Solid Rolled multiple wear Wheels of Diesel and Electric Locomotives:
- This standard covers the requirements of heat treated solid rolled multiple-wear wheels for Diesel and Electric locomotives of all gauges.
- Any special requirements given in the relevant drawings will override this specification.
Process of steel manufacture:
- The wheels shall be manufactured from steel made by Electric, Basic Oxygen or any other process recognized as equivalent by the purchaser. The steel shall be of killed quality.
- The steel shall be vacuum degassed and hydrogen content in liquid steel shall not be more than 2.5 PPM. Hydrogen analysis shall be done as given in Para 2.1.2 & 2.1.3.
- The sample of liquid steel shall be taken from the ladle by plunging the sampler 300 mm below the molten metal-slag interface. The sample shall be held 2-3 seconds and then quenched in cold water so that the sample temperature falls below 150°C within 5 seconds.
- The sample shall be removed from cold water and immediately packed in dry ice or liquid Nitrogen. The sample shall be analyzed within 48 hours and till the time of analysis, the sample shall continually be fully covered by dry ice / liquid Nitrogen.
- Sampling shall be done by 6 mm diameter tube of Pyrex glass or ceramic which does not react with steel. General wall thickness of the tube shall be 1.5 mm and at the fill end 0.5 mm approx. The tube should be under a vacuum of 10-3 bar (0.76 mm of Hg). Any other method of sampling shall have a prior approval of the purchaser.
- The analysis of the sample shall be done by Inert Gas Fusion technique in which the sample is fused at around 1900°C in the induction heating crucible. A Nitrogen carrier gas transports the released Hydrogen to a thermal conductivity cell. The amplified and integrated output of the cell is to be calibrated for Hydrogen in PPM.
- A Leco-RH-3 Hydrogen analyzer or similar precision equipment may be used for Hydrogen determination. Hydris systems may be used for online / instantaneous measurement of Hydrogen content in liquid steel.
- Any other method for Hydrogen Analysis shall have a prior approval of the purchaser.
Manufacturing of Wheel:
- The wheels shall be manufactured by forging and rolling process from cropped ingots or from cheeses of steel blooms of suitable section, length and weight, manufactured by the continuous casting method, in such a manner that the central axis of the ingot or the bloom coincides with the axis of the wheel. Sufficient discard shall be made from both ends of each ingot to ensure freedom from piping and undesirable segregations. Each ingot shall be of suitable section and length to produce two or more wheel blanks after top & bottom discards have been made to eliminate the defective portion completely.
- The steel shall be refined in the ladle furnace and vacuum de-gassed. Suitable shrouding arrangements from the ladle to tundish and from tundish to mould shall be made. The continuous casting machine shall have the facility of electromagnetic stirring.
- The minimum cross section of the cropped ingot or continuously cast bloom shall be such that a minimum reduction ratio of 4:1 is obtained with the maximum wheel section at rim portion. That is, the original height of the cropped ingot piece should be at least 4 times the height of the rough wheel at the rim.
- The minimum cross section of the cropped bloom manufactured from ingot rolled down to bloom size shall be such that a minimum reduction ratio of 3:1 is obtained with the maximum wheel section at rim portion. That is, the original height of the cropped bloom piece should be at least 3 times the height of the rough wheel at the rim.
