Packaging steel strip factory packaged with the function of production cooling device profile

Packaging packaging steel strip manufacturer with production cooling device function introduction in order to get the size stability of the products, to the nose section at the end of the homogenization of the host, it is very important to control the temperature of the lower, lower polymer easy to keep the shape of the extrudate temperature, easy to cooling. The products after the nose extrusion cooling, generally adopts water cooling. By mouth die extrusion plate belt into the cooling water tank, should pass 10 - 20 cm long air cooling. Material in homogenization and the first class under the action of high temperature, the viscous flow, 洚 in air temperature, with traction speed into the water cooling tank, cooling water temperature in the 40 - general requirements Around 60 ℃, the lower the temperature, the faster the crystal materials, molecular weight loss is less, forming the faster, but the low temperature will make the material a sharp crystal, forming a nasty, products appear ripple and flow. Water temperature is too high, make the material in the extrusion die head can't finalize the design after a long time, after the loss of the molecular weight of buy, products under the action of drawing speed, can't make all products after heating. So, want to have good cooling conditions, must be kept stable and cooling speed of water level, poor cooling will also make the material in the second draft is affected, uneven in drafting, breaking even. So be good stable cooling conditions. The temperature of the cooling water tank due to the effect of heat, the surface to be smooth and stable cooling temperature, generally high temperature in the upper, lower temperature is low. So, after the products export mode, after sufficient at the bottom of the tank cooling to the drafting device.
