Abstract

The invention discloses steel low in price. The raw materials of the steel include carbon, silicon, manganese, cerium, phosphorus, titanium, molybdenum, iron and impurities. The steel comprises, by weight percentage, 0-0.22% of carbon, 0-0.35% of silicon, 0-0.03% of manganese, 0.32-0.45% of cerium, 1-1.45% of phosphorus, 0-0.055% of titanium, 0-0.045% of molybdenum, and the balance iron and impurities. According to a smelting process of the steel, iron is smelted into the steel in a top-blown converter. Specifically, the iron and waste steel are mixed and poured into the converter, and by introducing oxygen, the oxygen is combined with the carbon in the iron to form carbon monoxide, so that the carbon is taken away. In this way, the use performance of the steel low in price is not affected, and the steel has quite good machining performance and good material strength, is wide in application, can effectively lower the production cost for enterprises and factories, and is favored by customers.

Description

The steel that a kind of price is cheap
Technical field
The present invention relates to Steel material field, particularly relate to the steel that a kind of price is cheap.
Background technology
Steel are that steel ingot, steel billet or steel make required variously-shaped, size and the material of performance by pressure processing Material.Structural steel is a class of steel.Steel for building require have higher intensity, preferable plasticity at aspect of performance With toughness and good processing characteristics.Require there is good solderability, for work at low temperatures simultaneously for Welding Structure The steel construction made, it is desirable to steel can keep good toughness at low temperatures.For the structure worked under environment in the open, or have The structural requirement steel worked in the environment of evil erosion medium resistance have preferable rust-proofing ability.Present steel cost is high, can increase The production cost of enterprise, it is not easy to application.
Summary of the invention
The technical problem that present invention mainly solves is to provide the steel that a kind of price is cheap, can meet modern's need to steel Ask.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide the steel that a kind of price is cheap, institute The material composition stating steel includes carbon, silicon, manganese, cerium, phosphorus, titanium, molybdenum, ferrum and impurity, described steel by weight percentage, including former Material composition has: carbon≤0.22%, silicon≤0.35%, manganese≤0.03%, cerium 0.32-0.45%, phosphorus 1-1.45%, titanium≤0.055%, molybdenum≤ 0.045%, ferrum and impurity: surplus, ferrum is smelt steel in top-blown converter by the process for making of described steel, be specially by ferrum with Steel scrap mixes to be poured in stove, is passed through oxygen and makes oxygen be combined into carbon monoxide with the carbon in ferrum carbon ribbon is walked.
In a preferred embodiment of the present invention, described steel by weight percentage, including material composition have: carbon 0.11%, silicon 0.18%, 0.015%, cerium 0.41%, phosphorus 1.23%, titanium 0.035%, molybdenum 0.022%, ferrum and impurity: surplus.
In a preferred embodiment of the present invention, described in be passed through the technique of oxygen for being blown into oxygen stream.
In a preferred embodiment of the present invention, the described time made steel in top-blown converter is 45-60 minute.
The invention has the beneficial effects as follows: the steel that the price of the present invention is cheap, do not affect the serviceability that steel itself has, tool There are extraordinary processing characteristics and the preferable strength of materials, are widely used, it is possible to effectively reduce enterprise and the production cost of factory, Welcome by consumer.
