Circular Platelike Johnson Screen is a kind of Platelike Johnson Screen. The support rods and V-type wire are connected together by contour welding. The surface wire is also called V-type stainless profile wire or wedge-shaped wire.
The outer diameter, the width of support rods, the size of the slot opening and the width of V-type wire can be customized according to the requirement of customer. We mainly use stainless steel for this circular platelike Johnson screen.

In recent years, although some achievements have been made in the localization of metallurgical equipment in China, there is still a big gap compared with the development of the metallurgical industry itself. The import ratio of major equipment required by many metallurgical industries is still relatively large.
Wang Jianye, chairman of the China Heavy Machinery Industry Association, believes that the development process of metallurgical equipment can be seen (see related links for details). Insufficient innovation has become the crux of localization.
In the past ten years, 11 sets of hot rolling strip rolling mills in China have adopted the most advanced technology and equipment in the world. According to the drawings of foreign equipment, China's relevant manufacturing plants have processed and manufactured about 85% of mechanical equipment, but the core technology has not yet been mastered by the Chinese.
Since the beginning of this year, despite the great progress made in the localization of equipment, the momentum of the introduction has not diminished and the localization of key equipment has been slow. Rely on engineering mode to achieve results
In order to implement the instructions of the State Council on “Relying on Major Engineering Projects and Accelerating Autonomous Design and Manufacturing of Rolling Equipment,†Anshan Iron and Steel has realized the localization of large-scale cold-rolled sheet rolling equipment, and the National Development and Reform Commission has organized large-scale organizations since 2005. Thin plate hot rolling plant equipment localization work. If relying on the 1750 mm hot strip mill project of Tianjin Tiantie Hot Rolled Sheet Co., Ltd., it supports the formation of a consortium of the Second Heavy Machinery Group Corporation (hereinafter referred to as Duplex) and the MCC CCID company for the general contracting of equipment and technology. At the same time, in order to give full play to the intellectual resources of domestic scientific research institutes, the consortium cooperates with Beijing Science and Technology University and Yanshan University, which have leading levels in this field, to jointly develop technologies such as rolling technology, key equipment design, process control, and key component manufacturing. Research. The total equipment weight of the Tianjin Tiantie Hot Rolling Plant reached 16,470 tons, and the total price of the full set of equipment contract was 728.5 million yuan. At present, the project has started construction in an all-round way.
At the same time, Shuanghe signed the contract for exporting 2250mm sheet hot continuous rolling complete sets of equipment exported to Poland worth more than 39 million U.S. dollars in 2005, setting a precedent for the export of China's large-scale hot strip rolling equipment to Europe. Recently Turkey, India and other countries have Intention to order double sheet hot strip mills.
At present, the National Development and Reform Commission is actively promoting the localization of the large-scale hot strip rolling equipment implemented by Erzhong and China Metallurgy, and making it a competitive general contracting and design manufacturing consortium, forming a core of independent intellectual property rights. The technology will promote the implementation of technological transformation of the old rolling mill and the upgrading of hot strip rolling products by the metallurgical enterprises. At the same time, it will realize the export contracting of large-scale complete hot strip rolling equipment and participate in the international market competition.
Some equipment development breakthroughs
From 2002 to the present, some mechanical companies have joined hands with iron and steel companies to achieve a number of new breakthroughs in China's independent research and development of metallurgical equipment, mainly including: Anshan Iron and Steel Co., Ltd. and Yizhong Co., Ltd. have successfully developed 1,700 mm hot rolling with independent intellectual property rights in 2002 and 2003 respectively. And 1780mm cold rolling two sets of large-scale complete sets of equipment; Shougang and Shuanghe cooperated in the successful development of 3500 mm plate mill in 2003, to provide technical support for the production of China's shortage of plate; Baosteel and Xi'an Heavy Machinery Research Institute The developed molten steel RH vacuum refining equipment has been promoted and applied in China; Beijing Steel Research Institute and Yanshan University have successfully developed the relevant rolling mill plate type control technology, which has also been applied in Panzhihua Iron and Steel and other enterprises; Xi'an Heavy Machinery Research Institute cooperates with private enterprises in Shandong The successful development of the 10,000-ton oil extruder required by the metallurgical industry provides good equipment for the extrusion of large and precise metal sections.
