Weight control runs through the entire life cycle of civil aircraft from design, manufacturing to operation. Though the pacing factor of aircraft＇s weight majorly stays in the link of design, in the view of the experience of domestic and foreign manufacturers, it still has optimization in the stage of aircraft mass production. This article generalizes […]
It is concluded the measures in operation practice of lowering charge level in 3 200 m3 blast furnace4# of Tang Steel： adopting empty charge line to recover gas,determining charge level with multi ways,atomization pouring water,strictly controlling top temperature within 250 to 300,reasonably arranging slag tapping and blast furnace tapping. With reasonable control for various operation […]
Most of the steel grades used for gear of high – end cars have to be controlled in its aluminum and nitrogen content to guarantee its grain size homogeneous and service characters steady. In these steels, nitrogen is generally added in by feeding nitralloy wire after vacuum treatment, but thus it could not be avoided […]
Because of the restrictions of social environment,laws and regulations,cultural customs,climate condition,social reliance and other factors, HSE management system localization is the bottleneck of overseas EPC project management. Taking the gas compressor station of China-Uzbekistan Gas Pipeline project for example, this paper analyzes the characteristics of HSE management system localization of EPC project,and expounds the practical […]
Two 2 500 m~3 blast furnace of Chong Steel began to control output capacity in the middle ten days of Oct,2015,the daily output per blast furnace reduced from 5 500 to 4 000 ~ 4 500 tons. The production was further limited in the end of Jan,2016,the daily output to 3 000 ~ 3 300 […]
In view of No. 2 continuous caster small billet mold assembly problems in No. 2 steel making plant of Anyang Steel,based on the actual production,measuring and monitoring taper change during assembly process is adopted to enhance the precision of maintenance and installation of the mould,thus reduces the bonding steel leakage accident,ensures continuous casting production smoothly.
The mechanism of consumption of graphite electrode in LF furnace is introduced. With measures：reformation in automatic adjust of electrode moving up or dow n,LF furnace hot slag circular utilization,LF furnace water- cooling cover structure reformation,applying electrode antioxidant paint,the consumption of electrode reduced from 0. 35 to 0. 25 kg per ton of steel,good effect got.
With the progress and development of science and technology, informatization permeates into all kinds of industries, and real estate enterprises should also carry out informatization construction. This paper analyzes the necessity of the real estate management informatization construction, discusses the problems existing in real estate management informatization construction, and puts forward the corresponding practice strategies, […]
In recent years, military and local has pushed forward the innovation of policy mechanism revolving around the fundamental duty which is training high-quality military personnel of a new type. integrated military and civilian talents cultivation is beginning to take effect. However, there are certain problems. For the situation of integrated military and civilian talents cultivation, […]
By a series of technical measures such as protecting furnace lining with titanium ore, appropriately increasing temperature in furnace, controlling air distribution, improving thermal conductivity and so on, the temperature of hearth and bottom of blast furnace decreases, the blast furnace condition is stable and good economical benefit is obtained.
