(1) Processing technology manipulation
Manipulatio tecnologiae processionis prohibuit centrum administracionis ne attenuat et crescere parietem densitatem trans limitationes control.Q345B square pipe welding spatters knowledge of preventive measures and further controls the precision of Q345B square pipe wall thickness;
(2) Heating of pipe material
Temperatura medianda est, et cauda quadrata Q345B fertilis caligat temperaturam velocem auferentem et refrigendum.Quando auferas et refrigeris, perseverabis et perseverabis et manebis, et maximus auferens temperatura et fluctus temperatura non excessit 30 °C.
(三)Precisio mandrelli
The length and slenderness of Q345B square steel tube mandrel is relatively large, Q345B square tube-Q345B seamless square tube-Q345B square steel tube-Q345B cold drawn square tube-Shandong Dingyu Metal Material Co., Ltd. generally chooses the diameter of the first car and then gets rid of the mouth welding,Au elegit materia longa subito molantur ad formam.Precisio machinae exterioris mandrelli intra ±0 mm controtur, et simplicitas mandrelli non plus quam 5 mm est.When welding, Q345B square tube welding spatters preventive measures Knowledge Two-segment mandrel pierces a deep-processed pin to carry out precise positioning, Q345B square steel tube avoids "upper cold rolling"aut "lower cold rolling",Q345B square tube related specifications and models Smaller mandrels can be replaced by solid core blanks.Tabulae firmae et nubes solidae cum medio parietem densitate potest maxime reddere probabilitatem deformationis mandreli et possunt ultra improvire densitatem precision tubae quadratis Q345B
(5) relief roll
It's clear whether the confidence roll equipment can be timely, adjust t
