Baoding precision instruments to you on the next open mill to solve the control problem of temperatu

1, open smelting machine around the electric heating: a single heating wire power can be 2.1KW. The effect of temperature difference between the two ends of more than and 10 degrees, more than a few degrees. The utility model is mainly that the heating wire can not be closely matched with or can not contact with the inner wall at all. Using this method, the main performance for the heating wire after a period of time to dry deformation, difficult to replace, temperature inequality. However, due to the power of the heating wire is relatively large, relatively strong structure, not easy to burn out.
2, open the single head electric heating tube: single heating wire single stick in the diameter of 19.8 power for 1.7KW. In this way, the temperature is uniform, and the precision can be 2 + C. The disadvantage is that the heating speed is slow, the power is small, such as the increase of power, can cause the heating tube is easy to burn, increase the replacement time and frequency.
3, open the use of special heating machine mold, with three heating pipes, power can be done 3.6KW, such as 2.7KW, so that the heating wire pressure greatly reduced. Due to the special mold through the deep hole, so that the hole and the heat tight fit. Can guarantee the longer life of the heating tube, and the roller surface temperature accuracy of 2 degrees or higher
4, open the oil heating cycle heating mode: the use of high temperature oil heating, high temperature oil pump through the circulation of high temperature oil, so that the high temperature oil in the drilling of the cylinder inside the cylinder to achieve the temperature of both ends of the mixer cylinder. The utility model can greatly reduce the error of the two ends of the temperature and improve the precision of the product, thereby winning the market competition ability.
