Product Description:


1. Structure of Metallurgical Coke of Met coke of CRI 30 Description:

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%.

On China's coke production distribution, the regional distribution imbalance of coking enterprises, mainly distributed in north China, east China and northeast China.

Q:Purpose of using coke in iron making raw materials
The coke can provide the heat required for the reaction and has the reducibility
Q:Various types of coal coke are the main test items
Coal test items which specific indicators of coal test:Generally include coal test indicators include: calorific value of coal (calorific value), sulfur content (sulfur), ash, volatile, fixed carbon, char residue characteristics, total moisture, water analysis and other indicators
Q:Ca3 (PO4) 2, SiO2, coke and other raw materials for the production of silica gel (SiO2? NH2O), phosphorus, phosphoric acid and CH3OH, the comprehensive utilization of raw materials in the following process
The answer is: (I), (III);(2) under the condition of high temperature, calcium phosphate reacts with carbon and silica to produce calcium silicate, phosphorus and carbon monoxide. The reaction equation is Ca3 (PO4) 2+5C+3SiO2High temperature. 3CaSiO3+2P+5CO =, calcium silicate is silicate, so can produce cement, brick or building materials such as,
Q:The total amount of heat released by the fully burnt 200g coke is 60% by the mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)
At a standard atmospheric pressure, the boiling point is 100 DEG C, the temperature of the water rises to a temperature of 100 DEG C, and the temperature will not change,So the water temperature can be increased to 100;Answer: (1) the heat absorbed by water is 3.6 * 106J;(2) after absorbing heat, the temperature of the water will rise to about 100 degrees centigrade
Q:What are the quality indicators of coke
Coke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke). 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.
Q:How to calculate the average particle size of coke
That is, "(volume) of the table of the percentage, in addition to the corresponding boundary value", these values are added, then the countdown. For example, the boundary 0 to 1 has a value of 10%, between 1 and 2, and between 2 and 4 has a value of 40%, and between 4 and 8, then D (3,2) = / (0.1/0.5 + 0.3/1.5 + 0.4/3 + 0.2/6) = 1/ (+ + 0.2 + + + 0.13 + +) = 1/0.56 = = =
Q:Coking coal, coke, coal, steam coal what is the difference?
Coking coal is the raw material for coke
Q:How easy to use coke barbecue?
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.
Q:In the coke analysis index, M40% and M25% respectively mean what?
M40% and M25% represent the breaking strength rate, 40%>25%, which means that the M40% coke is more resistant than M25%
Q:What is the reasonable standard of volatile content of coke
The 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%.
