Product Description:

1. Structure of Metallurgical Coke of Coke Strength after Reactivity 62 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.

Bituminous coal under the condition of the air, heated to 950-950 ℃, after drying, pyrolysis, molten, bonding, solidification and contraction phase resulting coke, this process is called high temperature coking (high temperature carbonization).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.

5. FAQ

Foundry coke is dedicated to cupola molten iron. Coke is the main fuel of cupola molten iron. Its role is hot metal melting furnace charge and overheating, support stock column maintain its good air permeability. As a result, coke blocks should have large, low reactivity, low porosity, with sufficient impact crushing strength, ash content and low sulfur content.

Q:In the coke analysis index, M40% and M25% respectively mean what?
(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:Effect of coke powder ratio on the index
Evaluation of coke quality1, coke: sulfur sulfur is a harmful impurity, pig iron smelting, which makes it one of the iron quality. In steel and iron sulfur content greater than 0.07%, is a waste. From the 11% blast furnace of sulfur ore; 3.5% limestone; 82.5% from coke, so coke is the main source of sulfur. The charge directly affects the coke into blast furnace of sulfur when the sulfur content of coke production. For more than 1.6%, 0.1% sulfur, each additional 1.8%, increase the amount of coke, an increase of 3.7%, ore blast volume added limestone to reduce the yield by 0.3%, sulfur content of 1.5 - 2% metallurgical coke requirements do not exceed 1% 0.7%., the sulfur content of metallurgical coke is less than - 0.4 large and medium sized blast furnace
Q:What is the difference between coke and carbon residue
Types of coke:Coke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke, calcium carbide and coke gasification etc.) with coke. The pressurized pulverized coal forming coal, coke carbonization etc. in the new postprocessing process called Formcoke.1, metallurgical coke, metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke.The metallurgical coke quality standard (GB/T1996-94) made in China is the quality standard of blast furnace
Q:Dry or dry carbon carbon, coke or coke, and I do not know which word of
Dry carbon is not coke, but the combustion will produce a lot of harmful substances, it is recommended to install a more advanced cleaning device. Thank you
Q:How much coke oven gas is produced?
You have to know what kind of coal isBituminous coal and anthracite are determined according to the content of volatile matter in coal,Bituminous coal has C content, geological time is long, but not easy to burn!It is also different from the different producing areas of bituminous coal. Mainly depends on what you want to be low calorific value (not including the vaporization of water vapor latent heat release). High calorific valueTo determine the coal species, industrial analysis, to determine the content of water, ash, volatile, fixed carbon content!That is, there is no formula, mainly the test.Low calorific value = high calorific value -206*H-23MH-- hydrogen contentM-- moisture content (both received base)
Q:The chemical composition of coke is m10.m25
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 is about 30%. The crack and porosity of coke and coking coal for the level, which has a direct relationship, such as coal based coke refining cracks, porosity, high strength, low; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is used to denote the crushing strength and abrasion resistance of the two indicators.
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:The difference between coal and coke
The production of coke products in general is mainly based on high temperature carbonization, and the carbonization temperature usually needs about 1000 degrees celsius. After years of development, the current large-scale coke furnace equipment and technology is relatively mature, have equipment to improve the yield so as to achieve large-scale production conditions, coke furnace built in recent years, each with a yield of about 500 thousand tons, the highest can be even more than 1 million tons / year, such as the recent launch of mine international coking plant two chamber coke oven 7.63 m, each with a yield of 1 million 100 thousand tons per year.
Q:Coke crushing equipment prices, manufacturers offer is how much
The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke. 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%.
Q:What is cokeWhat applications are, what is the fire of Malachite copper
Malachite is a kind of copper, copper smelting with coke burning malachite is under high temperature.
