The high-temperature CO2 gas reacts with the carbon in the coke to form CO, and the CO further reduces the iron ore to form molten iron. Carbon supply: The carbon content of pig iron is about 4%, all from blast furnace coke, accounting for 7%-9% of coke carbon content. Heating: The combustion of coke, injected fuel and external hot air provide ...

Sendzimir Mill Intermediate Roll Maintenance . Because of its high rolling speed and precision, the Sendzimir mill is favored by some high-end users for rolling ultra-thin strips and silicon steel, stainless steel and so on. The mills of the Sendzimir mill use tool steel, abrasive steel, and high-speed steel.
Planetary Rolling Mills: The Planetary Mill is a medium output mill for rolling of steel strip. Its output is less than continuous mills of many stands but more than the reversing two-high or the three-high mill. This mill can be used to roll all metals but it is especially useful for those which have low ductility.
What is the New Technologies for Bar Rolling Mill? (1) The full short stress no-twisted rolling mill. At present, the international advanced production line, like the ABSIWNA plant in Italy, uses the full short stress path rolling mill line with H-V-H-V arrangement. (2) The large size billet material and low in energy consumption.
Headless rolling has a series of obvious advantages, such as high production efficiency, improving dimensional accuracy by reducing the loss of cutting head and tail to improve the yield, overcoming the dimensional deviation of the head and tail of the rolling piece, reducing the impact of the head and tail of the rolling piece on the motor, transmission system, roll, …
Advantages: Hot rolling can greatly reduce energy consumption and costs. The metal plastic deformation is high during hot rolling, and the deformation resistance is low, which reduces the energy ...
5. Cluster Rolling Mills: In this type of rolling mill, there are two basic roles that are backed up by two or more rolls which are bigger than those two basic rolls. These backed up rolls give more pressure to the basic rolls to heavily press the strip.
