petcoke and graphite carbon-adders after radon?

Many manufacturers in the procurement will be a bit vague carbon booster types, so today we look at the difference between petcoke adders and graphite carbon adders.

First Raw materials: are made of raw petcoke.
Second: fixed carbon content
(1) Graphite carbon adder fixed carbon is generally about 98%, up to 99%.
(2) After the calcium petcoke carbon-adder fixed carbon is generally about 98.5%.
Third: smelting environment
(1) Graphite carbon adders are produced at a temperature of about 3000 degrees C in a graphite smelter.
(2) After-the-day petcoke adder is produced at a temperature of more than 1500 degrees C after forging furnace.
Fourth: Smelting time: Graphite carbon-adder smelting environment than after the otar carbon-adder smelting time is long.
Fifth: Sulfur content (1) The sulfur content of graphite carbon booster is generally between 0.03-0.06%, generally 0.05% more.
Absorption rates are generally between 90% and 95%. (2) The sulfur content of the petcoke increaser after radon is generally more than 0.5%.
Absorption rates are generally between 80% and 90%.
Sixth: Use: The use of carbon izers is similar, according to the different amounts of use of manufacturers will also have differences, although graphite carbon booster price is relatively high than the price of petroleum coke adders after calcination, but from the overall cost of use, graphite carbon booster selection is the most economical, therefore, In the past year or two, many foundry steel manufacturers have also gradually begun to favor the purchase of graphite carbon boosters.

High carbon silicon production process In the process of smelting metal silicon, there is a case where the electrodes are not uniformly heated in the furnace. As a result, the furnace bottom fails to reach the optimum temperature required to produce metal silicon. A small amount of raw materials such as silica and carbon at the bottom did not fully react. After a long period of accumulation under high temperature conditions, it forms a block on the bottom of the furnace. These large (stable traits) chunks are broken and screened, which is what we often call   high carbon silicon . High carbon silicon characteristics and uses Current market Alloys for converters have not been adjusted for a long time. The structure of traditional alloys is relatively simple. Q195 and Q235 steels adopt Mnsi+FeSi+SiAiCaBa+Sic+recarboration process. HRB335 and HRB400 steel grades adopt MnSi+Fesi+AiSi+ recarburizer production process. The traditional silicon-manganese alloy, the m...

Henan star metallurgy (located in anyang city) specializing in silicon metal powder 441, silicon metal powder 553, silicon metal powder 3303 research and production sales, silicon metal price how much money a ton?The company will offer the price according to the content and granularity required by customers at any time. Introduction to silicon metal powder : Silicon metal powder is silicon metal (industrial silicon) after grinding and processing of silicon powder. Metallic silicon, also known as crystalline silicon or industrial silicon, is primarily used as an additive to non-ferrous alloys.Industrial silicones are also used as alloys for demanding silicon steels, deoxidizers for special steels and non-ferrous alloys.After a series of processing processes, industrial silicon can be pulled into a single crystal silicon for use in the electronics industry. Silicon metal property ,Metallic silicon is composed mainly of silicon, so it has similar properties with sil...
