Mica Slip Plane materials (in roll or sheet form) is a result of specially pressed mica product which is made of phlogopite mica paper , glass fiber cloth , silicon resin and special layer like ceramic cloth or stainless steel. The thickness ranges from 0.2mm to 2.5mm, tensile strength is above N/15mm and temperature resistance is above 800°C. Mica Slip Plane materials are primarily designed to separate refractory linings from the coil grout of coreless induction furnaces and offer the following benefits:
• provides superior slip plane properties and protects the inductor coils from the expansion and contraction forces caused by thermal expansion of refractory lining
• provides electrical insulation between the energized coil and the molten metal
• optimizes the heat flow to prevent over-sintering of the refractory lining
• prevents early leakage and subsequent costly damage to the coil
• facilitates the “push out” of worn crucibles/linings
• extends the life of the crucible/refractory thereby reducing maintenance costs and down time
