Problems solved by technology

[0002] In the past, glass tin baths were usually severely corroded due to unreasonable materials. Due to the high temperature of the glass liquid, a large amount of heat was generated, so the tin baths had a short life and needed to be replaced continuously, which stopped production and caused Huge loss of silence. At the same time, the tin bath is made of steel, which is of high quality. It is inconvenient for installation and maintenance, and the cost is still high. Therefore, the consumables are serious and the economic benefits are not good. Some companies have improved this steel tin bath. That is, after the tin bath is processed, aluminum oxide is sprayed on its instant noodles. Although the corrosiveness has been improved, the economic benefits have not been reduced in material application, and it is still difficult to overhaul and install, and there are still complex processes, high cost and poor quality. overweight problem,

Abstract

The invention discloses a machining forming manufacturing method for a glass tin bath made of 5Cr2NiMnVSi magnesium alloy and belongs to the technical field of machinery manufacturing. The machining forming manufacturing method for the glass tin bath is achieved through the following processes of blank casting, de-stressing, machining, quenching and high-temperature tempering, polishing and anticorrosion rust-proof treatment. According to the glass tin bath prepared through the manufacturing method, machining is easy, the structure is more reasonable, and the corrosion resistance and the oxidation resistance are improved greatly; the mechanical property is good, the service life is longer, the sealing performance is good, and the service life of the glass tin bath is further prolonged; the glass tin bath is suitable for high-speed and low-speed textile machinery, stable in work and high in reliability.

Description

technical field [0001] The method belongs to the technical field of mechanical manufacturing, and relates to a Cr2NiMnVSi magnesium alloy and a glass tin bath thereof. In particular, a method for processing and forming a glass tin bath made of 5Cr2NiMnVSi magnesium alloy material.
