Main features of foundry coke
1. The foundry coke is made by China best coking coal resources in Shanxi provience
2. The foundry coke has high fixed carbon, enables to provide enough heating.
3. The foundry coke has low sulphur, secure the quality of iron castings.
4. All kinds of size are available.
Cupola is the 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 melt units:
1. Energy to support the melting of the iron, alloys and fluxes in any given charge
2. Carbon pick-up as the iron drips past the coke bed area upon melting
Packaging & Delivery
Foundry coke is to be packed in bag or loose in container.
loading of foundry coke in one ton bag
loading of foundry coke loose in container
- Q:Who knows what the provisions of the coke train sampling country?
- Test procedureDetermination of total moistureA, said the samples size less than 13mm with pre dried and weighed for about 500g (referred to 1g), smooth specimen,B, a sample tray is placed on the 170 a 180 C in the drying box, LH removed after cooling, weighing 5min. C, check dryness, each time 10min, until the two consecutive quality difference in LG, calculate the quality of the last time.Determination of moisture content of samplesA, with the weighing bottle drying to constant quality in advance and has quickly called weighing samples size less than 0.2mm uniform mixing of the 1 + 0.05g (referred to 0.0002g), flat on the weighing bottle.B, will be filled with a sample of the bottle to be placed in the 105-110 drying box drying 1H, remove the weighing bottle immediately covered with lid, put into the dryer to cool to room temperature (about 20min), weighing.C, check of dry, insult 15min, until two consecutive poor quality in 0.001g, take the quality of the last calculation, if quality is weight gain first calculated on the basis of.Five, the calculation of test resultsCalculation of total moisture content according to formula (L):
- Q:The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace,
- Coke strength index is divided into cold strength index and thermal strength indexCold strength index: M40 M25 M10
- Q:What does Coke test index M25 mean?
- 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. Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand in about 30%. Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance
- Q: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.
- Q:China's coke iron smelting began in what time?
- The ancient iron smelting method in smelting iron block, lower temperature, iron ore solid reduction sponge iron, and iron into play by forging. Smelting iron block, furnace, furnace with ground and shaft 3. The block iron making in our country began in the spring and Autumn period, and in the near future, the pig iron with more than 2% carbon dioxide was refined and used as a casting tool
- Q:Natural gas can replace coke smelting pig iron
- No, because the coke in the blast furnace to heat, reducing agent, skeleton and carbon supply four functions
- Q:Sulphur content of coal and coke,
- 80% to 90% of the sulfur in coal into coke, the other into the coke oven gas.
- 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:What is the effect of coke moisture on the blast furnace?
- 2, if the long-term use of water containing high coke and blast furnace gas purification system and dry, it will affect the normal operation of the purification system (filtration pressure increased, serious and even lead to normal filtration, also lead to dust can not be normal unloading etc.); more serious for the blast furnace with net gas said not even a normal discharge (top pressure tank or a pressure higher than indoor clock dozens of kPa
- Q:Coke is how to produce, what is its purpose?
- Coke is a color of deep gray to black solid, soft; internal structure of porous, and sometimes can be six square column.
