Casting of metal in medium frequency melting furnace
The principles of copper alloy melting
include: cathode copper (electrolytic copper), scrap generated during
processing, and outsourcing scrap copper. To achieve a reasonable alloy
composition ratio, the ratio of raw materials is directly related to the ingot
product. The key to quality and product cost.
In the copper alloy melting process,
according to the alloy composition ratio, suitable metal raw materials are
selected, melted and refined at high temperature, and alloy melts with
qualified composition are obtained. Melting and purification, through the use
of chemical reaction or physical absorption, sedimentation and other refining
measures to degas, to ensure the quality of the metal added to the metal.
Melting metal, the solid raw material is converted into liquid by high
temperature heating, so that there is enough fluidity to fill the cavity during
manufacturing.
In order to achieve the goal of reducing
production costs, the following principles are generally adopted: To produce
high-quality alloys, high-grade metal raw materials should be selected. When
producing ordinary products, try to choose low-cost raw materials before
ensuring the quality. For ordinary raw materials within the allowable range of
chemical composition, the ratio of precious metal elements should be as low as
possible.
Medium frequency melting furnace copper
alloy induction furnaces are generally divided into iron core induction
furnaces, ironless induction furnaces and vacuum induction furnaces.
The characteristics of iron-core induction
electric furnace melting are: fast melting speed, high thermal efficiency, and
less oxidation burn loss; due to the stirring effect of electromagnetic force,
it can ensure uniform composition and temperature; low ambient temperature, good
working conditions, simple operation and saving manpower; There must be a
certain amount of melt in the furnace, which is only suitable for continuous
production of large quantities and simple varieties.
