Product Description

A crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot.

Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and etc.

Q:Will long-term use of carbon alloy chopsticks cause cancer?
The chopsticks are washed with water for a long time, and the water content is especially high. The chopsticks are placed in the non ventilated place for a long time, and the chances of deterioration of the chopsticks are improved." Huang Yahui said, especially the moldy chopsticks, may be contaminated by aflatoxin. It is understood that aflatoxin is the 1 class of carcinogens, is a highly toxic highly toxic substances, human and animal liver tissue will have a damaging effect, can lead to serious liver cancer or even death. Huang Yahui warned that the public should be weekly chopsticks into boiling water after half an hour, placed in the air to air dry before use, it can achieve the disinfection effect, and can effectively and conveniently remove mildew in chopsticks. In addition, it is best to use half a year to replace the new chopsticks, so you don't have to worry too much. "The selection of chopsticks is also very exquisite."." Huang Yahui said, "the ideal chopsticks are bamboo chopsticks and non staining wooden chopsticks.". After the dyed or painted wood, paint and stain will enter the body with food. When in use, especially the stain in heavy metals, benzene and other harmful substances, can cause gastrointestinal inflammation, ulceration, erosion, serious can cause cancer.
Q:Can carbon in barbecue cause cancer? Can carbonated food cause cancer?
At the same time, there is another carcinogen in the barbecue food - nitrosamines.Why not eat barbecue food, mainly because of its high fat content, not health, but also not easy to digest, in addition, because the stall in the barbecue grill to add spices and other things, therefore, the body fat intake will cause degeneration in vivo, which leads to the occurrence of cancer.
Q:Consult the carbon content of austenite
Pure iron carbon alloys, austenitic (A) carbon content in different grades, different temperature and different, in more than 727 degrees (727 degrees when the carbon content is 0.77%), 1148 degrees, 2.11% carbon content with see iron carbon phase diagram
Q:What is the difference in carbon content of low carbon steel, medium carbon steel and high carbon steel?
The carbon content of medium carbon steel (AISI1029 to 1053) is 0.25% to 0.55%, manganese content is 0.30% to 1%, phosphorus content is not more than 0.04%, sulfur content is not more than 0.05%.
Q:What does "carbon neutrality" mean?
Carbon neutral (Carbon, Neutral)The new Oxford English dictionary published in 2006 annual vocabulary "Carbon Neutral", Chinese translated as "carbon neutral", global warming and carbon dioxide emissions are closely related, "carbon neutral" refers to the total emissions of carbon dioxide is calculated, and then put these emissions by planting digest compensation, do not give the earth additional greenhouse gas emissions (mainly including carbon dioxide, methane etc.) burden, achieve the purpose of environmental protection.
Q:Why carbon fiber resistant to low temperature
Resistance to 180 DEG C carbon fiber can be low temperature, under this condition, many materials are brittle, even sturdy steel has become fragile than glass, and carbon fiber under this condition is still very soft.
Q:What is electrical carbon?
Different uses have different varieties, according to the use of electric carbon varieties can be divided into:(1) sliding contact carbon brushes and carbon sliders for all kinds of motor brushes.(2) various carbon and graphite contacts used in high power switches, relays, etc..(3) with various carbon arc lighting, carbon arc gouging, spectral analysis and arc furnace.(4) all kinds of high purity graphite electrodes, insulation and supporting elements for electric vacuum devices.(5) various electrodes used in dry cells and electrolytic cells.(6) the resistance effect of carbon. Made of various resistance, post, communication with the microphone carbon sand, resistance heating elements etc..
Q:Process for producing carbon fiber board
Method for making carbon fiber sheet:1, first determine the thickness of the plate to be made2 calculate the required number of plies according to the thickness3, and then according to 0 degrees, 45 degrees, 90 degrees, -45 degrees in the order of stacking.4, and then molding it!Now carbon fiber board, in fact, many in the middle are entrained with some glass fiber cloth, of course, there are all carbon, a little more expensive!
Q:DNF advanced furnace carbon success rate
Specifically, for a random item / skill, there is an initial probability, called C. (for each item / skills are different) for example, roaming learned a 10 crit, so he first attack crit rate is C, if not crit, then the next attack, the system will take the chance to crit increased to 2C, if not a crit, then to improve to 3C... Until a crit, and start all over. The next chance of crit returns to the very beginning of C. (obviously, if has not crit, so after a certain number of attacks on X X*C>1, then this will surely be a crit) this is our game in random, many people may have noticed that some of our props inside the game, such as Tara jewelry sets BUFF probability is 1%, but in fact the BUFF probability is much more than 1%. Many props are like this, such as the title of death, robot necklace...... The odds of a low probability are high. The reason is that everything in the game is pseudo random, and our random values are always superimposed, that is to say, definitely. Strengthening equipment is the reverse, for the first time is 100%, and then multiplied by a C, has been multiplied to the probability of infinity approaching 0...... So the cushion works in theory. Believe to see, understand the players have already understood, want to play high carbon to the biggest use, depend on mat. After understanding this point of view we can count the cost of the 20 high carbon equipment 8 yuan then taking yxb:rmb1:20 as an example, if more than 160W will use cost-effective equipment than carbon somehow expensive ~ here is to provide you a way
Q:There are several allotropes of carbon
Allotrope of carbon: diamond, graphite, carbon 60 (fullerene), amorphous carbon (charcoal, coke, activated carbon, etc.)
