Abstract: A silicone elastomer cured product having radical reactivity obtained by curing a composition is disclosed. The composition comprises (A) a chain organopolysiloxane having a curing reactive group, and optionally (B) an organohydrogen polysiloxane, (C1) a curing agent, and (D) an organopolysiloxane resin. The surface of the cured product has radical reactivity with, for example, an adhesive, and is easily removable along with, for example, adhesive tape after use as a protective material. In general, the cured product has excellent heat resistance and flexibility and exhibits good adhesion and conformity to a substrate so as not to separate from a substrate even when the cured product is cut together with the substrate while remaining easily removable from the substrate when desired. A protective material for an electronic component made of the cured product is also disclosed.

Abstract: A method of controlling the rolling efficiency in a continuous hot rolling process. A rolling schedule and a conveying schedule are determined on a mill line for the slabs arranged in succession based on an aimed extraction temperature of the slabs from a heating furnace and a predetermined temperature at the exit of a finish mill. A minimum extraction pitch is calculated for the slabs from the heating furnace under restriction of the side of the mill line, and a different minimum extraction pitch is calculated for slabs from the heating furnace under restriction of the side of the heating furnace based on slab temperature charged to the heating furnace and the aimed extraction temperature. An optimum extraction pitch is determined for slabs from the heating furnace by comparing both of the minimum extraction pitches. With such a method, the continuous hot rolling operation is carried out under an optimum condition.
