LHR3091 Lab Heating Rolling Mill ±2μm Cylindricity ATOMFAIR®

This equipment operates with heated rolls and electrical power, requiring careful management of thermal and electrical hazards. The high surface hardness and precision cylindricity of the rolls demand cautious handling to avoid mechanical injury.

• Thermal Limit: Operate within the prescribed temperature envelope to prevent overheating of roll components and surrounding materials.
• Electrical Safety: Verify that the power source matches the device electrical specification before connection to avoid shock or damage.
• Mechanical Hazard: Keep hands and loose clothing away from the roll nip during operation to prevent crushing injuries.
• Roll Surface Protection: Avoid contact with hard or abrasive objects that could damage the chrome-plated roll surface finish.
• Ventilation Requirement: Ensure adequate airflow around the unit to dissipate heat accumulated during extended use.

This procedure covers initialization, material feeding, and safe shutdown of the lab heating rolling mill. Follow these steps to achieve consistent rolling results while mitigating thermal and mechanical risks.

Required Equipment: Thermally insulated gloves, Feed guide or tweezers for thin strips

1. Inspect Machine
   Inspect the roll surfaces for debris or damage and confirm the emergency stop functions correctly.
2. Set Temperature
   Set the desired roll temperature via the digital thermostat, allowing sufficient warm‑up time until stable.
3. Adjust Roll Gap
   Adjust the pressing gap using the inclined block mechanism to match the required final thickness.
4. Set Feeding Speed
   Set the feeding speed to an appropriate rate for the material being processed.
5. Feed Material
   Feed the strip material between the rolls using the guide, ensuring it enters evenly and straight.
6. Initiate Rolling
   Start the rolling process using the forward direction, monitoring temperature and thickness continuously.
7. Reverse and Remove
   Reverse the rolls to release the processed strip, then power down the heating element and allow cooling before cleaning.

The Atomfair-LHR3091 is a compact lab-scale heating rolling mill designed for small-batch processing of battery materials and precious/non-ferrous metals, offering adjustable temperature up to 200°C and precise thickness control with ±2μm cylindricity rolls.

Positive

• High rolling precision: Roll cylindricity ≤±2μm ensures consistent and accurate sheet thickness for battery plate densification and thinning.
• Hard chrome rolls HRC62: Surface hardness above HRC62 with hard chrome plating provides excellent wear and rust resistance, extending roll life and maintaining surface finish.

Trade-offs

• Limited temperature range: Maximum rolling temperature of 200°C may not be sufficient for materials requiring higher thermal processing conditions.
• Narrow thickness and width limits: Rolling thickness is restricted to 0–2mm and pressing width to 0–100mm, confining use to thin, narrow strips only.
