Abstract

Edit 12/04/2017 Provide a method For cooling steel strips In the glaze kiln Zinc annealed. Method is used by atomization cooling. On the steel bar In the cooling area Of kiln annealed zinc coating And can be achieved in both the yield. The cooling method consists of with a set of adjustable chiller. To rise above In the direction through the sheet Of the refrigeration unit, spraying the aerosol into the steel bar that passes through the Refrigeration set In the form that Amount of aerosol That sprayed to the steel bar Passing by Edge cooler unit in the width direction Of the steel bar is less than in the center part; With the mist set provided at least On the next side down In the direction through the sheet Of the chiller unit, suction is the least part of the aerosol sprayed to the steel strip; And cooling the steel strip At speed through the sheet In such a way that during the period between the start and end of cooling the steel strip, the temperature of the steel strip is within the temperature range. Of the boiling point of the film And the temperature of the edge in the directional width of the steel strip is equal to or higher than the temperature of the center. At least in the district 2/3 or more from the north side up. In the direction through the sheet Of the total cooling length of the refrigeration unit ----------------------- Provide a Method For cooling steel strips In the glaze kiln Zinc annealed. Method is used by atomization cooling. On the steel bar In the cooling area Of kiln annealed zinc coating And can be achieved in both yield rates. Refrigeration methods include: with adjustable chiller set. To rise above In the direction through the sheet Of the refrigeration unit, spraying the aerosol into the steel bar that passes through the Refrigeration set In the form that Amount of aerosol That sprayed to the steel bar Passing by Edge cooler unit in the width direction Of the steel bar is less than in the center part; With the mist set provided at least On the next side down In the direction through the sheet Of the chiller unit, suction is the least part of the aerosol sprayed to the steel strip; And cooling the steel strip At speed through the sheet In such a way that during the period between the beginning and the end of cooling the strip, the temperature of the strip is within the temperature range. Of the boiling point of the film And the temperature of the edge in the directional width of the steel strip is equal to or higher than the temperature of the center. At least in the district 2/3 or more from the north side up. In the direction through the sheet Of the total cooling length of the refrigeration unit Illustration illustrating Figure 1:
