Notes for use of roller sleeve

Although the roller sleeve is made by multi-layer centrifugal composite and has good wear resistance and impact resistance, the following points should be noted in the use process:

1. Strictly contro

Quality control of roller sleeve

1. Smelting and casting

The microstructure of molten steel can complete the production of 50 tons of blank; The disc centrifuge can be adjusted smoothly in the range of 0~450 RPM.

1) smelting

The product ingredients are finally confirmed by the company's laboratory to ensure the consistency of the product ingredients.

(2) tanks

The automatic spraying machine is used to spray metal coating to ensure the thickness error is less than or equal to 0.5mm.

Metal mold working temperature with infrared thermometer measurement, ensure mold temperature control in the plus or minus 10 ℃.

(3) pouring

The temperature of molten steel is detected at any time with a fast primary couple.

2. Heat treatment

The outer layer has high wear resistance and inner layer has high toughness by using special equipment and microcomputer furnace group control system.

3. Machining

The company USES numerical control lathe, numerical control grinder, numerical control milling machine and so on to carry on the processing to the product to guarantee the product processing accuracy and the uniformity request.

4. Process inspection and test equipment

Chemical composition analysis: direct reading spectrometer, C S analysis, H O N joint measuring instrument, etc.

Metallographic analysis: electron microscope, microscope, imager.

Mechanical performance test: universal material testing machine,

Impact testing machine, hardness tester.

Thermal analysis: quenching dilatometer.

Thermal simulation: GLEEBLE SYSTEM3500

Stress detection: X-ray stress meter, ring core stress meter.
