摘要： The specification discloses a sealing apparatus for wind boxes at the ore supply side and ore discharge side of a DL type sintering machine, which is provided with a plurality of sealing members series-arranged in contact with the lower surface of a pallet in the sintering machine, and a seal chamber communicating with spaces between these sealing members. Each of the seal members consists of a rotatable rolls having radially projecting seal plates on the outer circumferential surface thereof. It may also consist of a roll having such radially projecting seal plates closely contacting the bottom surface of a pallet and the inner surface of a seal chamber, or a roll having flat seal plates the flat surfaces of which are pressed against the bottom surface of a pallet. Since an independent air extracting exhaust fan is provided in the seal chamber, the sealing performance can be further improved. According to this apparatus, the rate of generation of a sintering exhaust gas decreases, and electric power for a main fan and the processing costs for desulfurization and denitration apparatuses in the subsequent steps can be reduced.

摘要： Improved sintered alloy steel is produced by (1) mixing powdery stainless steel with a binder, moulding it and removing the binder by heating, (2) sintering the moulding under a reduced pressure of 30 Torr or less at 1000-1350 deg.C, and (3) resintering it in a non-oxidative atmos. eg. mixt. of inert gases contg. nitrogen, under normal pressure at a temp. higher than those of (1) and (2), 1250-1400 deg.C. The mean particulate size of the powdery stainless steel is 15 micro of less. When the binder is removed from the moulding by heating at (1), the C/O mole ratio of the moulding is adjusted to be 0.3-3.0. At (2) the C/O mole ratio is adjusted to 0.3-3.0. Pref. powdery stainless steel contains Cr (16-25 wt.%) and Ni (8-24 wt.%). Obtd. stainless alloy steel has the following properties: a stainless steel compsn., a density ratio of 92% or higher, max. radius of the pores in the organisation of 20 micro or less. The amt. of Cr in the surface of the sintered alloy steel is 80% or more of the amt. of Cr in the interior.

摘要： A hardening apparatus is constructed so that a heated metal pipe is rotatably retained by retaining means so that it is pressed thereby from both above and below. The metal pipe is dipped into cooling water within a water tank by dipping means, and in addition, jets of cooling water are applied to both the inner and outer peripheral surfaces of the metal pipe by cooling water spraying means. After being rapidly cooled in this way, the metal pipe is transported out of the water tank by a transport means. In this apparatus, the metal pipe is not dropped from a height, so it is possible to prevent the surface of the metal pipe becoming flawed, and the rotation of the metal pipe makes it possible to promote what is effectively a stirring of the cooling water. It is also possible to constantly change the portions of the retaining means in contact with the metal pipe, so that the metal pipe can be rapidly and uniformly cooled, and therefore can be well hardened.

摘要： Apparatus for automatically loading on and unloading from multi-stage receiver arms of a rack, articles which are conveyed being suspended by, for example, a crane, through a lifting device. The rack is composed of a base, supports vertically provided on the base, and a plurality of multi-stage receiver arms provided such as to be able to project sidewardly from the supports when supporting articles, the receiver arms being adapted to be housed in the supports in a normal state and emerge therefrom according to need. The receiver arms are interlocked with each other in such a manner that, as the receiver arms which in combination constitute each of the stages adjacent to each other in the vertical direction, move from stand-by positions to receiving positions, the receiver arms which in combination constitute an upper stage, move from inoperative positions to stand-by positions in response to the actions of the first-mentioned receiver arms. It is possible for this apparatus to operate fully automatically without any manual operation and to load and unload articles reliably, speedily and safely. Further, since the lifting device is provided with a stopping component which limits the range of movement of the lifting device, particularly the lowering movement, there is no danger of articles or the floor being damaged.

摘要： Tin-containing iron powder comprising powder particles mainly composed of iron having formed on the surface thereof a tin-rich portion wherein at least part of the tin is in the form of a compound with iron and the content of total tin is 1 to 20 wt %. This tin-containing iron powder is produced by mixing a powdered tin compound capable of being decomposed by heat to produce metallic tin with a powder mainly composed of iron, and heating the mixture to 450 to 700oC in a reductive or non-oxidative atmosphere. This tin-containing iron powder can be sintered to yield a product having a high density and excellent magnetic properties.
