NO8810 nickel-based alloy plate is the main material of the photovoltaic industry cell plate polysilicon production equipment, the material is resistant to high temperature and high pressure, high wear and strong corrosion resistance and other performance requirements, in order to achieve a breakthrough in the industrial development of nickel-based alloy materials, the rapid realization of the product scale production, the plant 3300mm production line to "strive to create the ultimate benefit "To achieve the breakthrough in the industrial development of nickel-based alloy materials and to quickly realize the large-scale production of this product, the plant's 3300mm production line aims to "strive for the ultimate efficiency" and focuses on the mass production of nickel-based alloy varieties.
By optimizing the process flow and implementing scientific methods such as flaw detection before product heat treatment, the whole process can be controlled to minimize energy consumption, improve the rate of finished products and reduce invalid inputs. In the actual production process, the site limitations lead to low efficiency of steel plate polishing. In response to this problem, the plant firstly, widens the production site and forms a commando team to level the ground. Secondly, the production management personnel were organized to seek a breakthrough to further optimize the production organization and achieve manual polishing of some nickel-based alloy steel plates, which effectively improved the efficiency of steel plate polishing operations.
Nickel-based alloy steel plates have strict requirements on the time and process of heat treatment, and the existing heat treatment equipment is difficult to meet the requirements of high output. In order to solve the problem of insufficient heat treatment capacity of the existing normalization furnace, the attack team was divided into two ways, on the one hand, to attack the heat treatment capacity of No. 1 normalization furnace, timely development of the adjustment plan to improve the thickness of heat treatment steel plate, 24-hour follow-up tests at the site, and finally achieve the maximum thickness of heat treatment steel plate from 50mm to 60mm, to overcome the heat treatment "bottleneck ". On the other hand, the innovative design of No. 1 heating furnace and the implementation of water-cooling facilities transformation, open up the continuous solution heat treatment production process in No. 1 heating furnace, to maximize the efficiency of heat treatment.
In addition, under the joint efforts of the attack team, a series of other production processes have also achieved innovative breakthroughs: the heating process has been further optimized, and the heating of 44mm thick steel plate is carried out by means of furnace head burning, which effectively reduces the tendency of thin gauge steel plate billets to burn and bend; the process innovation is implemented, and the composite billet making process is adopted for continuous casting billets, which reduces the cost of billets and solves the problem of low flaw detection rate of grinding and casting billets; the optimization of billet The output of nickel-based alloy steel plate N08810 and N08120 in the 3300mm production line has increased exponentially, and the cold hydrogenation reactor of N08810 material has been delivered, successfully realizing the mass production of this product and "domestic substitution". domestic substitution".
