Small amounts of metal, such as 3 or 5 kg, are melted using A03 vacuum casting machines.

A graphical user interface with LCD display that can store up to 100 channels of timing and working temperatures simplifies all operations.

Our furnaces feature two heating chambers that operate with separate heating zones and temperature settings.

A tubular frame and panels with louvres for air exchange are used to construct furnaces. General maintenance interventions are easier with a tubular system.

Heating muffles are made of resistance and unique, highly thermally efficient refractory insulating panels. Strong temperature changes can be handled by a special heating chamber made of stainless steel.

Due to belt movement, internal sliding blocks prevent chamber wear and tear. Water is used to cool the cooling chamber. The chambers are held together by a flange, and a nozzle on it allows gas to enter. In order to improve de-oxidation, two burners are placed in front of the tunnel's two ends.

Our annealing furnaces are constructed of panels with Louvres for air exchange and a tubular frame. General maintenance interventions are easier with a tubular system.

Heating muffles are made of resistance and unique, highly thermally efficient refractory insulating panels. Strong temperature changes can be resisted by special stainless steel heating chambers.

Protection gas enters the chamber through nozzles. The de-oxidation process is improved by a burner placed in front of the chamber to prevent oxygen entry. Inside is a shovel made of stainless steel.

When annealing metal, you simply push the pale to the bottom of the cooling chamber and drop it into the water tub for instant cooling (or leave it lying in the cooling chamber to cool, taking some time). The tub's treated material is removed either manually or (optionally) with a pneumatic piston.

MELTING Furnace iD series tilting The components of the static tilting furnaces are a swivel head on which the heating inductor is mounted and two flexible copper water-cooled cables connecting it to the MF induction.

The solid aluminum frame holding the medium frequency induction circuit with fast melting speed is surrounded by powder-coated panels.

The rotation is on two points by a motor acting on a tree where they placed two pulleys, and the swivel head is constructed of panels made of aluminum plates and Sindanio asbestos-free panels mounted on a stable base.

All of this is managed by a rollover and emergency control panel.

The process takes place inside a work tank which is placed strictly under the hood and under suction, housed also on the upper floor of the building structure. This will allow, with some modifications, to discharge the liquid of the saturated solutions, inside the crystallization system, which will be placed under them and therefore on the lower level. This crystallizer is wheeled and equipped with a Buckner filter for collecting gold salt.

The work tank will also be equipped with a movable lid, with tilting opening and connected separately to a reflux head in glass, for the condensation of the produced vapors, which will consequently be directed inside the tank to which they are bound. This system avoids decreases in volume in the tank and therefore negative variations in the concentration of the salt in solution, thus automatically guaranteeing the right final title.

Downstream of the process, a liquid treatment system is envisaged for immediate recovery of the residual gold.

"THE BENEFITS OF RECYCLING TECHNOLOGICAL WASTE According to research and facts , it is 13 times more costly to extract minerals from natural deposits than it is to recover them from technological waste for the manufacture of new devices. Obtaining minerals like platinum, copper and palladium does not just involve digging them up and processing them, it also requires the use of huge quantities of water and energy. This is where the concept of the circular economy comes in, based on the use of materials from recycled items and less dependence on the virgin resources extraction."

WHAT IS AN ELECTRIC FURNACE ? 

An electric furnace is a device whcih generates heat due to the resistance offered to the passage of current that is passed through it.

The furnace provided by us is of indirect heating type, which implies there is no contact between the heating element ( we use high quality & long lasting kanthal heating element ) and the crucible.

HOW DOES IT WORK ?

When you put the power on of the furnace , the current passes through the kanthal coil and heat is generated due to ohmic resistance and the coil becomes red hot ; This heat is transferred to the crucible by radiation which melts the material that is inside the crucible.
