Umaxe Regenerator is added to the Umaxe 660720830970 baths to avoid Decarburization by maintaining regular additions. It should be added when the bath is at the normal operating temperatures. It forms a layer on the bottom of the pot and this layer tends to become hotter than the salt. Care should therefore be taken while inserting the thermocouple end from dipping in to this layer.

Umaxe 830 is used in the above working range for Hardening of various Chromium steels; Rust resisting tool steels and various Hot Working Die steels. Umaxe Regenerator is used at the rate of 125 gms per 100 kgs of UMAXE830 per 8hrs a day. For every 8 hrs, the bath should be sledged accordingly.

Umaxe 720 is used with Umaxe Regenerator as a Neutral salt which gives freedom from Decarburization. It neither has a tendency to carburize the steel. It has an excellent tendency to readily soluble in water. Umaxe 720 is used in the above working range for Hardening of various Carbon steels, Alloy steels, Tool steels. Umaxe Regenerator is used at the rate of 325 Gms per 100 kgs of Umaxe 720 per 8 hrs. a day.

Umaxe 660 is used in the above working range for Hardening of various Carbon steels, Alloy steels, Tool steels and for pre heating the High speed steels and Hot working Die steels before treating them in Umaxe 970.The bath gives Freedom from Decarburization and Umaxe 660 is less soluble in Water. Umaxe Regenerator is used at the rate of 225 Gms per 100 kgs of Umaxe 660.

Umaxe 540 is used at a temperature of 500600c for quenching the components From Umaxe 970 salt bath. It gives minimum distortion and less cracking than when oil quenched. The components are soaked in the bath reasonably long enough and taken for air-cooling. These components are subsequently tempered in Umaxe 495. High-speed steels are Tempered preferably twice for air-cool in between.The tempering temperature will be in between 520570c.

Umaxe 495 has a lower melting point and can there fore be used at lower temperature of both quenching and tempering of High-speed steels. Umaxe 495 alone is used for making up the initial melt and for maintaining the correct level, The bottom of the pot should be dredged periodically to remove the sludge.

Umaxe 220 is widely used for the tempering and gives much uniform results at a low cost. It is widely used for quenching in Austempering and Martempering. The bottom of the bath should be dredged daily to remove sludge.

Umaxe 150 is widely used for the tempering and gives much uniform results at a low cost. It is widely used for quenching in Austempering and Martempering. The bottom of the bath should be dredged daily to remove sludge.

Applications of Retort Type Furnace :Optional equipment can be added permitting heat - and surface - treatment process employing a variety of atmosphere gases and temperatures. the retort design permits free alternation between process without interaction, that is to say, permits carburising-quenching, corbonitriding, gas soft nitriding and other processesFeatures : Conventional brick type furnace has the remarkable features as instructed but the retort type furnace has the additional splendid features as follows since the interior of the furnace is sealed completely by the heat resistant metal retort. Seasoning and drying processes are not required for Retort type furnaces. Retort type furnaces consumes less than one-third the atmosphere gas of conventional designs. Retort type furnaces permits full weekend shutdown. Retort type furnaces allows atmosphere gas to be changed quickly and easily without burnout process.

Decarb Annealing Cum Blueing Furnace

With batch type design, typically an electrically-driven, insulated car is used to move a load into and out of the furnace. Often, a double-ended furnace (door at each end) is used with two cars so that turnaround time on the Aluminum Homogenizing furnace is reduced, thus maximizing production.The alternative to the car bottom design for the batch type units, is the tray design. With this design, the load tray rests on a series of support posts inside the furnace. A charge machinetransfer car is used for chargingdischarging of the tray and transferring the tray from the Aluminum Homogenizing furnace to a cooling station or to a loadunload station.A third type of batch unit is the traveling furnace. This type of Aluminum Homogenizing furnace utilizes a pair of fixed load bases to support the load. When the cycle is completed on base no. 1, the furnace moves into position over the second load base and immediately begins heating a new load. The previous load is allowed to cool and then unloaded and replaced with a new load. This can all be accomplished before the next homogenizing cycle is completed. A traveling furnace provides savings in floor space since the two load bases require significantly less floor space than a double ended stationery Aluminum Homogenizing furnace with two load cars.
