Abstract
The invention provides a special mold steel material for an SPKA22400 high-energy spiral pressure machine, for both solving the problem that the production efficiency is low when conventional 5CrNiMo mold steel is used and effectively lowering the material cost of a mold. The special mold steel material for the SPKA22400 high-energy spiral pressure machine is characterized by comprising the following materials in percentage by weight: 0.50-0.60% of C, 0.70-1.00% of Mn, less than or equal to 0.40% of Si, 0.70-1.00% of Cr, 1.40-1.80% of Ni, 0.25-0.40% of Mo, 0.10-0.15% of V and the balance of Fe and inevitable impurities.
Description
Technical field
The present invention relates to Hot Work Tool Steel field, especially relate to large-scale die steel for hammer forging field, be specially a kind of particular manufacturing craft steel of the SPKA22400 of being applied to high power screw press.
Background technology
The traditional large-tonnage forging equipment of forge works is hydropress and forging hammer both at home and abroad, after the nineties, large-tonnage screw press starts to be widely used, SPKA22400 high power screw press is the First large-tonnage screw press that China introduces from Bohler company, also it is second in the world, the maximum hitting power 35500T of SPKA22400 high power screw press, specified hitting power 22400T, permit continuously hitting power 28000T, so its especially big hitting power is a huge test for moulding stock.
Domestic large-scale die steel for hammer forging generally adopts the 5CrNiMo steel that price is lower, but the heat resistance and the wear resistance that are 5CrNiMo steel are poor, and temper resistance is not high, its use temperature also should not be over 500 ℃ in addition, so in production process often there is " heap collapses " in mould, has a strong impact on production efficiency; 5CrNiMoV steel, 56CrNiMoV7 steel (German grade of steel) are external widely used forging die steel, and the thermostrength of these die steel is good, work-ing life is apparently higher than 5CrNiMo steel.Excessive quantitative analysis and research are done by China to this in the eighties in 20th century, and recommend 5CrNiMoV steel for large-scale, complicated heavy lift hammer forging die, but 5CrNiMoV or 56CrNiMoV7 price are relatively high, because large mould tonnage is larger, a set of maximum mould approaches 25 tons, so die cost is very high.
Summary of the invention
For the problems referred to above, the invention provides a kind of particular manufacturing craft steel of the SPKA22400 of being applied to high power screw press, when can solving the traditional 5CrNiMo die steel of employing, it produces the problem that generation efficiency is low, and can active mold material cost.
Its technical scheme is such, a kind of particular manufacturing craft steel that is applied to SPKA22400 high power screw press, it is characterized in that: the material that it comprises following weight percent: carbon (C) 0.50～0.60, manganese (Mn) 0.70～1.00, silicon (Si)≤0.40, chromium (Cr) 0.70～1.00, nickel (Ni) 1.40～1.80, molybdenum (Mo) 0.25～0.40, vanadium (V) 0.10～0.15, all the other are iron (Fe) and are inevitably mingled with.
Beneficial effect of the present invention is: its tempering resistance has improved more than 100 ℃ compared with 5CrNiMo steel, its over-all properties reaches the level of 5CrNiMoV steel, 56CrNiMoV7 steel, it uses normally in the production of SPKA22400 high power screw press, production efficiency is high, but its material cost significantly reduces than 5CrNiMoV steel, 56CrNiMoV7 steel, thereby can greatly reduce production costs.
