In recent years, the rapid development of mold industry, graphite materials, new technology and increasing mold factory constantly impact the mold market, graphite with its good physical and chemical properties gradually become the preferred material for mold production. Graphite mold cleaning is a key process in the maintenance of graphite mold, and it is also a bottleneck

2021 is the 100th anniversary of the founding of the Communist Party of China and the first year of the 14th five year plan. It is very important to do a good job in all kinds of work during the new year’s day and Spring Festival. China’s novel coronavirus pneumonia should be guided by Xi

1. The difference between graphite and graphite blocks is the appearance of solid graphite, more commonly made of synthetic graphite, graphite mold and so on. It also uses small graphite blocks made from flake graphite, such as carbon brushes. Most of graphite is powdered, such as soil graphite, flake graphite and so on. 2. Graphite shape characteristic

Use tools 240# ~ 320 sandpaper, wire brush, apron, rain shoes, safety helmet Pre work preparation 1. Wearing aprons, rain shoes, gloves, safety helmets and gloves must be cleaned after water, acid and water. 2. 109 sodium hydroxide solutions are prepared in the cleaning tank which is intended for cleaning graphite anode plates. 3. Uncover

The thermal field is the core part of the vacuum resistance furnace. Its quality directly affects the performance and operation cost of the furnace. The graphite heat field of most vacuum resistors mainly consists of four main parts: the heater and the connecting part, the heat insulation component (or the reflection screen), the heat field support

Main performance of graphite heater The service life of the heater is affected by the oxidation rate and volatilization rate of graphite. When the vacuum is 10–3–10–4 mm Hg column, the service temperature should be below 2300 C. When the atmosphere is protected (H2, N2, Ar, etc.), the temperature can reach 3000 degrees Celsius. Graphite can
