Barge heavy industry LPG ship construction is getting better
LPG No. 3 started on May 15th, boarded the shipyard on August 27th, and floated on the dock on October 26th. The ship's cycle was 64 days, which was half the time of the LPG No. 1 shipyard cycle.
During the construction of the ship, Barge Heavy Industries seriously summarized the construction experience of the first two ships of the same type, strengthened technical research, and established a special research group composed of technical, production and management personnel. With the “paper-making shipbuilding†as a means, the entire product construction requirements are solidified by establishing a construction policy. Comprehensive and meticulous preliminary planning of the hull structure and liquid tank manufacturing process, and the preparation of the liquid tank assembly welding process and the ship construction process. At the same time, the implementation of the all-round production of parallel carcass segments, to achieve the process of no-quantity manufacturing forward, further strengthen the integrity of the segmental shell, enamel and coating integration, the segment pre-assembly rate has reached 90% .
In accordance with the principle of “construction of shipbuilding, socialization of production, and localization of supportâ€, Barge Heavy Industries actively promotes the method of final assembly and shipbuilding in the construction of the ship, and conducts external production for segment production and liquid tank production to ensure excess The production load can be diverted. The liquid cargo tank and the main hull are separately constructed, the liquid cargo tank reaches the overall test water, the armor is completely finished, and the complete intermediate product is formed; the main hull is constructed according to the 5 major sections, and the total section armor is completely finished to reach the intermediate product finished product. Finally, it is finally formed in the floating dock.
According to the task arrangement of the four production lines, the barge heavy industry rationally utilized the construction of 100,000 tons of the total group site on the basis of balanced production resources, and launched the newly opened third ship channel, the floating dock, to maximize the current situation. There is resource utilization. The company strengthened on-site control to make the product quality rise steadily and the production pace was significantly accelerated, which made the ship build a new record.
At present, the ship is carrying out work such as mainframe installation, diesel engine and anchoring machine debugging, and actively creates conditions for navigation experiments.
Milling machines have features with high precision, high working speed and stable performance in cavity on ISO IC card, telecom card and dual interface card.
While embedding machines are easy to be maintained and operated. They are used for chip punching and put different chips in the cavity, to realize IC card embedding process.
YUANMINGJIE technology creates full auto Milling And Embedding two in one machine, which combines functions of milling and embedding machines. Milling and Embedding two in one machine can not only make millings we need but also can test, punching and implant different model of chips in cavities.
