1. Structure of Nut    Coke    with     Low     Phosphorous 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:Effect of coke powder ratio on the index
6, the size of coke in the blast furnace, coke screening is very important. We used the coke size requirements: large oven coke particle size greater than 40mm (1300--2000 square meters); small blast furnace coke particle size greater than 25 mm. But experiments show that some steel mills, coke size 40--25 mm good. More than 80mm of coke are screened to little change in the size range. This fragmentation of the coke uniform gap, small resistance furnace is running well.Purpose: various specifications of Shanxi foundry coke, metallurgical coke, coke car or high sulfur transport cars online sales. The specific indicators are as follows:Fixed carbon 83 or above; sulfur less than 0.5; 1.5 or less volatile; ash about E:Focal mechanism:Violin coke size 8 cm -150 cm:Metabituminous:Bulk modified coke:Size of 25 cm:
Q:Effect of coal fineness on coke
The fineness of pulverized coal, which is less than 3mm of grain size, has a great influence on the quality of coke. The fineness of coal is one of the indexes of coal blending quality. In the production, when determining the fineness of coal, we should consider two aspects of the quality uniformity and production operation.
Q:What is the difference between coke and carbon residue
Coke concept:Bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage of this process is made of coke, coking high temperature (high temperature carbonization). By high temperature coking coke for blast furnace smelting, casting and gas generated in the process of coking. After the recovery and after the purification of coke oven gas is not only a high calorific value of fuel, and is an important raw material for organic synthesis industry. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% were used for blast furnace ironmaking blast furnace coke, so often referred to as metallurgical coke is coke. The special cupola molten iron and coke. Coke is the main fuel cupola molten iron. It is melting charge and molten steel overheating, the support column to maintain its good permeability. Therefore, coke should Have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
Q:Types of coke and use of coke
Generally speaking, the use of coke in the following industries: blast furnace ironmaking, mechanical casting, calcium carbide production, processing Ferroalloy, chemical fertilizer, gas and high-tech high value-added industries
Q:Who can talk about the coke industry prospects?
But at present, the iron making technology without coke has not yet been relatively mature, and it is not dominant compared with the traditional ironmaking technology. Coke industry still has development prospects.
Q:Coking tower and coke tower is what relationship?
The question is not clear, according to the words you say should be: coking tower = coke towerThat will not help you
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:What is the essential difference between coal and coke?
[coal]Coal is a kind of solid combustible mineral which is buried in the underground plants and has been formed by the complex biochemical and physicochemical changes. Coal is a kind of solid combustible organic rock, which is mainly formed by the chemical reaction of the remains of plants.
Q:Coke boiler belongs to coal-fired boiler
Coke is commonly used in the smelting industry, such as iron smelting converter, steel blast furnace, ferroalloy electric furnace, etc.
Q:How easy to use coke barbecue?
Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage.
