What are the principles for controlling the temperature of the furnace charge in a copper melting fu

Wuxi Huadong Industrial Electric Furnace Co., Ltd. will discuss with you in detail the principles for controlling the temperature of the furnace charge in the copper melting furnace. What are the following?

Copper melting furnace, which has uniform heating temperature, less burning loss, uniform metal composition, good casting quality, fast melting temperature rise, easy control of furnace temperature, and high production efficiency; The power conditioning of a copper melting furnace is sensitive, convenient, and can be continuously and smoothly adjusted; Uniform temperature, easy to control, less oxidation and burning loss, and uniform metal composition; The furnace shell adopts cast aluminum alloy or steel shell structure, with a small floor area; The furnace body is turned upside down for convenience.

1、 What are the principles for controlling the temperature of the furnace charge in a copper melting furnace?

China is a large country in aluminum production, but compared to other developed regions, the overall industry structure is unreasonable, and the scale of the renewable aluminum industry lags behind. Developing the renewable aluminum industry can solve the crisis in China's aluminum industry, meet the development trend of the world's aluminum industry today, and meet the needs of policies related to sustainable development and the scientific concept of development in China.

The intermediate frequency power supply for the copper melting furnace uses an integrated IGBT power module in its inverter part, which integrates functions such as driving, protection, and locking. It uses a customized low inductance composite busbar with high insulation level and low leakage inductance. The parallel IGBT has good current sharing effect, high reliability of the power module, and a 10% reduction in energy consumption.

The principle for confirming the outlet temperature of a gas fired copper melting furnace is to ensure that the metal has a certain fluidity; Ensure the normal operation of casting and prevent defects such as cold shuts and slag inclusions; Ensure gas precipitation during melt solidification; According to the casting characteristics of different alloys, low temperature tapping should be used as much as possible while ensuring the normal casting operation.

2、 There are two types of furnace charge temperature control for copper melting furnace: indirect and direct.

Indirect temperature control is usually achieved by changing the voltage, current, and power of the inductor.

Direct temperature control refers to the automatic control system using the furnace charge temperature as the direct control object, adding units such as temperature regulators, temperature transmitters, and temperature setters.

Thermal insulation function of gas melting copper Stainless steel crucible has a multi component structure with a strong protective sleeve outside, which has a good thermal insulation effect, and only requires 2 degrees of electrical cloth per hour for thermal insulation;

Copper melting furnace saves costs - no need to increase fuel, reduce fuel storage space, no need to lay smoke exhaust pipes, greatly saving labor costs and plant costs; Long lifespan - Under normal usage, the lifespan is greater than 5 years.
