Combined with the computerized control system of 14t/h boiler in Tianjin Iron & Steel Corporation, its working principle, the important control circuits and implementation methods for each control key are discussed.
As an example of 650 furnace in Anyang iron and steel corporation, the relationship among furnace structure, real operation and management and the energy saving effect of implementing the integrated technology are investigated.
Using the "x"shape immersed tap which can make the molten steel stir by itself, through the industry test of small square ingots(135mm×135mm and 165mm×165mm)of Q235,12MnCu and 16Mn in the first steelmaking works of A Steel & Iron Company ,the method is proved to be advantageous to improve the structure of a ingot.
Using the“x”shape invading water pipe made by writers which can make the molten steel stir by itself, by the industry test on small square ingots(135×135 and 165×165)of Q235,12MnCu and 16Mn in the first steel branch of A Steel & Iron Company, the method is proved advantageous to improve the form of a ingot.
Thirdly, after the thoroughly analysis on the problems of the present performance appraising in Xiangtan Steel & Iron Company, we, according to the requirements of BSC, redesign the performance appraising system from four aspects of financial index, client index, operation index and innovation index.
This paper simply explains the development course of light reduction technology for continuous casting slab and introduces the application situation of this technology in iron and steel companies at home and abroad.
For the 7 kg coke oven coke samples obtained from 10 single kinds of coal, sev- en skip coke samples and seven tuyere coke samples from seven iron and steel companies, their Micum drum strength, I-drum strength, microscopical strength, structural strength, tensile strength and optical strength are measured. Through measurement the inherent relations be- tween them are revealed.
Accompanied with the main petroleum companies and huge steel companies' merger and recombination, the continual cooperation between vessel companies or between vessel companies and cargo owners not only occurs but gets deeper, which has made the application of the contract of affreightment used more widely since the late 90s last century.
