Introduction 

1. Graphite crucible can be used for non-ferrous metal smelting and casting, dissolving gold

or silver ornaments, analysis of special type steel, sintering hard metal.


2. graphite crucible for smelting gold is specialized in melting gold in headgear and jewelryindustry. That requests graphite material has high density and purity, ablation-resistance, and it can be used many times. We can machine various crucibles accordingto customer's requirement.


3. Machined from high pure graphite and widely used in the gold,silver,platinum and other noble metal's melting.If it's used in oxygen atmosphere,it wil start to be oxygenized when the temperature is higher than 700-800°c. If it's used in the protective atmosphere, it can stand more than 2000°c.


4. widely used in such fields as industrial furnaces, mono-crystalline silicon machinery, mono-crystalline silicon machinery, electron, semi-conductor, metallurgy, oil, chemistry, textile, electrical machinery, electrical equipment, electrical furnace, traffic, communication industry, medicine, etc.

Q:What can replace a graphite crucible?
Graphite crucible special tips:1. Be careful not to let the mechanical outside hit, do not belong or strike from the top.2. Should not be exposed to water or stored in a dry place.3. Built in melt dry, without contact with water.4. In use, flames that are not directly in the crucible (jet to the bottom of the crucible) will have a marked black mark at the bottom of the crucible if it is sprayed.5. After the aluminum is stopped, the remaining copper material is tried without leaving residue in the crucible.6. Use the proper amount of oxide (slag, etc) to avoid erosion of the crucible. Excessive use may cause erosion and damage to the crucible.7. When placed in a crucible, there is no need to use mechanical power to have a significant impact.
Q:What's the difference between crucible furnace and non crucible furnace in die casting industry?
The stove is not without crucible furnace crucible said above, the molten pool is built by the whole plate, high aluminum refractory castable, heating with resistance wire, silicon carbide, top mounted combustion heating machine, dipping type silicon carbide rod. The furnace has a life expectancy of about 3 or 5 years.
Q:How long will it take to warm the water at 20 degrees to 3000 degrees at 3800?
The temperature of the heater can not be reached 3800C unless heated by high-energy laser, high-energy electron beam, plasma, etc.. However, the heating area can reach the high temperature equipment can be achieved is very small, but also have the conditions of use, such as electron beam high vacuum environment (water can not reach the requirement of high vacuum), laser heated material can absorb light energy (water absorption), the velocity of gas plasma is very high, very fast cooling the total energy is very small.
Q:Graphite used in graphite in the glass industry?
Graphite used in the glass industry, some graphite crucible furnace, because graphite temperature resistance is good, but the graphite products must be anti oxidation treatment.
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:How to select and use the carbon graphite for machinery? What items should we pay attention to?
Selection must be based on the working conditions of the equipment, taking into account the pressure, wire speed, medium, and grinding materials and other factors, if necessary, after the test selected appropriate.
Q:Who knows the method for determining the total iron content in iron ore?
Iron is one of the most widely distributed metal elements in the earth, with an average content of 5% in the earth's crust and fourth after oxygen, silicon and aluminum in the element abundances. Iron minerals in nature are known to have 300 kinds, but in the current technical conditions, with industrial utilization value is mainly magnetite (iron containing 72.4% Fe3O4 (Fe2O3), hematite iron containing 70% (FeCO3) and siderite iron containing 48.2% (Fe2O3 / nH2O), limonite iron containing 48% ~ 62.9%).
Q:What is the main function of graphite?
Graphite has good chemical stability. After special processing of graphite, with corrosion resistance, good thermal conductivity, low permeability, is widely used in the manufacturing of the heat exchanger, the reaction tank, condenser, combustion tower, absorption tower, cooler, heater, filter and pump equipment. Widely used in petroleum, chemical, hydrometallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, can save a lot of metal materials.
Q:Aluminum graphite crucible for iron crucible which is good
The graphite crucible produced by our factory can live for 6-9 months.
Q:How to extract gold from activated carbon filter?
Depends on the gold in your filter is what state, the ionic state can be used acid and other analytical solution, and then reducing agent or thiourea reduction of gold, simple gold can be replaced by Wang Shuirong, but the impurities will be more.
