Steel plates for domestic Fischer-Tropsch reactors passed the review

At the end of last month, the steel plate SA387Gr11CL2 for the Fischer-Tropsch reactor of the coal-to-liquid core unit jointly developed by Wuyang Iron and Steel Co.
, Ltd.
of HBIS and the Coal-to-Liquid Branch of Shenhua Ningxia Coal Industry Group Co.
, Ltd.
passed the expert review and became the domestic petrochemical equipment for China Add another weight
.
? The expert group organized by the Major Equipment Office of the China Machinery Industry Federation and the Pressure Vessel Branch of the Chinese Mechanical Engineering Society listened to the steel plate technology research and development report and the first report made by the coal-to-liquid branch of Hegang Wugang and Shenhua Ningxia Coal Industry Group Co.
, Ltd.
The report of the tripartite inspection report and the novelty search report, after questioning and discussion, gives the review opinion: the J coefficient, X coefficient control, mechanical properties, low temperature impact toughness and other properties of the steel plate are equivalent to the performance of the steel plate produced by the world's advanced steel companies.
Some indicators such as coefficient are better than foreign steel mills
.
? Shenhua Ningxia Coal Group's 4 million tons/year coal-to-liquid core device-8 sets of special steel plates for Fischer-Tropsch reactors, is a key material for localization urgently needed in the project
.
This kind of steel plate design requirements: the material is SA387Gr11 hydrogen-containing chromium-molybdenum steel, compact and good internal quality, good toughness reserve, uniform plate surface and plate thickness performance, stable medium and high temperature performance, and maximum simulated post-weld heat treatment temperature of 690 ℃, heat preservation for 24 hours, long-term simulated welding, -10℃ impact toughness not less than 80 joules
.
These design requirements make it extremely difficult to produce plates
.
HBIS Wugang adopted key process measures such as optimized composition design, grain refinement, uniform structure, and simulated post-weld heat treatment, and successfully produced a 132 mm thick hydrogen steel plate SA387Gr11CL2 that satisfies the performance requirements.
The company's container steel research institute Chang Yuan Jincheng introduced to reporters that the hydrogen-producing steel plates produced by HBIS Wugang have been used in Shenhua Ningxia Coal, Shaanxi Future Energy, and Shanxi Lu'an coal-to-liquid Fischer-Tropsch reactors, with a consumption of 40,000 to 50,000 tons
.
? It is reported that the hydrogen-prone steel sheet SA387Gr11CL2 has also been widely used in coal gasifiers, with a thickness of 70-132 mm and a supply of nearly 10,000 tons.
The quality level meets the needs of the project, and the performance has reached the international advanced level
.
In terms of the development of large-thickness high-end hydrogen-producing chromium-molybdenum steel sheets, we realized batch supply of 168mm, 174mm, and 177mm-thick high-end hydrogen-prone chromium-molybdenum steel sheets.

.
162 mm and 177 mm thick steel plate SA387Gr11CL2 realizes the domestic production of steel for ammonia synthesis towers in China
.
The domestic largest thickness of 200mm hydrogen-containing chromium-molybdenum steel plate has been applied to the Sinopec's Maozhan world-class refining and chemical base Zhongke Refining and Chemical Project, which is used to produce its core equipment, a thermal high pressure separator
