Operating Techniques for Graphite Crucibles

Graphite crucible is a very excellent smelting tool that has been praised by people in the metal smelting industry. Its usage method is simple. Below, we will introduce some matters that need to be mastered when using it.The main uses of graphite crucibles include evaporation, concentration or crystallization of solutions, and burning of solid substances. It should be noted that although graphite crucibles have strong temperature adaptability and can be directly heated, they cannot be suddenly cooled after heating. If necessary, use crucible pliers to remove the crucible instead of using technical means to quickly cool it. Because it is directly heated and the heated contents are metals with extremely high dissolution temperatures, the required energy and safety requirements are relatively high. Therefore, during the heating process of the crucible, it is necessary to have a stable environment to ensure the safety and effectiveness of the operation. In general, manufacturers choose to

What are the characteristics of pre -immersed graphite carbon board

What are the characteristics of pre -immersed graphite carbon plates, pre -immersed graphite carbon plates, high -quality graphite carbon raw materials, and organic chemical complexes with strong alkali resistance. It is made of compression, vacuum pump pre -immersing, and high -temperature thermal treatment methods. It has an extraordinary acid resistance and thermal resistance. It is the idealized lining raw material for machinery and equipment such as ammonium sulfate reflection slot and ammonium sulfate storage slot in the chemical manufacturing industry. Category of non -transparent graphite. Pre -immersed graphite with anti -corrosive coatings to block its surface and internal pores, and then carry out the heat treatment process to make the epoxy resin dry. Compared with graphite, the impact toughness is improved, and the heat transfer performance will not change. Different from the pre -immersed epoxy resin, there are different types of phenolic resin thermal immersion zinc gra

Production process of electric carbon products

(1) Raw materials. The raw materials used in the production of electrochar products include carbon and graphite powder, metal powder, and binder.(2) Calcination. The calcination of petroleum coke used in the production of electric carbon products generally adopts electric calcination.(3) Ingredients. According to the performance requirements of electric carbon products, 4-5 solid powders are used as ingredients.(4) Material mixing. Mixing mainly uses dry mixer, dual axis stirring knife mixer, pressure mixer, and continuous mixer.(5) Rolling sheet. The paste prepared with coal tar pitch as the binder needs to be processed by rolling to ensure the uniformity of the mixing of various materials.(6) Grinding powder. Grind the kneaded material and rolled sheet material to obtain pressed powder.(7) Pressing. The forming of electric carbon product blanks is generally done by molding, and the forming equipment includes hydraulic presses and mechanical presses.(8) Heat treatment. Heat treatment

Many elements of the destruction of graphite molds

There are two methods for burning the graphite molds for the destruction of graphite molds: resistance wire heating method and high -frequency electromagnetic sensing heating method. We know that when the resistance wire heating method is burned, the outer mold temperature is low, and the blade and core mold temperature is higher. The temperature is unevenly decided to decide the part where the mold is destroyed.1. Surface air oxidation and cracks: Because there is no recovery atmosphere during the entire process of burn, the graphite and gas are directly contacted, and it is difficult to avoid the surface air oxidation at high temperature. The higher the temperature, the faster the air oxidation rate; The mold is slowly consumed, leaving only a part of carbon and gray, and stones can be found on the spot on the spot. After a period of time, the surface of the mold will cause porosity and charcoal.2. Fracture: The reason for this kind of destruction is that the gear board of the golde

Introduce the asphalt rubber pendant penetration processing process of graphite board

The general operating process of graphite immersion is after being loaded into the product, first vacuum packaging (gas in the gas in the pores in the pores of the product) and then put it in the impregnation agent to submerge the product, then pressure it to the liquid level, so that Essence It is used for different intentions, and the standards of impregnation agent processing process are not thorough. Below, I will introduce the asphalt rubber mud impregnation processing process of graphite board in detail.The whole process of processing the processing technology of asphalt rubber -soaking small graphite board, electrode connector and its graphite anode board:First of all, the semi-finished processing surface of the graphite board was burn, and then put it into the product box and put it in the temperature of about 4 hours in the temperature of about 240-Soot. After the heat, the product is quickly installed into the impregnation tank with the iron frame (the immersion can be heate

What are the processing methods for different types of carbon materials

(1) Processing of graphite electrodes. The processing of electrodes can be divided into three processes: boring and rough flat end faces, turning outer circles and fine flat end faces, and milling threads.(2) Processing of conical joints. The processing of conical joints can be divided into six processes: cutting, flat end face, turning conical surface, milling thread, drilling and installing bolts, and slotting.(3) Processing of cylindrical joints. The cylindrical joint can be divided into three processes: cutting, flat end face, and thread milling.(4) Processing of carbon blocks. The processing of carbon blocks mainly involves flat six surfaces.(5) Processing of special-shaped carbon materials. According to user needs, perform cutting, turning, grinding, boring, slotting, and planing. For products with special requirements, more precise processing is required after normal processing.

How does pungeable graphite produce?

Because graphite is a non -polar material, it is difficult to use the small polar organic or inorganic acid intercourse alone, so oxidant is usually used. The chemical oxidation method is generally soaked in the solution of the natural scales in the solution of the oxidant and plug -in agent. Under the action of a strong oxidant, graphite is oxidized, making the macromolecular molecule of the graphite layer into a plane macromolecular with a positive charge. Due to the extrusion effect of the iconic charging between the plane macromolecules with a positive charge, the spacing between the graphite layer increases, and the plug -in agent is inserted between the graphite layer and becomes a graphite. When heating at high temperature, puffed graphite will quickly shrink, and the contraction multiple is as high as tens to hundreds or even thousands of times. The apparent volume of shrinking graphite reaches 250-300 ml/gram or more. The contracted graphite is worm -like, with a size of 0.1
