As we all know, needle coke is a high-quality raw material for producing high-power and ultra-high-power electrodes, anode materials and other high-end carbon products. Graphite electrodes made of needle coke have strong thermal shock resistance, high mechanical strength and good oxidation resistance. Low electrode consumption and high allowable current density. Needle coke can be divided…
Faced with the rising trend of imported raw materials,how will the game between buyers and sellers be deduced?what impact will the centralized release of new production capacity of domestic needle coke in the second half of the year have on the market? In terms of import and export,China’s total export of graphite electrodes in January-November…
1. In recent years,the state has resolutely banned the floor bar steel,resulting in a sharp drop in scrap steel prices,many new electric furnaces have been built in China,which has led to a large increase in the use of graphite electrodes.at the same time,under the pressure of environmental protection,many electrodes manufacturers that do not meet the…
According to different production requirements,there are different requirements for the design and manufacture of equipment.the basic requirements Should be considered in the design It has good thermal conductivity so that molten steel can be rapidly condensed and formed. It has good wear resistance to extend the life of the mould,reduce the maintenance workload and replace…
Why CrZrCu copper mould tube has a long life CrZrCu alloy is strengthened by adding a small amount of chromium and zirconium,forging and heat treatment under the condition of keeping excellent thermal conductivity and electrical conductivity of pure copper,the strength and hardness of the alloy are much higher than those of pure copper and copper-silver…
Copper mould tube is the core component of continuous casting machine, which undertakes the role of molten steel solidification. The quality of mould copper tube not only has a great impact on slab yield and quality, but also has a greater impact on the service life of copper tube itself. During the continuous casting process,…
At present, there are two types of mould lubricants: mold powder and oil (rapeseed oil), undeveloped countries, India, etc. Copper mould tube lubrication can reduce the resistance of billet drawing and improve heat transfer by filling air gap with lubricant. It can prevent the bonding between billet shell and inner wall of mould, improve the…
What is Copper Mould Tube? The Copper Mould Tube is an accessory for the cast steel continuous casting machine. The Copper Mould Tube is one of the core equipment of the continuous casting machine, which is directly related to the quality of the continuous casting billet. What is the role of the Copper Mould Tube?…
As the molten steel is cooled in the mould, the blank shell of a certain shape is formed. With the continuous downward movement of the casting blank, the temperature also decreases and contracts, and a gap is formed between the mould and the blank shell, which is called an air gap.The existence of air gap…
