preparation example Construction

[0017] A method for preparing a bimetal composite steel bar, the preparation method comprising the following steps:

[0018] A. First select the steel billets, manganese metal billets, titanium metal billets and nickel metal billets, and then inspect the steel metal billets, manganese metal billets, titanium metal billets and nickel metal billets, and process them only after passing the inspection;

[0019] B. Then add the qualified steel metal billet, manganese metal billet, titanium metal billet, nickel metal billet and carbon into the melting furnace in proportion to melt, and then make the molten mixed metal into a billet with a length of 6 to 12 meters;

[0020] C, then the billet obtained in the step B is twisted and rolled, and the thickness of the steel bar can be used to adjust the rolling as required;

[0021] D, then carry out water cooling to the high-temperature steel bar that rolling is finished;

[0022] E. Finally, the length of the steel bar can be cut by the...

Abstract

The invention discloses a preparation method of a bimetal composite reinforcing steel bar. The preparation method comprises the following steps: A, firstly, a steel metal blank, a manganese metal blank, a titanium metal blank and a nickel metal blank are selected, then the steel metal blank, the manganese metal blank, the titanium metal blank and the nickel metal blank are inspected, and processing is carried out after the steel metal blank, the manganese metal blank, the titanium metal blank and the nickel metal blank are inspected to be qualified; and B, the steel metal blank, the manganese metal blank, the titanium metal blank, the nickel metal blank and carbon which are qualified through inspection are added into a smelting furnace according to the proportion to be melted, and then the melted mixed metal liquid is prepared into a blank with the length of 6-12 m. By adding high-strength steel metal, manganese metal, titanium metal, nickel metal and carbon, the advantage of improving the strength of the reinforcing steel bar is achieved, so that when the reinforcing steel bar is processed, high-strength metal can be added, the strength of the reinforcing steel bar is effectively enhanced, the reinforcing steel bar is prevented from being broken during use, the service life of the reinforcing steel bar is prolonged, and meanwhile, a building concrete framework is prevented from being easily broken.

Description

technical field [0001] The invention relates to the technical field of steel bar processing, in particular to a method for preparing bimetallic composite steel bars. Background technique [0002] Steel bar refers to steel for reinforced concrete and prestressed reinforced concrete. The straight or coiled steel used for reinforcement is divided into two types: smooth round steel bar and deformed steel bar, and the delivery state is straight bar and coiled round. [0003] The current existing steel bar preparation method has the following disadvantages: the existing steel bar preparation method only has one material, steel, and its strength is not high, which causes the steel bar to break easily when it is used, and causes the building concrete skeleton to break easily, which cannot meet the requirements of the application. user needs. Contents of the invention [0004] The purpose of the present invention is to provide a method for preparing bimetallic composite steel bar...
