2021 1 Peb lub hlis twg ntawm Tuam Tshoj txoj kev lag luam refractories khiav lag luam
Ib qho tseem ceeb yog qhov nce me ntsis ntawm cov zis.
Raws li kev txheeb cais los ntawm Tuam TshojRefractoryKev lag luam Association, lub teb chaws refractory ntau lawm mus txog 6.344 lab tons, uas qhia ib tug 1.09% nce. Ntawm cov no, cov khoom lag luam compact-zoo li cov khoom lag luam suav txog 3.5025 lab tons, kos npe nce 1.07%. Thaum tshav kub kub rwb thaiv tsev refractory khoom muaj li 206,400 tons, nrog rau kev loj hlob ntawm 4.29%. Amorphous refractory khoom mus txog 2,635,100 tons, muaj kev nce siab ntawm 0.88%.
Lwm qhov tseem ceeb yog qhov txuas ntxiv rov qab los ntawm kev lag luam kev ntseeg siab.
Raws li cov ntaub ntawv los ntawm Tuam Tshoj Lub Tuam Txhab Ua Haujlwm Zoo Tshaj Plaws, cov khoom siv raw khoom tus nqi ntsuas yog 181.91 nyob rau lub Plaub Hlis 2021, sawv cev nce 1.5% txhua hli thiab nce 10.46% xyoo-rau-xyoo. Cov nqi ntawm qee cov khoom siv refractory kuj tau pom tias muaj kev nce ntxiv hauv ib xyoos. Qee cov tuam txhab lag luam muaj txiaj ntsig tau ruaj ntseg cov ntawv cog lus thiab tau pom tag nrho cov haujlwm tsim khoom, uas tau tsav los ntawm kev xav tau los ntawm kev lag luam hauv qab.
Tsis tas li ntawd, tus nqi ntawm cov khoom siv refractory tau nyob ruaj khov lossis tau nce ntxiv.
Taug qab cov txheeb cais los ntawm Tuam Tshoj Refractory Industry Association thiab Refractory Window Network qhia tias nyob rau hauv thawj peb lub hlis twg, tus nqi ntawm Shanxi bauxite clinker tseem siab thiab ruaj khov. Lub Hoobkas nqi (tsis suav se) ntawm Xiaoyi 85 hlau ncej kiln bauxite clinker yog 1950 yuan / tuj. Lub khw muag khoom xim av corundum kuj tau ntsib qee tus nqi nce, nrog rau cov nqi tseem ceeb ntawm lub Hoobkas (suav nrog se) txij li 4600 txog 4700 yuan / tuj. Tus nqi ntawm dawb corundum nyob rau hauv cheeb tsam Henan tau nyob ruaj khov, thaum tus nqi ntawm sintered corundum tau kuj tsis muaj zog.
Nyob rau lub Peb Hlis, lub Hoobkas nqi (nrog rau cov se) ntawm cov fused magnesia zoo tib yam (MgO Ntau dua lossis sib npaug li 95.5%, thaiv) hauv Liaoning yog 3000 yuan / tuj. Tus nqi tseem ceeb ntawm cov hlau nplaum hnyav heev (MgO Ntau dua lossis sib npaug li 90%, thaiv) hauv Liaoning yog 1550 yuan / ton, nruab nrab qib magnesia (MgO Ntau dua lossis sib npaug rau 94.5%, thaiv) yog 2700 yuan / tuj, thiab high-purity magnesia (MgO Ntau dua lossis sib npaug rau 96.5%, thaiv) raug nqi ntawm 3300 yuan / tuj. Thaum lub Plaub Hlis, tus nqi ntawm qhov hnyav-hlwb magnesia hauv Liaoning tau nce 50 txog 100 yuan piv rau qhov kawg ntawm lub hli dhau los. Tus nqi ntawm nruab nrab qib magnesia nce 100 yuan, thiab tus nqi ntawm high-purity magnesia nce li ntawm 100 yuan.
