Resumo

THE OBSTACLES THAT MUST BE OVERCOME THE MICROBIO CONTROL IN DIRECT CONTACT SYSTEMS, PARTICULARLY IN CONTINUOUS CASTING AND ROLLING PROCESSES, ARE DISCUSSED IN THE STUDY. EFFECTIVE CHEMICAL CONDITIONING IS HAMPERED BY OILS, SCALE, HIGH TEMPERATURES, AND DIRECT CONTACT. TO SOLVE THESE ISSUES, PURATE MAKES EXCELLENT USE OF CHLORINE DIOXIDE AS A SUPERIOR SUBSTITUTE TO CONVENTIONAL BIOCIDES. ITS ADVANTAGES INCLUDE LOW CHLORIDE GENERATION, BIOFILM ERADICATION, NO HAZARDOUS CHEMICAL CREATION, QUICK DISINFECTION, BROAD PH RANGE EFFECTIVENESS, LOW CORROSIVE POTENTIAL, AND COMPATIBILITY WITH CONDITIONING AGENTS. PURATE TECHNOLOGY USES A PROPRIETARY PROCESS THAT INCLUDES SODIUM CHLORATE, HYDROGEN PEROXIDE, AND SULFURIC ACID TO PRODUCE CHLORINE DIOXIDE. OVERALL, THE USE OF CHLORINE DIOXIDE IN PURATE TECHNOLOGY WITH DIRECT CONTACT SYSTEMS, PARTICULARLY IN CONTINUOUS CASTING AND ROLLING MILLS, DEMONSTRATES ITS EFFECTIVENESS AS A CHEMICAL CONDITIONING METHOD, BEING ABLE TO REDUCE THE CHLORIDE CONTENT IN THE WATER OF THE SPRAY SYSTEM BY 39%, REDUCING THE CORROSION RATE OF THE SYSTEM BY 37.6%

The obstacles that must be overcome the microbio control in direct contact systems, particularly in continuous casting and rolling processes, are discussed in the study. Effective chemical conditioning is hampered by oils, scale, high temperatures, and direct contact. To solve these issues, Purate makes excellent use of chlorine dioxide as a superior substitute to conventional biocides. Its advantages include low chloride generation, biofilm eradication, no hazardous chemical creation, quick disinfection, broad pH range effectiveness, low corrosive potential, and compatibility with conditioning agents. Purate technology uses a proprietary process that includes sodium chlorate, hydrogen peroxide, and sulfuric acid to produce chlorine dioxide. Overall, the use of chlorine dioxide in Purate technology with direct contact systems, particularly in continuous casting and rolling mills, demonstrates its effectiveness as a chemical conditioning method, being able to reduce the chloride content in the water of the spray system by 39%, reducing the corrosion rate of the system by 37.6%
