真空感应炉水乙二醇替换无水脂肪酸酯液压油研究

Research on Replacing Anhydrous Fatty Acid Ester Hydraulic Oil with Water Glycol for Vacuum Induction Melting Furnace

真空感应炉翻炉液压系统液压介质原设计使用水乙二醇,含有40%~45%水,炉内翻炉液压缸一旦渗油,真空度无法保证,合成脂肪酸酯无水阻燃介质是一种环保液压油,采用合成脂肪酸酯替换水乙二醇,既可以阻燃、安全环保又可以保证真空度,避免真空波动影响产品质量,通过在普通国产电渣炉换油试验,3次检测结果证明水乙二醇可以用脂肪酸酯无水阻燃替换,利用检修时间对真空感应炉进行换油,生产后运行良好,防止液压系统漏油造成真空波动进而影响生产和产品质量。

The hydraulic medium of the hydraulic system of the vacuum induction melting furnace tilting was originally designed to use water glycol,containing 40%~45%water.Once the hydraulic cylinder for tilting leaks,the vacuum parameters cannot be guaranteed.The anhydrous fatty acid ester is a kind of environmental anhydrous flame retardant hydraulic oil.The anhydrous fatty acid esters is used to replace water glycol,which can be flame-retardant,safe and environmental,and can ensure the vacuum parameters,and avoid vacuum fluctuations affecting product quality.It has passed the oil change test in ordinary domestic ESR furnaces.The test results proved that water glycol can be replaced with anhydrous fatty acid ester anhydrous flame retardant by 3 times inspection results.The hydraulic oil of the vacuum induction melting furnace was replaced during the maintenance time.It works well since it is put in production.It can prevent the hydraulic system from leaking and avoiding vacuum fluctuations which can cause to affect production and product quality.
