Abstract

The invention discloses a metal aerosol can, which is made of the following components: iron, ferrosilicon, copper block, zinc block, scrap steel, ferromanganese, ferrochromium, ferromolybdenum and ferrozirconium. The metamorphic treatment of molten iron has the function of refining and eliminating the harmful effects of impurity elements, eliminating the D-type graphite and E-type graphite generated by impurity elements on the tendency of molten iron to be supercooled, reducing the section sensitivity of castings with different section thicknesses, and effectively improving the matrix. The mechanical properties of the material, so that the metal aerosol can prepared from the base material has more excellent compression resistance, and the service life is greatly improved. The introduction of zirconium can not only improve the graphite morphology of the matrix material and improve the mechanical properties, but also neutralize the nitrogen content in the molten iron and reduce the probability of crack-like pores in the casting. The addition of chromium can reduce the amount of ferrochromium added in the furnace, change the dissolution and solidification characteristics of chromium in molten iron, and reduce the shrinkage tendency of the matrix material.

Description

technical field [0001] The invention relates to the technical field of aerosol cans, in particular to a metal aerosol can. Background technique [0002] The concept of aerosols originated from Lynde's 1862 proposal to prepare pressurized packaging with a saturated solution of gas. Until 1926, Norwegian chemical engineer Erik Rotheim used liquefied gas to prepare the prototype of modern aerosol. [0003] In 1943, Goodhue used dichlorodifluoromethane (trade name F12) as a propellant to prepare a portable insecticidal aerosol, which should be the most important progress in the development of aerosols. Insecticide aerosols were launched in 1947, when thick and heavy pressure-resistant containers were required. With the successful development of low-pressure propellants and low-pressure containers, the cost of aerosols decreased and developed rapidly. In the 1950s, aerosols were used for skin diseases, wounds, burns and local infections, and in 1955, they were used for respira...
