1. Structure of Metallurgical Coke of Met coke of CRI 26 Description：

China's coke products in the international market occupies an important position, has become the world's biggest exporter of coke coke exports about 14 million tons per year, accounts for nearly 60% of the international coking coal trade, only in the coke in Shanxi Province is more than 50% of the total international trade in the market.

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

5. FAQ

Tianjin port is China's largest coke export port, its price has become an indicator of international coking coal market.

Q:Can the sulfur content of coke affect the casting process of nodular cast iron at 0.65?: The high sulfur content of nodular cast iron, the most significant impact on the casting is caused by poor balling,

Q:What is coke? What is the use?: In addition to coke for iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, its quality requirements vary. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength. But requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.

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:Various types of coal coke are the main test items: The basic instrument of coal laboratory of these conventional indicators required are: calorimetry, sulfur detection apparatus, muffle furnace (Gao Wenlu), or when the microcomputer controller temperature controller, drying oven (oven), instrument, glial layer measuring instrument, the ash melting point determination of caking index, in addition to auxiliary equipment: crusher, pulverizer, electronic balance, vibration sieve machine, two points etc.. The above is the coal test indicators by Hebi Huanuo coal testing equipment factory to provide, I hope to help you.

Q:How much coke can a ton of coal: The key depends on volatile coking coal quality good volatile low words should now 1.3-1.4 tons of coking coal out of a ton of coke

Q:How much coal can a kilogram of coal weigh?: The ratio is about 1 to about 0.7, that is, about 1 kilograms of coking coal can produce a total of about 0.7 kg of coke

Q:The chemical composition of coke is m10.m25: Quality index of cokeThe quality index of coke coke [] is a solid product of high temperature carbonization, the main ingredient is carbon, is the pore structure has a crack and irregular (or pore porous). The crack number directly affects the coke strength and crushing strength, the index of general degree (refer to how to crack crack length unit the volume of coke in the measure.) to measure the pore structure of the main indicators for the porosity (coke pore volume only percentage of the total volume) that it affects the coke reactivity and strength

Q:Listen to a lot of people say that steel is now coke is not true?: Steelmaking is definitely not coke, but now most of the very mature iron making technology needs coke, the future direction of development of iron is not used or less coke

Q: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

Q: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)
