Usage/Applications

Cupola isthe most common type of melting furnace used in the foundry industry. Heat,released from combustion of Foundry coke in the bed, melts the metallic charge materials.Cupola operators depend upon foundry coke for several reactions in their meltunits:
● Energy to support the melting of the iron, alloys and fluxes in any givencharge
● Carbon pick-up as the iron drips past the coke bed area upon melting

Main Features of the Product

● High fixed carbon

● Low sulphur

● Ready to ship in stock

Inspection

Q: Effect of coal fineness on coke: From the point of view of the uniformity of coal material, the more finely pulverized coal. But if the coal fineness is small, because of the presence of a larger particle weakly caking coal and ash and coke cracks increased, the uniformity of deterioration. If the particle size of coal is not uniform, it is easy to produce segregation phenomenon in the transportation process, the grain size of different size will be gradually stratified by size. Due to the different coal hardness of the coal blending, large particles of coal is often a greater hardness of coal, so the segregation phenomenon, will make the different coal species gradually separated, so that the uniformity of coal deterioration.

Q: What is the difference between coking coal and coke: Coking coal is an essential raw material for the production of coking coal, coking coal is one of the main uses of coke, coke is full of coking coal, coking coal is necessary for coke.

Q: How coal is turned into coke in the coking chamber: Simply put is to let the coal in the isolated air furnace heating, volatile volatile, and the rest is cokeOf course, the volatile ingredients to be collected, are the baby

Q: Who knows the proportion of pig iron and coke used in Cupola: There are doubts: if the scrap ratio is too large to increase the difficulty of processing, product quality can not be guaranteed. The proportion is too high or too low are abnormal.2, auxiliary material input: foundry auxiliary materials mainly coke. Ordinary casting (except dry cylinder) 1 tons ~ ~ 5 tons cupola, each investment of 1 tons of coke, according to the situation of the piece can be from 4.5 tons to 5.5 tons. Ordinary blank (special pieces extra), 5 tons to 10 tons per 1 tons of coke in cupola furnace about 6.5 tons to 7.5 tons of blank (waste products re melted are calculated according to the above method).

Q: What is the use of coke: From the distribution of coke production in China, the distribution of coking enterprises in China is unbalanced, which is mainly distributed in North China, East China and northeast china. Three, the use of coke coke is mainly used in blast furnace ironmaking and copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting furnace, reducing agent, heating agent and the role of the material column skeleton. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. 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: What is the difference between the industrial analysis of coke and the industrial analysis of coal samples: Quite a lot! You'd better look at the standard coal GB/T212-2008,

Q: What does the M40% and M25% mean in the analysis of coke?: (1) crushing strength (shatter strength): the ability of a certain particle size coal sample to fall under the condition of free fall.

Q: The coke is divided into several separate uses: Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. The metallurgical coke quality standard (GB/T1996-94) developed in China is the quality standard of blast furnace.

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
