Fireproof<\/strong> describes the property of a ceramic material to withstand high temperatures without softening. Under German standard DIN 51060<\/strong>, the term is defined via the Seger cone fall point: the softening point of a standardised test piece (Seger cone) under defined heating conditions.<\/p>\n

Classification under DIN 51060<\/h2>\n

DIN 51060 classifies refractory ceramic raw materials and products into three levels by their measured Seger cone fall point:<\/p>\n\n\n\n\n\n\n\n
Level<\/th>\nSeger cone fall point<\/th>\n<\/tr>\n<\/thead>\n
Heat-resistant<\/td>\nup to 1,500 \u00b0C[2]<\/a><\/sup><\/td>\n<\/tr>\n
Fireproof<\/td>\n1,500 \u00b0C to 1,800 \u00b0C[2]<\/a><\/sup>[3]<\/a><\/sup><\/td>\n<\/tr>\n
Highly fireproof<\/td>\nabove 1,800 \u00b0C[2]<\/a><\/sup>[3]<\/a><\/sup><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

A material is therefore considered fireproof once its Seger cone fall point reaches at least 1,500 \u00b0C.[3]<\/a><\/sup><\/p>\n

Distinction from lining<\/h2>\n

Fireproof is a material property, not a component name. Lining<\/a> is the physical refractory brickwork of a melting or holding furnace, while furnace lining<\/a> is the general term for a furnace’s refractory lining as a whole. A material can be fireproof without being installed as a lining at all, for example as a brick or raw mix in storage.<\/p>\n
