Metal silk screen used for printing

Abstract

The invention discloses a metal silk screen used for printing. The raw materials of steel wires used for weaving the silk screen comprise the following effective components in percentage by weight: not more than 0.09% of C, not more than 0.30% of Si, not more than 0.80% of Mn, not more than 0.020% of P, not more than 0.005% of S, 20.0-22.0% of Cr, 10.5-12.5% of Ni, 0.05-0.12% of N, 0.05-0.10% of Nb and the balance of Fe and inevitable impurities. The metal silk screen provided by the invention can be directly produced by an existing wire drawing production method and an existing silk screen weaving method, and once rolling treatment is carried out after weaving shaping of the silk screen; and once shaping can be realized during wire drawing, wire breakage seldom emerges, the strength and hardness of the silk screen are improved, and the service life of the metal silk screen is prolonged.

Description

technical field [0001] The invention relates to a screen, in particular to a wire screen made of a new material and used in the printing industry. Background technique [0002] Wire mesh is widely used in various fields of industry and agriculture. Industrial wire mesh such as industrial filtration, screening, vibrating screen, road construction, site fence, craft mesh, etc.; civilian use such as grain processing, window gauze, etc.; in addition, wire mesh is also used in the printing industry. And the quality and precision requirements of the wire mesh in the printing industry are far greater than those of other industries. The wire mesh used in the printing industry needs to be produced in a dust-free workshop, and the flying dust will affect its quality. The wire diameter of the printing wire mesh can be as thin as 0.01mm or less, and the general material is generally 304 stainless steel (the national standard steel grade is 06Cr19Ni10), but although this material has g...

AI Technical Summary

Problems solved by technology

Although the strength of 304N stainless steel has increased, its elongation has also decreased. When drawing steel wires with general diameters, the reduction in elongation is not obvious, that is, it does not affect the drawing performance of general stainless steel wires, but when When the steel wire is as thin as 0.01mm, it is very easy to break the wire, which makes the wire drawing production impossible.

Therefore, the steel wire used in the production of ultra-fine printing wire mesh can only rely on imported steel wire from countries with a high level of industrial processing
