We at Pyrotech Engineers, are proud to state that we are one of the few names to offer premium Crucible Melting Furnaces that are easy to install and require less maintenance. Manufactured as:

• Melting furnaces
• Melting cum holding furnaces
• Holding furnaces (only for Aluminum) are mainly used in gravity die casting
• Sand casting
• Pressure die casting units

Featured with high thermal conductivity, thermal shock resistance, lower mental loss, they also have high oxidation and corrosion resistance.

We also offer premium Bulk Melting/Tilting Furnaces that are mainly used for random melting of runner, raiser and ingot. These furnaces are also used for the preparation of molten metal. In addition to this it is to be noted that after melting the molten aluminum, it is treated for de slaging and de gassing. These furnaces are indirectly fired by gas or liquid fuel and metal is tapped by tilting the furnace.

The tilting is done by manually or with the help of hydraulic cylinders.

1. Manual tilting furnace: Here the tilting furnace is held on two shafts mounted on bearing blocks and this shaft is actuated manually by work and worm gear with steering type handler.
2. Hydraulic tilting mechanism: Here the furnace is held as explained in manual tilting mechanism and a hydraulic cylinder is used for tilting the furnace along with the hydraulic power pack.

Designed for LPG firing, we offer premium Bogie Hearth furnaces. Here by implementing gas firing we insulate the furnace using ceramic fiber module lining. These furnaces have walls, roof and also have movable bogie hearth. Here Bogie can be placed on wheels to move manually or mechanically using winch mechanism.

In this system the door sealing is provided by butting door lining and collar lining. In addition to this hearth brick to brick sealing is provided by stepped lining and bogie have stand sealing arrangements all over bogie sides except front or side. These Bogie Hearth furnaces (gas fired type) are also provided with single burner up to 2 tonnes batch capacity.

We are also proud to introduce ourselves as one of the leading names to offer Bell Furnaces as per clients' requirements. This product is widely used for annealing, stress relieving of casting etc. Here the heat treatment operation is controlled by cooling cycle. This unit is provided with 3 starts and the heat input during heating cycle can be utilized in the next set up by sucking of heat to preheat. In addition to this the raw materials as well as recuperators are used to pre heat the combustion air. The third bed is used for loading and unloading raw material.

Advantages:

1. Maximum heat utilized for heat treatment.
2. Loading and unloading can be done, for which the production will not stop.
3. More weight components can be easily handled.

Designed in accordance to international quality standards, we also offer premium auto control systems. In our designed auto control system, the furnace molten metal temperature is precisely controlled by using a control panel and the burner is operated with pilot burner system with sequence controlling activity. Intially the blower start and the ignition in the pilot burner start working and then the fuel valve is opened. Once the fuel valve is opened the combustion continuous. It is to be noted that here High/Low firing is implemented. It consist of crucible cover plate, that is fixed so that the level of molten metal in the crucible always remain low. A mechanical fiber sealing is also provided on crucible top from combustion gases escaping in between crucible top collar insulation.

This world-class units are widely used for manufacturing for steel manufacturing units. The core drying and mould drying ovens are mainly used for continuous production. It also consists of core shooters, that are placed mainly on the two sides of in-let of these ovens so that the core prepared can be placed on trays.

Advantages:

1. Labour is reduced as the material is loaded directly on conveyor.
2. Continues production is possible.
3. Heat energy is saved.

Justifying our position as one of the leading manufacturers off premium products, we also manufacture On-line pre-heating systems. These systems are mainly used in fasteners unit. Here the fasteners can be loaded as bulk in conveyor furnace for pre heating, heating and soaking and in final quenched in oil quenching tank. Moreover the quenched fasteners are taken out using elevators loaded in a screw type hopper system from which the fasteners are further loaded continuously in tempering line conveyor.

Designed in accordance to international standards, we offer stationary pre-heating systems that are mainly used for following requirement:

1. Curing the moisture level of lining and removing water particles to to achieve best castings production.
2. Heating for elevated temperature, so that the metal tapped should not reduce the temperature of molten metal.
3. Reducing the melting temperature of steel.

Note: On request the system can be manufactured for Scrap Pre-heating as well as Ladle Pre-heating system.

We at Pyrotech Engineers, are also one of the few names to offer premium Recuperator system at competitive prices. This system is a heat recovery system which can be installed on exhaust path. Designed in accordance to air/fuel ratio, it consists of a recuperator, that is selected according to air/fuel ratio the shell and tube type.

It is to be noted that the recuperator can pre-heat the combustion air to the tune of 250 C to 300 C and preheated combustion gases are used along with the fuel as combustion fuel mixer. Its chimney is designed up to 1 meter level from the furnace top and atmosphere temperature can be be felt by the operator or shop level from the furnace top. In addition to this the carbon content is very much less and is within the population control board norms.

We are one of the few leading names to offer raw-material pre-heating system at industrial competitive prices. Here the exhaust gases are taken in a Duct, Bend and focused towards raw material placed in a tray assembled on the furnace top cover, so that the raw material can be pre-heated to the tune if 200 C to 250 C.

It is to be noted that in this system, the raw material is preheated more than 100 C, and the moisture observed by the raw material is removed so that during melting and production process the gas inclusion can reduced. Moreover, since the raw material is heated up to 200 C to 250 C the heat value to melt the aluminum/copper/brass is drastically reduced and fuel quantity is reduced there by the working cost is reduced.
