Based on analysis of the characteristic of water from the dust scrubbing system of the converter and the successful practice for treatment of that water in Honghe Iron & Steel Co. Ltd. ,the principle,method and process control(water quality control) criterion for chemical treatment of such water are discussed.
This paper deals with increasing the availability and automatic control level of 385m2 kelly filter further by utilizing PLC control technology, associating with the characteristic of PLC technology and the electrical interlocking property of 385 m2 kelly filter, under the condition of operation practice。
This article introduces the practice on high efficiency of CSP continuous casting in zhujiang steel,such as the casting speed、production rate、sequence rate、casting powder’s development on container steel and the LCR’s modification etc .
Establishing overturn machine theory model , boundary conditions and so on which are fit for practice ,. Comparing the result and the fact , analyzing the reason of destroy and finding the methods to solve the problem .
A chemical analysis has been posed for the determination of Si3N4,SiC,fSi,SiO2,Fe2O3,Al2O3in the Si3N4 bonded Sicproducts containing higher alumina content(0.5%-20% ). The practice has justified its accuracy and precision and reliability.
nalysis on the debign of the C 8513 ingot mould structure and practice in wisco show that the results of stress during using C 8513 die do not conform to practical effects,The average lifetime of the mould is 41 times,and the loss per ton of steel is approximately 30kg(not repaired),which is smaller than the loss of D 8413 ingot mould by about 30%and has a more distinct effect.
The principle and dynamics condition of RH vacuum refining decarburization are introduced,and the method of the fast and deep decarburization in production practice are discussed,inorder to attain Low carbon content steel.
Application of Random Process in Practice of Blending
Based on practice and theory of oxygen enriched blasting and coal injection applied to blast furnace, it is considered that this technology can keep the ferromauganese blast furnace in smooth operation ordinarily under the optimum theoretical combustion temperature in front of the tuyers.
Concerning about the problems in the practice of the first 3MVA highshaft hood submerged-arc furnace expanding to 6 MVA low shaft hood submerged-arcfurnace, the relative measures are taken. Good effect received after applied it to the second furnace capacity expand.
This paper discussed some problems affecting the quality of the continuous casting billets and appearing in the practice of the 4-strand 150**************X 150mm2 continuous caster at the 2nd Steelmaking Plant Luoyang Steel Works, and proposed some reasonable measures.
