Gas system of blast furnace mainly includes gas purification, TRT (blast furnace gas (waste heat) turbine power generator) and blast furnace gas discharge tower, etc. Blast furnace gas purification adopts dry bag dust removal, that features high dedusting efficiency, no water consumption, low energy consumption and high automation. After the…
Thermal system in blast furnace project include blower station, cold air, steam and compressed air devices. The axial flow blower has the advantages of high flow rate, high efficiency, wide operation area, light weight, small size, etc., which can be adapted to the operating requirements of the blast furnace with…
The public and auxiliary facilities of blast furnace ironmaking mainly includes storage and transportation of raw materials and fuel facilities, thermal facilities, gas facilities, water supply and drainage facilities and HVAC facilities. At project preliminary design, the storage and transportation facilities for raw materials and fuel are divided five sectors.…
Reducing pollutant emissions is a significant challenge for all ironmaking plants. The key is to control the emissions from processes that generate large amounts of discharges. From the initial design phase of a new project or the reconstruction of a blast furnace, it is crucial to carefully consider suitable solutions…
The fuel ratio in small blast furnaces exceeds that of large blast furnaces, a phenomenon determined by fundamental principles in metallurgical physics and chemistry. Small blast furnaces, characterized by their squat design, have shorter material columns compared to large blast furnaces. Consequently, the gas heating of the charge is insufficient,…
Ferritic stainless steel is known for its high corrosion and oxidation resistance, but it has lower plasticity and toughness. Common grades include 409 and 430, which are mainly used in automotive and construction applications. Magnetic Properties: Ferritic stainless steel is magnetic. Thermal Expansion: The thermal expansion rate of ferritic stainless…
A single cold rolling mill can handle small-scale rolling tasks with lower initial equipment investment. Its production organization is more flexible, allowing for quick adjustments to specifications based on market demand. The old system’s operation and production process relied heavily on operator input setting and field adjustments, with fault diagnosis…
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…
