Project Overview

Following the loading and shipment on September 26 and 27, 2021, the automatic enameling line for Zhengzhou Haier's water heater liners undertaken by our company was shipped again on October 29, 2021. On-site installation is proceeding simultaneously with shipment, and the installation is currently progressing smoothly. The line is expected to start operation in early January 2022.

This automated, informatized, and intelligent automatic enameling production line for water heater liners is the 15th such automated enameling production line for water heater liners provided by our company to Haier Group's water heater production bases.

The "Automatic Enameling Production Line for Water Heater Liners" integrates our company's more than ten years of rich experience in the water heater industry and adopts dozens of our invention patent technologies. The project uses dual-station robot automatic loading, intelligent workpiece conveying via accumulation chains, three-station robot automatic unloading and enameling, and three-station robot automatic transferring and firing. For wet enameling of liners, technologies such as waste heat drying from firing and automatic firing are applied, with the overall production cycle of the line reaching 18 seconds per unit.

This project boasts numerous advantages, including high automation, informatization, and intelligence, low labor input, fast production cycle (18s/unit), high production efficiency (up to 200 units/hour), good production environment, low comprehensive energy consumption, high visibility for visits, environmental friendliness, strong production versatility, high flexibility, and small footprint. The enameling furnace uses natural gas heating, with its "core component" adopting German original imported 601 high-temperature resistant alloy steel P-type radiation tubes combined with self-preheating high-efficiency energy-saving burners and other latest energy-saving and environmental protection technologies. Meanwhile, the energy-saving technology of waste gas waste heat utilization ensures the enameling furnace has advantages such as low energy consumption and good temperature uniformity.

After putting this production line into operation, it will become another classic of advanced technology production line equipment in the water heater industry, following the first-phase automatic enameling line for air-source heat pump water heater liners of Zhengzhou Haier.
