摘要:
Skin material of a clad material is composed of one or more layers, each layer of the skin materials is made of a metal different from the core material in their component compositions, and at least one layer of the skin material has a cast microstructure, when the skin material is superposed on either of one or both faces of the core material.
摘要:
A method for manufacturing a clad material composed of a core material and one or more skin materials which are superposed on either one or both faces of the core material, includes a clad material preparation process where an ingot for core material is manufactured by melting and casting a metal, and an ingot for skin material is manufactured by melting and casting a different metal for skin material, without hot rolling. The ingot for skin material is superposed as a skin material at a predetermined position of either one or both faces of the ingot for core material and the superposed material is hot-rolled to manufacture a clad material.

Equipment for manufacturing skin material of a clad material includes a casting apparatus which melts and mixes a metal for the skin material different from the core material in their component compositions, and casts the skin material; an ingot-cutting apparatus which cuts an ingot for skin material which is cast by the casting apparatus; and a conveying apparatus which conveys the ingot for skin material among each apparatus. The ingot-cutting apparatus is a slicing apparatus which slices the ingot for skin material into a predetermined thickness.

A method for manufacturing a clad material composed of a core material and one or more skin materials which are superposed on either one or both faces of the core material, includes a clad material preparation process where an ingot for core material is manufactured by dissolving and casting a metal, and an ingot for skin material is manufactured by dissolving and casting a different metal for skin material, without hot rolling. The ingot for skin material is superposed as a skin material at a predetermined position of either one or both faces of the ingot for core material and the superposed material is hot-rolled to manufacture a clad material.
摘要:
The present invention provides a method for manufacturing a clad material and the equipment for manufacturing the clad material, in which the productivity is excellent, the surface state and the flatness of the clad material can be readily controlled and the deterioration in adhesion rarely occurs in the clad material. The method for manufacturing the clad material composed of a core material and one or more skin materials which are superposed on either one or both faces of the core material includes: a clad material preparation process where an ingot for core material, which is manufactured by dissolving and casting a metal for core material in a core material preparation process, and an ingot for skin material, which is manufactured by dissolving and casting a metal for skin material different from the core material in their component composition, in a skin material preparation process, are prepared, respectively; a superposition process where the ingot for skin material is superposed as a skin material at a predetermined position of either one or both faces of the ingot for core material to manufacture a superposed material; and a clad hot-rolling process where the superposed material is hot-rolled to manufacture a clad material.

The present invention aims to provide hepatitis C virus inhibitors capable of inhibiting viral replication in hepatitis C virus-infected cells.The replication of hepatitis C virus can be inhibited and hepatitis C virus-infected cells can be specifically injured by specifically inhibiting BGT-1 or AKR1C1 involved in the replication of hepatitis C virus. Thus, viral inhibitors comprising a substance inhibiting BGT-1 or AKR1C1 are effective for the treatment of hepatitis C.
摘要:
An aluminum-base brazing alloy containing essentially up to 2 wt % of Cu, 0.01 to 0.08 wt % of Ti, and the balance of Al and unavoidable impurities, with or without at least one component selected from the group consisting of 0.01 to 0.5 wt % of Zr, 0.05 to 0.5 wt % of Mn and 0.05 to 0.5 wt % of Cr.
摘要:
Aluminum alloy composite materials for brazed heat exchangers are described, which comprise an Al core alloy essentially consisting of predetermined amounts of Si, Mg, Cu and at least one element selected from Mn, Cr and Zr, the balance being Al and inevitable impurities, and an Al alloy clad layer formed on one side of the core alloy which is in contact with an aqueous heat transfer medium. The clad layer has a thickness 3-20% based on the thickness of the composite material and a less-noble corrosion potential of 20-100 mV than the core alloy. A filler alloy may be formed on the other side of the core alloy.
