Description
Применение в машиностроительной промышленности способов заварки дефектов в полых издели х в присутствии воды, заполн ющей внутренние полости, известно. Заполнение после сварки таких полостей золой, шлаком и другими малотеплопроводными веществами, в цел х осуществлени равномерного охлаждени деталей, в частности чугунных , также известно.The use in the engineering industry of methods for welding defects in hollow articles in the presence of water filling internal cavities is well known. After welding such cavities, filling with ashes, slag and other low-conductive substances, in order to realize uniform cooling of parts, in particular pig-iron, is also known.
Предлагаемый способ отличаетс от существующих применением Л.ЛЯ заполнени внутренних объемов издели песка до нагрева и сварки издели , с целью создани большего запаса тепла.The proposed method differs from the existing ones by using L.L.A. to fill the internal volumes of the sand product before heating and welding the product, in order to create a larger heat reserve.
Перед нагревом чугунна деталь, подлежаща заварке, плотно набиваетс сухим речным песком и отверсти закрываютс пробками из глины. После этого деталь нагреваетс вместе с песком до необходимой температуры и завариваетс автогеном. Остывание детали происходит на воздухе вместе с песком.Before the cast iron is heated, the part to be welded is tightly packed with dry river sand and the holes are closed with clay plugs. After that, the part is heated together with sand to the required temperature and brewed by autogen. Cooling of the parts occurs in the air with sand.
Предмет изобретени Subject invention
Способ газовой заварки дефектов в чугунных полых издели х с заполнением внутренних полостей теплопоглощающими веществами, отличающийс тем, что, в цел х создани значительного запаса тепла и равномерности охлаждени детали после заварки, заполнение детали малотеплопроводными веществами, например, сухим песком, производитс до подогрева и заварки детали.The method of gas welding of defects in cast iron hollow products with filling internal cavities with heat-absorbing substances, characterized in that, in order to create a significant heat reserve and uniform cooling of the part after welding, the part is filled with low-heat-conducting substances, such as dry sand, before heating and welding the details.
