The powder-rolling device () includes: a pair of rolling rolls () to attach powder material (Y) to a sheet-shaped base material (X) by pressure; a preliminary press roll () to press the powder material (Y) to a circumferential surface of a rolling roll () before the powder material (Y) is attached to the base material (X) by pressure; and a support device () supporting the preliminary press roll () movable, so that a load applied to the preliminary press roll () becomes equal to a set value which has been set beforehand.

Powder-rolling device and powder-rolling method

Provided are a method for producing a clad material, and a clad material which can prevent a brazing filler metal layer from having a higher melting point so as to prevent the strength degradation and thermal deformation of a metal material, which can reduce production costs, which can reduce in thickness the layer to prevent sagging of the brazing filler metal upon brazing and which can improve press formability. A powder press-fixing machine is used to press-fix metal powder to surfaces of a base material uncoiled from a coil by an uncoiler. In order to provide a required composition of brazing filler metal, at least two kinds of metal powder is mixed, the mixed powder being press-fixed to the base material to form the brazing filler metal layer, the brazing filler metal constituting the layer having the composition such that copper is added with at least phosphor to lower a melting point of the same relative to that of copper, thus producing the clad material.

Method for producing clad material, and clad material

A method of producing a clad sheet formed by joining a clad layer at least containing nickel, chromium, silicon, and phosphorus to a base material made of a stainless steel or a nickel-based alloy. A step of forming the clad layer includes contact-bonding a mixed powder to the base material, wherein an alloy powder that contains at least one selected from chromium, silicon, and phosphorus as components, and a nickel powder that functions as a binder to have the alloy powder be contact bonded to the base material are mixed in the mixed powder.

Clad sheet and method of producing same

In order to provide a brazing sheet having excellent workability, a powder of a brazing filler metal composition is obtained from a single type of powder or by mixing two or more powders to form the brazing filler metal composition. By powder roll compaction of the powder, the powder is formed into a sheet shape.

Brazing filter metal sheet and method for production thereof

A carbon powder inlet and a graphite powder collecting are oppositely arrange on a furnace body. At least a pair of electrodes are oppositely arranged in the furnace body with respect to a graphitizing area at an intermediate position between the inlet and the collecting port and are engaged with different timing.
