Problems solved by technology

In the past, the chromium and nickel alloys that needed to be added were not easy to process in the production of these steel types, especially the nickel plate, which was very difficult to cut. During steelmaking, scrap steel had to be added into the converter together with the addition of scrap steel. To supplement molten iron and re-smelt steel, a new type of high-strength alloy steel has appeared in order to improve production efficiency. A layer of nickel-chromium material is compounded on the outside of the steel-based material, but the preparation process is quite strict. When the standard is met, it is easy to have holes, disconnection, etc., which will eventually affect the quality of the product

Embodiment Construction

[0014] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment comprises a steel element 1, the inside of which is provided with a closed hollow steel mold 2, and the outer surface of steel element 1 is provided with an alloy layer 3; the appearance of said hollow steel mold 2 is similar to that of steel The shapes of the elements 1 correspond to each other; the steel elements 1 are ordinary steel.

[0015] The production method of above-mentioned steel base alloy composite part is:

[0016] Water glass and quartz sand are used for pressure injection inside the production mold to make a mold that meets the specifications. The alloy layer 2 is coated on the inner surface of the mold, and the hollow steel mold 2 is placed in the cavity of the mold, and then the molten steel element 1 is placed The mixed raw material liquid is poured into the mould, the raw material liquid covers the hollow steel mold, and after cooling, a steel element 1 ...

Abstract

The invention belongs to the technical field of alloy for steel, and particularly discloses a steel-based alloy composite piece. The steel-based alloy composite piece comprises a steel element, and is characterized in that a closed hollow steel mould is arranged inside the steel element, and an alloy layer is arranged on the outer surface of the steel element. The steel-based alloy composite piece is structure in structure, convenient to use, reasonable in design, and flexible in application, the adhering effect of the alloy layer is good, phenomena of foaming or separation is unlikely to occur, the production cost is low, and the steel-based alloy composite piece is suitable for wide popularization and application.

Description

(1) Technical field [0001] The invention belongs to the technical field of steel alloys, in particular to a steel-based alloy composite part. (2) Background technology [0002] With the rapid development of the iron and steel industry, the demand for stainless steel, alloy steel and special steel in all walks of life is increasing, and the quality requirements are getting higher and higher. In the past, the chromium and nickel alloys that needed to be added were not easy to process in the production of these steel types, especially the nickel plate, which was very difficult to cut. During steelmaking, scrap steel had to be added into the converter together with the addition of scrap steel. To supplement molten iron and re-smelt steel, a new type of high-strength alloy steel has appeared in order to improve production efficiency. A layer of nickel-chromium material is compounded on the outside of the steel-based material, but the preparation process is quite strict. When...
