Bar And Wire Rod Direct Rolling Technology without Heating

The technology of direct rolling without heating of bar and wire refers to the technology of directly sending the slab with residual heat after continuous casting into the rolling mill line for rolling. When the heating-free process is used, the billet does not need to be heated in the furnace, and it does not need to be reheated (some of which replenishes the corner parts through the electromagnetic induction device), completely eliminating the fuel consumption of the heating furnace, which can greatly save energy and reduce carbon dioxide of emissions.

Relationship between Daily Working Efficiency of Rolling Mill and Ambient Humidity and Temperature

It has been proved by practice that environmental factors are also included in many factors affecting the daily work efficiency of the rolling mill, mainly the humidity and temperature of the environment. Therefore, in order to improve the working efficiency of the rolling mill, the narrow outlet of the heating furnace has strict requirements on humidity. In the case of no tapping, closing the furnace door can reduce air consumption and heat transfer, and reduce the cost of coal or gas.
