Q:What is the difference between coke and semi coke in ferrosilicon smelting process? In the process of energy statistics in the end should be 0.9714 of the conversion coefficient should be used with the conversion coefficient of 0.75 x 0.9714, please expert advice? emergencyUrgent!

Coke is used for smelting iron alloy coke, and the coke is used in blast furnace and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, heating agent and columnar skeleton.

Q:How much coke is needed for a ton of iron

1 tons of iron: iron ore + + coke 340kg + pulverized coal injection 130kg,The process of extracting iron from iron containing minerals, mainly iron oxides, is mainly composed of blast furnace, direct reduction, smelting reduction and plasma method. From the perspective of ironmaking is metallurgy, iron rust, inverse behavior gradually mineralized, simple, pure iron reduction from iron compounds. Pure iron is not common in actual production. More iron carbon alloy.

Q:What are the requirements for the quality of coke in blast furnace smelting

Evaluation of coke quality1, sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. The sulfur content in the pig iron is more than 0.07%. 11% of the sulfur from the blast furnace charge into the furnace comes from the ore, and the other comes from the limestone; the other is from the coke, so the coke is the main source of sulfur in the charge of the 82.5% of the charge. Sulfur content in coke directly affects the production of blast furnace. When the sulfur content in coke is greater than 1.6%, sulfur increased 0.1%, the amount of coke increased 1.8%, limestone amount increased 3.7%, 0.3% increase in amount of ore blast furnace output to reduce the sulfur content under 1.5 - 2.0%. metallurgical coke is not greater than 1%, the use of large and medium-sized metallurgical coke content in blast furnace is less than 0.4 - 0.7%.2, the phosphorus in the coke: iron metallurgical coke coke content should be in the following 0.02 - 0.03%.3, the ash content of coke: Coke Ash on the impact of the blast furnace smelting is very significant. Coke ash increased by 1%, coke consumption increased by 2 - 2.5%, therefore, the reduction of coke ash is very necessary.

Q:What is the reasonable ratio of coal to coke

Coal is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, and carbon, hydrogen, oxygen and three of the total possession of more than 95% of the quality of the machine, is a very important energy, metallurgy, chemical industry is an important raw material

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?

Gasification coke, which is used in the production of coal gas, is mainly used in the fixed bed gas producer with solid slag, as the raw material for gasification, producing CO and H2 as the combustible component:C+O2 - CO2+408177KJCO2+C - 2CO-162142KJC+H2O - CO+H2-118628KJC+2H2O - CO2+2H2-75115KJ

Q:What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you

Q: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;

Q:The difference between coke and coal

Coal is known as the black gold, the food industry, which is one of the main sources of energy used in the human world since eighteenth Century...

Q:Coke is how to make it? What is the use?

The production process has the following procedures:The preparation of coking coal is called coal preparation, which is prepared from various kinds of cleaned coal (or raw coal with low ash content), which is made up of coal, which has the advantages of high accuracy, good particle size, uniform quality and meeting the requirements of coking. Generally include: coal unloading, storage and mixing, mixing, crushing and mixing, and the preparation of coal to coke oven coal storage tower. In cold regions, there should be thawing and freezing equipment. To improve the quality of coke, we must pay enough attention to coal preparation. The coal blending is good, the accuracy of coal blending is improved, the fluctuation of coal quality is minimal, and the chemical composition and the physical mechanical property of the coke are ensured to stabilize the coke quality. Therefore, the coal blending equipment must be accurately according to the given value of coal blending; coal blending tank to be uniform continuous coal. In addition to the impurities in the coal, water can not be too high. The reasonable crushing of coal can effectively improve the mechanical strength of coke. According to the specific situation, the most suitable grinding particle size should be determined.

Q:What are the national standards for grade two coke?

Volatile content is not greater than 1.80; crushing strength: M40:76.1 - 80, M25:88.1 - 92; wear resistance: M10: not more than 8.5;
