We offer most advanced Zinc melting furnace of capacity ranging from 1 ton to 50 ton. Different variations are possible to suit specific customer requirement.

Our furnaces are available in different variant like box type furnace, hydraulic tilting furnace and small crucible type furnace for the processing of zinc oxide.

Arihant Engineers Ingot Casting machine has been developed to give trouble free production of all type of non ferrous metal and its alloy. Metal is poured from the furnace in to the casting wheel/Tundish and the system accurately controls the volume of metal in to each mould. The filled moulds travel up the incline , where they are water cooled. As the molds pass around the head sprocket , they invert , allowing the ingots to fall by gravity- assisted by two knock out hammer.

Mould type - 25 kg capacity
Mold Dimensions – 600 mm long x 100 mm width x 40Mm height
Number of molds – 60
Mould material – SG cast iron
Mould cooling – Water spray , 9 spray heads, Total water consumption At 2 bar pressure 100 lts per hour
Knock out system – Automatic dual Knock out system
Pouring system – Casting wheel/ Cam operated tundish , Drive off main chain
Drive Motor – 2 HP AC variable frequency drive
Gear box – 750:1 double reduction worm gear
Conveyor chain – 150 mm pitch bolted assembly
Machine inclination – 13 degree
Machine construction – Robust frame fully welded

The equipment shall consist of an MS ring mold of 1200 mm diameter support-ed on a heavy duty fabricated steel base frame. The drive to the ring mold is by variable frequency drive system and motor through double stage reduction gear box . The equipment is essentially a four wheel construction to cover the outer face of the ring mold by an endless steel belt. The caster is provided with inner and outer SS spray nozzle. Each nozzle can be controlled individually for fine setting of solidification pattern of as cast strip. The belt guide rollers are pneumatically operated with pressure control valve to regulate the working pressure between ring mold and belt guide rolls. The width of as cast strip shall be 300 mm with a minimum thickness of 20 mm. The production capacity of the caster shall be 2 tons per hour.
 

We provide complete plant on turnkey basis for the manufacturing of Zinc wire by continuous casting , rolling and wire drawing process .

Process description

Zinc ingots are loaded in to the hydraulic tilting type zinc melting furnace. Mol-ten zinc from the melting furnace is fed to the continuous caster . The cast bar from the caster is passes through tandem rolling mill for size reduction. A round wire of size 5.5 mm is produced by continuous casting and rolling pro-cess. Further size reduction is carried by specially designed wire drawing ma-chine. Wire produced is packed in cardboard drum by drum packer machine.

Technical details

Universal Tilting Rotary Furnace is a new generation of Rota table and tilt able melting furnace for secondary non ferrous metal extraction. This furnace is lat-est of its kind in the world.

A significant advantage claimed for the UTRF is that it can be both rotated and tilted. First of all, the scrap is loaded in to the furnace with the smelting salt and the furnace is locked shut. By firing the burner that is mounted on door the material is heated with the help of air and oil/gas until it reaches melting point. Heating up is considerably faster resulting in saving of energy as well as melt loss. During the whole melting process, the UTRF rotates. This improves the heat transfer rate from the burner to the material, and additionally, the ro-tating movement promotes the separation of liquid metal from the oxide and other impurities. When all the scrap is melted, the burner can be switched off.

After opening the furnace door, the liquid metal can be poured in to the holding furnace or to the other station by tilting the furnace. Through tilting the fur-nace even further the salt cake can be taken out. Using the UTRF enables a very high yield of material to be delivered with very low energy consumption.

If compared with traditional reverbaratory furnace the yield is 2 to 5 % higher and the energy saving is to the tune of 25 to 40 %. Another significant ad-vantage by this furnace is that metal can be recovered efficiently from the dross. This furnace is highly useful in making master alloy as during the whole melting process the furnace rotates resulting in homogenous mixing of other elements in metal.
