Preparation device for high-strength corrosion-resistant alloy plate, and corrosion-resistant alloy plate thereof

Abstract

The invention discloses a preparation device for a high-strength corrosion-resistant alloy plate, and a corrosion-resistant alloy plate thereof. A limiting plate is welded at the top end of a sintering placement plate, and a shaping box is clamped at the side end of the limiting plate; an inner extrusion plate is placed at one end of the shaping box, and an extrusion spring is welded at one end of the inner extrusion plate; the outer side of the extrusion spring is sleeved with a double-layer protection sleeve; one end of the extrusion spring is spot-welded on an outer extrusion plate, and a cooling fan is installed at the top end of a sintering furnace; an exhaust pipe penetrates through the top end of an air collecting box, and an inlet-outlet pipe penetrates through the top end of an inlet-outlet box; the air inlet end of the inlet-outlet pipe is installed at the top end of the gas tank in a penetrating mode. Liquid-phase metal is extruded through the inner extrusion plate an the extrusion spring, and therefore the occupied space of molten metal is reduced; meanwhile, gas contained in liquid phases can be extruded during extrusion, and therefore the amount of the gas in the metal is reduced; the gas in the metal is exhausted through repeated pumping and inflating of the gas tank, and the influence of the gas on the metal in a solid-liquid state during sintering is reduced; and the quality and yield of the metal are guaranteed.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a high-strength corrosion-resistant alloy plate preparation device and its corrosion-resistant alloy plate. Background technique [0002] An alloy is a mixture of two or more chemical substances with metallic properties. It is generally obtained by fusing the components into a uniform liquid and then condensing it. The alloy is at least one of the following three types: Single-phase solid solutions, mixtures of many metal phases, and intermetallic compounds formed by metals are now generally used for alloy manufacturing by casting and sintering methods. [0003] However, when metals are sintered at present, due to the carbon contained in the metal, during sintering, the carbon and the oxygen produced by the reduction of oxides on the metal surface are combined to form carbon monoxide during sintering, resulting in a large number of bubbles in the metal sintering liquid. , the...

[0003] However, when metals are sintered at present, due to the carbon contained in the metal, during sintering, the carbon and the oxygen produced by the reduction of oxides on the metal surface are combined to form carbon monoxide during sintering, resulting in a large number of bubbles in the metal sintering liquid. , the gas produced will affect the vacuum environment in the sintering furnace, and at the same time, the bubbles will remain in the metal plate when the molten metal is cooled, resulting in a hollow inside the metal plate or pits on the outside, resulting in the scrapping of the metal plate, which is extremely Greatly affect the quality and production efficiency of the product
