On November 8, 2023, our company's after-sales technical personnel went to the "Sanmenxia Zhongyuan Key Metal Laboratory" to inspect and maintain the hydrogen reduction furnace designed and produced by our company. They patiently explained the operating instructions to the customer and guided the teacher on the techniques for replacing furnace tubes and installing new ones (to avoid uneven flange tightening and bursting of furnace tubes), and received recognition from the customer for our products.
