Foundry Ladle Preheater
For the safe and effective transportation of molten metal to a ladle, pre-heating is required. Modern ladle metallurgy requires higher temperatures in order to pour consistently.
HEZHI offers a complete Ladle Pre-Heating System that works in conjunction with your molten metal system. The system operates on natural gas or electric.
A casting furnace, more commonly referred to as a furnace, is a device used to heat and melt metal ore to remove gangue, primarily in iron and steel production. The heat energy to fuel a furnace may be supplied directly by fuel combustion, by electricity such as the electric arc furnace, or through induction heating in induction furnaces. There are several different types of furnaces used in metallurgy to work with specific metal and ores.
Induction heating is the process of heating electrically conductive materials like metals by electromagnetic induction, through heat transfer passing through an induction coil that creates an electromagnetic field within the coil to melt down steel, copper, brass, graphite, gold, silver, aluminum, and carbide. An induction heater consists of an electromagnet and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet. The rapidly alternating magnetic field penetrates the object, generating electric currents inside the conductor, called eddy currents. The eddy currents flow through the resistance of the material, and heat it by Joule heating. In ferromagnetic and ferrimagnetic materials, such as iron, heat also is generated by magnetic hysteresis losses. The frequency of the electric current used for induction heating depends on the object size, material type, coupling (between the work coil and the object to be heated) and the penetration depth.
