Some related knowledge of mold processing

1. Use as conductive materialsWhen using an arc furnace or mineral heat electric furnace to smell all kinds of alloy steel, iron alloys or production stones (carbonized calcium), and yellow phosphorus, strong current passes through carbonic electrodes (or continuous self -roasting electrodes -that is, electrode paste) or graphite electrode introduction The melting area of the electric furnace generates an arc, which translates the electrical energy into thermal energy, and the temperature increases to about 2000 degrees Celsius, so as to meet the requirements of smelting or reaction. Metal magnesium, aluminum, and sodium are generally removed with melting salt electrolysis. At this time, the anode conductive material of the electrolytes use graphized electrodes or continuous self -baking electrodes (anode paste, sometimes pre -baking anode). The temperature of melting salt electrolytic is generally below 1,000 degrees Celsius. The anode conductive material for producing alkaline (sodi

Two ways of formation of scales graphite

The application of scales graphite in the industry is very widely used, and it plays a pivotal role. my country is one of the countries with rich scales in the world in the world. So how does the scales graphite ore formed? Two causes of biology, the following editors will explain the two formation methods of scales graphite for everyone:1. Bio -graphite biological causesBiological causes refer to the scales graphite directly from organic matter, commonly in marble, sliced rocks, or hemp rocks. Coal seams or carbon -containing sedimentary rocks can form scales graphite. It is the metamorphic mineral of graphite, which is made of organic or charcoal.Second, the non -biological cause of graphiteNon -biological causes refer to the reducing carbon out of CO and CO2. In the contact zone between magma rocks and limestone, scales are often produced. This is due to the decomposition of carbon dioxide by limestone and degenerate. The formation of mineral beds must concentrate and have suitable

Heating graphite

Graphite radiator (3K-SBP) is a brand new heat-conducting heat dissipation material with unique grain orientation, which is evenly conducted in two directions. Improve the performance of consumer electronics. The product is uniformly dissipated while providing heat isolation in terms of thickness. The molecular structure diagram of the thermal graphite sheet is as follows:The unique combination of heat dissipation and thermal insulation performance of graphite heat conductive solutions allows heat -conducting graphite to become an outstanding material option for heat management solutions. The thermal graphite plane has the ultra-high thermal conductivity within the range of 150-1500 W/m-K.The chemical composition of Thermal Flexible Graphite Sheet is mainly a single carbon (C) element. It is a natural element mineral. The film polymer compound can obtain a graphized thin film under high temperature and high pressure because the carbon element is non -metal. Elements, but there is a co

Mold graphite

The casting industry in the mechanical industry uses graphite materials as molds such as pressure casting, centrifugal casting, and hot squeeze of super hard alloy. It can use graphite molds as large as train wheels and small as small as precision parts. Graphite molds can be repeatedly used for multiple times. After the molding, the casting has a high degree of smoothness, and some can be used without further processing. The graphite material used for casting molds should be graphite with a dense texture, low thermal expansion coefficient, and good antioxidant performance. Graphite, which is used for casting with large casting size, can be composed of thicker particle size. It is used for casting small precision parts The graphite must be graphite with fine particles. The number of graphite used to make molds in China is large. In 2005, it was continuously cast about 1500T with graphite and sintering molds were estimated to cost 4000T. Table 4 is the specifications and technical perf

What kind of crushing of graphite blocks can be divided into?

The crushing of graphite blocks can be divided into three items, do you know? Let's take a look at it together!1. Pre -fragmentation (or crushing): This also refers to the crushing of block -shaped graphite block raw materials after entering the factory. Generally, it refers to crushing the block of the block of 200mm to 50 ~ 70mm. EssenceSecond, medium crushing: This also refers to the granularity of graphite block raw materials after forging to the particle size necessary for the seasoning. Generally, the block degree of up and down 50mm after the forging is crushed to 1 ~ 20mm.Third, fine grinding (or grinding): It is grinding part of the raw material of graphite blocks to 0.15mm or 0.075mm particle size below. Every time it goes through, the granularity of the raw materials has become smaller. The larger diameter of the large raw material before crushing is the ratio of the diameter of the larger block of the raw material after crushing, which is called a crushing ratio.

Graphite board antioxidant solution increases the period of use

Graphite boards are used in many industries, and due to their different advantages, future use will be more common. Old iron is very concerned about the use of graphite boards. The solution of the antioxidant solution of graphite board can reasonably increase the use period.After the formation of graphite board, it must be solved by antioxidantization. Generally, antioxidants are used, which is a thick liquid state. The ingredients are heat -resistant nano -ceramic particles. In the natural environment of air oxidation within 1300 ° C in the application temperature of the graphite board, its antioxidant actual effect is very good.