Plaub, tus nqi ntawm cov khoom refractory yog qhov ruaj khov los yog nce.
Raws li kev txheeb cais ntawm Tuam Tshoj Refractory Industry Association thiab lub qhov rais network ntawm cov ntaub ntawv resistant, nyob rau hauv thawj peb lub hlis twg, lub Hoobkas nqi ntawm magnesia carbon cib (Mt-14A) suav nrog se yog 5500 yuan / tuj; Tus nqi ntawm lub Hoobkas tseem ceeb ntawm qhov zoo tib yam magnesia-calcium cib suav nrog se yog 3500 yuan / tuj; ncaj qha ua ke magnesia-chrome cib Hoobkas nqi suav nrog se 4300 yuan / tuj; Henan siab aluminium cib (LZ-75) Hoobkas nqi suav nrog se 3500 yuan/ton. Tus nqi tag nrho ntawm cov khoom siv refractory nyob rau hauv thawj peb lub hlis twg tau nce ntau dua piv rau xyoo dhau los.
Thib tsib, ntshuam thiab xa tawm ntawm cov khoom tseem ceeb refractory tau nce xyoo-rau-xyoo.
Raws li kev lis kev cai txheeb cais, txij lub Ib Hlis mus txog Lub Peb Hlis, tag nrho cov khoom lag luam ntshuam thiab xa tawm ntawm cov khoom siv raw khoom hauv lub teb chaws yog 937 lab US las, nce ntawm 16.46% nyob rau tib lub sijhawm xyoo tas los. Tag nrho cov khoom xa tawm ntawm refractory raw khoom hauv lub tebchaws yog 1.5901 lab tons, sawv cev nce 10.40%. Ntawm lawv, kev xa tawm ntim ntawm cov khoom siv raw khoom yog 1.1687 lab tons, sawv cev nce 7.76%. Kev xa tawm ntim ntawm cov khoom lag luam refractory yog 421,400 tons, qhia txog 18.46% nce. Nyob rau hauv cov nqe lus ntawm export nqi, lub export ntim ntawm sintered magnesia thiab lub teeb-kub magnesia poob los ntawm 1.76% thiab 24.42%, feem, tab sis tus nqi export kuj ruaj khov. Lub ntim export ntawm fireclay, fused magnesia, thiab dawb corundum tau nce ntau, thaum tus nqi nruab nrab export tau nce me ntsis. Kev xa tawm ntim ntawm cov khoom alkaline tau nce 25.48%, thaum tus nqi nruab nrab xa tawm poob los ntawm 7.63%. Kev xa tawm ntim ntawm aluminium-silicon khoom tau nce 7.01% piv rau xyoo dhau los, thiab tus nqi nruab nrab xa tawm tau nce 8.67%. Tsis tas li ntawd, cov khoom xa tawm ntawm lwm cov khoom lag luam refractory tau nce 12.90% xyoo-rau-xyoo, nrog rau qhov nruab nrab xa tawm tus nqi nce 10.59%.
Thib rau, qhov cuam tshuam ntawm kev nce nqi raw khoom pib tshwm sim.
Hauv thawj peb lub hlis twg, vim qhov nce ntawm cov khoom siv raw khoom los ntawm lub quarter thib plaub ntawm xyoo tas los, kev nce siab ntawm tus nqi ntawm cov khoom siv refractory tau nce siab, thiab lub Hoobkas nqi ntawm cov khoom refractory nyob rau hauv thawj peb lub hlis twg tau nce mus rau ib tug. qee qhov, thiab tus nqi nce ntawm qee cov khoom tau txais los ntawm cov neeg siv khoom hauv kev lag luam hauv qab, thiab cov txiaj ntsig ntawm kev nce nqi raw khoom tau pib tshwm sim. Txawm li cas los xij, thaum kawg ntawm peb lub hlis twg, cov nqi ntawm qee yam khoom siv refractory tseem nyob rau hauv tus nqi tseem ceeb, thiab cov nyhuv kis tau tus mob tseem tsis tau paub.
