Q:How to remove the bottom of coke steel

After high temperature sintering, and carbonization of things, glued to the pot, often with chemical methods.The most effective way to do this is by hand:Soak in hot water for a few hours (or a day and night).

Q:With the number of 1 tons of steel smelting coke

The use of coke pig iron smelting blast furnace, for each different, which is each blast furnace coke ratio (the ratio of the iron smelting a ton of coke by iron determined how many meals). The country or the world, the iron and steel enterprises coke are not the same, the coke rate is as low as possible, but there are many factors which restrict the level of coke, such as advanced level equipment, raw material and fuel quality, or the operator level, advanced process and so on many factors which influence

Q:What are the indicators of first grade coke and the two grade coke?

The mechanical strength of the mechanical strength of ash sulfur%% volatile(crush strength M40) (abrasion strength M10)

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 phosphorus content in coke

After drying, pyrolysis, melting, bonding, curing, shrinkage and other stages of the final coke, this process is called high temperature coking (high temperature carbonization)

Q:Which heroes know, please give the source of the data.

From the production equipment and technology of the popular view, a ton of coke oven gas produces about 400 cubic meters, of which about 200 cubic meters of coke oven returned through the pipeline used for coking heat source, the remaining more than and 200 cubic meters was emptying, "or the lantern".

Q:Coke is how to participate in the steel, and the pellets, sintering, a piece of the furnace in the furnace or in other containers

Molten iron is produced in a reducing atmosphere of the blast furnace, which is then supplied to the steelmaking plant for steelmaking.

Q:What does the M40% and M25% mean in the analysis of coke?

(2) mainly used in: Coal Science and Technology (first level), coal processing and utilization (level two), coal chemistry and coal quality analysis (level three)

Q:What are the main uses of coke

The utility model is used for casting blast furnace smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury, etc..

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
