Description
Technical field
The present invention relates to a kind of medium carbon steel steel-smelting production process method,.
Background technology
The main task of steel-making is the prescription by institute's steelmaking kind, and in adjustment steel, carbon and alloying element content are to regulation model
Within enclosing, and the content of the impurity such as P, S, H, O, N is made to be down under Permissible limit.Steelmaking process substantially one aoxidized
Journey, carbon superfluous in furnace charge is oxidized, burns into the effusion of CO gas, and other Si, P, Mn etc. enter in slag after aoxidizing.Middle carbon
Carbon content of steel is higher, and the difficulty of smelting and rolling is relatively big, when employing steel scrap is raw material, is extremely difficult to the requirement of 60 steel.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that a kind of medium carbon steel steel-smelting production process side
Method.
The purpose of the present invention implements by the following technical programs:
A kind of medium carbon steel steel-smelting production process method, including melting, continuous casting, rolling,
In steel raw material used, C content is 0.5～0.8%, Mn%:0.80～1.30, Cr≤0.3%, Ni≤0.40%, and Cu≤
0.45%, Si≤0.50%, all≤0.035%, final every weight of acquisition is the medium carbon steel steel bar of 35kg for S, P.
Specifically smelting technology and parameter are:
Add steel raw material, melting down after add pig up, electric current should be increased after adding the pig iron, be allowed to electromagnetic agitation homogenization,
Whole chemical composition meets following requirement:
C%:0.6～0.7, Si%:0.2～0.4, Mn%:0.70～0.80, Cr≤0.25%, Ni≤0.35%, Cu≤0.35%,
S%:＜ 0.035, P%:＜ 0.035, remaining is Fe, percentage；
Deoxidation uses secondary deoxidation according to steel scrap degree of oxidation, and secondary deoxidation aluminum is carried out in ladle；
Tapping temperature ensures that continuous casting is opened and waters temperature at 1600～1800 degree.
Described rolling mill practice and parameter be:
Firing rate≤30mm/h, heating-up temperature is 1300-1420 DEG C, and for preventing decarburization, the high-temperature region time of staying is less than 0.7
Hour, use reducing atmosphere during heating；
The preparation of roll: frame band steel roller the 5th hole, discharging 60*88, two frames use Li-Ping-vertical hole system.
One medium carbon steel steel-smelting production process method of the present invention, employing steel scrap is raw material, by adjusting the specific aim of technique
Whole and change near, the mechanical property of gained medium carbon steel has obtained obvious improvement.Concrete mechanical property sees following table:
