摘要： Aluminum-killed medium carbon steel sheets, and the steel sheet stock prepared from it, is useful for manufacturing containers for a variety of food and industrial purposes. High mechanical strength is imparted to steel sheeting when the sheeting is processed through a continuous series of operations including cold-rolling and annealing. Annealing at a temperature maintained above the pearlitic transformation (Ac1) and rapid cooling yields steel sheet of high maximum rupture strength. Improved mechanical properties allows the steel sheet to be used in the manufacture of thin wall containers or containers of novel shape.

摘要： A method for heat-treating steel, which method uses a coolant having a large coefficient of heat transfer and which method treats the steel at low cost and in an environment-friendly manner (no pollution), and an apparatus for the method. The heat-treatment method cools austenitized steel in a coolant, which is a mixture of solid particles and water. It is desirable to cool the steel by passing it through a deposited layer of the solid particles in the water. It is desirable that the solid particles be oxides or graphite powders. It is also desirable to fluidize the solid particles. One type of the heat-treatment apparatus submerges steel in a coolant bath described below. The coolant bath comprises (a) a liquid bath that contains water and (b) a solid-particle bath that is partitioned in the liquid bath by a mesh and that contains solid particles. The mesh has openings smaller than the particle diameter of the solid particles. Another type of the heat-treatment apparatus treats steel by using a loaded coolant comprising water and solid particles and a means for forcibly supplying water between the solid particles. It is desirable that this type be provided with a means for fluidizing the solid particles.

摘要： This invention is directed to a method for annealing strand wires or strips in a fluidized bed reactor having an atmosphere of fluidized gases flowing through fluidized particles. The method provides for stratifying the atmosphere of fluidized gases by passing a reducing gas through the fluidized particles in the fluidized bed. The wires are passed between the fluidized particles at a location near the bottom of the fluidized bed. Finally, an amount of oxygen-containing gas is injected on top of said fluidized bed reactor.

摘要： An apparatus for manufacturing a copper wire includes a melting furnace in which combustion is performed in a reducing atmosphere so as to produce molten copper; a holding furnace for maintaining a predetermined temperature of the molten copper supplied from the melting furnace; a casting trough for sealing the molten copper supplied from the holding furnace in a non-oxidizing atmosphere and for transferring the molten copper to a tundish; a degasser provided in the casting trough for dehydrogenating the molten copper passing therethrough; a continuous casting machine for continuously producing cast copper from the molten copper supplied from the tundish, and a cutter for cutting the cast copper into a predetermined length. The apparatus permits a dehydrogenating treatment to be performed without requiring a long moving distance of molten copper, and in which the generation of holes in solidification is suppressed, whereby high quality low-oxygen copper wire having superior surface quality can be obtained.
