To further enhance DRI for steelmaking, it can be converted to pig iron or hot metal via melting. There are existing processes in the industry that use electric energy in furnaces such as submerged arc furnaces to convert DRI into hot metal. Air Products’ novel DRI melting process uses oxy-fuel combustion in place of electric power to accomplish this melting. Figure 4 provides a process diagram (patent pending) .

Advantages of charging DRI hot coming out of the shaft reactor have been well documented, namely productivity increase and decrease in power use. Few DRI plants in the world have the ideal setup with an EAF downstream of the DRI plant, where the DRI coming out of the shaft furnace can be charged hot into the EAF.

Direct Reduced Iron (DRI) is the second most viable source of virgin iron used in steelmaking after pig iron or hot metal produced in blast furnaces. DRI is produced by direct reduction of iron ore using carbon monoxide and hydrogen. Natural gas-based shaft reactors are commonly used in North and South America for DRI production while coal-based DRI is common in Asian markets. Inexpensive supply of natural gas in the United States makes DRI an attractive source of iron for steelmakers.

In the use of high-pressure briquetting machine and other briquetting equipment, we often encountered the motor heating, even burnt failure. What are the main causes of these failures and how to maintain them? Luoyang Kaizheng's engineers will analyze for you that how to make your briquetting equipment have a longer service life, lower failure rate, and more economic benefits.

In the production of float glass​, the mixing process is a very important link in the production of the mixture, and the mixer is also a very important key piece of equipment. The correct selection and use of the mixer is the basis for improving the quality of the mixture and ensuring the stable quality of the glass.

Since the tailings are very fine in size, it is more reasonable for the raw tailings to be pelletized followed by direct reduction roasting. In order to investigate the possibility of iron recovery by direct reduction roasting of carbon briquette from high iron tailings, the effects of different binders on the green briquette strength and high temperature strength of carbon briquette from high iron tailings were studied.

Given the current problem of limestone solid waste treatment in steel mills, two briquetting treatment techniques and methods are introduced. It is suitable for the recycling of limestone mud cake in steel mills to realize the recycling of dust and sludge generated in its production process.

Material mixing refers to the homogenization of one or more materials to reduce or eliminate the uneven distribution of particle size, density, temperature and plasticity. It is a common material processing method.

Different industries use different mixers​ due to different types, characteristics， using and subsequent treatment methods of raw materials. The selection of a suitable mixer for compound fertilizer production plays an important role in ensuring the smooth progress of production and the final quality of products. The editor will show you how to choose a suitable mixer for compound fertilizer manufacturers.

For cold-consolidated pellets, molasses can be used alone as a binder, some of which may need to be diluted during use and a certain temperature is required. Molasses can also be used as a binder together with other materials. For some pellets that need special use, molasses may also be used as the main raw material to add other materials to prepare a binder with composite properties.
