Cupellation furnaces AGNI PK

According to the “Convention for the Control and Labeling of Precious Metals Products”, AGNI PK hot-swap furnaces fully comply with the necessary requirements. The Precious Metals Convention defines alloy purity standards for subsequent application of samples to products. The convention is also called “Assay” or “Vienna”.

The purpose of the cupellation furnace AGNI PK "font"

According to ISO11426: 1999, cupellation testing is carried out using this equipment. This method is standard, used in the UK state assay laboratory. According to the international convention, this method of quantitative analysis is a reference for the formulation of samples.

The cupellation furnace is used to determine the content of precious metal in a gold alloy (GOST 17234-71) or copper concentrate (GOST 15934.10-82). To determine the quantitative composition of gold or silver, oxidative melting on magnesite is used.

Equipment is necessary for cupellation of samples for assay. Tests are carried out according to TU 48-7-22-89 “Blister copper. Methods of analysis. " For cupellation of samples, industry methodology No. 117-2-15-90 is used, including methods for the analysis of gold-bearing ores and processed products.

Features of cupellation furnaces of AGNI PK “Kupel”

  • Temperature maximum - 1200/1400 ° С.
  • S-type thermocouple, 1-class
  • Execution of heaters - insulated wire heaters for highly aggressive environments.
  • Arrangement of heating elements: under and arch of the furnace.
  • Protection of heating elements from mechanical shocks, spills and aggressive fumes by silicon carbide plates.
  • Overtemperature protection with an independent temperature control system.
  • The preheated air enters the chamber through the hearth heaters, and eliminates accidental cooling of the chamber and the sample.
  • Smooth adjustment of the amount of air entering the chamber is achieved by a step flap.
  • The exhaust gas outlet is located at the back of the furnace on the wall. A quick-release condensate collector is installed in the ventilation duct.
  • Exhaust vent pipes are made of stainless steel.
  • Door opening, flat parallel, up. To facilitate opening, a counterweight and gas-filled shock absorbers are used.
  • When opening, the hot side of the door is facing away from the operator to protect against annealing.
  • The furnace door is equipped with a ceramic penetration with a plug to accommodate the control thermocouple.
  • The delayed start function to bring the furnace to the mode at the beginning of the work shift.
  • Placement of an electric unit is possible in a separate cabinet, or in a monoblock with an oven.
  • Ventilated inter-furnace space.
  • Confirmation of conformity of the measuring and control equipment of the furnace.

Additional equipment:

  • Tongs and fixtures for installing and removing fonts.
  • A set of personal protective equipment for the thermist consisting of: mittens, gloves, face mask, helmet, jacket. For short-term protection against exposure to an open flame, contact with heated surfaces more than 400 ° C.
  • A system for collecting, analyzing, storing and archiving information on firing to an external PC using the program AGNI DPC.Pro
