Description

Изоб1рете,ние лредназначено дл труб большой длины, где абсолютна величина усадки футеровки достигает значительных р аз .М еров.The invention is designed for long pipe lengths, where the absolute amount of shrinkage of the lining reaches significant times. M erov.
Известна форма дл изготовлени ка.менных труб в обечай,ках, содержаща цилинд .рический корпус с торцовыми плоскими крышками.A well-known form for the manufacture of casing tube pipes in the shell, comprising a cylindrical body with face flat caps.
Цель изобретени - компенсаци линей .ной усадки каменной трубы по длине обечайки .The purpose of the invention is to compensate for the linear shrinkage of the stone pipe along the length of the shell.
Это достигаетс тем, что торцовые крышки выполнены в виде цилиндрических чаш.This is achieved in that the end caps are made in the form of cylindrical bowls.
На чертеже изображена частично описываема форма дл изготовлени каменных труб в обечайках.The drawing shows a partially described mold for making stone pipes in the shell.
Форма имеет цилиндрический корпус / и торцовые крышки 2. Последние выполнены в виде цилиндрических чаш, внутренний диаметр которых соответствует внутреннему диаметру обечайки, а глубина b выбираетс следующим образом.The shape has a cylindrical body (and end caps) 2. The latter are made in the form of cylindrical bowls, the inner diameter of which corresponds to the inner diameter of the shell, and the depth b is chosen as follows.
Если труба 3 фиксируетс по середине, то .при усадке она ст гиваетс от обоих торцов к серединеIf the pipe 3 is fixed in the middle, then during shrinkage it is pulled from both ends to the middle.
b .(1)b. (1)
Если труба фиксируетс на одном из торцов , то три усадке о.на ст гиваетс к этому торцуIf the pipe is fixed on one of the ends, then three shrinkage points on the end of this pipe.
b EL,(2)b EL, (2)
где L-длина цилиндрического корпуса;where L is the length of the cylindrical body;
Е- коэффициент линейной усадки закристаллизованной футеровки.E is the coefficient of linear shrinkage of the crystallized lining.
.При заливке обечайки на центробежной машине, например, через центральное отверстие 4 крышки, расплав заполн ет крышку. В процессе охлаждени камнелитна футеровка дает усадку, равную EL, в результате чего она принимает длину L, соответствующую размеру формы (обечайки).When melting the shell on a centrifugal machine, for example, through the central opening 4 of the lid, the melt fills the lid. In the process of cooling, the stone lining shrinks to EL, with the result that it assumes a length L corresponding to the size of the mold (shell).
Предмет изобретени Subject invention
Фор.ма дл изготовлени каменных труб в обечайках, содержаща цилиндрический корпус с торцовыдш крышками, отличающа с тем, что, с целью компенсации линейной усадки каменной трубы по длипе обечайки, торцовые крышки вьрполнены в виде цилиндрических чаш.A mold for the manufacture of stone pipes in the sides, containing a cylindrical body with end caps, characterized in that, in order to compensate for the linear shrinkage of the stone pipe along the length of the shell, the end caps are made in the form of cylindrical bowls.
