Electrode Drying Oven types are determined by the amount of electrode drying and storage, and the temperature control requirements. They can be divided into 30, 60, 100, 150, 200, 300, 500KG drying and storage capacities. If larger capacity is needed, non-standard electrode drying oven equipment can be designed separately. From the drying and storage method, it can be divided into single heating chamber type, which has a maximum drying temperature of 500°C, automatic temperature control, i.e., only drying function. If a storage chamber is added on the basis of a single heating chamber, the equipment utilization rate is improved. The drying chamber and storage chamber use independent circuits to measure and control temperature separately. The drying time in the drying chamber can be set, and an alarm will sound and the machine will stop when the time is up.
Purpose of the Electrode Drying Oven:
Welding electrodes absorb moisture during manufacturing, transportation, and storage. They must be dried before use to remove moisture from the coating; otherwise, the hydrogen decomposed from the moisture in the coating during welding will remain in the metal around the weld, causing cold cracks and welding quality accidents. In addition, the electrode drying oven can also be used as a holding oven after drying.
Product Performance:
Program automatic control, easy to operate; digital display of temperature and time, clear at a glance; stainless steel drawers, corrosion-resistant, extending service life; long heat preservation time, can preheat for about 20h, convenient for continuous work; independent rear cover installation, good heat preservation effect, solving maintenance difficulties; far-infrared heating, energy-saving; alarm function after drying and holding. Widely used in key national construction projects such as machinery, electric power, metallurgy, chemical industry, petroleum, and urban construction, it is an essential drying equipment for welding engineering.
Operating Procedures for Electrode Drying Oven:
1. Before connecting the power supply, set the temperature setting dial to the required heating temperature, and set the time relay dial to the required timing time;
2. After startup, check whether the display of each instrument and indicator light is normal;
3. Operators should understand the structure and usage of the drying oven and auxiliary equipment, as well as the layout of electrical circuits;
4. When loading and unloading electrodes, cut off the working power supply first to ensure operator safety;
5. When loading and unloading electrodes, handle with care to avoid damaging the furnace lining, control box, and instruments due to impact and throwing;
6. Do not put flammable, explosive, or volatile items inside the oven;
7. Operators should regularly remove coating residues from the furnace chamber to keep it clean;
8. In case of malfunction, handle it promptly or report to the relevant department for processing.
