Klasifikasyon nan materyèl refractory

Gen anpil kalite materyèl REFRACTORY, ak metòd klasifikasyon aktyèl materyèl REFRACTORY yo apeprè jan sa a.

1, dapre refractories yo ka divize intoOrdinary refractories: refractories ki pi gran pase 1580 degre ~ 1770 degre High-grade refractories: refractories ki gen plis pase 1770 degre ~ 2000 degre .Refractories klas siplemantè: refractories ki pi gran pase 2000 degre ~ 3000 degre. refractories ki gen plis pase 3000 degre.

2, selon manifakti processAccording pwosesis manifakti a ka separe an wòch natirèl, piki labou, plastik par, semi-sèk par, sèk près par, ramming, fusion ak Association pwodwi sa yo.

3, according to chemical composition of a mineral can be divided into(1) siliceous productsSilica brick Si02>93% of the products, quartz glass Si02>99% of the fused products.(2) aluminum silicate productsSilicic acid Si02>65%, AI20s between 15~30%.Clay brick AI203 is between 30 and 48%.High aluminum brick AI203>48% of the products.(3) magnesium productsMagnesia brick: Mg0>85%, magnesia chrome brick Mg055~80% (Cr20:10~30%) products. Chrome magnesia brick: Mg025~55% combined with more chromite products; Magnesia-aluminum brick: magnesia-aluminum cuspite (Mg0-A1203) combined with magnesia-aluminum brick; Mg0·Si02) brick, Mg035~55%.Magnesium olivine (2Dolomite products: products with Ca0>40%, Mg0>35%.(4) Chrome brickCr20330%(5) carbonaceous productsCarbon brik: pwodwi ak kontni kabòn nan 70 ~ 90%Pwodwi grafit: pwodwi ki gen plis pase 30% graphite.Silisyòm carbure pwodwi: ak Sic kòm matyè premyè, fireclay oswa lòt inòganik pwodwi konbine.(6) espesyal refractoriesHigh tanperati seramik materyèl: cermet materyèl.

4 Divize pa fòm ak gwosè Dapre fòm ak gwosè ka divize an: estanda, jeneral, diferan, espesyal brik, anplis, refractories dapre metòd tire, selon itilize, selon karakteristik konstriksyon, gen kèk lòt klasifikasyon.
