and installation.

Reduction the risk of fires in wooded or brushy area in the fall to the ground wire. 9.Umenshenie safe distances from buildings and civil engineering (electrical, telephone, air-lines) that provides greater flexibility when installing. 10.Vysokaya security service – no risk of defeat at the touch of the phase conductors under tension; 11.Otsutstvie or slight sleet and fouling isolated surface wet snow wires. This is explained by the fact that PE is not a polar dielectric, and it does not produce any electrical or chemical bonds with them in contact with the substance. It is for this reason Wet snow is easily flows from the round surface of isolated PE wires. In the wire type A and AS wet snow can be retained in the grooves between the wires, being the root cause of fouling. 12.Povyshennaya safety zones heavy icing, glaze, reduction of wind loads on the supports; 13.Bespereboynoe electricity in case of failure of CIP to the supports.

Private consumers prefer pellets the best quality and price of grain is the highest and most attractive manufacturers. This type of grain is also called 'grains of the first class. " Pellets of lower quality are often called 'industrial pellets'. They may contain small amounts of bark (and sometimes up to 10% of the cortex, although the crust in Granules generally undesirable). The cost of 'industrial pellets' are much lower, and manufacturers tend to prefer the pellets' beads of the first class. " Industrial granules contribute to some extent the development of slag after combustion. Slags are not acceptable to the granules of class I, as they inevitably interfere with the combustion process. All types of fuel left 'ashes', which is a small amount of various metals and other substances.

Slags arise when certain types of metal melted and shaped stones. At the present time in different parts of the world, studies and experiments on how the raw materials of poorer quality (Producing slag) can be used for industrial purposes. Some obvious advantages of using compressed biofuels – burning in the boiler furnace is more efficient – when burning pellets / briquettes do not have a negative impact on the environment – the exhaust gases have a high pH-level, and therefore, there is a 'healing' effect, against the harmful effects of burning fossil fuels – in storage granules and briquettes do not cause allergic reactions – the production of pellets and briquettes of sawdust volume is greatly reduced – the production of pellets and briquettes should increase, so As the European Union has decided that for 2010 12% of energy should be derived from renewable fuels. Features and additional capabilities when using pellets, except for all the above advantages of pressed biofuels are the following: – the supply of fuel to the burner of the boiler can be easily made automatic – pellets can be used in small power plants for heating private houses and in average power boiler for heating offices, schools, etc., as well as a more powerful boiler – pellets used in Europe in the boilers of combined heat and power CHP to generate heat and electrical installations in medium and large capacity – pellet burners can be easily installed on boilers instead of waste burners for liquid fuel while maintaining high levels of automation – reduces costs transportation in many regions (their own, domestic fuel), unlike coal or oil – reducing moisture to 10 – 12% reduction in weight of the finished product, which affects the cost of transportation – uniformity and flowability Fuel can be used to fuel trucks for transportation of the tank – the ability to use simpler and more efficient combustion systems, furnace fuel can be stored for long periods without the risk of his decomposition – the power generated energy in a five times higher than in untreated wood on the basis of the trend to increased interest in new energy technologies, the availability of existing demand of pellets in the West, a real lack of competition manufacturers upgraded fuel products on the Russian market, the availability of inexhaustible resources of raw materials, allows us to conclude that organization in Russia the production of fuel briquettes and pellets is timely and relevant..
