Abstract
The invention discloses steel capable of resisting fire effectively. The steel is prepared from, by weight, smaller than or equal to 0.15% of carbon, smaller than or equal to 0.48% of silicon, 0.3-0.6% of manganese, smaller than or equal to 0.025% of phosphorus, 0.45-0.65% of nickel, 4-6.5% of chromium and the balance iron and impurities. A process for making the steel comprises the steps of placing a raw steel material into a roughing mill to obtain a rough rolling material through head and tail cutting, and conducting milling on the rough rolling material with a finishing mill to obtain the final material. In this way, the steel does not deform under fire or high temperature, the usability of the steel can be effectively maintained, heat insulation effect is good, fire spreading and smoke diffusion can be effectively prevented, and practicality is quite high.
Description
Technical field
The present invention relates to Steel material field, particularly relating to one can effective fireproof steel.
Background technology
Steel are widely used, various in style.The raw material producing steel is steel, and the source of steel is iron ore, i.e. ferrum element Fe existence form in nature.Ferrum purely is non-existent in nature, and iron ore is broadly divided into magnetic iron ore, bloodstone, three kinds of limonite, and these are all the oxides of ferrum, and difference is their mode of oxidizing.Iron-holder in iron ore is the highest more good, in theory the most high Fe contained about 72% in iron ore, iron-holder 60% referred above to high-grad iron ore deposit.Existing steel often can be used in the place being susceptible to fire, and common steel can not make it the most heat insulation.
Summary of the invention
The technical problem that present invention mainly solves be to provide one can effective fireproof steel, modern's demand to steel can be met.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide the one can effective fireproof steel, the material composition of described steel includes carbon, silicon, manganese, phosphorus, nickel, chromium, ferrum and impurity, described steel is by weight percentage, including material composition have: carbon≤0.15%, silicon≤0.48%, manganese 0.3-0.6%, phosphorus≤0.025%, nickel 0.45-0.65%, chromium 4-6.5%, ferrum and impurity: surplus, the process for making of described steel includes steel raw material is put into roughing mill, crop through described roughing mill, tail operation obtains roughing material, described roughing material obtains whole material through finishing mill rolling.
In a preferred embodiment of the present invention, described steel by weight percentage, including material composition have: carbon 0.07%, silicon 0.24%, manganese 0.5%, phosphorus 0.013%, nickel 0.55%, chromium 5.6%, ferrum and impurity: surplus.
In a preferred embodiment of the present invention, the operation of described roughing mill and described finishing mill is by computer-controlled.
In a preferred embodiment of the present invention, the material through described finishing mill obtains whole material through section cooling again.
The invention has the beneficial effects as follows: the present invention can effective fireproof steel, will not deform in the case of meeting fire high temperature, it is possible to effective keep its usability, good heat-insulation effect, it is possible to effectively stop that fire spreading, flue gas spread, there is extraordinary practicality.
