These are laboratory tube furnaces upto temperature of 1500'C. For High Temperature (upto 2200'C) and High Vacuum (10-3 mm of Hg) we import such furnaces from our principals in USA.
These furnaces are available for following temperature ranges;
These are used for different types of Heat Treatment processes like Annealing, Normalising or Hardening.
PID programmable Temperature Controllers, Thyristor Power Regulators are Standard Equipment for such furnaces.
Touch Screen (HMI) control Panels and Paperless Temperature Recorders are optional features available at extra cost.
These type of furnaces are in use for batch type operations where big size charging materials are to be loaded through overhead cranes or forklifts, necessitating the hearth to come out for loading and unloading operations.
Normalising is a type of heat treatment which every factory needs. Normalizing is a technique used to provide uniformity in grain size and composition throughout an alloy. The term is often used for ferrous alloys that have been heated above the upper critical temperature and then cooled in open air. Normalizing not only produces pearlite, but also bainite and sometimes martensite, which gives harder and stronger steel, but with less ductility for the same composition than full annealing.
These furnaces with Max. Temp. Of 1000’C hold Aluminium in Iron Pots for following processes.
Once a day, workers siphon aluminium from the potlines. Much of the metal is set aside to become fabricating ingots. To make a fabricating ingot, molten aluminium proceeds to large furnaces where it can be mixed with other metals to form alloys. From there, the metal undergoes a cleaning process known as fluxing. Fluxing uses gases such as nitrogen or argon to separate impurities and bring them to the surface so they can be skimmed away. The purified aluminium is then poured into molds and cooled rapidly by spraying cold water over the metal.
Some of the aluminium siphoned from the potlines isn't alloyed or cleaned. Instead, it's poured directly into molds, where it cools slowly and hardens to form foundry (or remelt) ingots. Primary aluminium plants sell remelt ingots to foundries. Foundries return the aluminium to its liquid state and proceed with the alloying and fluxing themselves. They then turn the aluminium into various parts -- for appliances, automobiles and other applications -- by using the following fabricating techniques.
These furnaces are used for heat treatment of small components kept in a wire basket where temperature uniformity is obtained by the flow of hot air from a fan thus ensuring same temperature even to the farthest component from the heating elements.
These are used mainly for Sintering and are imported from our Principals in the USA. The unique design makes water cooling redundant and very small power input ( about 3kW) or so can raise temperature within a 5cm dia pot to a temperature as high as 2200'C.
These are conveyor type furnaces where process goes on continuously and materials enters from one end and comes out after the process from the other end.
These ovens are very useful for paint drying , mould drying and electronic components manufacturing industry, apart from host of other applications in laboratories.
