Electric heating type rolling device

An electric heating type rolling device for rolling a metal strip moving in a direction, comprising:

• at least one pair of work rolls for rolling said metal strip while contacting the metal strip;
• a power supply for generating a pulse current;
• and
• first and second conductive electrode means which are electrically connected to said power supply for applying said pulse current to said metal strip, the first conductive electrode means being disposed in a location before said metal strip passes through said work rolls, and the second conductive electrode means being disposed opposite to the first conductive electrode means in a location after said metal strip has been rolled by said work rolls and passed thereby,
• wherein said first and second conductive electrode means respectively consist of a pair of plate-shaped contact members which are disposed contactingly above and below said metal strip, each said contact member including a first contact portion contacting said metal strip, a second contact portion contacting said metal strip at a position closer to said work rolls than said first contact portion, and a flat portion for connecting said first contact portion and said second contact portion while being spaced apart from said metal strip.
