Zhaoqing Feihong Machinery & Electrical Co., Ltd has focused on heating tube manufacturing equipment development since 1992. As an experienced industrial machinery manufacturer, we independently design and produce Short Circuit Heating Equipment for Tube Annealing Treatment. This thermal processing machine adopts advanced short-circuit heating principle to carry out annealing treatment on semi-finished heating tubes. When matched with pipe shrinking machines and bending equipment, it optimizes the whole heating tube production workflow for heating element manufacturers all over the world.
Working Principle
This annealing processing unit relies on mature short-circuit heating technology to deliver controllable thermal energy to metal heating tubes. The targeted heating process changes the metal internal structure, lowers surface hardness and eliminates residual stress generated in cold forming procedures.
1. Conduct concentrated heating on designated tube sections by short-circuit heating method
2. Realize material softening after constant temperature heat preservation
3. Avoid excessive overall heating and effectively control processing cost

FAQ – Purchasing Questions
Q1: Can short circuit heating technology achieve consistent annealing softening effect?
A1: Yes. Short Circuit Heating Equipment for Tube Annealing Treatment features stable power output within 35-80KW range. Operators can adjust heating parameters according to tube material and wall thickness, so uniform softening effect can be obtained, effectively reducing tube surface hardness steadily in mass production.
Q2: Is there any special requirement for workshop environment to install this annealing equipment?
A2: Basic industrial environment with three-phase 380V power supply and stable 0.6Mpa air source is required. The machine adopts compact layout. No special heat insulation room is necessary compared with large heating furnaces. Regular ventilation in production workshop meets daily running demands.
Q3: Can I buy the machine first and add automatic feeding structure later?
A3: Support delayed upgrading. We reserve installation interface for automatic feeding assembly on the main machine frame. Customers can purchase the standard manual feeding version first. When production capacity expands in the future, you can order the automatic feeding module separately for retrofitting without buying a new whole machine.
Q4: How long will it take to deliver after order confirmation?
A4: The delivery cycle depends on machine configuration. Standard FH-147 main unit has relatively fast delivery. If you need customized automatic feeding structure or special fixture adjustments, our sales team will confirm exact lead time after receiving your technical requirements.
