Definitions
- the present invention belongs to a seamless pipe manufacturing technique, and particularly relates to a method for manufacturing a high-strength and high-toughness seamless pipe.
- Patent Document 1 Republished Patent Publication W096Z12574
- Patent Document 2 Japanese Patent Laid-Open No. 8-311551
- Patent Document 3 Japanese Patent Laid-Open No. 2001-240913
- An object of the present invention is to provide a method of manufacturing a seamless pipe in a continuous process from a piercing and rolling process to a heat treatment.
- the present inventor has studied in detail the conventional techniques as shown in the above-mentioned Patent Documents 1 to 3, and found that the structure of the product manufactured in the continuous process is not sufficiently miniaturized. In other words, it has been found that a manufacturing method for refining the structure is indispensable for a seamless pipe manufactured in a continuous process. [0008] Based on the above findings, the present invention was completed by optimally selecting each condition from the piercing and rolling process to the heat treatment.
- the gist of the present invention is the following seamless pipe manufacturing method.
- the above-mentioned squeezing rolling process includes a piercing rolling process, a stretching rolling process, a constant diameter rolling process, a reheating process, a quenching process, and a tempering process, and the temperature of the seamless pipe is 600 ° C or higher and lower than 800 ° C.
- the process is terminated, and a seamless pipe having a temperature of 400 ° C or higher is charged into the reheating furnace through the reheating step, and reheated to a temperature not lower than the Ac transformation point and not higher than 1000 ° C.
- FIG. 1 is a diagram showing a line configuration for carrying out the method of the present invention. As shown in the figure, the billet furnace 1 to the straightening machine 8 are arranged on one continuous line. Each step of the method of the present invention will be described with reference to this figure.
- the hollow shell that has been pierced and rolled is rolled using a continuous stretch rolling mill 3 and a constant diameter rolling mill 4.
- continuous stretch rolling mills such as mandrel mills
- constant diameter rolling mills such as sizers and stress reducers.
- the reheating furnace is installed on one line, the temperature drop of the seamless pipe from the end of the constant diameter rolling process to the transition to re-caloric heat can be slightly suppressed.
- a heat insulation cover may be provided in the transport facility connecting the constant diameter rolling process and the reheating furnace to prevent the temperature of the seamless pipe from decreasing.
- the upper limit of 1000 ° C is the force that, when heated at a temperature higher than this, the crystal grains in the structure of the product become coarse and the toughness of the product after the quenching process decreases.
- the starting temperature of the quenching process is below the Ac transformation point.
- FIG. 1 is a diagram showing an example of an equipment line for carrying out the method of the present invention.
