Mesh-belt Carburizing & Quenching Line | Inquiry Checklist

Prepare known information first and resolve unknowns during discussion.

1. Workpieces and incoming condition
Part name, drawings or clear photos:
Material grade and certificates:
Dimensions, effective section, unit mass and areas to harden:
Incoming microstructure, previous heat treatment, oil or coating residues:
Subsequent machining, mating dimensions and allowable distortion:

2. Targets and acceptance basis
Process: carburizing and quenching. List carbonitriding or neutral hardening separately if required:
Product standards, customer specifications and editions:
Effective case depth and test locations:
Surface/core hardness, microstructure and surface requirements:
Hardness method, test force, limiting hardness and sampling:
Test reports, batch traceability and witness requirements:

3. Loading and production
Main sizes and their proportions:
Proposed layer depth or load per belt length:
Shielding, overlap, mixing, collision or individual-location restrictions:
Target output and units, e.g. kg/h:
Shifts, effective production time and changeover frequency:

4. Atmosphere, quenching and tempering
Existing process curves, atmosphere source and controls, if available:
Proposed medium, temperature control and circulation/cooling requirements, if known:
Post-quench washing/drying, permitted transfer delay and tempering requirements:
Available gas sources, washers, tempering furnaces or other auxiliary equipment:

5. Site and supply responsibilities
Available length, width, height and logistics direction:
Power/gas, process/purge gas and cooling water:
Exhaust, oil-fume and atmosphere-exhaust treatment; washing-effluent treatment:
Foundations, installation, maintenance and belt-replacement space:
Requested supplier equipment, auxiliaries and integrated-commissioning scope:

6. Contact
Company and person:
Phone, WeChat or email:
Project location and planned timing:

Part shape, furnace temperature or carbon potential alone cannot establish the complete process. Calculate capacity from representative parts, loading and continuous-operation conditions. Validate case depth, hardness, microstructure and distortion using agreed methods.
