Many manufacturers will be a little fuzzy carburizer types when purchasing, so today we graphitized petroleum coke manufacturers to take a look at the difference between calcined petroleum coke carburizer and graphitized carburizer.
Raw materials: raw petroleum coke is used.
Two: fixed carbon content.
The main results are as follows: (1) the carbon fixed by graphitized carburizer is generally about 98%, up to 99%.
(2) after calcination, the fixed carbon of petroleum coke carburizer is about 98.5%.
III. Smelting environment.
The main results are as follows: (1) graphitized carburizer is produced at about 3000 ℃ in graphitization smelting furnace.
(2) the carbonization agent for calcined petroleum coke is produced at the temperature of more than 1500 ℃ in the forged smelting furnace.
4. Smelting time: the smelting environment of graphitized carburizer is longer than that of calcined petroleum coke carburizer.
Five: the content of sulfur.
The main results are as follows: (1) the sulfur content of graphitized carburizer is generally between 0.03 and 0.06%, which is more than 0.05%.
The absorption rate is generally between 90% and 95%.
(2) the sulfur content of carbonization agent for calcined petroleum coke is generally about 0.5%.
The absorptivity is generally between 80% and 90%.
The two carburizing agents are used in the same way, and there will be differences in the amount used according to the different manufacturers. Although the price of graphitized carburizing agent is higher than that of calcined petroleum coke carburizing agent, but in terms of overall use cost,
The selection of graphitized carburizer is still the most economical, therefore, in the past one or two years, many foundry steelmaking manufacturers also gradually began to tend to the purchase of graphitized carburizer.
It cannot be ruled out that the current low oil prices will remain low for quite some time.
To understand the current situation, we need to look back at history and look at the similarities and differences between the two stages from 1979 to 1987 and 2007 to 2015.
The similarity is that in both stages, oil prices fell by more than 70%, with an increase in supply from non-OPEC countries: the rise of North Sea oil in the 1980s and the vigorous development of shale oil in the United States today;
In both stages, Saudi Arabia unilaterally announced that it would not cut production and sell oil at low prices.
In the previous stage, changes in the market structure led to 14 years of relatively low prices until 2000.
It is worth noting that at the end of 1979, oil prices were approximately $30-40 per barrel.
Oil prices fell to $5 a barrel in 1986 and eventually reached a balanced price of $15 to $20 a barrel, which lasted until 2000.
If it continues to follow the same pattern as last time, oil prices will remain low until 2030.
The difference between the current stage and 1986 lies in the difference in surplus production capacity: in 1986, OPEC had a surplus production capacity of nearly 10 million barrels per day, whereas today, this production capacity is about 2 million barrels per day.
So low oil prices will last for a while, but not for more than a decade.
