China Agricultural Machinery Industry News ] Modern agricultural manor is based on modern agricultural production, supported by modern tourism management service concepts and management methods, to meet the diversified needs of tourists and the transformation and upgrading of tourism consumption, relying on the natural and human resources of the manor In-depth development of tourism, leisure and holiday, health care, science and culture and other functions, and the formation of a variety of tourism industry clusters and tourism complex.
4 years later: 100 national modern agricultural estates will be built
Recently, the National Tourism Administration and the Ministry of Agriculture jointly issued the "Notice on Organizing the Establishment of the National Modern Agricultural Manor", and decided to organize the establishment of the National Modern Agricultural Manor within the national state-owned farms. It is planned to build 100 modern countries by 2020. Agricultural estate.
By 2020, 100 national modern agricultural manors will be built nationwide, basically forming a manor economic belt with scientific layout, reasonable structure, distinctive features and significant benefits. The establishment of a national modern agricultural manor is a concrete practice to improve the quality and efficiency of agriculture, realize the integration and development of the first, second and third industries, and promote the structural reform of the supply side of agriculture and tourism. It is an innovative business model and demonstrates the important focus of the new agricultural modernization with Chinese characteristics. It is an important measure to enrich tourism products and meet the diversified needs of consumers; it is an important carrier to promote global tourism, develop agriculture, build rural areas, and rich peasants, and become a new business card for the integration of rural tourism, which is important for building a well-off society in an all-round way. significance.
Aluminum gravity casting Introduction:
The gravity casting means the part is injected
by the earth's gravity. The generalized gravity casting includes sand casting,
Metal mold casting (permanent mould casting), investment casting, Lost Foam
Casting, Mud casting etc. The narrow meaning of gravity casting is metal mold
casting (permanent mould casting).
The permanent mold casting is modern
technology that the mould made by heat resistant alloy steel.
The metal liquid generally injected into the
gate by manual. Full of cavity depend on weight of liquid metal, exhaust, cool,
open mould and get products.
Process flow: smelting, filling cavity,
exhaust, cool, open mould, heat treatment, downstream processing.
The characteristics of the aluminum gravity
casting:
1. Less casting porosity, heat treatment can
be performed. The strength of the product can be improved greatly after heat
treatment, better than Die Casting Parts.
2. Product density is low, molding depend on
the liquid weight, the density of the product is lower than die casting parts,
its strength is slightly worse, but the elongation is higher.
3. The product surface finish is not high. Easy
form similar blasting pit on the surface of casting products after cooling
contraction.
4. Slow filling and low production efficiency,
the production efficiency is only about a quarter compare the high pressure
casting, caused the product cost is high.
5. Mould life is longer than die casting
mould, and mould cost is low also.
6. Process is relatively simple.
7. Not suitable for production of thin wall
parts.
