1000kg Crucible Dosing Holding Furnace Aluminum

1000kg Crucible Dosing Holding Furnace Aluminum 

1. EQUIPMENT INTRODUCTION

The dosing holding furnace is mainly used for maintaining temperature of molten aluminum and fixed supply of aluminum during aluminum die casting. For the furnace, aluminum is supplied by gas pressurization and an expert-based dosing calculation procedure is adopted, realizing the quantification of aluminum supply and high-efficiency production. The furnace is a new-type holding furnace manufactured by the company using our self-developed “dosing control technology” based on years of experience in producing low pressure holding furnaces and automatic liquid surface compression systems.

2. Equipment Features

 • The molten aluminum outflows from the lower part of the molten pool, not mixed with oxidation slags on its surface.

• High dosing accuracy, the dosing accuracy<± 1.5% (by weight).

• The furnace is closed heating, minimizing the oxidation loss of molten aluminum to≤0.1%.

• The molten aluminum is of high quality owing to less hydrogen absorbed.

• The high consistency of casting weight, casting flow rate, casting speed, casting temperature and casting time and other parameters prevents various casting factors from affecting casting quality.

• It can be equipped with an in-line air brick degassing and refining device to continuously provide high-quality molten aluminum.
