FIELD: metallurgy.
SUBSTANCE: stopper contains the housing, the connecting element for connection of gas pipeline and the gas channel with a total length L. Inside the gas channel the heat resisting material is placed the solid parts of which lay along the gas channel to the distance R, greater or equal 25% of the length L, and the gas channel is filled 10-90% by volume along R distance.
EFFECT: at gas flow for processing along the gas channel, the products of abrasion of lining are collected in the zone of heat resisting material that provides decrease of gas contamination.
