The electrothermal tube of large plate vulcanizing machine is mainly used for heating vulcanizing machine template. It is made of stainless steel pipe or common iron pipe. It is divided into single head and double headed pipes. According to the requirement of high surface temperature and hot insulation and leakage current under the working condition of the product, the high temperature magnesia powder and the oxidation resistant hot line are adopted in the internal design. If necessary, consult the Technology Department of the Golden Bay and choose high resistance. Temperature stainless steel pipes, fully considering the installation and use of the environment, and components sealing requirements for special treatment to meet customer demand for equipment heating element safety and life.

The main technical parameters of the electric heat pipe for flat vulcanizing machine are as follows: the working voltage of the single heat pipe for vulcanizing machine is 220 (V) or 380 (V). The power is made according to the temperature of the template. The diameter of the pipe is 14 mm, 16 mm, 18 mm, etc. The material can be SUS304 seamless pipe. The vulcanizing condition is that of the template is heated, the surface is polished and blackened, and the sealing is made of glass sealing and epoxy resin. Glue, electrical performance for long-term placement of insulation value greater than 50M, leakage current less than 0.5mA.

The main technical requirements of plate vulcanizer: the temperature is usually 180-200 degrees C, the surface load of conventional electric heat pipe is 3-7W/square centimeter, which ensures that the surface temperature of the plate vulcanizer template is uniform and the hole spacing of the template is arranged reasonably, so that the temperature difference on the surface of the hot plate can be controlled in a smaller range. Considering the convenience of installation and use of the electric heat pipe, the star joint method is generally adopted.

Flat-plate vulcanizer heat pipe is an electrothermal element specially designed for electric-heating flat-plate vulcanizer. Flat vulcanizing machine is the main vulcanizing equipment of rubber products, and the surface temperature difference of hot plate is the main performance index of Heng Flat vulcanizing machine. There are two main reasons for the large surface temperature difference of hot plate: 1. the temperature shadow of external environment; 2. the spacing arrangement design of electric heat pipe. Therefore, the key to solve the problem of surface temperature difference of hot plate of electric heat plate vulcanizing machine is to find out a smaller temperature difference between electric heat pipe and electric heat pipe. The relationship between distance and arrangement.
