Abstract
The core rod material is cobalt-based alloy, the phenomena that the service life of the core rod is short, and the inner wall of a pipe is cracked or even broken when copper and the copper alloy are used for rolling the pipe are overcome, and the cobalt-based alloy comprises the following elements in percentage by weight: 0.4 to 1.5 percent of C, 0.1 to 2.0 percent of Si, 0.1 to 2.0 percent of Mn, less than 2.0 percent of P, less than 2.0 percent of S, 23 to 30 percent of Cr, 5.0 to 20 percent of Ni, less than 5.0 percent of Fe, trace Mo and the balance of Co, and the alloy has excellent comprehensive properties of strength, abrasion resistance, oxidation resistance, thermal fatigue resistance, thermal shock resistance and the like, and is a core rod material with good rolling effect of copper and copper alloy.
Description
Technical field
The present invention relates to the alloy field, especially cobalt-base alloys.
Technical background
When utilizing three-roller planetary rolling mill to copper and copper alloy strand drawn and rolled tube, because the friction of the outer roll of pipe, the copper pipe temperature is elevated to more than 700 ℃, to being positioned at the plug of copper base endoporus, because be wrapped in copper pipe inside fully, its temperature also can reach more than 700 ℃, be subjected to the effect that roll pressure that passes over and complicated power such as twisting moment are simultaneously, can produce very big influence to pipe, as present the most frequently used mandrel material is CoCr28MoNi, undesirable because of performance own, tube wall surface is cracked, even cause fracture, had a strong impact on rolling quality, and each plug generally can only be rolling about 30 tons, and service life is short, the consumption that has strengthened mandrel material.Smooth in order to guarantee the tube rolling inner surface, do not crack, improve the service life of plug, just necessarily require mandrel material itself to have good performances such as high strength, wear-resistant, anti-oxidant, thermal fatigue resistance, heat shock resistance.
Summary of the invention
The purpose of this invention is to provide a kind of high comprehensive performance, to copper and the good three-roller planetary rolling mill mandrel material of copper-alloy pipe-material effect of rolling.
The invention provides a kind of cobalt-base alloys as mandrel material, be made up of following element, the percentage by weight of alloying element is as follows:
Carbon 0.4-1.5
Silicon 0.1-2.0
Manganese 0.1-2.0
Phosphorus＜2.0
Sulphur＜2.0
Chromium 23-30
Nickel 5.0-20
Iron＜5.0
The molybdenum trace
The cobalt surplus
By the cobalt-base alloys intensity height that said components is formed, instantaneous performance is good, and at 800 ℃-900 ℃, the alloy fracture stress difference can remain on 4kg/mm
2More than.Under long-term user mode, have good non-oxidizability, long service life, material grains is thinner, does not in use crack, and guarantees the slickness of copper pipe inner surface.Good mandrel material that so cobalt-base alloys of the present invention is a three-roller planetary rolling mill to be rolled copper and copper alloy strand.
The specific embodiment
Making profile in foundry furnace is columniform cobalt-base alloys, and the percentage by weight of forming each element of cobalt-base alloys is: C 0.4-1.5, Si 0.1-2.0, Mn 0.1-2.0, P＜2.0, S＜2.0, Cr 23-30, Ni 5.0-20, Fe＜5.0, Mo trace, Co surplus.
The case hardness HRC value of cobalt-base alloys of the present invention is greater than 35; When operating temperature during at 600 ℃-800 ℃, hot strength is greater than 40kgf/mm
2, plasticity is greater than 10%; In the time of 800 ℃-900 ℃, the fracture difference is greater than 4kg/mm
2, persistence is good under the high temperature; In 900 ℃ of air dielectrics, through 100 hours, rate of body weight gain was less than 0.1g/m
2-h; So when temperature was higher, antioxygenic property was better; Cast sturcture's crystal grain of alloy is 1 grade of crystal grain.
Claims (1)

Carbon 0.4-1.5
Silicon 0.1-2.0
Manganese 0.1-2.0
Phosphorus＜2.0
Sulphur＜2.0
Chromium 23-30
Nickel 5.0-20
Iron＜5.0
