There are two main ...

$begingroup$ Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.
A battery short circuit is a condition where the electrical current in the battery bypasses the normal flow of electrons through the circuit. This can happen if the positive and negative terminals of the battery are accidentally touched together, or if a wire that is connected to the battery becomes frayed or broken.

Because the same voltage is applied across a lower resistance, more current flows, and the wire heats up more. Eventually, when you make the steel wire short enough, so much current flows that it melts the wire. Even the copper wire becomes warm. In a normal electric circuit, an electric current powers an appliance, such as a refrigerator or TV.
