摘要： PURPOSE:To perform pickling and descaling processes effectively in a short time by grinding a part of surface scales of a hot strip as pretreatment of pickling. CONSTITUTION:A hot strip 10 advances in the direction of the arrow, and carried to a flap roll grinder 7 through pinch rolls 11, bridle rolls 12, a looper 13 and bridle rolls 14. The flap roll grinder 7 is installed just before a pickling tank 8 and pinch rolls 15 and 16 are arranged before and after the flap roll to grind the hot strip 10. By grinding a part of surface scales of the hot strip 10 the thickness of the scale is reduced and fine cracks are generated by grinding. Thus, intrusion of pickling agent in the succeeding process is facilitated.

摘要： PURPOSE:To save fuel consumption by conducting the waste gas discharged from the inside of an inner cover to between the inner cover and an outer cover and burning the same in a method of performing batch type coil annealing in an atmosphere contg. hydrogen. CONSTITUTION:The atmosphere gas contg. hydrogen supplied through a supply gas pipe 1 into an inner cover 2 reacts partly with the N2 and S in coils, after which it passes through a gas discharge pipe 3 and is conducted into the 5 between the cover 2 and an outer cover 4. A pressure regulator 6 regulating the pressure in the cover 2 is provided to the mid-part of the pipe 3. The waste gas contg. hydrogen conducted into between the cover 2 and the cover 4 by the pipe 3 generates heat by reacting with the excess oxygen in the combustion flames ejected from direct fire burners 7 and the high temp. developed by the burners 7.

摘要： PURPOSE: To prevent the troubles in the handling of solidified pitch, by dividing the thermal polymerization process of pitch in two stages, heat-treating the pitch in the first thermal polymerization step until the pitch is about to form the mesophase, storing the product in liquid state, and supplying the liquid to a spinning apparatus furnished with a vacuum thermal polymerization apparatus.
CONSTITUTION: Pitch is made to react with a hydrogen-donative solvent, alcohol, phenol, etc., and the solvent is removed from the reaction product. The processed pitch is subjected to the thermal polymerization at 400W500°C to the state immediately before the formation of meso-phase, and is stored in liquid phase. The stored liquid pitch is supplied to a spinning apparatus furnished with a vacuum thermal polymerization apparatus, heated quickly to 400W550°C under reduced pressure to develop the meso-phase, and is spun as it is to obtain the objective pitch fiber.

摘要： PURPOSE:To eliminate entirely a roll pickup phenomenon in a high temperature reducing atmosphere, by using a steel plate supporting device of a hearth roll system, and that of a floating system, for a weak oxidizing atmospheric zone and a high temperature reducing atmospheric zone, respectively. CONSTITUTION:A grain oriented electromagnetic continuous band steel 1 goes into a heating zone 2 of a weak oxidizing atmosphere of a hearth roll system, is heated, and is soaked in a soaking zone 3 of the same atmosphere of the same system. Subsequently, it goes into a heating zone 4 of a high temperature reducing atmosphere of a floating system, is soaked in a soaking zone 5 of the same atmosphere of the floating system, and thereafter, goes into a jet system cooling zone 6 of the floating system. In this zone, it becomes a specified temperature or below, passes through a hearth roll system cooling zone 7, and annealing ends. In this way, a roll pickup phenomenon which has been generated in the high temperature reducing atmosphere up to the present is entirely eliminated.
