In this paper,the features and process of TRT(Top Gas Pressure Recovery Turbine) are described. An analysis of TRT control process and the trend in development is meade,concerning:using single-loop PID to control the speed-up of TRT;
论述了高炉煤气余压回收透平装置TRT(Top Gas Pressure Recovery Turbine)的工作特点和工艺流程,针对TRT控制工艺及其发展方向进行了分析,采用单回路PID控制TRT升速;
During the design of Angang's primary material field,programmable controller S7-300 was used to make unloading facilities and mineral facilities realizing automatic control,it was used to realize the chain controlling of belt conveyer that take the tilting mechanism as the core machine at the same time,and it was used to realize the experience of PID regulation and automatical burden in blow tank.
Experiments prove that 20%～50% of detitanizing efficiency can be achieved by 10～30kg/t of steel rolled iron scale used as desiliconizing agent and spreading method adopted in iron runner at the same time to desiliconize.
A comparative smooth and compact lead deposit with about 92% current efficiency can be achieved on stainless steel and lead cathode under the conditions of a current density of 100A/m2,temperature 55℃,pb2+ 30g/L and HCl 6g/L. The cathode lead product can be directly used for ingot casting.
Aiming at how to build the standard parts library of powder metallurgy moulds quickly, based on development tool of VC++6.0 and SQLserver2000, and using technologies of parametric modeling 、UG/OPEN API and ADO(ActiveX Data Object) ,which can improve the reusability of programs a method is introduced.
Based on the production of traditional sub-critical blade steel, Ben-Steel developed a system new products of Ultra ultra critical blade, adopt 50t electric arc furnace smelting→LF refining→casting 3t electrode→electroslag remelting→holding→annealing→800/650x4 rolling mill→K11C77Eф200 round steel, be nicely able to the mark of user requirements.
And the simulation was based on the data of practical industrial product process. The input and allocation of the electrical power in the melting period was optimized by Genetic Algorithm based on some steel.
