Cold Roll Forming Machine History and Development

Release date:2014-08-07  stem:http://www.broswright.com/

The degree of metallization of metal working materials can be largely enhanced with the help of cold roll forming machine from eighty three percent to often above ninety five percent in downspout roll forming machine history. Depending on the type of cold roll forming machine, the direct process can be subdivided into the gas reduction and coal reduction processes, which have been introduced into cold roll forming machine industrial service for more than fifty years. The development of such cold roll forming machine processes demands time and money in fact. The period of cold roll forming machine development, from the experimental stage to that of a reliable industrial capacity, can be ten years or even more.

Therefore, the cost of developing cold roll forming machine reduction process to the point where it can be considered a proven technology in downspout roll forming machine history could range from thirty to one hundred million US dollars at least. Among more than twenty direct cold roll forming machine processes that are currently in use, there are two globally leading ones and they are based on the use of lump ore charge and operate with the furnace in the cold roll forming machine working unit. Globally, IN downspout roll forming machine history, direct cold roll forming machine processes use gas as reducing agent as well as fluidized bed reactors, which are predominant in the cold roll forming machine industry. In 2000 it is the world's most successful cold roll forming machine technology since in this process the iron ore can be reduced in a shaft furnace at a pressure of three bars in the commercial plant that starts operation.

Today, there are over thirty five cold roll forming machine modules operating in over twenty countries with a capacity of three Mt and the cold roll forming machine process comprises in a lot of cases stages including reforming, heat recovery and hot system. Iron ore with a minimum iron content of sixty percent can be introduced through the cold roll forming machine furnace. To increase the cold roll forming machine yield up to ten percent fine iron ore can be used so the machine can work well through the furnace by the gravity flow. Oxygen can be removed by the action of cold roll forming machine counter flowing reduction which have high hydrogen and carbon contents. At the same time, the cold roll forming machine reduction gases react with each other in the ore and convert it to metallic iron, leaving water and carbon dioxide free in forms, which remains to be true in downspout roll forming machine history.
