摘要： PURPOSE:To make it possible to perform heating to a suitable temp. at a minimum fuel consumption per unit product, by calculating the temp. of each slab in each zone, and by determining the correcting quantity of furnace temp. in each zone so that each slab may be in a prescribed temp. range including lower limit temp. at the point where the slab is conveyed a prescribed distance. CONSTITUTION:In a continuous multiple zone heating furnace including a preheating zone, a heating zone, and a soaking zone, the temp. of each slab in the furnace is determined by calculating on the basis of furnace temp., heat-transferring characteristics of the furnace, the dimensions, the heating property, and the heat hysteresis of each slab. Then furnace temp. at subsequent time in the adjacent zone on the discharge side of a zone where the slab stays is assumed, and the furnace temp. in each zone, assumed furnace temp. at subsequent time in the zone on discharge side are corrected so that the temp. of all slabs in each zone when each slab is conveyed a prescribed distance from the present position may come into the target temp. range, and one or more slabs may be at the lower limit temp., hereby the quantity of correction for the furnace temp. in each zone is determined.

摘要： PURPOSE:To provide an injector with a higher agitation effect between a dispersion medium and a lubricating oil by forcing the lublicating oil by means of a pitot tube near the frontmost of a reopened passage following the throttled part of a dispersion medium passage. CONSTITUTION:A dispersion medium passage 2 of an injector 1 is provided at the rear with a throttled passage 7 following which a reopened passage 8 is provided. A pitot tube 5 is projected near the frontmost position of the passage 8 in such a direction as to counter the flow of the dispersion medium. Then, the dispersion medium to be fed at a constant velocity is accelerated through the throttled passage 7 and hits a dispersed phase injection port of the pitot tube 5. At this point, a lubricating oil forced from the pitot tube 5 is stirred rapidly divided into fine particles while mixed into the dispersion medium to form a stable emulsion.

摘要： PURPOSE:To exceedingly facilitate generation of air bubbles and remarkably heightening the evaporating heat transfer coefficient by forming build-up portions on the tip end sides of outer fins to narrow the interval between the fins and to form an opening interval easy for generation of air bubbles, and forming inner cavities widened toward the inner parts at the lower parts of the build-up portions to stably hold air bubble nucleuses. CONSTITUTION:Spiral fins 2 are formed around the outer periphery of a heat transfer tube material 1, and metal build up portions 3 made up of aluminum or the like are formed on the tip end sides of the fins 2. The thickness (f) on the tip end side is made larger than the thickness T on the root side [as a result, the interval (l) between the tip end sides of adjacent build-up fins is narrower than interval L on the root side]. As a result, spiral cavities widened toward the inner part, having fine spiral openings 4 are formed on the surfaces of the heat transfer tube material 1. The heat transfer tube having the above described structure is designed so that the interval (l) of the spiral opening 4 is in a range of from 20-100mum in which generation of air bubbles is easiest. Consequently, air bubbles are generated smoothly by the heat transfer tube by being stimulated by air bubble nucleuses within the inner cavities.
