CCM Spare Parts for Continuous Casting Machines
LONSUN supplies copper mould tubes, copper mould plates and customized continuous-casting spare parts for billet, bloom, round, slab and beam-blank casters. Selection is based on caster design, strand section, taper, material, coating, cooling and operating conditions.
Discuss Your CCM Spare Parts RequirementCCM spare parts are consumable and replacement components used in continuous casting. Copper mould products form and cool the initial strand shell, so dimensional accuracy, taper, copper grade, coating and cooling-channel design must be tied to the caster and steel grade. Other parts are supplied by drawing and working position.
CCM Spare Parts and Applications
The current page uses copper mould tubes and plates as the main representative products while retaining a broader customized CCM spare-parts direction.
| PRODUCT | APPLICATION | MATERIAL / COATING DIRECTION | TYPICAL INQUIRY INFORMATION |
|---|---|---|---|
| Copper mould tube | Billet, bloom and round continuous casting | TP2, CuAg, CuCrZr; chrome or alloy coating | Section, length, radius, taper, coating and caster model |
| Copper mould plate | Slab continuous-casting mould | CuAg, CuCrZr, CuNiBe; NiCo, alloy or ceramic coating | Wide/narrow face, dimensions, cooling channel, taper and drawing |
| Mould assembly | Mould-system matching and replacement | Customized according to caster design | Assembly drawing, installation data and cooling condition |
| Related CCM parts | Foot roller, segment roller, dummy bar, spray nozzle and tundish parts | Customized by position and working condition | Product drawing, material, steel grade and maintenance requirement |
Trade names for copper alloys and coatings are not enough for final selection; drawing revision, substrate condition, coating thickness/area and acceptance method must be agreed.
Mould Selection and Technical Reference
A mould tube or plate must match heat transfer, strand geometry, withdrawal and cooling. The following inputs form the technical baseline for specification review.
Key Technical Inputs
| REVIEW AREA | DATA TO DEFINE | TECHNICAL PURPOSE |
|---|---|---|
| Caster and strand | Caster model, billet/bloom/round/slab/beam-blank section, radius and casting direction | Defines mould type, geometry and installation interface |
| Geometry and taper | Drawing, length, inner profile, single/multi/parabolic taper and corner design | Matches shell shrinkage, withdrawal and strand shape |
| Copper material | TP2, CuAg, CuCrZr, CuNiBe or approved equivalent and heat-treatment condition | Balances thermal conductivity, strength and service condition |
| Coating | Chrome, NiCo, alloy or ceramic direction; thickness, area and surface preparation | Controls wear and thermal behavior at the working surface |
| Cooling and acceptance | Water quality/flow/pressure, channels, dimensional report, coating test and inspection documents | Confirms cooling compatibility and release criteria |
Final dimensions, taper, copper grade, coating and cooling-channel design must follow the approved caster drawing and agreed operating data.
Common CCM Mould Problems and First Review
Mould life and strand quality depend on design, copper/coating condition, cooling, casting practice and alignment. Review the mould and caster records together.
| SYMPTOM | POSSIBLE AREAS TO CHECK | INFORMATION NEEDED |
|---|---|---|
| Premature wear or coating loss | Coating direction/thickness, casting speed, steel grade, lubrication/flux, taper and surface condition | Campaign/cast length, wear map, coating measurements, steel mix and operating record |
| Cracks or local damage | Thermal cycling, cooling irregularity, stress concentration, handling and coating/substrate condition | Defect location, photographs, cooling data, event history and inspection results |
| Poor strand surface or shape | Taper/profile, mould alignment, oscillation, flux, cooling, steel grade and withdrawal condition | Defect pattern, strand section, caster settings, taper drawing and mould measurements |
| Cooling leakage or blockage | Channel condition, water quality, deposits, seals, connections, pressure and flow | Leak location, water analysis, pressure/flow record, channel drawing and maintenance history |
| Installation mismatch | Drawing revision, flange/interface, radius, datum, accumulated equipment wear and site modification | Approved drawing, site measurements, mating components, photographs and trial fit |
Safety note: continuous-casting mould inspection and replacement involve hot metal systems, cooling water, lifting and stored energy; follow the plant’s isolation, cooling and lifting procedures.
RFQ and Procurement Checklist
A complete CCM RFQ must identify the caster and drawing before material or coating is quoted.
