Q:Coking coal, coke, coal, steam coal what is the difference?

Coke is used for blast furnace ironmaking and iron ore in the steel furnace to play the role of the heating skeleton to support reducing agent

Q:What's the connection between coking coal and coke

The coke can be obtained with the advantages of large grain size, few cracks and high crushing strength, and the abrasion resistance is good. But the expansion pressure, the coke pushing difficulties must be allocated to coal, lean coal, in order to improve the operating conditions and improve the quality of coke. Coking coal can play the role of coke skeleton and relieve shrinkage stress, so as to improve the mechanical strength of coke.

Q:Coke is divided into several kinds of specifications ah

Use:Fixed carbon above 83; sulfur below 0.5; volatile below 1.5; about 15 ash coke for metallurgical e: mechanism: {; applied to steel coke particle size 8cm-150cm:{} with hot metal; for motor shell, radiator, mechanical counterweight cast char: {of} fertilizer for hot metal; coke bulk modified casting shell, radiator, electric}: {mechanical counterweight for ordinary casting furnace;} machinery parts and other parts suitable for roughly 2-3.5 tons of coke particle size for 25cm:{type common casting and casting products slightly strict; such as fire pump pipe fastener} fixed carbon above 85; volatile ash 13.5 1.5.; the following: 0.5; sulfur with coke particle size above 8cm for ordinary casting: {} 25cm {type coke particle size; for precision casting and ductile casting improved coke}:

Q:What is coke and how is coke classified?

Coke definitionBituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage of this process is made of coke, coking high temperature (high temperature carbonization). By high temperature coking coke for blast furnace smelting, casting and gas generated in the process of coking. After the recovery and after the purification of coke oven gas is not only a high calorific value of fuel, and is an important raw material for organic synthesis industry. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% were used for blast furnace ironmaking blast furnace coke, so often referred to as metallurgical coke is coke. The special cupola molten iron and coke. Coke is the main fuel cupola molten iron. It is melting charge and molten steel overheating, the support column to maintain its good permeability. Therefore, coke should have Large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.

Q:What is the reasonable standard of volatile content of coke

Generally speaking, the volatile content of coke is about 1.5 or so, but not more than 2

Q:What is the phosphorus content in coke

Generally, the phosphorus content of coke is low, about 0.02%.The bituminous coal is heated to 950-1050 DEG C under the condition of air isolation

Q:What are the companies that produce coke

Very much, what kind of coke do you want, our company would like to buy coke particles

Q:The chemical composition of coke m10.m25 refers to?

1, coal washing ((M25 drum index) metallurgical coke crushing strength is (M10 drum index) metallurgical coke wear strength is reflected

Q:Coke boiler belongs to coal-fired boiler

Coke is commonly used in the smelting industry, such as iron smelting converter, steel blast furnace, ferroalloy electric furnace, etc.

Q: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
