FAQ

How long should it be to store coke in the open air

The ground is flat, so it is convenient to transport.In addition, if it can be stored indoors, try not to open. For shelter.

China's coke iron smelting began in what time?

In the early period of the Warring States period, China has mastered the technology of decarbonization and heat treatment. The late Warring States period, but also invented a reusable "Iron Fan" (made of iron casting metal utensils of the hollow device). The Western Han Dynasty, appeared the crucible process. At the same time, the further expansion of the scale of shaft furnace. In 1975, in the vicinity of Zhengzhou guxing town discovered and unearthed Han iron smelting sites, site area of 120 thousand m2, two parallel excavated foundation of blast furnace, blast furnace volume of about 50m3

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

Improving the coal preparation process is the way to expand the coking coal source and improve the quality of coke. At present, most of the coking plants in China adopt the mixed grinding process. This process can not be treated according to the different hardness of coal, so it is only suitable for the coking coal with good caking property and uniform coal quality. A new coal preparation process has three kinds: single comminution process is various, coal crushing alone first, and then according to the provisions of the proportion, then mixing; the first group grinding process, hardness of similar kinds of coal, according to the proportion of each group, were sent to the respective crushing requirements the particle size, then mixing the crushing process; is crushed to a certain degree of coal sieving, the coarse grain group screened were crushed again, so that the coarse grain group cohesiveness, inert material with high content of ground fine, avoid good bonding facies excessive grinding components.

The total amount of heat released by the fully burnt 200g coke is 60% by mass of 10kg water absorption [q coke =3.0 * 107J/kg, C water =4.2 * 103J/ (kg = C)], q:(1) how much heat is absorbed by water?(2) if the initial temperature of water is 10 degrees C, then, after absorbing heat, the temperature will rise to how much?

Dry water temperatures:Delta t=Q ceilingC water m water=3.6 x 106J4.2 x 103J/ (kg * c) * 10kgC = 85.7,At the end of a water temperature t=t0+ t=20 C +85.7 =105.7 oc,

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)

What is the amount of waste gas produced by a ton of coke burning

Metallurgical coke with high carbon content, high porosity, high strength (especially high temperature strength), is an important fuel and reducing agent of blast furnace ironmaking, but also the entire blast furnace pillar supporting agent and loose agent

What does Coke test index M25 mean?

Coke is the solid product of high temperature carbonization, the main component of which is carbon, which is a kind of crack and irregular pore structure. 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)

Purpose of using coke in iron making raw materials

The coke can provide the heat required for the reaction and has the reducibility
