In-situ reaction precipitation manufacture device and process of lotus-root-shaped porous metal material

Abstract

本发明涉及一种藕状多孔金属材料的原位反应析出制备装置及工艺。该工艺过程是:在大气氛围的条件下,在铸模内壁上涂覆含水涂层,然后将熔化的金属液倾倒入铸模中,通过定向凝固,制备出具有高孔隙率、气孔大小可控、气孔长且直的藕状多孔金属材料。该装置的组成主要包括:熔炼炉、塞棒及控制系统、温度测量与控制系统、导流管、结晶器与冷却系统、铸模与固定装置等。本发明克服了“加压溶解析出法”的缺点,无须在高压氢气等高压气氛下生产,安全性好;操作简单,浇铸过程具有可视性;提出了一种结构简单、投资较少、操作简便的藕状多孔金属制备装置,可降低生产成本,实现制备过程的高效率和连续化。
The invention relates to an in-situ reaction precipitation manufacture device and process of a lotus-root-shaped porous metal material. The process comprises the steps of coating a water-containing coating on an inner wall of a casting mould under the atmosphere condition, pouring molten metal liquid into the casting mould and manufacturing the lotus-root-shaped porous metal material with high porosity, controllable pore size and long and straight pores through directional solidification. The in-situ reaction precipitation manufacture device mainly comprises a smelting furnace, a stopper rod and control system, a temperature measurement and control system, a guiding pipe, a crystallizer and cooling system, a casting mould and fixing device and the like. The shortcomings of a 'pressurized dissolving precipitation method' are overcome, production under high-pressure hydrogen and other high-pressure atmospheres is not needed, and the safety is good. The operation is simple, and the casting process is visible. The lotus-root-shaped porous metal material manufacture device is simple in structure, few in investment and simple and convenient to operate, the production cost can be reduced, and high efficiency and continuity of the manufacture process are achieved.
