1. Способ подготовки заготовок (гильз) из легированных марок стали и сплавов к пилигримовой прокатке труб, содержащей нагрев заготовок (гильз) и изготовленных из недорогих углеродистых марок стали патрубков (подкладных колец), наружный диаметр которых больше диаметра гильз, отличающийся тем, что патрубки имеют цилиндрический и конический участки, размеры которых определяются из выражений
Lк = 0,6 - 0,8 Dг
Lц. у. = 0,35 - 0,4 Dг
Lк. у. = 0,25 - 0,4 Dг
Dц. у. = 1,15 - 1,3 Dг
Dк. у. = 1,0 - 1,1 Dг,
где Dг - диаметр гильзы, мм;
Lк - общая длина углеродистого патрубка, мм;
Lц. у. - длина цилиндрического участка патрубка, мм;
Lк. у. - длина конического участка патрубка, мм;

The method of preparation of billets (sleeves) of alloyed steel grades and alloys for pilgrim rolling of pipes containing heating of the billets (sleeves) and made of inexpensive carbon steel grades of pipes (backing rings), the outer diameter of which is larger than the diameter of the sleeves, characterized in that the pipes have cylindrical and conical sections, the sizes of which are determined from the expressions
Lк = 0.6 - 0.8 Dg
Lts. at. = 0.35 - 0.4 Dg
Lk. at. = 0.25 - 0.4 Dg
Dc at. = 1.15 - 1.3 Dg
Dk. at. = 1.0 - 1.1 Dg,
where Dg is the diameter of the sleeve, mm;
Lк - the total length of the carbon pipe, mm;
Lts. at. - the length of the cylindrical section of the pipe, mm;
Lk. at. - the length of the conical section of the pipe, mm;
Dc at. - the diameter of the cylindrical section of the pipe, mm;
Dk. at. - the smallest diameter of the conical section of the pipe, mm 2. Способ по п. 1, отличающийся тем, что с увеличением диаметра цилиндрического участка патрубка длина конического участка возрастает с 0,25 до 0,4 Dг. 2. The method according to p. 1, characterized in that with an increase in the diameter of the cylindrical section of the pipe, the length of the conical section increases from 0.25 to 0.4 Dg. 3. Способ по п. 1, отличающийся тем, что конический участок патрубка меньшим основанием конуса прилегает к торцу гильзы. 3. The method according to p. 1, characterized in that the conical section of the pipe with a smaller base of the cone is adjacent to the end face of the sleeve.
