Tunlai industry-in high-temperature material performance a mamawhna a tihchangtlun zel avangin, metallurgical heat-resistant steel chu energy, chemical industry, aerospace, etc. field-a thil pawimawh tak a lo ni ta a, a high-temperature strength, oxidation resistance leh creep resistance te nen. He article hian metallurgical heat-resistant steel leh a hmanna hlutna chu technical lam atanga thlirin a bulpui ber a ni.
Metallurgical heat-resistant steel-a hlawkna bulpui ber chu a high-temperature stability-ah a awm a ni. Chromium, nickel, leh molybdenum ang chi alloying elements te dah belhin, heat-resistant steel hian temperature sang takah dense oxide film a siam thei a, chu chuan matrix chu a oxidation belh zel tur a veng thei a ni. Entirnan, heat-resistant steel chromium content 12% aia tam nei chuan 800℃aia sang environment-ah long-term stability a vawng thei a, nickel-based heat-resistant steel chuan temperature sang zawkah structural integrity a vawng reng thei bawk. He feature hian high-temperature components gas turbine blade leh boiler pipe te ah te hman a ni nasa hle.
Mechanical property lamah chuan metallurgical heat-resistant steel hian microalloying leh heat treatment process optimization hmangin a creep resistance chu nasa takin a ti tha a ni. Vanadium leh niobium ang chi microalloying elements te dah belh hian grains te chu a tithianghlim thei a, grain boundary sliding chu temperature sang takah a tikhawlo thei a, chu chuan material deformation a tikhawtlai thei a ni. Long-High-End heat thenkhat chakna chu 600 degree-a resistant steel products 100mpa aia tam a thleng thei a, extreme working conditions mamawh a phuhruk thei a ni.
Process adaptability hi metallurgical heat-resistant steel-a thil langsar dang a ni bawk. Tunlai smelting technology hrang hrang vacuum induction melting (VIM) leh electroslag remelting (ESR) te hman hian material chhunga bawlhhlawh awm zat chu nasa takin a ti tlem a, a thianghlimna pawh a tichangtlung hle. Chutih rual chuan, controlled rolling and controlled cooling (TMCP) ang chi advanced process te chuan steel chu toughness tha tak a nei thei a, chutih rualin strength sang tak a vawng reng a, traditional heat brittleness sang tak pain point a solve thei-resistant steel a ni.
Environment humhalh leh economy pawh hi heat-resistant steel technology hmasawnna kawng pawimawh tak a ni. Composition design optimize-na hmangin, heat siam tharna-resistant steel hian rare metals awm zat a tihtlem bakah performance a ti tlem a, performance a tichiang bawk. Chu bakah, heat-resistant steel products thenkhat chu recycle leh hman nawn theih a ni a, hei hi industrial trend of sustainable development nen a inmil a ni.
Nakin lawkah chuan material technology thar a lo chhuah takah chuan metallurgical heat-resistant steel hian temperature sang zawk leh hnathawh dan buaithlak zawkah theihna a nei sang zawk ang a, industrial equipment te chu efficiency sang leh dam rei lam hawia hmasawn turin a tichak zel ang.
