Fast cooling shaping casting mold of copper base catalyst alloy

Abstract

A rapid chilling shaping casting mold for a copper based catalyst alloy comprises a chill seat, a forming die casing graphite insulating cover opening and a fastening buckle. The forming die casing is combined mold composed of the left die casing and a right die casing. The combined mold is fixed by the fastening buckle. The cross-sectional shape of the forming die is a circular shape. The chill seat is disposed at the lower end of the forming die casing. A location pole corresponding to the inner cavity of the forming die casing is disposed at the upper end of the chill seat. Expansion clearance with a height of 1 / 10-1 / 5 of that of the forming die casing is disposed between the location pole outer circle and the forming die casing inner cavity. The graphite insulating cover opening is disposed at the upper end of the forming die cashing. By using the invented mold to cast the copper based catalyst alloy, a cooling rate of 150 DEG C / min and an up-down temperature gradient can be formed, thereby the melt metal can form columnar crystal growing directionally along the S100 crystallographic axis, so that micro region concentration gradient of Zn, Pb elements in the alloy is formed.

Description

Technical field: [0001] The invention relates to a copper-based catalyst alloy molding casting mold with anti-scaling function. Background technique: [0002] In the water treatment process of petroleum, chemical industry, electric power, papermaking, printing and dyeing, heating and other industries, water pipelines must be used. Water pipelines will produce scale during long-term high-temperature use, and the generation of scale will affect industrial production. The normal operation of the equipment will lead to the paralysis of the entire production system or cause major safety accidents such as equipment explosion. For this reason, after long-term experimental research, our unit has finally developed a copper-based catalyst alloy material with anti-scaling function. Formed along the S 100 The crystal axis is oriented to grow columnar crystals, and the Zn and Pb elements in the copper-based catalyst alloy produce micro-region concentration gradients. Using this casting...
