Abstract

The invention discloses an easily-cut metal pipe. The easily-cut metal pipe is formed by processing seven components of iron, phosphate, sulfur, bismuth, lead, selenium and carbon, wherein the weight percentages of the components of the easily-cut metal pipe are as follows: 90.9-95.6% of the iron, 0.3-1.2% of the phosphate, 0.2-0.9% of the sulfur, 1.5-2.3% of the bismuth, 1.8-2.7% of the lead, 0.2-0.7% of the selenium and 0.4-1.3% of the carbon. Through the addition of the phosphate, the sulfur, the bismuth, the lead, the selenium and other components into an iron billet, the easily-cut performance of the manufactured easily-cut metal pipe can be greatly improved, thus facilitating the cutting of the metal pipe; meanwhile the easily-cut metal pipe has the characteristics of high hardness and strength, high mechanical strength and long service life.

Description

A kind of easy cutting metal pipe

Technical field

The present invention relates to metal products, be specifically related to a kind of easy cutting metal pipe.

Background technology

At present, the ferrous products had on market in use tends to occur various defects, as ferrous products in the course of processing, because the cutting of ferrous products is unstable, cause when cutting can not be intact ferrous products is carried out to perfect cutting, cause the complete ferrous products quality of cutting of ferrous products not pass a test, result of use is poor, and work-ing life is short.In addition, existing ferrous products also exists that intensity and hardness are not high, the situation of bad mechanical strength, and various situations cause the use of ferrous products to be limited by very large.

Summary of the invention

The object of the present invention is to provide that a kind of free cutting property is high, hardness and intensity is high, physical strength large, the easy cutting metal pipe of long service life.

Technical scheme of the present invention is, a kind of easy cutting metal pipe, the above seven kinds of compositions of described easy cutting metal Guan Youtie, phosphorus, sulphur, bismuth, lead, selenium and carbon are made through processing treatment, in described easy cutting metal pipe, the shared weight percent of each composition is respectively: described iron accounts for 90.9%-95.6%, described phosphorus accounts for 0.3%-1.2%, described sulphur accounts for 0.2%-0.9%, described bismuth accounts for 1.5%-2.3%, described lead accounts for 1.8%-2.7%, described selenium accounts for 0.2%-0.7%, and described carbon accounts for 0.4%-1.3%.

In a preferred embodiment of the present invention, in described easy cutting metal pipe, the shared weight percent of each composition is specially: described iron accounts for 91.5%, described phosphorus accounts for 1.1%, described sulphur accounts for 0.8%, described bismuth accounts for 2.2%, described lead accounts for 2.6%, and described selenium accounts for 0.6%, and described carbon accounts for 1.2%.

In a preferred embodiment of the present invention, in described easy cutting metal pipe, the shared weight percent of each composition is specially: described iron accounts for 95%, and described phosphorus accounts for 0.4%, described sulphur accounts for 0.3%, and described bismuth accounts for 1.6%, and described lead accounts for 1.9%, described selenium accounts for 0.3%, and described carbon accounts for 0.5%.

Of the present invention is a kind of easy cutting metal pipe, this easy cutting metal pipe by adding the compositions such as phosphorus, sulphur, bismuth, lead, selenium in the baslled iron material, can be so that the free cutting property of the metal tube made improves, be convenient to the cutting of metal tube, simultaneously, also make metal tube there is hardness and intensity is high, physical strength is large, the characteristics of long service life.

Embodiment

Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.

Of the present invention is a kind of easy cutting metal pipe, the above seven kinds of compositions of described easy cutting metal Guan Youtie, phosphorus, sulphur, bismuth, lead, selenium and carbon are made through processing treatment, in described easy cutting metal pipe, the shared weight percent of each composition is respectively: described iron accounts for 90.9%-95.6%, described phosphorus accounts for 0.3%-1.2%, described sulphur accounts for 0.2%-0.9%, and described bismuth accounts for 1.5%-2.3%, and described lead accounts for 1.8%-2.7%, described selenium accounts for 0.2%-0.7%, and described carbon accounts for 0.4%-1.3%.

Further, in described easy cutting metal pipe, the shared weight percent of each composition is specially: described iron accounts for 91.5%, and described phosphorus accounts for 1.1%, described sulphur accounts for 0.8%, and described bismuth accounts for 2.2%, and described lead accounts for 2.6%, described selenium accounts for 0.6%, and described carbon accounts for 1.2%.

Further, in described easy cutting metal pipe, the shared weight percent of each composition is specially: described iron accounts for 95%, and described phosphorus accounts for 0.4%, described sulphur accounts for 0.3%, and described bismuth accounts for 1.6%, and described lead accounts for 1.9%, described selenium accounts for 0.3%, and described carbon accounts for 0.5%.

Carry out proportioning by each composition Different Weight per-cent, make the product performance that obtain just differ.

The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
