The bottom 1800*8 ST3SP5 GOST 6533-78 is an integral part of machines and vessels working under pressure (the method of hot forging with heat treatment) and for filling (method planirovanie). PC Boiler produces the bottom 1800*8 steel ст3сп5 modern equipment company Sahinler. Basic dimensions elliptical head 1800*8 correspond to GOST 6533-78 "flanged elliptical Bottoms steel, for vessels, boilers and vehicles.
PC Boiler is the manufacturer of elliptical bottoms, 1800*8 steel ст3сп5 by the following methods:
Hot stamping bottoms 1800*8 ст3сп5 according to GOST 6533-78.
Cold planirovanie 1800*8 ст3сп5 according to GOST 6533-78.
Hot stamping elliptical bottoms with GOST 6533-78 1800*8 steel ст3сп5 takes place in the following way: before forming, the blank for the bottom 1800*8 ст3сп5 we heat and withstand a certain time in a furnace. Next, a heated billet bottoms 1800*8 is fed to stamping press preloaded with a die and a punch. Shaping takes place by hydraulic impact to the workpiece multi-ton pressure, then the obtained ellipsoidal head 1800*8 steel ст3сп5 cools the air.
Cold planirovanie elliptical bottoms with GOST 6533-78 1800*8 steel ст3сп5 is as follows: the workpiece in the cold state is supplied to the hydraulic press where the initial forming is required of the internal radius of the bottom. Next, the resulting billet we moved to planirovochnuju machine Sahinler. With the help of rollers edging machine is gradually shaping for a given program.
To impart the desired mechanical properties, the bottoms elliptic 1800*8 steel ст3сп5 produce their heat treatment. The need for thermal treatment in the manufacture is established by the requirements of GOST R 52630-2012.
