Class Rotating Cylinder Generation And The Shape Of Internal Layer Of Blast Furnace Crucible Is Eroded Of The Display System

It is one importance research subject that the blast furnace has longevity in our country ironmelting.At present,the one of deciding longevity' restrictive key link is blast furnace hearth,it is realize blast furnace macrobian necessity instrument that monitoring hearth.It is blast furnace man expectant that on-line monitoring erode shape of the blast furnace hearth.This topic is precisely based on the reality to extend the life of blast furnace,To judg the erosion of blast furnace hearth.After making use of computer technology go to dispose the data which gathers,The erosion pattern is drawn.During the production it can direct the worker how to stick up for blast furnace,It also can presume the longevity of blast furnace.Made use of blast furnace utmostly,thereby create more profit.So,this topic possess very great value,If this topic research results will be used for modern expert systems of the blast furnace,it will create huge economic benefit for enterprise.In order to show precisly shape of hearth,must be familiar with the formation of free curves and surfaces.Basic idea is that dot forming line,line forming face,Has the separate data point to self-examine the free surface by calculating—class rotating cylinder.The computational process is as follows:On the known data points on the axis of the cross-section carry accurate calculation to the free surface,using computer-aided geometric parameters of the three samples of the curve on the knowledge data processing,obtains the smooth curve.Then interpolation calculated on any axis cross-section of the curve.Using the parameter pair of three spline surface's knowledge calculated on the free surface of the data points,and using computer graphics knowledge to draw out class rotating cylinder.This time produces the surface is the mesh surface.In order to make smooth surfaces,Through the use of the OpenGL graphics development tools surface rendering,obtains the smooth free surface.Obtains the application procedure the above process after translation processing.The platform of produceing this application is procedure development tools C++ Builder 6.0.It is a visualization of the design process,enabling the development of the application intuitive and easy to use.At last,the procedure is detected with MATLAB,judging drawing veracity.Will cylinder blast furnace shaft cross-section of data into the process to get the shaft cross-section of the erosion on the curve.Finally,obtain the lining of cylinder blast furnace erosion appearance.In order to more clearly show erosion appearance,May carry on to cut the furnace.Finally take the Baotou Steel Factory 2 2250m3 blast furnaces as the example,draws up its the lining of cylinder blast furnace erosion appearance.The procedure from this topic research has the versatility.It can draw class rotating cylinder fastly.It will be used for the shape of internal layer of blast furnace crucible is eroded of the display system,Its practicability is confirmed,and is making virtual tool for further research.
