Method for producing wire and bar materials

Abstract

The invention relates to a method for producing wire and bar materials, which sequentially comprises the steps of smelting, secondary refining, square billet continuous casting, heavy forcing down, rolling and controlled cooling, and finished product collecting and coiling. The method adopts a heavy forcing down process to save the steps of casting blank stacking slow cooling, square billet downward delivery and square billet heating after the step of the square billet continuous casting, and organically compresses and combines a past steel plant with a past high-wire plant or bar material plant to form a short-flow production method of the wire and bar materials and greatly reduce the energy source consumption; besides, the production cost is far lower than that of the conventional long-flow process and is more lower than that of an overlong-flow process with secondary fire material formation, the benefit advantages are obvious, and the quality in producing high-carbon wire and bar materials is far better than that of the conventional art.

Description

technical field [0001] The invention relates to a production method of iron and steel materials, especially a production method of wire rods. Background technique [0002] Before the present invention, the production of wire and bar generally needs to go through the steps of electric furnace or converter smelting, secondary refining, billet continuous casting, billet stacking and slow cooling, billet delivery, billet heating, rolling and controlled cooling. Finished products, such a process route is a long-process production process route, which involves many processes. Generally, the steelmaking plant and the steel rolling plant are far away from each other, so continuous casting and rolling cannot be realized, and hot charging and hot delivery can be realized at most. Especially in the production of high-carbon steel and alloy steel wire and rod, although technical measures such as low-temperature casting, reduced casting speed, electromagnetic stirring of the mold, and li...

The disadvantage is that after secondary heating, it will cause greater energy consumption and environmental pollution, and the production cost is much higher than the traditional process.
