Rolling machine and the disadvantages of traditional cooling chillers application advantages

2020/10/09
Typically, calender equipment generally USES natural cooling and cooling, air cooling methods. But because of the above two ways are restricted by the form and field, so the heat exchange process is not perfect, the cooling effect is not ideal for calender. And application in calender cooling, cold water machine can keep calender of cooling water temperature is stable, and improve the life of the calender and coiling operation stability of the system.

this is due to the working medium in the system constantly circulating, status changes, the heat exchange with the outside world, makes into the cold water machine can rapid cooling water, to lower the water temperature, mix with water, achieve the balance of heat release and absorption of heat in the cooling water.

calender the disadvantages of traditional cooling: 1, the natural cooling way is to use external tank big enough to offset due to the heat generated by the metal rolling process. In the cooling process, due to the density of water with temperature changes and produce fluid circulation process, with the aid of this cycle take away heat, to achieve the cooling effect of calender. The equipment take up the space is larger, at the same time, the cooling effect is not ideal.

2, air cooler air as heat transfer medium is used for heat exchange, heat away through the air, so also called air cooler. In general, the wind of the cooler cooling effect mainly depends on its components the heat exchange area of the radiator and the air volume, simply: the same heat transfer area, the greater the air cooling effect, the better, the same air flow and the heat transfer area, the greater the heat dissipation effect is better.
