High-temperature industrial fields a lo thang chak tak avangin, metallurgical heat-resistant steel chu petrochemical, power, metallurgical leh industry dangtea hmanraw pawimawh tak tak siamna atana hmanraw duh ber a ni ta a, hei hi a high-temperature strength, oxidation resistance leh creep resistance tha tak a nih vang a ni. Mahse, heat quality of heat-resistant steel hian hmanrua service life leh safety a nghawng nghal vek a, chuvangin construction standards khauh taka zawm a pawimawh hle.
Material thlan leh enkawl dan tur .
Metallurgical heat siam-resistant steel siam hian a hmasa berah chuan material hian international emaw industry emaw standard, ASTM, ASME emaw GB/T emaw ang chi a tlin ngei ngei tur a ni. Common heat-resistant steel grades zingah hian 310s, 309s, GH3030, etc. Grade hrang hrang hi temperature hrang hrang leh corrosive environment hrang hrangah a tha hle. Spectral analysis, hardness testing leh non-destructive testing te chu material-in site a luh hmain a composition leh performance te chu standards a tlin theih nan a ngai a ni. Chu bakah, welding stress tihziaawmna tur leh crack awm loh nan welding hmain heat{-resistant steel chu preheated a ngai bawk.
Welding kalpui dan tur control .
Welding hi heat-resistant steel siamna atana core link a ni a, process parameters te chu khauh taka control a ngai a ni. Welding method hian manual arc welding, TIG welding emaw laser welding emaw a hmang tlangpui a, duhthlanna bik chu workpiece thickness leh structural requirements-ah a innghat a ni. Welding current, voltage leh speed te chu material property ang zela siamrem a ngai a, matching heat-resistant steel welding materials hman tur a ni. Multi-layer leh multi-pass welding a nih chuan interlayer temperature chu overheating leh grain coarsening awm loh nan a reasonable range chhunga control a ngai a ni. Welding zawhah chuan non-WELD (UT, RT ang chi) testing test a ngai a, chu chu quality a nih theih nan a ni.
Heat treatment leh inspection .
Heat-resistant steel hi a tlangpuiin construction hnuah heat treatment a ngai tlangpui a, solution treatment emaw stabilization treatment emaw pawh telin, residual stress tihbo nan leh microstructure performance tihchangtlun nan. Heat treatment temperature leh hun chuan overburning emaw underheating emaw a awm loh nan material specifications te chu khauh takin a zawm tur a ni. A tawp berah chuan macroscopic inspection, hardness test leh high-temperature tensile test te a awm a, chu chuan product chu design mamawh a tlin leh tlin loh a enfiah a ni.
Hriselna leh boruak humhalh .
Heat-resistant steel siam hian high-temperature operation a huam a, kangmei venna leh scald venna tur ruahmanna siam a ngai a, a tul anga mimal invenna hmanrua te pawh hman a ngai bawk. Chutih rual chuan, boruak humhalhna atana thil tulte phuhruk nan meikhu leh bawlhhlawh thilte welding chu uluk taka enkawl a ngai bawk.
Metallurgical heat-resistant steel-a construction standards mastering hian project quality a ti tha thei mai bakah equipment life a ti rei thei a, enterprise tan value sang zawk a siam thei bawk.
