Packaging steel strip galvanized rising temperature how to control

Packaging steel strip galvanized raised temperature how to control the technology specification is as follows: 1. Zinc liquid need to heat up, want to continuously supply in the full heat of the process of temperature rise, may not be continuous in the middle. 2. In the process of heating up for catalpa liquid agitation, in order to make the whole uniform zinc temperature rise. 3. In the process of heating up, it is better to stop operation, in order to reduce the heat loss in the heating process. 4. Heating supply by hot board more than normal heating, to shorten the heating time. 5. When heating, zinc liquid liquid surface heat preservation measures should be taken, to reduce the heat to the air of the loss. 6. Cooling pressure fire in time, when you stop heating. 7. To make a fast cooling speed can be met. Blow a cold wind over to zinc liquid level Can also be added in the zinc liquid zinc block. 8. If you need to cool the amplitude is very big, can be scooped out part of the liquid zinc, then add the zinc block, and stir the zinc liquid, make the blocks of zinc in zinc liquid homogeneous melt. 9. Zinc liquid with a thermocouple temperature monitoring. But should pay attention to, no matter which kind of thermocouple, long-term in liquid zinc, will be dissolved liquid zinc corrosion. So, thermocouple to use high temperature resistant, and react with liquid zinc is not ceramic or glass tube to protect it.
