Medium frequency induction heating furnace: Use of SCR
2022.11.28
Industrial furnaces are used to melt metals and there are many types on the market. We use the medium frequency furnace is the most, the induction heating principle.
The metal heating of induction heating equipment is also called medium frequency induction forging furnace, medium frequency induction diathermy furnace, medium frequency induction forging pre-heating furnace, medium frequency induction heating furnace, medium frequency induction electric furnace.
SCR medium frequency induction heating furnace refers to the medium frequency induction heating furnace power supply using SCR as the main frequency conversion component.
The commonly used SCR full-bridge parallel inverter frequency conversion power supply or SCR half-bridge series inverter frequency conversion power supply.
The induction heating furnace using SCR as the intermediate frequency power supply is often called the SCR intermediate frequency induction heating furnace.
Principle of SCR medium frequency induction heating furnace:
The middle frequency power supply of the SCR medium frequency induction heating furnace is the SCR frequency conversion device, which can convert the three-phase 50Hz AC to the commonly used heating frequency of the medium frequency induction heating furnace.
In SCR parallel inverter of SCR medium frequency induction heating furnace, the parallel compensating capacitor and induction coil of electric furnace form their own oscillation loop to reduce the load of electric furnace.
Use of SCR medium frequency induction heating furnace: used for integral or local induction heating of steel rod, steel pipe, copper rod, aluminum rod, stainless steel and other metal workpiece.
SCR medium frequency induction heating furnace heating material: carbon steel, alloy steel, Q235q, Q345q, Q245R, A32, D32, A36, D36 and other materials of metal workpiece
Heating temperature: medium carbon steel heating temperature: 1250℃ Temperature difference requirements: radial temperature difference ≤60℃, head and tail temperature difference ≤80℃
The characteristics of SCR medium frequency induction heating furnace:
Uniform heating temperature, high temperature control precision, small temperature difference, no pollution.
Module devices are used to replace single power devices in power rectification and inverter circuit of SCR medium frequency induction heating furnace. In order to achieve greater power, power devices are used in series, parallel or series parallel
High startup success rate and strong reliability. Variable frequency/variable load adaptive, maximum specifications and varieties of steel induction heating capability. Users can choose artificial furnace or automatic furnace can be widely used, so that the induction heating furnace utilization rate reaches the highest.
SCR medium frequency induction heating furnace control circuit and protection circuit a large number of digital integrated circuit, ASIC, simplify the circuit design, improve the reliability of the equipment.
