Production method of alloy plate

Abstract

The invention discloses a production method of an alloy plate, and belongs to the technical field of alloy plates. The production method comprises the following steps of (1) centrifugally casting an alloy tube blank; (2) mechanically processing the inner and outer walls of a hollow blank; (3) equally cutting the hollow blank to be arc plates along a longitudinal axis direction; (4) heating the preheated arc plates to 1180-1230 DEG C, and flattening the arc plates by using a rolling mill or a forging machine; and (5) hot rolling the flattened arc plates to be the alloy plate. According to the production method of the alloy plate, the alloy plate is produced by using a centrifugal casting technology; the metal use ratio is high; the production cost is low; the operation is simple; the equipment investment is small; the production efficiency is high; the performance after rolling is relatively high; use requirements can be met; and the production method is applicable to small scale production of the alloy plate.

Description

technical field [0001] The invention belongs to the technical field of alloy plates. Background technique [0002] At present, there are two ways to solidify the alloy liquid into a slab, one is the traditional die casting, and the other is the continuous casting developed later. The production process of the steel plate is roughly: "electric furnace smelting→refining→continuous casting\die casting→rolling→ Heat treatment→finishing and warehousing". The process of continuous steel casting is: the molten steel continuously passes through the water-cooled crystallizer, condenses into a hard shell, and then is continuously pulled out from the outlet below the crystallizer, cooled by spraying water, and cut into billets after being completely solidified. Continuous casting can maintain continuous production, high production efficiency, smooth slab surface, small amount of cleaning, high metal yield, and has been developed rapidly. However, continuous casting equipment is expens...

Problems solved by technology

Continuous casting can maintain continuous production, high production efficiency, smooth slab surface, small amount of cleaning, high metal yield, and has been developed rapidly. However, continuous casting equipment is expensive and suitable for mass production, mainly for the production of carbon steel and ordinary stainless steel billets

For small batch production, die-casting is generally used to produce slabs, but traditional die-casting requires molds to be cast each time, cooling and then demoulding, which occupies a large area, takes a long time, and has a low yield, and die-casting needs to be cleaned. The metal utilization rate is low, resulting in a large waste of metal resources

For materials that require a large compression ratio, such as 0Cr17Ni12Mo2, 00Cr19Ni10, 00Cr19Ni13Mo3, 0Cr18Ni12Mo2Cu2, limited by the size of the section, the internal grains of the produced billet are coarse, shrinkage is much, the structure is poor, the performance after rolling is low, and it cannot be used.
