Ndeupi mutsauko pakati zvidhinha zvinopesana nezvidhinha zvekuvharisa?

Basa guru rezvidhinha zvinopisa zvinopisa nderokuchengetedza kupisa uye kuderedza kupisa. Zvidhinha zvinopisa zvekupisa kazhinji hazvibati murazvo wakananga, nepo zvidhinha zvinoramba zvichingobata moto wacho. Refractory zvidhinha zvinonyanya kushandiswa kutsungirira kupisa kwemoto. Kazhinji yakakamurwa kuita mhando mbiri, dzinoti unshaped refractories uye shaped refractories. Unshaped refractory material: inonziwo inokandwa, iri musanganiswa wehupfu granule inoumbwa nemhando dzakasiyana siyana dzakaunganidzwa kana dzakaunganidzwa uye imwe kana anopfuura anosunga. Inofanirwa kusanganiswa neimwechete kana kupfuura zvinwiwa uye yakasanganiswa zvakaenzana panguva yekushandisa. Ane simba liquidity. Shaped refractory materials: anowanzo gadzira zvidhinha zvinoramba, chimiro chayo chine mitemo yakajairwa, uye inogona zvakare kugadziriswa kwenguva pfupi maererano nezvinodiwa pakuvaka nekucheka.

Misiyano mikuru pakati pezvidhinha zvinopisa zvekupisa uye zvidhinha zvinoramba ndezvinotevera:

1. Thermal insulation performance

Kupisa kwekupisa kwezvidhinha zvinopisa kunowanzo kuve 0.2-0.4 (avhareji tembiricha 350±25°C) w/mk, ukuwo kudziya kwezvidhinha zvinokatyamadza kuri pamusoro pe1.0 (avhareji tembiricha 350±25°C) w/mk, uye thermal insulation brick inogona kuwanikwa. Iko kupisa kwekushisa kwekushanda kweRefractory Brick kuri nani kupfuura iyo yezvidhinha zvinoramba.

2. Refractoriness

Iyo refractoriness yezvidhinha zvekuvharisa kazhinji iri pasi pe1400 madhigirii, nepo refractoriness yezvidhinha zvinoramba iri pamusoro pe1400 madhigirii.

3. Kuwandisa

Zvidhinha zvekuvharisa kazhinji zvireru zvehuremu zvekudzivirira, zvine density ye 0.8-1.0g/cm3 uye kuwanda kwezvidhinha zvinoramba kuri pamusoro pe2.0g/cm3.

Kazhinji, zvidhinha zvinoramba zvine simba remuchina, hupenyu hurefu hwesevhisi, kugadzikana kwekemikari yakanaka, hapana makemikari anopindirana nemidziyo uye yakanaka yakakwirira tembiricha kuramba. Iyo yakanyanya kupisa kupisa tembiricha inogona kusvika 1900 ℃. Iyo inonyanya kukodzera kune yakakwira uye yakaderera tembiricha shift furnaces, reformers, hydroconverters, desulfurization matangi uye methanizers mumakemikari fetiraiza zvidyarwa kuparadzira gasi uye mvura, uye kutsigira, kuvhara nekudzivirira zvinokonzeresa. Inogona zvakare kushandiswa mukupisa kuputika zvitofu uye kupisa kushandura midziyo muindasitiri yesimbi nesimbi.

Refractory zvidhinha zvine zvakanakira kusimba kwepamusoro, kusimba kwepamusoro, kusapfeka, kumira zvakanaka kwecorrosion, kuderera kwekuwedzera kwemafuta ekuwedzera, kugona kukuru kwekukuya, ruzha rwakaderera, hupenyu hurefu hwebasa, uye zvinhu zvisina kusvibisa. Iri svikiro rekukuya rakakodzera michina yakasiyana-siyana yekukuya.

Refractory zvidhinha zvakasiyana zvakanyanya kubva kune thermal insulation zvidhinha, uye kushandiswa kwavo nharaunda, chiyero uye basa zvakasiyana. Zvinhu zvakasiyana zvichashandiswa munzvimbo dzakasiyana. Pakusarudza zvinhu, isu tinofanirwa kusarudza kuti ndeipi refractory zvinhu zvinokodzera isu pachedu kushandisa zvinoenderana nemamiriro edu chaiwo.
