FAQ

The difference between coal and coke

Today, the Customs Tariff Commission of the State Council issued the notice on the implementation of the tariff plan in 2013. Shang magnesium network noticed,. This important change, apparently stems from the WTO requires China to cancel the export of raw materials restriction policy decisions. In recent years, due to higher export tariffs, coke exports almost stagnant, but also indirectly affect the production of magnesium metal. Due to insufficient supply of coke oven gas, and the price increases, the production of primary magnesium in the main producing area of Shanxi magnesium metal has been seriously reduced. Shang magnesium network analysis, the abolition of coke and semi coke export tariffs next year, the amount of exports should be theoretically faster recovery, some of the original magnesium production capacity will be restored. However, the government may take other measures to limit coke and semi coke production, coupled with the western economic downturn, exports may be rapid growth. Therefore, the coke industry after the abolition of export tariffs on the market situation remains to be seen, the impact on the magnesium industry has yet to be further assessed.

How long should it be to store coke in the open air

The ground is flat, so it is convenient to transport.In addition, if it can be stored indoors, try not to open. For shelter.

With the number of 1 tons of steel smelting coke

The use of coke pig iron smelting blast furnace, for each different, which is each blast furnace coke ratio (the ratio of the iron smelting a ton of coke by iron determined how many meals). The country or the world, the iron and steel enterprises coke are not the same, the coke rate is as low as possible, but there are many factors which restrict the level of coke, such as advanced level equipment, raw material and fuel quality, or the operator level, advanced process and so on many factors which influence

Why is coke used in blast furnace steelmaking?Why not use coal?

(2) reduction: high temperature gas generated in coke combustion in the raceway, passed to the material in the process of heat rising, the endothermic reaction and coke formation, CO and H2, then CO and iron oxide in iron ore reduction reaction is transformed into metallic iron.(3) the role of the skeleton: the blast furnace smelting process occurs in the movement and interaction between the rising of the gas and the falling of the charge. The pellets, coke, iron ore, ore and other materials according to a certain proportion, and batch sequence into a blast furnace, blast furnace smelting in reducing atmosphere under the hot metal, after providing to the steelmaking plant of the steel-making.

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

(3) column frame.The density of coke in blast furnace burden is the smallest, and the coke volume accounts for 35% ~ ~ ~ of the total volume of blast furnace burden. Coke is relatively strong, and in the tuyere area has always been to maintain the block, so it is the skeleton of the blast furnace column, from the loose material column, to ensure that the column has a good gas permeability of the role of the furnace is an important factor.

How many degrees of coke ignition temperature can ignite coke

The average specific heat capacity is 0.808kj/ (KGK) (100 DEG C), 1.465kj/ (KGK) (1000 DEG C);The thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C);Ignition temperature (450-650) in air;

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

As everyone knows, sulfur and phosphorus is harmful substances in the metal, because the sulfur is out in coke processing, so this index is not required, but the phosphorus in this process has not been effectively removed, so this is the requirement of foundry process or smelting plant. Phosphorus can reduce the strength of the metal, will lead to the metal "cold crisp", so to control the phosphorus content of coke, to prevent phosphorus into the metal.

Coke indicators are divided into grades

Coke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke).
