Zvinofungidzirwa kuti kuburitswa kwepasirese kwezvinhu zvinoramba kwasvika 45 × 106t pagore, uye yakaramba ichikwira kumusoro gore negore.
Indasitiri yesimbi ichiri musika mukuru wezvinhu zvinoramba, zvichidya inenge 71% yegore refractory goho. Mumakore gumi nemashanu apfuura, kugadzirwa kwesimbi kwepasi rose kwakapetwa kaviri, kusvika 1,623 × 106t muna 2015, iyo inenge 50% inogadzirwa muChina. Mumakore mashoma anotevera, kukura kwesimende, ceramics uye zvimwe zvigadzirwa zvemamineral zvichaenderana nekukura uku, uye kuwedzera kwezvinhu zvinoramba zvichishandiswa mukugadzirwa kwesimbi uye zvisiri zvesimbi zvicherwa zvigadzirwa zvichawedzera kuchengetedza kukura kwemusika. Kune rimwe divi, kushandiswa kwezvinhu zvinoramba munzvimbo dzese kuri kuramba kuchidzikira. Kubva mukupera kwema1970, kushandiswa kwekabhoni kwave kutariswa. Zvidhinha zvisina kupiswa zvine kabhoni zvakashandiswa zvakanyanya musimbi uye simbi kugadzira midziyo kuderedza kudyiwa kwezvidziviriro. Panguva imwecheteyo, yakaderera simende Castables akatanga kutsiva akawanda asiri kabhoni refractory zvidhinha. Zvisina kuumbwa zvishongedzo, senge zvinokandwa uye jekiseni zvinhu, hazvisi chete kuvandudzwa kwezvinhu pachazvo, asiwo kuvandudzwa kwenzira yekuvaka. Kuenzaniswa neine isina kuumbwa refractory lining yechigadzirwa chakaumbwa, kuvakwa kunokurumidza uye kuderera kwemoto kunoderedzwa. Inogona kuderedza zvakanyanya mari.
Unshaped refractories account ye50% yemusika wepasirese, kunyanya tarisiro yekukura kwevanokanda uye preforms. MuJapan, segwara rekufamba kwepasirese, monolithic refractories yakatoverengera 70% yeiyo yakazara refractory yakabuda muna 2012, uye musika wavo wakaramba uchiwedzera.
