Stainless steel has high deformation resistance, generally twice that of ordinary carbon steel. During cold working, deformed martensite forms, causing a rapid work hardening rate and requiring greater rolling force and load. Requirements Stainless Steel Cold Rolling Mill Should Meet Work rolls should be of small diameter as much as…
Roll flaw detection is essential for almost all high-standard rolling mill. Common methods for roll flaw detection include magnetic particle flaw detection, penetrant color flaw detection, eddy current flaw detection, and ultrasonic flaw detection. Magnetic Particle Flaw Detection: This technology is primarily used to identify surface cracks on the roll body…
New-product: 1100MPa High-strength Solid Wire At present, there isn’t a matching welding material with the1100MPa high-strength steel plate, most of the industry is forced to use 900MPa grade wire, in the design to avoid the welding joint force, which brings more trouble to the equipment design, but also is the…
In ironmaking production, maintaining the stability of blast furnace operations is crucial. Key parameters influencing this stability include furnace temperature, ore batch weight, slag alkalinity, charge ratio, wind pressure and temperature, and top pressure. Furnace temperature Maintaining stable furnace temperature helps keep the drop zone height proper, stabilize the differential…
Under the condition of using solid carbon fuel (coke + pulverised coal) in conventional blast furnace, reducing carbon fuel consumption is the most direct and effective measure to reduce CO2 emission. In the iron and steel industry, by around 2030, the fuel ratio of blast furnace should be generally reduced…
Blast furnace is a black box, how to understand the various changes within the blast furnace well, one way is to reference the anatomy of the blast furnace, supplemented by a variety of theoretical calculations and practical experience to deduce the changes within the furnace; another way is to apply some visualisation technology to…
Blast furnace charging operation refers to the control of the position and thickness of the furnace charge in the blast furnace production process, so as to adjust the key technical and economic indicators such as the permeability of the charge column and the utilisation of gas. The charging system is…

Blast furnace ironmaking is a dominant process in the ironmaking industry, known for its mature technology and significant output advantages. More than 90% of the world’s iron is produced using blast furnace ironmaking. This process is divided into nine major systems based on their functions. 1.Raw material system The primary…
On April 21, 2024, the Shanghai Metallurgy Equipment Group (SME Group) was honored to host His Excellency James Kimonyo, the Ambassador of Rwanda to China. The visit signifies a pivotal moment in the development of our company’s international relations and marks the beginning of a promising partnership. During the ambassador’s…
