Cold Briquette of Ferro-Contained Waste

Cold Briquette of Ferro-Contained Waste

2020-10-19

Iron and steel industry is an important source of solid waste. If these solid wastes are not utilized, it will not only occupy land, pollute the environment, but also waste limited resources. Steel and rolling system is an important source of solid waste in iron and steel enterprises. Its solid waste has high iron content. However, if it can be utilized, it can not only reduce environmental pressure, but also achieve the purpose of reducing cost and increasing efficiency. Judging from the application situation in the industry, the cold consolidation pellet metallurgy effect of converter dust removal ash is remarkable, which has the advantages of reducing the consumption of lime and other auxiliary materials, melting slag in advance, reducing the consumption of steel materials and the like, and has achieved remarkable results.

Two factors determine the strength of cold briquettes. One is the molding pressure, the material mixed with binder forms briquettes under the action of appropriate pressing force. The second is to let the green ball remove water and carry out carbonation reaction through certain drying and consolidation methods to improve its strength. There are many equipment used for drying, such as drum dryer, shaft furnace, consolidation tank, etc. According to the principles of high efficiency, convenience and economy, the advantages and disadvantages of various drying equipment are compared. We find that it is better to adopt the two-time curing method of grate reinforcement and tank formation.

Tea in China is divided into basic tea and reprocessed tea. There are six kinds of basic tea: black tea, green tea, black tea, yellow tea, green tea (oolong tea) and white tea. Reprocessed tea: It is made by reprocessing six major teas as basic raw materials. Including scented tea, compact tea, instant tea, tea drinks, etc.

Application of Magnesia in Foundry Binder(2)

As magnesium oxide is a magnesite ore that is calcine and then ground into powder, When the calcination temperature is 750-850 ℃, the content of magnesium oxide can become 75%-85%, of which only 60%-65% is active magnesium oxide. The activity of magnesium oxide gradually decreases with the extension of storage time. As the activity of magnesium oxide is an important basis for batching, it is necessary to know the activity of magnesium oxide when leaving the factory before batching. After leaving the factory and using for several months, the activity needs to be tested again. If it is left for too long, magnesium oxide will become magnesium hydroxide due to moisture, and the caked magnesium hydroxide has almost no activity, so it cannot be used, but it can be regenerated.

The ore powder treatment and processing used in ferroalloy smelting generally adopts pellet and sintering process, and the pellet is divided into pelletizing and pelletizing according to the pelletizing method. According to whether the pellets are roasted at high temperature and consolidated at low temperature after forming, they can also be divided into high temperature roasted, pre-reduced pellets and cold pressed pellets. At present, most of the fine ore treatment processes tend to pre-reduce and roast pellets. Cold-pressed pellets have the characteristics of low engineering investment, simple process flow, low labor cost and wide selection of powder particle size range, which cannot be replaced by other processes, especially in some enterprises with small investment scale and small powder ore treatment capacity.

Chinese Poetry

2020-09-28

Before the Tang Dynasty, the ancient poetry style was a style that did not pay attention to rules and regulations, nor did it limit the number of words and sentences. After the Tang Dynasty, due to the emergence of modern style poetry, in order to distinguish ancient style poetry from new metrical poetry, poets deliberately imitated the writing style of ancient poetry in the Han, Wei and Six Dynasties and limited it in some aspects, thus forming a fixed mode of ancient style poetry in the Tang Dynasty. The result is to change the completely free style of poetry before Tang Dynasty into a semi-free poem between metrical poetry and free poetry.

Synthetic organic binders for casting, such as furan resin and phenolic resin, are easy to release carcinogens due to incomplete combustion and pyrolysis during high-temperature molten iron pouring. Here we will discuss the environment-friendly and cheap inorganic binder magnesium oxychloride. The main component of its material is light burned active magnesium oxide, i.e. Magnesite ore. Its matching material magnesium chloride is a by-product of salt making industry. The combination of these two materials is inorganic hydrate material and has been used in many industries
