Smelting bronze

In the prepared - hardened and thoroughly dried crucibles made of refractory chamotte or carborundum, with the addition of graphite is loaded; the melting phase begins with copper, which is added to the crucible in small portions. Technologically advantageous to use copper with a high content of phosphorus, as compounds formed during the melting process more easily bind and are removed from the crucible; Addition of tin andHeating of the crucible contents to temperatures of 1150...1200°С, during which the salt fluxes are added, ensuring the required degree of chemical purity of the melt;

Cleaning

Purification from dissolved gases, the main of which is hydrogen. This is done by purging with inert gases; Pouring the prepared melt into the molds. Pouring the prepared melt into the molds using inert gas purging; Casting the melt into the molds using carbon-containing compositions: this reduces the risk of the product sticking to the mold during solidification. Supplier Evek GmbH offers to buy bronze of domestic and foreign production at an affordable price in a wide range. We provide delivery of products to any point of the continent. The price is optimal.

Equipment for the production of bronze alloys

• Arc or induction electric furnaces. Electric heating of the melt provides its increased homogeneity, and reduces the loss of the final product up to 0,6...1,0%;
• Indirect heating furnaces in which the required temperatures are achieved by initiating a powerful electrical discharge between the carbon/graphite electrodes immersed in the feedstock;
• Traditional casting furnaces with an open crucible. Their share in bronze production is steadily decreasing, nowadays such equipment is used mainly at small repair plants.

The technological parameters of furnaces operation are determined by the complexity of bronze castings configuration, production volume, bronze alloy composition. Particularly, if the oxide film doesn't form during the melting process, the furnaces don't have complicated and expensive slagging system.
