Graphite and cold stack

WatereoledgraphiteModer-Fedreactor with graphite as a slow neutron reactor with graphite as a chronic agent and water as a cooling agent. In the early days of the development of the nuclear industry, graphite and cold stacks were mainly used to produce nuclear weapons installation -钚, 氖, etc. This heap is generally fuel with natural uranium metal components. Uranium 235 in the natural uranium in the pile absorbs neutron reactor in neutron and releases neutron and energy. These neutron parts are used to maintain chain nuclear fissure reactions, and some are absorbed by the uranium 238 in natural uranium and converted into it to converted into it into. 钚 239 and other 素 isotopes. Structural graphite and cold stacks use nuclear pure graphite masonry as a chronic agent and reflective layer. There are two or three thousand horizontal tunnels (horizontal piles) or vertical tunnels (vertical piles) in the graphite masonry. Inserting graphite sleeves in these holes, aluminum alloy crafts pipe

It is critical to properly clean up graphite molds

Like other objects, graphite molds must be cleaned up after a long -term application. This is also a key factor in carrying out maintenance of graphite molds, and after cleaning up, the next manufacturing can be carried out immediately. As a result, the cleaning of graphite molds is very critical.If you want to achieve good practical effects and improve work effectiveness, proper operation steps are also crucial. During the entire process of cleaning the graphite mold, professional equipment maintenance management is created in the connection between the requirements and the actual operation. In order to complete the cost benefits, you must pay more attention when cleaning up. Especially for the different positions of graphite molds, the selected cleaning method is also likely to have a difference.Properly grasp the cleaning method of graphite molds and operate in accordance with the actual operation, which can increase the use period of the machine and equipment at a very large level

How to choose the scale of scales graphite size

Scales graphite has good conductivity and thermal conductivity. It is widely used in sealing, lubrication, metallurgy, chemical industry and other industries. Different industries have different requirements for the specific parameters of scales graphite. Choosing the correct graphite graphite is closely related to its effect. Today, I will explain the correct method of choosing the graphite size of the scale:1. The effect of scale graphite particle size on expansionThe degree of particle size on the expansion of scales also has a certain effect. After experiments, the expansion rate of scales graphite is directly proportional to the particle size of graphite. The expansion graphite has a rich pore structure. The smaller the grain size of the graphite. The smaller, the lower the expansion coefficient, and vice versa. Therefore, in the fields of sealing and fire -resistant coatings, large -scale scales should be selected as materials.2. The effect of scale graphite particle size on smo

Types and prices of scales graphite powder

There are many types of scales graphite powder. Scales graphite powder is a major type of graphite powder. Different types of scale graphite powder. The price of scales graphite powder is different. The scale graphite powder can be divided into high carbon scales graphite powder according to the amount of carbon. Mid -carbon scales graphite and low -carbon scales graphite powder. The higher carbon -containing scale graphite powder, the larger the scale of the scale graphite powder is industrial.The application range of high -carbon scales graphite powder is relatively wide in industry. High -carbon scales graphite powder uses high -quality natural scales graphite as raw materials. The carbon content of high -quality natural scales is very high. Increase the carbon content of scales graphite powder, and under the same factors such as granularity of high -carbon scales graphite powder, the price of high carbon scales graphite powder is higher than the price of carbon scales graphite, lo

Maintenance and upkeep of graphite crucibles

The graphite crucible must be strictly protected from moisture and must be stored in a dry place or on a wooden frame. When handling graphite crucibles, it is important to handle them with care and prevent them from falling or shaking. Before using them, they should be baked in a drying equipment or by the furnace to raise the temperature to 500 ℃. The graphite crucible should be placed below the surface of the furnace mouth to prevent wear and tear on the furnace cover. When adding materials, it should be based on the solubility of the crucible, and too much material should not be added to prevent tightening the crucible. The furnace outlet and crucible clamp should conform to the shape of the crucible, and the clamp in the middle should prevent damage to the crucible due to stress on the department. When removing slag and coke from the inner and outer walls of the crucible, it should be gently knocked to prevent damage to the crucible. A suitable distance should be maintained betwee
