High temperature muffle furnace

 

High temperature muffle furnace application:

The resistance wire of the high temperature muffle furnace is the heating element. It adopts a double-layer shell structure and an intelligent temperature control system. The furnace is made of alumina polycrystalline fiber material.

The use of soft-start constant current control prolongs the life of the heating element, and the furnace has the advantages of high temperature control accuracy, balanced temperature field, simple operation, fast temperature rise and fall rate, and low energy consumption.

Installation and use of warm muffle furnace:

1. After opening the package, check whether the muffle furnace is intact and whether the accessories are complete- The general muffle furnace does not need special installation, but is only placed flat on the indoor flat ground or shelf. The controller shall avoid vibration and shall not be placed too close to the electric furnace to prevent the internal components from working normally due to overheating.

2. A thermocouple is inserted into the furnace for 20-50mm, and the gap between the hole and the thermocouple is filled with asbestos rope. Connect the thermocouple to the control * and use the compensation wire (or insulated steel core wire). Pay attention to the positive and negative poles and do not connect them reversely.

3. Another power switch shall be installed at the inlet of the power line to control the main power supply. In order to ensure safe operation, the electric furnace and controller must be reliably grounded.

4. Before use, adjust the thermometer indicator to the zero point. When using the compensation wire and cold end compensator, adjust the mechanical zero point to the reference temperature point of the cold end compensator. When not using the compensation wire, adjust the mechanical zero point to the zero scale position, but the indicated temperature is the temperature difference between the measuring point and the cold end of the thermocouple.

5. After checking the wiring and confirming that it is correct, cover the controller housing. Adjust the setting pointer of the temperature indicator to the required operating temperature, and then turn on the power supply. Turn on the power switch. At this time, the green light on the temperature indicator is on, the relay starts to work, the electric furnace is powered on, and the ammeter has current display. With the increase of the internal temperature of the electric furnace, the pointer of the temperature indicating instrument also rises gradually, which indicates that the system works normally. The temperature rise and constant temperature of the electric furnace are indicated by the traffic light of the temperature indicator respectively. The green light indicates temperature rise and the red light indicates constant temperature.

Structural design of all-fiber trolley resistance furnace

 This paper focuses on the structural design of a full-fiber trolley-type resistance furnace. It uses high-aluminum full-fiber modules, CrMn resistance strips and fiber seals to replace the traditional brick kiln-type resistance furnace structure. It saves 30% of the overall power and is energy-saving, environmentally friendly, and convenient. Applicable, safe and reliable features. Research on vacuum brazing technology of dissimilar metals This trolley furnace is mainly used for tempering and welding annealing of large automobile forgings such as 45, 50, 55, 12Mn2VB, 40Cr, 42CrMo, 32MnSiVS5 and other steels. It is also used for low-temperature processing of carbon structural steel, alloy steel, mold steel and other products. Effect of filler metal on vacuum brazing of cemented carbide and steel In the tempering treatment, the parts are heated to the process temperature in the furnace and then insulated, and then come out of the furnace to be air-cooled to complete the

Trolley oven use

 It is an energy-saving oven for industrial large-scale production. It is mainly used for drying transformer cores and coils, drying spray-painted electrical cabinets and parts, drying rare earths, and drying casting sand molds. Heat treatment process for wide and thick plates drying, motor drying and other uses. The trolley-type material inlet and outlet method is adopted, which is suitable for automatic inlet and outlet of large quantities of workpieces. Effect of filler metal on vacuum brazing of cemented carbide and steel In the production process of Qianshi transformers, processes such as core preheating, coil pre-drying, coil dipping and drying, and resin curing are very critical and directly affect the quality of the transformer. Therefore, they have a negative impact on the temperature uniformity of the curing furnace and the reliability of the control system. The requirements are very high. Research on vacuum annealing of titanium alloys The YBDX series of tran
