摘要
The process for manufacturing mineral wool by internal centrifuging is characterized in that the temperature of the mineral material in the fiberizing spinner dish is at least 1150° C. and in that the fiberizing spinner dish is made of a cobalt-based alloy comprising the following elements (in percentages by weight of the alloy):
Cr23 to 34%Feless than 3%Ni 6 to 12%Siless than 1%Ta 3 to 10%Mnless than 0.5%C0.2 to 1.2%Zrless than 0.1%W 0 to 8%,
the balance consisting of cobalt and inevitable impurities and the tantalum-to carbon molar ration being at least 0.3. Alloys particularly suitable for this process satisfy the above formula and do not contain tungsten. The alloys according to the invention can be used for other purposes in an oxidizing atmosphere at a temperature of at least 1100° C.
