Portable stripping head induction heating system for stripping coated and lined metal objects and surfaces and methods for stripping coated metal objects and surfaces

An induction heating system comprising:

• an electrical power supply;
• first and second primary leads electrically connected to set power supply, said first and second primary leads being constructed of elongate, flexible electrical cable;
• first and second capacitors electrically connected, respectively, to send first and second primary leads;
• first and second secondary leads electrically connected, respectively, to said first and second capacitors, said first and second secondary leads being constructed of elongate, flexible electrical cable;
• and
• stripping head means electrically connected to said first and second secondary leads.

A method for heating metallic items for loosening coatings or protective lawyers adhered thereto comprising the steps of:

• selecting and induction heating system comprising:
• an electrical power supply;
• first electrical lead means electrically attached to said electrical power supply, said first electrical lead means for conducting electrical power from said electrical power supply to capacitor means;
• capacitor means electrically connected to said first electrical lead means;
• secondary lead means electrically connected to said capacitor means, said secondary lead means for conducting electrical currents to or from said capacitor means;
• stripping head means including an electrically conductive coil member electrically connected to said secondary lead means.
• juxtaposing in said stripping head means to a metallic item to which is adhered a to-be-removed coating or protective layer;
• actuating said the electrical power supply;
• maintaining said stripping head means in juxtaposition with said metallic item for a time sufficient to heat said metallic item and loosen said coating or protective layer from said metallic item.

A method for stripping rubber-like linings from chemical transport tank cars and trailers and from chemical storage tanks comprising the steps of:

• selecting an induction heating system comprising:
• an electrical power supply;
• first electrical lead means electrically attached to said electrical power supply, said first electrical lead means for conducting electrical power from said electrical power supply to capacitor means;
• capacitor means electrically connected to said first electrical lead means;
• secondary lead means electrically connected to said capacitor means, said secondary lead means for conducting electrical currents to or from said capacitor means;
• stripping head means including an electrically conductive coil member electrically connected to said secondary lead means.
• actuating said the electrical power supply;
• juxtaposing said stripping head means to a first portion of the lining of a tank car or tank to which is adhered a to-be-removed coating or protective lining;
• maintaining said stripping head means in juxtaposition with said first portion for a time sufficient to heat a corresponding first portion of the underlying metal of said tank car or tank to loosen said coating or protective lining therefrom;
• juxtaposing said stripping head means to a second portion of the lining of a tank car or tank to which is adhered a to-be-removed coating or protective lining;
• and
• maintaining said stripping head means in juxtaposition with said second portion for a time sufficient to heat a corresponding second portion of the underlying metal of said tank car or tank to loosen said coating or protective lining therefrom.
