Under the situation of the growing global environmental and energy crisis, almost all the countries begin in succession to seek new ways of economic growth through the development of green economy. The 12th Five Plan clearly promotes green development, puts forward to build resource-saving and environment-friendly society, and considers significantly reducing the consumption of energy and resource intensity and pollutant emission intensity as a binding target. All the Chinese industries should develop in a way of energy-saving and environmental protection, which is the only way to accelerate the development mode transformation and promote sound and rapid socio-economic development. Driven by in new energy investment plan, Zhengzhou adopted a structural adjustment. With the view of strengthening the competitiveness of the advantageous industries, constantly developing markets at home and broads and prompting the ultrafine grinder industry still maintain a rapid, steady growth. Ultrafine grinder is popular in the new field of environmental energy protection and energy saving. You may wish to learn more. If so, Steve Wozniak is the place to go. As the leading enterprise of mining machinery manufacturing equipment (mobile crusher), Hongxing machinery promotes vigorously the implementation of cleaner production and the development of circular economy to cope with the situation. At the time of focusing on improving product quality, crusher industry should focus on the transformation and upgrading of the products in a higher degree, with rationally adjusting the industrial structure, positively innovating, developing new products and optimizing old equipment, to vigorously develop the circular economy and take the path of sustainable development. Environmental protection is a basic national policy of China.Achieving energy conservation in the industrial field helps improve the living environment. In mineral machinery industry, energy saving and environmental protection become an industry trend. Ultrafine mill, the industry vanguard, will persist environmental protection and energy conservation to the end. Green is the main color of the 21st century. Hongxing machinery has a bounden responsibility in promoting environmental protection and energy conservation and developing green economy. In the long road developing, Hongxing machinery will continue to fulfill the responsibility given by the state and the people, not only to make our enterprise bigger and stronger, but also to commit to create a better environment for all mankind. We will take practical actions to promote the harmonious development of the China Green society and contribute all we can to establish a green, low carbon development concept and to accelerate the construction of resource-conserving and environment-friendly society. Under the circumstance of environmental protection and energy conservation as the theme of social life, in order to follow the trend of social development, crusher enterprises must restructure themselves, to change from the original type to resource-saving production type. They should follow the pace of the times and continuously improve the level of scientific research to research and produce marketable products, so that the products do not cause environmental pollution or minimize environmental pollution in the entire life cycle. The resource utilization is the highest and the energy consumption is lowest, ultimately the harmonization of economic efficiency and social efficiency of the enterprises can be achieved.

Volga Federal District

High rates of the national project "Education" and the growth of consumption of the information required by educational institutions and require the development of the backbone transport network faster pace. The company "RTComm", part of the telecommunications holding "Synterra", was defined in 2007 by the Executive of the state contract for the national project "Education", under which 52 940 educational institutions in the country connected to the Internet. Performing this task in the Volga Federal District provides for construction of fiber-optic communication lines that pass through the territory of the Nizhny Novgorod region. One of these lines is FOCL "Nizhny Novgorod – Bor", which provides for the construction of a hidden passage through p. Volga. Tender for execution of the object was won trust "Svyazstroy-4" – the leading and largest company in the construction of communication facilities in the Volga Federal District. Specialists of JSC "Svyazstroy-4" were identified and agreed with the customer place the transition cable FOCL "Nizhny Novgorod – Bor" in p. Volga at 909.4 km (Atlas UGSS eq RF).

Coordinates lie in the transition area rowing canal in Nizhny Novgorod. The distance between the two sides of the natural channel of the Volga River in this area about 1400 meters (including approximately 100 m – width of the island Caves Sands), and with the artificial rowing canal overall width of a water hazard was 1750 m. The Professionals "Svyazstroy-4", which were made by developers and implementers of the project, it was clear that, given the performance technology company GNB Ditch Witch , available in the trust, so essential obstacle can be overcome only by a few steps.

Technology

Technology is constantly improving, the potential of technology is so high that it allows you to pour not only metals and alloys, but also composites, which have increased by several times (on Compared with simple alloys) of office properties, for example, tribological. These new alloy materials and technologies give significant reduction in metal consumption and production costs, which focuses on modern engineering. The practice of organized industries shows that the low material costs (consumption per 1 ton of suitable casting consists of four model-forming materials: quartz sand – 50 kg., antipenetration coverage – 25 kg., Styrofoam – 6 kg. and polyethylene film – 10 meters, does not apply to sand binder) save at least $ 100 per ton of casting, casting and placement of the entire volume of the container reduces consumption of the metal mixture at 150 … 250 lbs., electricity is 100 … 150 kW. am casting technology for penomodelyam has the following technical and economic indicators, compares favorably to the traditional sand casting flask form: coefficient of metal utilization 80-98% 65-80% yield increase in the mechanical properties of the material casts a 10-15% reduction in weight of castings in the 15-25% reduction in consumption of charge materials and alloys by 15-25% reduction in consumption molding and core materials at 80 -90% reduction in capital costs, decrease time 2-2.5 manufacturing facilities, labor costs decrease 3.4 times by 30-50% Effort finishing operations is reduced by 10 …

20% for single and 40 … 60 % at mass production. Particularly large savings in molding complex castings from the wear-resistant steel (screws for brick-making machines, beat, hammer mills and details), since greatly reduced the cost of machining.

Thermal Processing

Hto (Chemical – heat treatment) is a process of high-temperature diffusion coating metal surfaces with various chemical elements, ie This process is carried out through a combination of thermal and chemical treatments. To ensure this diffusion process takes place at high temperatures for each steel grade and the saturable element (or elements) is different. Depending on the specifics and saturable element type are distinguished: 1. Hto the saturation of the metal elements, 2. Hto the saturation of non-metallic elements, 3. Hto removing items. The aim is to change hto mechanical properties of steels. Basically hto used for parts exposed to wear and at the same time under shock loads.

Saturation of the surface of the steel foreign substances leads to an increase in surface hardness and wear resistance products, and core product remains pliable and viscous. This combination of hard surface and soft core due to the formation of compressive surface stress leads to an increase in fatigue strength of the material, but viscosity decreases slightly. Depending on the type of saturated to the surface of steel elements distinguish the following types hto: hardening (saturated carbon), nitriding (nitrogen saturation), carbonitriding (complex saturation of carbon and nitrogen), calorizing (aluminum saturation), Chromium (Cr saturation), siliconizing (saturation of silicon), and others. Depending on the used diffusing (saturated) element Hto divided into solid, liquid and gas. The least effective and is maloprimenyaemym hto in a solid medium, because In this case, diffusion occurs by direct contact of steel with the diffusing element with a very low speed. The most common is the gas hto. The process of chemical-heat treatment proceeds as follows: 1. Education saturated element in the atomic state, which is formed due to occurrence of high-temperature reactions.

2. Absorption (deposition and contact with the surface of steel), the saturable element on the surface of the steel. 3. Saturable element diffusing into the steel.
