FIELD: process engineering.
SUBSTANCE: invention relates to making of pipe insulation of mineral cotton. Proposed device comprises pipe insulation section solidification part including one or several moulds (31, 32), cylindrical on the side of inner surface. Note here that said solidification part comprises core (51, 52), each being fitted inside the every mould or designed to be fitted therein and withdrawn therefrom. Note here that first heaters are arranged on every mould (31, 32), at least over its inner surface. Second heaters heat pipe insulation sections placed in said moulds by microwave radiation. Note here that said second heaters are composed of generators (61, 62) to transmit microwave power to every mould via conducting modules (11, 12) and adapter elements (21, 22). Note here that said cores are made from material heating under effects of microwave radiation.
EFFECT: power savings, higher quality.
