Hot Strip Mill lighting solution

The main task of the steelmaking plant is to desulfurize, dephosphorize, decarburize, and deoxidize the molten iron, and then cast the molten steel into steel billets. The hot rolling plant is an important step in the production of steel bars. It will make the steel embryos through hot rolling or cold rolling again after heating and rolling for several times, and then cut the edge and correct them to finally become steel plates.

Many hot-rolling workshops use relatively old-fashioned metal halide lamps. The lamps have low light efficiency, high power consumption, high failure rate, and large after-sales maintenance. They cannot guarantee the lighting needs of on-site production. In order to solve the lighting problems, our company is based on the actual situation. Summarize and solve the lighting problem of the hot rolling plant from the fundamental problem.
