1. Structure of Metallurgical Coke of High Fixed Carbon Metallurgical Coke Description：
Metallurgical coke is blast furnace coke, coke, iron alloy and nonferrous metal smelting with coke.As more than 90% of the metallurgical coke for blast furnace ironmaking, so often called the blast furnace coke metallurgical coke.China's metallurgical coke quality standard (GB/T1996-94) is the quality standard of blast furnace.
Coke physical properties including coke sieve grouped into truth, coke, coke powder density depending on the relative density of density, coke, coke gas porosity, thermal conductivity for the heat capacity of coke, coke, coke, coke ignition temperature, coke thermal expansion coefficient of thermal stress, coke shrinkage rate and coke, coke resistivity permeability, etc.

5. FAQ
How about your company？
Our company began to export coke when China cancelled 40% of coke export tariffs and quotas on January 1, 2013. We export many kinds of coke, such as CSR60 % and CSR 62% metallurgical coke (met coke), the NUT coke of 20 to 50 mm, coke breeze of 3 to 6 mm, and so on.
- Q:The two day of the fire is not wang you have a good way to have any good way. Such online
- Take the gas stove ignition, and so it was burning 3, and then into the barbecue. Remember to add carbon, open the ventilation cover.
- Q:Natural gas can replace coke smelting pig iron
- No, it's not just the temperature. It takes the chemical reaction of carbon and iron oxide to produce iron.Chemical equation: C+Fe 3O4 - Fe+CO2
- Q:Why is coke used in blast furnace steelmaking?Why not use coal?
- The role of coke in blast furnace steelmaking is as follows:(1) providing heat: the coke burns fiercely in the raceway in front of the tuyere of the coke oven, and the heat generated by the combustion is the main heat source in the process of blast furnace smelting.
- Q:Who knows the proportion of pig iron and coke used in Cupola
- There is doubt: the export rate is lower than the standard exception.4, blank blank processing: according to customer requirements of different direct sales, some need to continue processing after the sale, the ordinary rough machined after a blank rate of about more than 70%, about 30% (excluding scrap scrap), dryer enterprises after after machining yield is about 25% ~ 30% (including waste scrap and iron, basically use recycled material, material waste accounted for ratio of 30% ~ 40%). To 1.5M x 2M cylinder, for example, rough weight of about 5.8 tons ~ ~ 6 tons (standard cylinder, including the cylinder head) cylinder head rough weight of about 1.7 tons ~ ~ 1.8 tons, cylinder weight of about about 4.2 tons. After processing, the cylinder head weighs about 0.5 tons to 0.6 tons, accounting for the proportion of about 65% to 70% head (excluding scrap, scrap accounted for about 10%, blank cylinder head and iron) accounted for about 30% ~ 35% blank cylinder head, accounted for the proportion is about 40% recycled waste, scrap iron accounted for under foot material proportion 60%, enterprises can not return direct sales (currently, only production enterprises can use recycled scrap iron). Total iron blank ratio is about 15% ~ 18%.
- Q:Coke can be used to do what carbon black can be used to do?
- Carbon black in plastics industry is the first use of carbon black pigment coloring, is cheap. Second carbon black in plastics industry use is to have good ultraviolet absorption effect, its application shows quite obvious protective effects in plastic. Third carbon black in plastics industry use is conductive.
- 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:What is the density of coke?
- Do you want to transport by rail? Ha ha, you might as well ask the freight forwarding clerk, he / she will tell you the various models of the volume and the weight can be installed, the conversion of the density of the pile is more accurate.
- Q:What are the requirements for the quality of coke in blast furnace smelting
- 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:What kind of coke is needed for smelting special steel
- The role of coke in blast furnace ironmaking can be summarized as follows: 1:(1) provide the heat: coke in the coke oven in front of the raceway in the intense combustion, combustion heat generated in the blast furnace smelting process is the main heat source(2) reduction: high temperature gas generated in coke combustion in the raceway, passed to the material in the process of heat rising, the endothermic reaction and coke formation, CO and H2, then CO and iron oxide in iron ore reduction reaction is transformed into metallic iron.
- Q:Ask: coking coke tower tower and what is the relationship?If you can give a working principle to explain what is better!Coking tower in oil coking plant
- Coking plant coal tower, primary cooling tower, cooling tower, etc.. The coal tower is used to store coal for coke oven. The cooling tower is used to cool the gas and cooling tower cooling water.
