1. Uncoiler/Uncoiling machine
Decoiling Machine for High Frequency Steel Pipe Welded Mill
Product description
Uncoiling machine is the main supplementary equipment in the welded pipe production line, it is used to support the steel strip and supply raw material for production, thus to assure the continuously production of the whole production line, brake style is controlled by whole linkage control, ensuring that the steel strip won't fall off during the production.
 
This machine consists of pedestal, double cones which can be contracted and expanded, rotary brace, pneumatic brake and electric control system. One of the cones is on-line, the other one is in preparative position. It can be circumrotated 180o

3. Vertical/Horizontal Accumulator
Decoiling Machine for High Frequency Steel Pipe Welded Mill
Product description
The accumulator is the main supplementary equipment in the high frequency welded pipe and cold rolling production line. It stores certain amount of steel strips and leaves more time for the shearing and butt welder to shear and weld the ends of the strips. Thus ensures the continuous production process.

4. Forming and sizing mill
Decoiling Machine for High Frequency Steel Pipe Welded Mill
Product description
Forming and sizing mill is the main equipment in the welded pipe production line. This line can continuously process certain specification length of steel strips into pipe barrel and weld it into pipe. It can not only produce round pipe but also can produce deformed pipe. This line utilizes roll forming principle to produce certain specification of steel pipes. That is feeding the machine with steel strip of a certain specification, then use forming roll to crimp the steel strip into pipe-blank. After high frequency induction-heating, cooling, sizing and straightness correcting then you can get the steel pipe of required specification.

Gravity Die Casting

Aluminum Gravity Casting always use the permanent moulding with the liquid aluminum pouring into the cavity by ladles or vessel.Most of None ferrous metal could be produced by this gravity casting process including aluminum alloy,zinc,Magnesium,copper alloy,brass.

The gravity casting process as below:

1.Heating the moulding

2.Spraying coat agent in cavity

3.Pouring the liquid metal into die

4.Aparting the moulding after cooling

5.Triming the casting parts
