Titanium tube normalizing the purpose and characteristics
Tsingtek grade 1 titanium tube in Ac3 transformation point ( usually Ac3 +50 ℃). Organization of hot rolled steel S355 ferrite - pearlite purpose , normalizing process is to refine the organization , so that even the organization , improve the toughness of the steel.
Refinement of the original degree of organization and related organizations . For rolled steel can not be controlled , especially thick section steel, by normalizing the grain refinement can be achieved very good results. For thin section of steel , may not reach the normalized object refinement , in this case , the rolling process can be considered to control the rolling process , usually called " normalizing rolling " , zirconium plate organization and the hot-rolled microstructure and properties similar performance after normalizing .
Usually normalized Nb improve the tensile strength of steel , grade 2 titanium wire tube can prevent austenite grain growth , expansion of γ -phase region . In steels containing Si , this effect is particularly evident. Normalizing temperature between 900 ℃ and 1050 ℃, Nb content of 0.02% to 0.04%, enough to make the grain size reaches 10 . On the contrary , when the Si -containing steels contain Nb, normalizing temperature is 1000 ℃ , the grain size of 7 .
Nb carbonitrides and nitrides of Al , as in 1050 ℃ still be able to prevent austenite grain growth , this effect is particularly important , even in a non-uniform furnace temperature heat treatment furnace can be obtained fine ferrite body - pearlite .
A liquid crystal panel section of the module (LCM): panel process can be divided into three stages, first semiconductor processes preceding (array), that is, the transistor is a thin film layer on the glass substrate made, compared with the middle of the liquid crystal filling assembly process (cell), that is, the color filter layer of glass and glass film transistors, together, poured into a liquid crystal intermediate.
