Q:How coal is turned into coke in the coking chamber

In the furnace in the absence of air through the kiln wall edge ignition hole artificial ignition, coking coal will be stacked in the kiln fire, coking coal self combustion heat by layer coal heating (direct fire heating); a large amount of coal gas from coal combustion and unburned cracking formation hot air flow,

Q:What is cokeWhat applications are, what is the fire of Malachite copper

Coke is a kind of reducing agent (C), under the heating conditions and some of the oxidation reduction reaction, can restore some important minerals, such as steel mills, etc..

Q:I now do a good job in the coke network editor, I would like to know more about coke

Coke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on. In the process of blast furnace smelting, there are four kinds of functions, such as heat supply, reduction, material skeleton and carbon supply.

Q:Purpose of using coke in iron making raw materials

Purpose as follows:1. Provide the heat required for the reaction2, do reducing agent, generate CO, at the same time itself can also restore the iron

Q:I don't understand. With coke, then the rest of the coke, they are selling it?

If most of the solid fuel is burning coal, but coking coal, which is very strong viscosity of coal is not good, it is very interesting to use the individual plant with it, the purpose is to change the fuel characteristics.Coking coal and coke, commonly used in metallurgical industry.Coal will be heated to a process of coke, but you really want to get coke, to specialized production. Power plants do not produce coke, they only have gray coke

Q:Do not understand why some of the indicators of coke is the cause of the full analysis of phosphorus or foundry use of this time?It is best to use the foundry requirements? Thank you

Phosphorus increased the brittleness of cast iron, the use of metal damage. Therefore, the requirements of the foundry phosphorus is the lower the better. Because of the large cupola furnace in the furnace is acidic, can not effectively dephosphorization, so the foundry coke in the phosphorus requirements as low as possible, and require the supplier to provide a quality guarantee form.

Q:Coke is divided into several kinds of specifications ah

Use:Fixed carbon above 83; sulfur below 0.5; volatile below 1.5; about 15 ash coke for metallurgical e: mechanism: {; applied to steel coke particle size 8cm-150cm:{} with hot metal; for motor shell, radiator, mechanical counterweight cast char: {of} fertilizer for hot metal; coke bulk modified casting shell, radiator, electric}: {mechanical counterweight for ordinary casting furnace;} machinery parts and other parts suitable for roughly 2-3.5 tons of coke particle size for 25cm:{type common casting and casting products slightly strict; such as fire pump pipe fastener} fixed carbon above 85; volatile ash 13.5 1.5.; the following: 0.5; sulfur with coke particle size above 8cm for ordinary casting: {} 25cm {type coke particle size; for precision casting and ductile casting improved coke}:

Q:How many degrees of coke ignition temperature can ignite coke

Ignition temperature (450-650) in air;Dry ash free base low calorific value is 30-32KJ/g;The specific surface area is 0.6-0.8m2/g

Q:What is the density of coke?

Do you want to transport by rail? Ha ha, you might as well ask the freight forwarding clerk, he / she will tell you the various models of the volume and the weight can be installed, the conversion of the density of the pile is more accurate.

Q:Can the sulfur content of coke affect the casting process of nodular cast iron at 0.65?

The level of spheroidization is not enough. The final sulfur content of molten iron before the spheroidizing treatment is best at 0.03%
