The benefits of electric furnace Under the condition of stable power supply, electric heating furnace has many advantages over fuel furnace, especially it does not need fuel storage, transportation, ash after combustion and huge flue gas discharge, purification and other devices, so it has a small footprint and simple installation. It has the advantages of convenient operation and management and no CO2, SO2 and other pollution; at the same time, it is easier to control and ensure the heating quality, and it can be heated as a whole, locally or on the surface, so as to have good quality and high thermal efficiency. Martensitic stainless steel vacuum sintering heat treatment Due to the above characteristics, electric heating furnaces are suitable for the manufacture of advanced materials and parts, and have good energy-saving effects, so they are widely used in electromechanical processing and assembly industries such as automobiles, motors, home appliances and electronics. In the future, with the stable development of the electric power industry and the increase of the processing industry and processing, resistance furnaces, induction furnaces and electron beam heating will continue to develop; in high energy consumption sectors such as iron and steel industry, metal products and kiln With the development of deep processing, high-quality products and ceramic materials, coupled with the control of energy saving and CO2, the proportion of electric heating will also expand; there are also microwave ovens, far-infrared heating in chemical, textile and food industries. The application of furnaces will also increase; at the same time, in the civilian area, microwave ovens and heat pumps will also be applied and expanded. Vacuum heat treatment furnace for copper alloys

The holding furnace is a type of material surface that is ignited and burned at high temperature. After leaving the igniter, it is suddenly exposed to the atmosphere, resulting in rapid cooling of the red-hot material surface. Therefore, in the mineral composition of the surface sinter, the glassiness increases significantly. Strength drop, an instrument of this drawback, is an important part of the low pressure casting furnace. Differences in vacuum heat treatment between aerospace blanks and parts It is composed of furnace body, molten pool, sealing cover and liquid riser, and is the basic part of low pressure casting machine. Step shaft vacuum quenching heat treatment There are many types of furnaces, such as coke ovens, gas furnaces, resistance furnaces, induction furnaces, etc. High speed steel vacuum heat treatment The advantages of this type of furnace are simple structure, convenient temperature control and good working conditions. The power of the holding furnace can only make up for the total heat dissipation loss.

In the traditional electric furnace temperature control system, most of the main circuits use AC contactors to control the power supply of the electric furnace, GCr15 Bearing Steel Effect Of Tempering Temperature On Microstructure And Properties and the furnace temperature is controlled by a combination of temperature instrument monitoring and manual adjustment. Although this control method has a simple structure, it has poor control accuracy, slow control speed, labor-intensive, high energy consumption, and high noise. Moreover, the contactor is frequently switched on and off during the temperature control process, and contact arc discharge often occurs. Short circuit, Shaft machining vacuum heat treatment damage the contactor, and adversely affect the safety of operators and equipment. Vacuum carburizing process of auto parts Therefore, the application of microcomputer technology to heat treatment process control is an inevitable trend to improve the quality of heat treatment products and reduce production costs.
