Nanu la reng depektu na prone kareng valve casting?

1. Ing stomata

Iti metung yang malating cavity a mebuu keng gas na ing metal solidification process e ya makatakas kilub ning metal. Makinis ya ing kayang kilub a pader at atin yang gas, a maki matas a reflectivity king ultrasonic wave, dapot uling spherical ya o ellipsoid ya, metung yang point defect, a makaapektu king kayang reflection amplitude. Ing buak ning angin keng ingot mipatag ya keng metung a area defect kaybat nang me-forge o me-roll, na masanting akit kapamilatan ning ultrasonic inspection.

2. Retraction ampo loose hole

Potang ing casting o ingot melamig ya at me-solidify ya, ing volume dapat yang lumiit, at ing hollow defect e ya malyaring dagdagan ning liquid metal. Mayayaus lang shrinkage holes deng mangaragul ampong concentrated a vovities, at deng malati ampong makalat a void awsan dong loose. Uli ning batas ning thermal expansion ampo ing cold contraction, ing shrinkage hole siguradung atyu ya, pero atin yang miyayaliwang porma, sukad ampo posisyun kareng miyayaliwang paralan ning pamagprosesu, at maging yang depektu nung mipalapad ya keng casting o ingot body. nung e ne pututan ning ingot ing shrinkage hole at idala ne keng forging parts, maging yang residual shrinkage hole (residual shrinkage hole, residual shrinkage pipe).

3. Clip slag

Ing slag keng prosesu ning pamagtunaw o ing refractory keng katawan ning hurno mag-peel ya keng likidung metal, at miguguyud ya keng casting o steel ingot neng magbubusbus, gagawang slag clamp defect. Ing slag keraklan e ya magdili-dili, maralas king makapal a kabilian o makakalat king miyayaliwang kalalaman, kalupa ne ning volume defects dapot maralas atin yang metung a linearity.

4. Mixed

Deng reaksyun a produktu keng prosesu ning pamagtunaw (antimo ing oxide, sulfide, atbp.) -e-metallic a kayabe, o ing karagdagan a materyal da reng mapilan a sangkap kareng sangkap a metal e la lubus matunaw at manatili lang maging metal a kayabe, antimo reng matas a densidad, matas a melting point a sangkap-tungsten, molybdenum, atbp.

5. Paraphrase

Ing pamikawani keng casting o ingot keraklan mangabaldugan yang pamikawani da reng sangkap a mebuu keng e pantas a pamikalat da reng sangkap keng prosesu ning pamagtunaw o ing prosesu ning pamagtunaw ning metal. Ing mechanical properties ning area a maki segregation miyayaliwa ya kareng mechanical properties ning mabilug a metal matrix, at ing pamiyaliwa lampas keng allowable standard range maging yang defect.

6. Casting cracks

Ing crack keng casting keraklan sangkan ne ning shrinkage stress ning metal cooling solidification lalagpus ya keng katataulian a sikanan ning materyales, makasuglung ya keng porma ning casting design ampo ing prosesu ning casting, ampo makasuglung ya naman keng cracking sensitivity da reng mapilan a impurities keng metal materials (antimo ing matas a sulfur content, cold brittleness, highphorus contents, atbp.). Ing spindle, atin ya namang bitag ing shaft crystal, at keng tutuking billet forging, manatili ya keng forging bilang internal crack ning forging.

Bukud pa, ing Tianjin Tanggu Water Seal Valve Co., Ltd. metung yang technologically advanced elastic seat valve a susuporta kareng negosyu, deng produktu ilapin dengrubber seat wafer butterfly valve, lug butterfly valve, double flange concentric butterfly valve, double flangeeccentric butterfly valve, balance valve,wafer dual plate check valve, Y-Strainer at aliwa pa.
