On December 10, 2019, at 3 p.m., the 1.0-3.0X750 galvanizing project of Tangshan Beijing Cold Rolling Galvanizing Co., Ltd., which was constructed by Beijing JJRS Technology Development Co., Ltd., was officially put into operation. The production of the products was a complete success, and the quality of the galvanized sheet was qualified. 

This annealing furnace is designed based on the improved Sennikirme镀锌 process technology. It can meet the galvanizing production requirements and can heat， heat-treat， cool and homogenize the steel strip according to different heat treatment curves of each， complete the recrystallization annealing of the steel strip and make it reach the required temperature before entering the galvanizing tank， featuring high quality， high efficiency and low consumption.
