Q:What are the welding methods at the end of the thermocouple?: Argon arc welding type K thermocouple argon arc welding equipment consists of 5 parts, such as DC welding power supply, high frequency oscillator, welding gun, welding power supply and clamp. When welding, the cerium tungsten wire extending out of the welding nozzle is used as the negative electrode, and the welding thermocouple is fixed on the fixture as an anode. When the poles by high frequency and high voltage when the arc ignition function, using thyristor voltage control, arc intensity, under the protection of argon to cerium tungsten and generating arc discharge between welding thermocouple, high temperature generated by the arc melting end of the thermocouple wire into a ball. In order to facilitate the alignment of the thermocouple with the electrode, the work fixture and the welding torch can move in both horizontal and vertical directions. The welding torch is equipped with cerium tungsten electrode of diameter 1mm and 1.5mm, which is used for welding thermocouples of different diameters.

Q:How can food detect heavy metals and microbes?: Single sweep polarography, it is a kind of controlled potential polarography, the electrode potential is a linear function of time, by observing current oscilloscope. Potential curves, it is also called the linear displacement oscillopolarographic method, the detection limit was 0.085mg/kg.Two sulfur colorimetric method, the method used two sulfur hydrazone as chromogenic agent, by comparing or measuring the color depth of the solution to determine the content of the component under test, the detection limit is 0.25mg/kg.

Q:Can graphite crucibles be used for laboratory analysis?: Yes, graphite crucibles can be used for laboratory analysis. They are commonly used in high-temperature applications such as melting and analyzing various materials, including metals, alloys, and minerals. Graphite crucibles offer excellent thermal stability, high resistance to chemical corrosion, and good heat transfer properties, making them suitable for laboratory analysis purposes.

Q:Can a graphite crucible be used for aluminum casting?: Yes, a graphite crucible can be used for aluminum casting. Graphite crucibles are commonly used in foundries and metal casting operations due to their high melting point, excellent thermal conductivity, and resistance to chemical reactions. Aluminum has a relatively low melting point (around 660°C or 1220°F), making it suitable for graphite crucibles, which can withstand temperatures up to 3000°C (5432°F). The graphite crucible also helps in facilitating the transfer of heat from the heat source to the aluminum, ensuring proper melting and casting of the metal. However, it is important to note that graphite crucibles may undergo wear and tear over time due to the corrosive nature of aluminum, so regular inspection and replacement may be necessary to maintain casting quality.

Q:Graphite crucible heat resistance, then graphite crucible can ignite? Charcoal is mainly composed of graphite, why charcoal can be ignited?: Is not the same as the graphite crystal transition in carbon charcoal, but amorphous carbon, no C-C covalent bond. Charcoal ignition point is 320-370 DEG C, the general fire than the high temperature, so the charcoal can be ignited.

Q:In the melting of aluminum alloys, what is the frequency furnace and the crucible type furnace? I heard that the frequency furnace power is lower, faster and more power saving: Medium frequency electric furnace will save a lot of electricity. Medium frequency electric furnace is also placed inside the graphite crucible, copper melting.The last time I saw a foundry over there in Anhui, where the crucible was used to smelt copper, the three or four furnace had to be replaced with a crucible.

Q:Can a graphite crucible be used for gold or silver melting?: Certainly! A graphite crucible is capable of being used for the melting of gold or silver. The thermal conductivity of graphite crucibles is remarkably high, enabling the efficient transfer of heat during the melting process. Moreover, graphite possesses a high melting point and exhibits resistance to chemical substances, rendering it suitable for enduring the elevated temperatures and corrosive conditions that arise in gold and silver melting. Graphite crucibles find widespread utilization in diverse industrial sectors such as metallurgy, jewelry production, and dental laboratories. These crucibles are employed for the purpose of melting and casting precious metals like gold and silver.

Q:Are graphite crucibles suitable for melting superalloys?: No, graphite crucibles are not suitable for melting superalloys.

Q:Is the yellow metal in the graphite rock gold?: It would be more convenient if we could find the touchstone. From the proportion can be simply measured, the proportion of gold is very large.

Q:Is it possible to cast or mold materials using a graphite crucible?: Casting or molding materials can indeed be done with the use of a graphite crucible. In numerous industries, including metal casting, jewelry making, and foundries, graphite crucibles are commonly employed due to their exceptional thermal conductivity and high melting point. Thanks to their ability to endure extreme temperatures, graphite crucibles are perfect for melting and casting materials like metals and alloys. Furthermore, these crucibles possess great chemical resistance, ensuring that the molten material remains uncontaminated. Moreover, graphite crucibles exhibit low thermal expansion and are non-wetting, meaning they do not stick to the melted material, simplifying the process of removing the solidified cast or molded material. All in all, graphite crucibles are extensively utilized and highly efficient when it comes to casting and molding a wide range of materials.
