it is not the time to close to prevent the nickel plating steel plate of the device and the manufacturing method

摘要

this invention is to be in the date of the direct heat treatment of the nickel in the nickel containing gas, the production of the steel are easy to occur between the close, in order to prevent. nickel and the cold rolling of the steel city of the formation of more than 0.5 - 10 u339b thickness of nickel iron diffusion layer and the largest thickness of 0.5 - 10 u339b have nickel plating layer, and the coating weight, and a silicon u338e / u33a1 2.5 0.1 - the uc704uc5d0 form on the silicon oxide layer box. the cold rolling process, the nickel and the nickel plating layer, a silicon hydrate on the coating in order to sodium loss. kate is the main ingredients in the use of nickel or the impregnation of the electrolytic process in the heat treatment is made, and with me.
