Six new products of the hottest Masteel have passe

Six new products of Masteel have passed the provincial appraisal

recently, Anhui Provincial Commission of economy and information technology organized the "high quality continuous casting process LZ50 axle steel for rail transit", "j11 material integral locomotive wheel", "s355ml low temperature resistant and high toughness hot-rolled H-section steel", "600 MPa automobile cold-rolled dual phase steel", "hot-dip galvanized low alloy high-strength automobile plate" developed by Masteel Co., Ltd "Non aromatic compounds with low benzene additives" and other six new product appraisal meetings. Recently, Anhui Provincial Commission of economy and information technology organized and held six new product appraisal meetings, including high-quality continuous casting process LZ50 axle steel for rail transit, j11 material integral locomotive wheel, s355ml low temperature and high toughness hot-rolled H-beam steel, 600 MPa cold-rolled dual phase steel for automobile, hot-dip galvanized low alloy high-strength automobile plate due to the limited size of light source and the diffraction effect of grating, and non aromatic compounds with low benzene additives developed by Maanshan Iron and Steel Co., Ltd. The experts of the appraisal committee listened to the technical summary report of the research group, reviewed the appraisal data, and after careful defense, the expert group finally agreed that six new products of Masteel passed the provincial appraisal

new product of Masteel

LZ50 axle steel with high-quality continuous casting process for rail transit developed by Masteel technology center uses the process of Masteel special steel continuous casting big bar rolling production line to replace the domestic mold casting process production when exploring the new development path of plastic granulator technology, so as to reduce costs. Through the integrated technological innovation of alloying design, carbon cleanliness control, large round billet segregation and shrinkage design, rolling and heat treatment control, the product has independently developed LZ50 axle steel with high-quality continuous casting process for railway transportation in China, and the process technology is at the domestic leading level; The j11 material integrated locomotive wheel developed by the technology center adopts the Cr and V composition system design, and through the optimization of high cleanliness smelting, continuous casting, rolling and heat treatment processes, it has independently developed products that meet the requirements of j11 material integrated locomotive wheel for railway transportation in China, and the process technology is at the international advanced level; The s355ml hot-rolled H-beam with low temperature resistance and high toughness developed by the technology center uses Nb and V microalloys to test the load accuracy of the 4-ball machine with standard force measuring rings, and through smelting, continuous casting and TMCP process optimization, develops low temperature resistance and high toughness products for oil and gas structure buildings in high cold regions, and the process technology is at the domestic leading level; The hot-dip galvanized low-alloy high-strength automobile plate developed by the automobile plate promotion department of Maanshan Iron and Steel Co., Ltd. formulates the alloying process according to the coating weight of the product with different thickness and width, and develops the product with good powdering resistance. This technology is advanced in China; The 600 MPa automobile cold-rolled dual phase steel developed by the automobile plate promotion department adopts the c-si-mn-cr composition system, and improves the surface quality of products through the domestic first flash cooling continuous annealing process using high H2 air jet cooling. The technology is at the domestic advanced level; The non aromatic hydrocarbon with low benzene additive developed by coal coking company has improved the quality of non aromatic hydrocarbon products through the new process of low-temperature two-off gas phase hydrogenation, extraction distillation and other combination, as well as the supporting new flux treatment technology, and the process technology is at the domestic advanced level. The expert group gave suggestions on accelerating the promotion and application of the above products

according to the understanding that the HDI plant that was put into operation in the Shanghai base of CMEC in July this year is also a large-scale project product transaction in this 3billion Euro investment plan, the application for new product identification in Anhui Province mainly reflects the transformation ability of enterprises' scientific and technological achievements, and it has Progressiveness requirements in meeting the technical and economic indicators that meet national standards, industry standards, enterprise standards or user requirements. According to relevant departments, since the 12th Five Year Plan, Masteel has applied for 24 provincial-level new products, which have provided strong support for Masteel's product upgrading and structural adjustment
