Lin Feng Aluminum Power Co., Ltd.: Technological innovation is everywhere to boost lean management and upgrade

Since November, Linfeng Aluminum Company has carried out lean management activities. The workshops focused on the theme of the activities, conducted in-depth discussions, and vigorously implemented technological innovations. Through technological innovation, "blossoms everywhere," boosting the lean management of enterprises to upgrade files.

The electrolysis workshop vigorously promoted the operation of car grabbing and slagging, which greatly reduced the labor intensity of the urination. The electrolysis workshop is equipped with grabs for multi-functional traffic for large surface shells and poor carbon salvage when changing poles. Through grab operations, the efficiency is greatly improved, saving time and effort. In the next step, the electrolysis workshop will further advance the technological innovation of automatic aluminum fluoride addition.

Phosphorus and iron ring pressure in the assembly workshop was changed from side-by-side to tandem row, which greatly reduced equipment operation time. Phosphorus and iron rings are used to place two pressures in the north-south direction. The traffic cannot be off-line at the same time, resulting in low efficiency in off-line work. It is now placed east-west and the equipment can be operated at the same time, which greatly shortens the equipment operation time and improves the sharing efficiency of belts, dust removal equipment and other equipment. The two pressure-off personnel achieved an optimized combination, which was reduced from 4 to 3 people. The assembly shop also optimized the casting process. The ladle package was changed from small to large, and two 1.5-ton ladle packages were used instead of three one-ton ladle packages, which also reduced the number of intermediate-frequency furnace packages and reduced the time for traveling and lifting.

Casting workshops and transportation workshops promoted heat-clearing packages instead of cold-cleaning packages, which greatly reduced the labor intensity of workers. It was originally a deserted package. It takes one day for one person to clear one package. After changing to a hot pack, one person can clear 3 packs in more than 2 hours. In the next step, the foundry will speed up the progress of the automatic saw bar technology by sawing one, realizing multiple saws and increasing the saw blade efficiency by more than five times.

Power supply workshop to promote power supply, computer centralized monitoring. The power supply workshop relocated the network cable to move all the computers in the computer room to the power supply control room. The two sets of people and horses were combined to achieve the optimal combination.
