In one of the glass sheet tempering process in which a glass sheet is submerged into molten metal with electromagnetic force by Linear Induction Motor (LIM), it is necessary to keep the glass sheet vertical in the center of molten metal tank. Because a glass sheet warps unless its both sides are uniformly cooled.<br>This paper describes an idea of buoyant force center on a glass sheet in molten metal which is introduced to discuss its stability against tilt. If the buoyant force center of a glass sheet is higher than its gravity center, it is stable against tilt. Numerical simulation of electromagnetic fluid flow is performed to evaluate the buoyant force center. Its stable conditions obtained are the followings:<br>(1) The shortest length of a glass sheet is 2τ/3 shorter than that of LIMs.<br>(2) The lowest limit of the gravity center of a glass sheet is τ/3 higher than the center of LIMs.<br>where τ is the pole pitch of LIMs.
