Abstract
The invention discloses multi-component brazed steel and a preparation method thereof. The preparation method mainly comprises the following steps: compositional raw materials C, Si, Zn, Cu, Mn, Cr, Ni, Mo, Ti, Al and Fe are evenly mixed according to a certain weight percentage; and the mixture is hot-rolled, air-cooled and then tampered at a temperature of 200 to 600 DEG C to adjust the hardness, and then the multi-component brazed steel is obtained. The preparation method disclosed by the invention is simple and requires a low cost; and by adding the micro alloy elements of Ti and Al, the manufactured brazed steel has the characteristics of high strength, high toughness and long service life.
Description
Technical field
The present invention relates to a kind of polycomponent rock-drill steel and preparation method thereof, belong to the steel alloy technical field.
Background technology
In the rock drilling process, drill steel plays a part to transmit energy between rock drilling machinery and rock, and drill steel bears huge impact, torsional load; And the corrosion of outside deterioration and endoporus stress, working conditions is very harsh, and the foot of a hill or mountain the development of high-power rock drilling machinery; Need the rock drill drill steel of high life especially, just high performance rock-drill steel need be provided, mostly the heavy rock-drill steel that uses at present is low-carbon (LC) Cr-Ni steel alloy; Thermal treatment process such as the production needs of this steel alloy are annealed, carburizing, quenching, tempering, ME is complicated, and the technology circuit is longer; Cost is high, and unstable product quality influences the production efficiency of rock drilling machinery.
Summary of the invention
For deficiency and the defective of alleviating prior art; The object of the present invention is to provide a kind of polycomponent rock-drill steel and preparation method thereof, preparation method of the present invention is simple, and cost is low; Added Ti and Al microalloy element, the rock-drill steel that makes has HS, toughness height, long characteristics of life-span.
Adopt technical scheme of the present invention to achieve these goals:
The polycomponent rock-drill steel; The weight percent that it is characterized in that its constitutive material is: C 0.35-0.45%, Si0.85-2.30%, Zn 0.45-0.85%, Cu 0.65-1.35%, Mn 0.75-1.30%, Cr 0.35-0.95%, Ni 1.25-3.35%, Mo 0.10-1.00%, Ti 0.05-0.08%, Al 0.05-0.17%, remaining is Fe.
The preparation method of described polycomponent rock-drill steel; It is characterized in that comprising: the weight percent by constitutive material takes by weighing each raw material, mixes air cooling after hot rolling; Adjust hardness to 40-45HRC through 200-600 ℃ of temperature tempering again, make the polycomponent rock-drill steel.
Beneficial effect of the present invention:
Preparing method of the present invention is simple, and cost is low, has added Ti and Al microalloy element, and the rock-drill steel that makes has HS, toughness height, long characteristics of life-span.
