Precautions for use of graphite electrodes
1. According to the capacity of the electric furnace and the load of transformer, the grade and diameter of the electrode are suitable
2. When loading the electric furnace, the bulk charge shall be placed in the bottom of the furnace so as not to break the electrode. In the process of smelting, the lime should not be conductive. Large masses of objects are concentrated directly below the electrode, otherwise it will affect the electrode and even cause the electrode to break.
3. Attention should be paid to the position of the furnace cover. If the furnace cover is offset, the cover of the furnace will be blown on the lifting electrode, causing the electrode to be damaged.
4. When connecting the electrode, if the defect of joint bolt is found, the connection should be made after replacement
5. After the electrodes are connected, if there is a gap in the connection surface, it is important to find out the reason
6. The electrode should be used vertically.
7. The electrode holder shall be sandwiched between the upper and lower levels of the top electrode, and shall not be sandwiched between the warning line and the middle electrode. Otherwise, the electrode column is easily broken
8. The raw materials and production techniques of different manufacturers may vary. The physical and chemical properties of the electrode are also different, and it is recommended that the joints and electrodes produced by different manufacturers should not be used in a different way.

Currently, the global leader in valve mainly in North America, Japan and Germany, the world-renowned valve enterprises are mainly Emerson, IMI, Kitz Group, Flowserve, GE, Crane Company, Metso, Cameron (Schlumberger) and the KSB Group. These companies have complete product types and deep technical accumulation. They have established perfect production, sales and after-sales organizations all over the world, and have stable downstream customers. In a short period of time, it is difficult for companies to break the existing market structure.
After decades of development, China's valve industry has made great progress. At present, the number of valve companies in China ranks first in the world, and the level of valve production has also been greatly improved. The valve revenue has achieved a substantial increase. The main products of China Valve have basically met the needs of the domestic market. The complete set rate, complete set level and complete set capacity of the valve market have been greatly improved. The domestic valve has already had a certain revitalization foundation. However, China's valve industry is still dominated by small and medium-sized enterprises, only a few of the world's most influential and well-known valve companies such as Newway Valve, Sanhua and China Yuanda Valve.
Valve companies need to change the existing production relations to strengthen technological innovation. Faced with the increasingly serious problem of homogenization, the valve industry is now gradually falling into a vicious competition circle that cannot escape in the wireless cycle. In this grim situation, valve companies need to clearly understand that low-cost, low-tech valve products flood the market, not only disrupt consumer judgment and purchase desire, but also hinder the mature transition of the valve market. Therefore, if valve companies want to improve production efficiency, they must first change the existing production relationship, increase investment in modern production lines, and strengthen technological innovation. At present, valve companies must insist on innovation, structural adjustment of products, transformation of traditional products, and advance to high-end valves.
Valves are control components in fluid delivery systems that have functions such as shut-off, regulation, diversion, backflow prevention, regulation, shunting or overflow relief. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. In 2017, the global valve market is valued at 52,923.54 million US dollars. By 2025, the global valve market is expected to reach 69,982.43 million US dollars, with a compound annual growth rate of 3.55%.
