Coke physical properties including coke sieve grouped into truth, coke, coke powder density depending on the relative density of density, coke, coke porosity, thermal conductivity for the heat capacity of coke, coke, coke, coke ignition temperature, coke thermal expansion coefficient of thermal stress and coke, coke shrinkage rate, coke resistivity permeability, etc.
- Q: Various types of coal coke are the main test items
- Coal test items which specific indicators of coal test:Generally include coal test indicators include: calorific value of coal (calorific value), sulfur content (sulfur), ash, volatile, fixed carbon, char residue characteristics, total moisture, water analysis and other indicators
- Q: What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you
- 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. Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
- Q: Coke is how to participate in the steel, and the pellets, sintering, a piece of the furnace in the furnace or in other containers
- Molten iron is produced in a reducing atmosphere of the blast furnace, which is then supplied to the steelmaking plant for steelmaking.
- 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: Some experimental results summarized the following two facts: the coke can not be used to restore aluminum mine, but it can be used for the reduction of copper and iron; no containing copper sulfate solution with tin, thus the activity sequence C, Al, Cu, Fe of the four elements is ______.
- There is no containing copper sulfate solution with tin. Because the copper iron can be displaced from the salt solution in their description, copper and iron;To sum up, we can know that C, Al, Cu, Fe four elements of the order of activity is Al > C > Fe > Cu;The answer is: Al > C > Fe > Cu.
- Q: What is the amount of waste gas produced by a ton of coke burning
- The coking coal is heated to 1000 DEG C under the condition of isolated air (high temperature carbonization)
- Q: Listen to a lot of people say that steel is now coke is not true?
- But at present, the iron making technology without coke has not yet been relatively mature, and it is not dominant compared with the traditional ironmaking technology. Coke industry still has development prospects.
- 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: Purpose of using coke in iron making raw materials
- The coke can provide the heat required for the reaction and has the reducibility
- Q: The coke is divided into several separate uses
- Gasification coke is used for the production of coke gas. The utility model is mainly used in a fixed bed coal gas producer with solid slag discharging, and is used as a gasification raw material to produce CO and H2 as combustible components. The main reaction of gasification process:C+O2 - CO2+408177KJ
