Barge Heavy Industry Deepens the Transformation of Shipbuilding Mode

Since the beginning of the year, Bohai Shipbuilding Heavy Industry Co., Ltd. has continuously deepened the transformation of shipbuilding mode on the basis of consolidating the results of the previous “transformation model” in accordance with the requirements of “The Group established a modern shipbuilding model from 2009 to 2011”, and vigorously advocated refined design and fine Chemical management, refined production concepts, and vigorously promote the innovation of technology and engineering methods. Recently, the company's 58,000-ton bulk carrier No. 9 ship realized the launching node 56 days after the ship's berth, which met the standard of 60 days for the group's required ship-to-ship cycle, marking the improvement of ship standardization construction technology of Barge Heavy Industries. Construction efficiency has improved significantly.
During the construction of the 58,000-ton bulk carrier No. 9 ship, on the basis of summarizing and perfecting the experience of the previous series of shipbuilding, the barge heavy work carried out scientific analysis on the whole process of shipbuilding, and explored the favorable space for further release of production capacity and improved The construction efficiency of the ship. First, further strengthen the preparation of pre-production technology, increase the amount of segmentation, and strictly control the precision in the segmentation process to improve the quality of the production of individual segments. Second, in the case of limited production resources such as shipyards (docks) and cranes, rationally plan the sub-segment site, comprehensively and systematically optimize the overall group plan, discuss the feasibility of the total group plan, and expand the segment before the ship's berth. Total amount. The 58,000-ton bulk carrier ship No. 9 has 141 sub-ships, and the total number of participating segments has reached 116, forming 35 total segments, and for the first time, the sub-group of the rudder area of ​​the series of ships and rafts has been realized for the first time. Work, expanding the total segment of the cabin area. Thirdly, under the premise of fully considering the technical feasibility and material preparation, the armoring machine, the cable cutter and other armoring work will be completed ahead of time, and the inspection items that meet the conditions will be completed in the general group stage, and the process will be vigorously promoted. Move work.
At the same time, with the implementation of the PSPC specification approaching, on the basis of the agreement with the shipowner and the ship inspection, the heavy-duty work of the ship was carried out in the total group stage of the ship's shipyard. The broad-scale promotion laid the foundation and provided a solid technical guarantee for the further shortening of the shipbuilding cycle.

Cement Manufacturing Equipment

There are mainly two different processes for cement making, wet cement production line and dry cement production line, however dry type cement manufacturing process is more popular nowadays, and there are two solutions for dry cement manufacturing process, one solution is with vertical shaft kiln and the other is with Rotary Kiln, generally speaking A complete cement production line mainly includes three processes: raw material preparation, calcination process, clinker grinding and packing process, and the main cement production equipment consists of crusher, raw mill, rotary kiln, cooling machine, Cement Ball Mill, packing machine, Dust Collector, Belt Conveyor , bucket elevator, and so on. the capacity ranges from 50-3000 tpd.
