In a finish heat treatment method and finish heat treatment apparatus for an iron powder, a raw iron powder is placed on a continuous moving hearth and continuously charged into the apparatus. In the pretreatment zone, the raw iron powder is subjected to a pretreatment of heating the raw iron powder in an atmosphere of hydrogen gas and/or inert gas at 450 to 1100° C. In decarburization, deoxidation, and denitrification zones, the pretreated iron powder is subsequently subjected to at least two treatments of decarburization, deoxidation, and denitrification. In the pretreatment zone, a hydrogen gas and/or an inert gas serving as a pretreatment ambient gas is introduced separately from an ambient gas used in the at least two treatments is introduced from the upstream side of the pretreatment zone and released from the downstream side so as to flow in the same direction as a moving direction of the moving hearth. |

PROBLEM TO BE SOLVED: To provide a method and an apparatus for finish heat treatment of iron powder, which can produce product iron powder with a desired target concentration range in a stable manner at a high productivity, regardless of impurity content of crude iron powder that is raw material of the iron powder.SOLUTION: The crude iron powder is loaded on a continuous moving bed 9 and charged into a finish heat treatment apparatus. The crude iron powder is subjected to a preparatory treatment at first in the preparatory treatment zone 31, to be heated at the temperature range of 450-1,100°C in hydrogen gas and/or inert gas atmosphere, then, followed by at least two kinds of treatments among decarburizing, deoxidizing and denitrifying, in the decarburization zone, deoxidization zone and denitrification zone respectively. In the preparatory treatment zone, besides the atmospheric gas used for at least two kinds of the treatments, hydrogen gas and/or inert gas is introduced from the upstream side 50 of the preparatory treatment zone 31 as the atmospheric gas, and discharged from the downstream side 6 so that the gas flows in the same direction as the moving direction of continuous moving bed 9. |

According to the present invention there is now provided a body cemented carbide provided with at least one wear resistant layer, which body contains a toughness increasing surface zone. Increase in toughness is obtained due to the presence of a surface zone having increased WC grain size and/or increased Co content. The invention is most suitable for WC—Co cemented carbides. |

The invention relates to a method for producing a steel shaped body, particularly, for example, a component for common rail fuel injection valves, comprising the method steps of: forming a powderous composition based on iron oxide, from oxide particles, with the addition of carbon and micro-alloy elements so as to adjust a bainitic microstructure; heating the powderous composition to a sinter temperature; reducing the shaped body obtained by sintering; and cooling the sintered shaped body to room temperature. As a result, from the three essential state phases in a state diagram (10), specifically the ferrite-perlite state range (11), the bainite state range (12) and the martensite state range (13), preferably the bainitic state phase is formed in a medium temperature range by the ferrite-perlite state range (11) being shifted to longer cooling periods and the martensite state range (13) being shifted to lower temperatures. |
