The copper body can also be cast into the desired shape. If it is not needed somewhere, copper can be saved, and the flexibility of the shape of the hot surface can be maintained to the utmost so that the slag skin can be anchored and stabilized best. Corrosion and leakage mechanisms of cast iron cooling staves' Relatively, the temperature of the copper stave wall rarely exceeds 150 °C, and the possibility of thermal deformation is rather low. The development of copper staves began in the early 1970s and early 1980s. In the United States, Japan, and France, manufacturing methods focused on foundry casting, forging/drilling, or rolling drilling. However, all these types of staves require welding interfaces to seal the drilled or cast cooling water passages. In a 5-lap cooling stave system, 35 to 40 staves are installed per revolution. As a result, multiple welding interfaces are located in the furnace. Each interface is a potential leak due to fatigue stress. These manufacturing limitations have inspired the development of a new type of copper stave, which combines the flexibility of pouring with the reliability of leak-proof piping. The development of the alloy tube process The copper stave of the alloy tube process has been used for a long time in other metallurgical furnaces, and recently installed on several blast furnaces in Europe and South Africa. This manufacturing method is to integrate the seamless Monel tube of the slippery concrete into the cast copper to form a leakage-proof cooling water passage with a small pressure loss. Copper is used as a cast material because of its high thermal conductivity. Without a cross hole at the same time, there is no need for a welded interface, eliminating the risk of potential leaks. The analysis shows that there is an alloy structure between the two metals. During casting, the surface of the Monel tube partially melts. Steel poles are commonly used to carry several
types of electric power lines, distribution lines and lighting system. Distribution lines carry power from
local substations to customers. They generally carry voltages from 4.6 to 33kV
for distances up to 30 miles, and include transformers to step the voltage down
from the primary voltage to the lower secondary voltage used by the customer. A
service drop carries this lower
voltage to the customer's premises. Traffic Pole,Galvanized Steel Traffic Pole,High Quality Traffic Pole,Traffic light Pole Yixing Steel Pole International Trading Co., Ltd , https://www.yx-steelpole.com
