The Dragon Boat Festival, also known as the Dragon Boat Festival, Dragon Boat Festival and Tianzhong Festival, originated from the worship of natural phenomena and evolved from the Dragon sacrifice in ancient times. During the midsummer Dragon Boat Festival, Canglong Qisu flies up to the middle of the sky, which is the most “middle” position in the whole year. That is to say, “flying dragon is in the sky” in the fifth chapter of qiangua in the book of changes. Its origin covers the Ancient Astrology culture, humanistic philosophy and other aspects, and contains profound and rich cultural connotation. In the process of inheritance and development, it blends a variety of folk customs into one, and the festival customs are rich in content. Dragon Boat picking and rice dumpling eating are the two major customs of the Dragon Boat Festival. These two customs have been handed down in China since ancient times, and have been going on ever since.

Dragon Boat Festival, Spring Festival, Qingming Festival and Mid Autumn Festival are known as China’s four traditional festivals. The Dragon Boat Festival culture has a wide influence in the world, and some countries and regions in the world also have activities to celebrate the Dragon Boat Festival. In May 2006, the State Council listed it in the first batch of national intangible cultural heritage list; Since 2008, it has been listed as a national legal holiday. In September 2009, UNESCO officially approved its inclusion in the list of representative works of human intangible cultural heritage. The Dragon Boat Festival became the first festival in China to be included in the list of world intangible cultural heritage.

Recycled graphite carbon rod, simply said is roasted and pressed by graphite powder. Compared with graphite electrode rod, it has no graphitization in the process. Raw material is certainly different. The cost of graphite electrode rod is higer a lot. The density of recycled graphite carbon rod is higher than graphite electrode rod, respectively are 1.7 and 1.58. However, in the actual production, recycled graphtie carbon rod could not replace graphite electrode rod. With the development of science and technology, study and develop graphite application has a new develpment and discovery.
Compared with graphite electrode rod, conductivity of recycled graphite carbon rod is bad. If the requirement of resistance is more strict, graphite electrode rod should be used. If it is used for furnace, then recycled graphite carbon rod is more durable as it also has the heat resistant performance. The main reason is that the price is cheap. If it is used for stirring liquid, recycled graphite carbon rod could also be selected with good corrosion resistant performance. But if it is used for smelting process, graphite electrode rod should be used without no doubt. As it has strict requirement of physical index, recycled graphite rod could not be replaced.

In this artical, Raygroup graphite and carbon electrode will talk about the features of molten copper graphite crucible.
1. Density is between 2.2-2.3, the density is the density of the crucible of the world’s largest, high density making the crucible with the best thermal performance. Its thermal conductivity is better than the other brand crucible.
2. the glaze layer comparison
Aluminium graphite Crucible appearance there are four specially made glaze layers, coupled with dense material, both of which greatly improves the corrosion resistance of products, extending its life; Crucible made only one layer of cement on the surface. Extremely easy to damage the surface resulting in premature oxidation of crucible.
3. the contrasting comparison
Of ingredients all natural graphite crucible. Very good thermal conductivity. Made using synthetic graphite crucible, and in order to reduce costs and to reduce the content of graphite, due to technology reasons, manufacturers added a large number of clay to make it easy to shape. Significantly reduces the thermal conductivity.
4. packaging comparison
Crucibles for melting copper graphite crucibles are often used rope to tie wraps.

International Children’s Day is scheduled for June 1 every year. In commemoration of the leditzer massacre on June 10, 1942 and all the children who died in the war all over the world, we oppose the maltreatment and poisoning of children, and safeguard the rights of children.

In November 1949, the International Federation of democratic women held a council meeting in Moscow. Representatives of China and other countries angrily exposed the crimes of killing and poisoning children by imperialists and reactionaries in various countries. The meeting decided to take June 1 every year as the international children’s day. It is a festival set up to protect children’s rights of survival, health care, education and custody, to improve children’s lives and to fight against child abuse and poisoning. Many countries in the world set June 1 as children’s day.

Graphite processing Plant method: To speed up the development of new products and industrialization of graphite lay the foundation.

Graphite processing plant: Graphite is a allotrope of elemental carbon, and each carbon atom is connected with three other carbon atoms (in a honeycomb-shaped array of hexagonal) covalently bonded to form covalent molecules. Since each carbon atom emits an electron, the electrons are free to move, so the graphite belongs to the conductive body. Graphite is one of the most soft minerals. The use of graphite processing plants includes the manufacture of pencil cores and lubricants. Graphite processing plant is a good natural flotation, graphite processing plants are basically using flotation method for beneficiation. Because the size of graphite scale is one of the most important quality indexes, the selection method adopts multiple grinding and several other processes to select large scale graphite at the earliest possible time. Flotation commonly used collector for kerosene, diesel, foaming agent for No. Second oil, no. Fourth oil, adjustment agent for lime, sodium carbonate, inhibitors for water glass.

Due to China metallurgical steel industry is continuously growing, world lithium ion battery of is rapidly developing, which pulls on the needs of graphite materials; while industry, and government pay more and more attention on graphite strategy resources, which makes the price of graphite mineral rapidly climbe and reverse over 20 years situation that the price of other mineral is rising while graphite is constantly down. It not only makes graphite industry benefits constantly improve, but also makes some social funds constantly influx graphite industry.
Our country is rich of graphite, graphite industry for a long time within the low technical level of production, price competition, serious shortage of funding and technical inputs to the production of ore and mineral processing of low-end products, makes the industry’s prolonged slump. This situation leads to graphite deep process technologies and products in China lags behind developed countries, deep processing of resources is weak. It is not matched with the Chinese economy and the rapid development of science and technology. Present and for a fairly long period of time, protecting the invaluable strategic and scientific utilization of graphite resource graphite deep process development technology and product is a viable option for a cause.
Now, domestic already has a number of benefits of good (scales) graphite processing enterprises, flexible graphite in the largest enterprises are mainly located in Jiangsu and Zhejiang provinces, anode battery materials are mainly in Shenzhen and the Pearl River Delta and the Yangtze River Delta region. Flake graphite processing enterprises in Shandong have many homes, in Hubei, Henan, Fujian, Inner Mongolia, there are some enterprises.
