1. Structure of Metallurgical Coke of Coke Strength after Reactivity 64 Description

Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.

Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame.

Blast furnace with Coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.

5. FAQ

We have organized several common questions for our clients,may help you sincerely:

1) How to guarantee the quality of the products

We have established the international advanced quality management system,every link from raw material to final product we have strict quality test;We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

2) What are coke's main physical properties?

The average heat capacity is 0.808 kj/(KGK) (100 ℃), 1.465 kj/(KGK) (1000 ℃)

Thermal conductivity is 2.64 kj/(MHK) (room temperature), 6.91 kj/(MHK) (900 ℃);

Ignition temperature (air) is 450-650 ℃.

3) How about your company

Our company began to export coke when China cancelled 40% of coke export tariffs and quotas on January 1, 2013. We export many kinds of coke, such as CSR60 % and CSR 62% metallurgical coke (met coke), the NUT coke of 20 to 50 mm, coke breeze of 3 to 6 mm, and so on.

Q:Why does casting coke require phosphorus?
Foundry coke is used in cupola melting iron will fuel. Because the blast furnace cupola and metallurgical industry is different, only melting effect, without reduction reaction, the furnace is not so dephosphorization, the phosphorus in coke, some will come back to this in the metallurgical molten iron, called "Rephosphorized", this is decided by the principle of thermodynamics and kinetics. To make the original low phosphorus iron phosphorus increased harmful phosphorus. Therefore, the general foundry to buy Coke require low phosphorus coke. Some foundry with part of lime and dolomite in dephosphorization of iron in cupola, in the process, can relax the requirements for coke. However, this is suitable for large-scale, continuous production of iron.
Q:Various types of coal coke are the main test items
The basic instrument of coal laboratory of these conventional indicators required are: calorimetry, sulfur detection apparatus, muffle furnace (Gao Wenlu), or when the microcomputer controller temperature controller, drying oven (oven), instrument, glial layer measuring instrument, the ash melting point determination of caking index, in addition to auxiliary equipment: crusher, pulverizer, electronic balance, vibration sieve machine, two points etc.. The above is the coal test indicators by Hebi Huanuo coal testing equipment factory to provide, I hope to help you.
Q:The total amount of heat released by the fully burnt 200g coke is 60% by the mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)
Dry water temperatures:Delta t=Q ceilingC water m water=3.6 x 106J4.2 x 103J/ (kg * c) * 10kgC = 85.7,At the end of a water temperature t=t0+ t=20 C +85.7 =105.7 oc,
Q:Braised meat burning coke, iron black layer, I do not know how to clean, please help answer
If the paste pot may wish to try the following several waysBrush pot1, with hot water can be, it is easy to wash, do not use wire brush the ball, put the pot brush bad, if it is aluminum brush used for cooking after eating on the body is very good. (if you must brush it, you can use the cloth to replace the steel ball)
Q:Is the power plant using coking coal or coke?
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:What kind of coke is needed for smelting special steel
It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace in a certain proportion, batch and sequence, and then to produce molten iron in the reducing atmosphere of the blast furnace
Q:What is coke? What is the use?
In addition to coke for iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, its quality requirements vary. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength. But requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.
Q:Dry or dry carbon carbon, coke or coke, and I do not know which word of
Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
Q:What are the companies that produce coke
Too many enterprises to produce coke. You search on Baidu, coke, a lot of business
Q:What's the connection between coking coal and coke
Coke: the quality is hard and the hole is thick, the short hair will be wiped awayCoking coal is a kind of bituminous coal with medium caking property and strong caking property. The title of bituminous coal with high degree of coalification. Main coking coal.
