On September 3, the SME team was honored to participate in the Forum on China-Africa Cooperation – Djibouti International Free Trade Zone Forum held in Shanghai. This forum, strongly supported by…
This article is excerpted from a speech by Mr. Liu, chairman of SME Group Powerful person have many dimensions and criteria, but the most critical one is to see whether the person has the ability to solve problems and be a buster of tricky troubles. Behind the hidden is a valuable quality to have strong…
Cold-rolled sheets have good surface quality, high dimensional accuracy and no oxide sheet due to rolled at room temperature. After annealing treatment, its mechanical properties and technological properties are better than hot-rolled sheet, mostly used of automotive, electrical products, locomotives, aviation, precision instruments, food and other industries. In the planning and design…
1Cr17Mn6Ni5N stainless steel is instead of grade 1Cr17Ni7, it is with magnetic properties after cold rolled, used for railroad cars. 1Cr17Ni7 stainless steel has high strength after cold working for railroad cars, conveyor belts, bolts and nuts. 1Cr18Ni9 stainless steel has high strength after cold working, but the elongation is…
The blast furnace feeding system includes coke belt, ore belt, material surface measuring device, and dust removal device. Each belt is equipped with unloading trolley, and the dust removal facilities include air extraction hood, air duct, adjusting gate, sealing belt and so on. The main equipment under the trough includes feeder,…
Blast furnace process automation is generally equipped with two levels of automation control system for the blast furnace: Level I is the basic automation system, Level II is the process computer system. The basic automation system consists of electrical transmission and control automation and process detection& control automation system, and its…
Process parameters of blast furnace engineering directly influence the safety of staff and plant operation. The measurement of process parameters mainly can help monitoring all systems running state well. Process control includes top pressure control, soft water closed circulation system expansion tank pressure control, combustion control of hot blast furnace…
Electrical system of blast furnace divides into High-voltage (HV) and Low-Voltage (LV) power supply and distribution,electrical transmission and control, process detection and control, basic automation. High-voltage power supply and distribution facilities The high-voltage power distribution of blast furnace is generally 10kV, and the total power supply of upper level is…
Blast furnace water system mainly divides into soft replenishment water, closed-circuit soft water , purified circulating water, straight water, slag treatment water, and blower station purified circulating water system (steam blower station is equipped with desalinated water supply and regeneration waste liquid drainage system), and in addition, the fire-fighting water,…
