1. Structure of Metallurgical Coke of Nut coke of 20-40mm 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.
Inventory status is an important index of supply and demand analysis.Production, trade, consumers are mainly based on the change of coke prices and its own inventory ability to adjust the inventory.Inventory is to analyze the important index of coke price trends.Such as: total coke export 75% of tianjin port, has become China's coke export prices.Inventory, inventory and the inventory report report.Report inventory is also called the "dominant" inventory, inventory refers to the exchange.

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.
- Q: Coke is divided into several kinds of specifications ah
- Three: 1 2 3 coke metallurgical coke of high sulfur cokeCoke is in coal under the condition of air isolation, heating to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage is made, the process is called high temperature coking (high temperature carbonization). Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis. 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.
- Q: What is the difference between coking coal and coke
- Therefore, coke is not coking coal, coking coal is one of the products after processing
- Q: What kind of coke is needed for smelting special steel
- The role of coke in blast furnace ironmaking can be summarized as follows: 1:(1) provide the heat: coke in the coke oven in front of the raceway in the intense combustion, combustion heat generated in the blast furnace smelting process is the main heat source(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.
- Q: How much coke can a ton of coal
- The ratio is about 1 to 0.7, that is to say, 1 kilograms of about 0.7 kg coke coking coal coke, coke did not reach 0.75 kg, 0.71.Don't listen to them char 1.4:1, personal feeling.
- Q: What is the amount of waste gas produced by a ton of coke burning
- Process for producing coke, coke oven gas and coking chemical products by thermal decomposition and coking.
- Q: What is the phosphorus content in coke
- Generally, the phosphorus content of coke is low, about 0.02%.The bituminous coal is heated to 950-1050 DEG C under the condition of air isolation
- Q: What is the difference between coke and carbon residue? Coke is a high-temperature refining, carbon residue can be used for civilian fuel it?
- 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: What are the requirements for the quality of coke in blast furnace smelting
- Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand in about 30%.Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10 value method, commonly used in our country the German migon drum test.
- Q: Natural gas can replace coke smelting pig iron
- No, because the coke in the blast furnace to heat, reducing agent, skeleton and carbon supply four functions
- Q: What's the difference between coke and coke?
- When the dry distillation is carried out in the chamber type dry distillation furnace, the primary thermal decomposition product is contacted with the red hot coke and the high temperature furnace wall, and the two thermal decomposition occurs, and the thermal decomposition product (coke oven gas and other coking chemical products) is formed in the two timeThe solid product of low temperature distillation is a black semi coke with loose structure, low gas yield and high tar yield;The high temperature distillation solid product is the structure compact silver gray coke, the coal gas production rate is high and the tar production rate is low
