Description
Способы изготовлени стекл нных трубок непрерывной подачей стекломассы через формующий полый мундштук с вдуванием внутрь получаемой трубки воздуха через тот же мундштук известны. Полученные таким образом трубки затемотжигаютс дл сн ти внутренних напр жений , получающихс в результате более сильного охлаждени трубок снаружи, чем изнутри.Methods for making glass tubes by continuously supplying glass mass through a forming hollow die with air blown into the resulting tube through the same die are known. The tubes thus obtained are then ignited to relieve internal stresses resulting from a greater cooling of the tubes from the outside than from the inside.
С огласно насто щему изобретению , к воздуху подмешивают распыленную воду или вод ной пар или полностью замен ют воздух вод д ным паром, т. е. вместо воздуха примен ют агент с более высокими теплоемкостью и теплопроводностью . В результате этого улучшаютс услови охлаждени трубки изнутри и они охлаждаютс с одинаковой скоростью как снаружи.According to the present invention, sprayed water or water vapor is mixed with air, or the air is completely replaced with water vapor, i.e. an agent with higher heat capacity and thermal conductivity is used instead of air. As a result, the conditions for cooling the tube from the inside are improved and they are cooled at the same rate as the outside.
так и изнутри, чем устран етс основна причина по влени в стенках больших внутренних напр жений , благодар чему производство избавл етс от необходимости дополнительной операции отжига со специальной целью сн ти этих опасных дл прочности издели больших внутренних папр жени.and from the inside, which eliminates the main reason for the occurrence of large internal stresses in the walls, due to which the production eliminates the need for an additional annealing operation with the special purpose of removing these products of large internal strengths that are dangerous to strength.
Предмет изобретени Subject invention
Способ изготовлени стекл нных трубок непрерывной подачей стекломассы через мундштук, с вдуванием внутрь трубки воздуха, от л ичающийс тем, что, с целью исключени последующего отжига трубок, к воздуху подмешивают распыленную воду или вод ной пар или полностью замен ют воздух вод ным паром.A method of making glass tubes by continuously supplying glass mass through a mouthpiece with air blown into the tube, due to the fact that in order to avoid subsequent annealing of the tubes, sprayed water or water vapor is mixed with the air or completely replaced with water vapor.
