Ⅰ. Watch the 300 mm Disc Induction Hardening Process

영상: Super-audio-frequency induction hardening application for the outer circumference of a 300 mm disc.

The demonstration shows a circular metal disc with a central hole positioned inside a circular induction coil. 가열 중, a continuous red-hot band develops around the outer circumference, while the central portion remains comparatively dark.

The video presents the process as suitable for uniform peripheral hardening. Confirming hardness uniformity requires testing of the hardened surface.

The video identifies the application as induction hardening, although the visible footage primarily shows the heating stage rather than the subsequent quenching operation.

Ⅱ. Workpieces and Industrial Applications

This induction hardening arrangement is intended for circular components that require localized treatment around their outer diameter.

For suitable hardenable steel parts, peripheral hardening may be used where the outer surface is subject to wear or mechanical contact, while the main body does not require the same hardened condition.

잠재적인 응용 분야는 다음과 같습니다.:

— Steel discs requiring outer diameter hardening.

— Circular mechanical components with wear-resistant outer surfaces.

— Disc-shaped power transmission components.

— Suitable flanged components requiring peripheral hardening.

— Custom circular steel parts with localized surface-hardening requirements.

Relevant manufacturing sectors may include general machinery, industrial equipment, power transmission equipment and heavy machinery.

Ⅲ. How the Induction Hardening System Works

The heating arrangement uses a circular inductor positioned around the workpiece’s outer circumference.

When the induction power supply energizes the coil, the alternating magnetic field induces electrical currents within the metal component. The resulting heat is concentrated in the region coupled to the inductor.

The complete hardening process involves coordinated workpiece positioning, induction heating and 담냉.

공작물 포지셔닝

The disc is supported and located relative to the induction coil. The fixture must maintain the required position and clearance while accommodating the workpiece geometry and heating conditions.

Peripheral Induction Heating

The circular inductor directs electromagnetic energy toward the outer circumference.

코일 기하학, 전력, 주파수, heating time and coupling conditions influence the resulting temperature distribution.

이 애플리케이션의 경우, the heating arrangement is intended to produce a circumferential heating band suitable for the required hardening process.

담금질

For a suitable hardenable steel, the required surface structure is produced by heating the selected region to the appropriate austenitizing condition and applying a suitable quenching process.

The quenching method must be matched to the material, 필요한 경화 깊이, workpiece geometry and allowable distortion.

Heating uniformity alone does not establish hardness uniformity. The final hardening result depends on both the heating and quenching stages.

Ⅴ. Customized Induction Coil and Workpiece Tooling

The circular induction coil is a key part of the equipment configuration.

Its geometry is selected to match the disc’s outer diameter and the required width of the heating band. 코일과 공작물 사이의 여유 공간, electrical matching and the distribution of electromagnetic energy must also be considered.

For different disc geometries, the design may need to account for:

— Outer diameter and workpiece thickness.

— Width and location of the hardened area.

— Peripheral profile and surrounding features.

— Coil clearance and workpiece positioning.

— Required heating depth and temperature distribution.

이 300 mm disc shown in the video is one application example, not a fixed equipment size limit.

Workpiece fixtures are also selected for the production process. A simple positioning arrangement may be sufficient for some applications, while others require dedicated clamping, handling or movement mechanisms.

코일, fixture and heating process should be developed together to achieve the required treatment area.

Ⅴ. Complete Induction Hardening Equipment Configuration

KOTRON supplies induction heating and hardening equipment solutions covering the power supply, 맞춤형 인덕터, workpiece tooling, quenching equipment and associated control and automation systems.

For disc outer diameter hardening, the equipment scope is established according to the required process and the customer’s existing production facilities.

Power Supply and Process Control

The demonstrated application uses super-audio-frequency induction heating.

For a new project, 그 작동 주파수 and power must be selected according to material properties, 작업물 치수, required hardened depth and heating conditions.

The control arrangement can be specified to coordinate heating parameters and the relevant machine operations.

Quenching Integration

For a complete hardening process, the quenching equipment must be coordinated with the heating stage.

Quenchant selection, cooling conditions and quenching timing affect the resulting hardness and dimensional stability. The actual arrangement is established during process development.

Automation and Production Integration

일괄 생산용, the equipment may incorporate programmable workpiece positioning, 자동 로딩 및 언로딩, and coordinated process control.

The required automation level is determined by the production cycle, workpiece variety, handling requirements and available factory layout.

Ⅵ. Selecting the Right System for Disc Outer Diameter Hardening

Disc diameter is only one factor in selecting an induction hardening system.

재료, 단면 두께, required hardened area and production conditions must be evaluated together.

선택 요소	엔지니어링 고려 사항
재료	Hardenability and heating/quenching requirements
Workpiece Dimensions	코일 크기, fixture design and heating demand
Hardening Area	Position and width of the required hardened band
목표 경도	Required surface properties
효과적인 케이스 깊이	Heating frequency, thermal cycle and quenching requirements
생산 요구 사항	Processing sequence, handling and automation
Existing Equipment	Scope of integration with available production systems

Where a specified surface hardness or hardened depth is required, the process should be developed and verified through appropriate testing.

For components that require hardening on an internal surface instead of the outer diameter, KOTRON also offers an 내부 보어 유도 경화기 for automotive and motorcycle precision parts.

Ⅶ. 자주 묻는 질문

답변을 펼치려면 질문을 클릭하세요..

Can the system process discs larger or smaller than 300 mm?

Different workpiece sizes can be evaluated by selecting appropriate induction coils, power supplies and fixtures. The actual working range must be established for the selected equipment configuration.

Does the system heat the entire disc?

The demonstrated induction coil is arranged to concentrate heating around the outer circumference. Heat also conducts into adjacent material, so the actual heating distribution depends on the workpiece and process conditions.

Can uniform hardening be achieved around the disc circumference?

The circular inductor is intended to support circumferential heating. Achieving the specified hardness distribution also requires suitable material, controlled heating and quenching conditions. The result should be verified by hardness testing where required.

Can the system be supplied with quenching and automation equipment?

네. Complete solutions can include the induction power supply, customized coil, workpiece tooling, 담금질 장비, control system and required automation. The final supply scope is defined for each project.
