Product Description:


1. Structure of Metallurgical Coke of Nut coke of  phosphorus 0.045 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.

Sulfur content in coke: sulfur is one of the harmful impurities of iron smelting, it lower the quality of cast iron.The sulfur content in pig iron for steel making is more than 0.07% for the trash.By the blast furnace burden into furnace sulfur 11% came from the ore;3.5% from limestone;82.5% from coke, so coke is the main source of sulfur in charge.Coke sulfur content directly affect the blast furnace ironmaking production.When coke sulfur content is greater than 1.6%, sulfur, every 0.1% increase in coke consumption increased by 1.8%, increased by 3.7%, for the amount of limestone ore content of 0.3% by 1.5 - a 0.3% increase in the blast furnace production. The sulfur content of metallurgical coke is not greater than 1%, large and medium blast furnace using the sulphur content in metallurgical coke is less than 0.4-0.7%.

5. FAQ

Coke ash content: coke ash content on the influence of blast furnace smelting is very significant.Coke ash content increased by 1%, the coke rate increase 2-2.5%, therefore, lower coke ash content is very necessary.

Q:The difference between semi coke and coke
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:With the number of 1 tons of steel smelting coke
Landlord is a layman. First of all, correct your mistake, steel is not used coke, coke is used to iron. You can change the question, how much Coke refining 1 tons of iron
Q:What is the reasonable ratio of coal to coke
According to the proportion of each unit type, different operation, different existing coal and different coke quality requirements are different and so on, can be said to suggest that the landlord can look at the altar of the myriads of changes, in some aspects of the coal blending, grasp some general principles, and then develop the proportion according to the actual situation.
Q:What are the criteria for coke classification and how to distinguish between primary and two grade coke?
Evaluation of coke quality1, sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. In the steel-making pig iron sulfur content greater than 0.07% is waste. By blast furnace furnace into sulfur from 11% ore; 3.5% from limestone; 82.5% from coke, so coke is the main source of sulfur in charge coke. Sulfur directly affects the production of blast furnace coke. When the sulfur content 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 sulfur content of large and medium-sized metallurgical coke the blast furnace is less than 0.4 - 0.7%.2, the phosphorus in the coke: iron metallurgical coke coke content should be in the 0.02 - 0.03% or less

Q:What is the difference between coking plant and coke plant
Production equipment and production processes are complex.Coke plant, generally only the coal into coke on it, so simple.
Q:Coke indicators are divided into grades
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:Why is coke used in blast furnace steelmaking?
The reason of coke used in blast furnace steelmaking:Coke is the product after the desulfurization of coal, because the removal of sulfur in coal, coal tar and other harmful substances, no longer in the process of steelmaking, the impact on the quality of steel, the formation of unnecessary ingredients.
Q:How much coke can a ton of coal
The key depends on volatile coking coal quality good volatile low words should now 1.3-1.4 tons of coking coal out of a ton of coke
Q:How to remove the bottom of coke steel
Two, with cooking shovel (Mason's Pihui knife is best) to remove surface soft.Three, the same with a spade close to the bottom of the pot to eradicate. Until the last thing left is black.Four, wash the metal wire ball friction force discoloration, and always use water to clean out the dirt.
