Forging Closure

1.Save the materials 2.Increase of efficiency 3.Good quality

For the past many years, we commit ourselves to the study of open type stamp forging, and specialize in small, medium and large scaled rolling ring connectors and abnormal rolling ring connectors with a superior quality. Forging manufacture occupies an area of 92000m2, with 162 staff, including 39 technicians. Our mission is to satisfy all requirements and expectations of our customers, and to provide products with added value.

Objective

To satisfy the specific market demand

To reduce the supply time and to save cost for our customers

Strong Points

Save the materials

After the roller compaction, the ring parts have some excellences of high precision and few remain and save of up to 8%25% of the raw materials comparing with the F-class standard of flat die forging.

Proprietary technology and top level roller compaction equipment enable us to produce ring parts of various sections and shapes. These ring parts are symmetrical when rotating. It is because of the centered symmetrical feature that enables us to abnormal rolling to various kind of work piece, and to reduce the machine processing margin down to the minimum, so as to achieve similar shape as the final shape.

Increase of efficiency

Increase by three times by comparing with the flat die forging and thus reduce the product price.

Good quality

The internal grains of the forgeable piece after rolling are compact, whose fibers distribute along thedirection of ring, as a result of improving the fatigue strength and inner quality of the ring parts and prolonging the useful time.

Output

Weight of 3,000 kg

Height of 700 mm

Outside diameter of 2,000 mm

Monthly production of 1,800 tons

Service

Productive Cycle

1.Raw Materials

We purchased the following raw materials from several large scaled professional steelworks, and do strict spectroscopic analysis to them:

Continuous-casting of steel billet

Rolled compact

Barstock

2.Incision

Our cutting machines can automatically cut the raw material whose diameter up to 800 mm.

3.Heating: in case of environmental pollution, we adopt coal gas producer with an investment of about a million RMB.

4.Forging

Our company processes the steel to the ingot used for the grinding ring in strict accordance with the forging technology, which is developed on the basis of the raw materials which will be used and the final shape of rings.

5.Rolling

In the process of rolling, the available ingots after , through radial and axial rolling, are processed into the rings on the basis of the final size of user requirements. To this way, the machining allowance required for the manufactured rings may be kept a minimum.

6.Heat treatment

Our department of heat treatment can process the work pieces with such standard technology as normalizing, quenching, tempering and solution heat treatment.

7.Nondestructive Flaw Detection

Liquid Penetrant Test

Ultrasonic Testing

Magnetic Powder Inspection

8.We do strict mechanical testing to the products and keep the outcome for long term.

Stretching Test

Impact Test

Hardness Test
