About Us

Started in 1993, STOKER CONCAST has come a long way since then. The company that had originated as a manufacturer of simple horizontal continuous casting machines has now metamorphosed into a company whose strength lies in its innovative technological approach and constant upgradation of its designs and products with users across the globe.

STOKER CONCAST technology is reliable, economic & simple to adopt for production of rods & tubes of copper & copper based alloys. Stoker Concast has become an established name in the field of continuous casting. The company is committed to technical innovation and continual research to provide its users with the benefits of the latest engineering developments based human machine interface

 

Horizontal Continuous Casting Machine


Horizontal casting machines. These are widely used for manufacture of copper based alloys, specially higher diameter rods, strips & tubes. The main advantage of horizontal process is high value of production for higher sizes of rods, strips & tubes homogeneity of alloying elements and large dendritic grain structure. he concept of continuous casting is a melting cum holding furnace with a graphite crucible heated with highly efficient graphite resistant heating elements furnace with a cooler, together with graphite die and cooler assembly and run out track with withdrawal machine and cut-off device. Molten metal flows from the crucible into the graphite casting die which is cooled with the help of a highly efficient cooling jacket. Water-cooled graphite dies are attached horizontally to the holding crucible. During the continuous casting operation metal flows into the graphite casting die where it solidifies. The solidified strands are intermittently withdrawn in a "pull-pause" sequence by means of withdrawal equipment. After leaving the graphite die, which is housed within the primary cooler, the cast strands pass through a secondary cooler in the form of a water 'sparge' which removes the surplus heat contained in the solidified billet. Water 'sparge cooling' beyond the exit of the die is much more thermal efficient than using a graphite water-cooled sleeve cooler. The machine is well insulated with a low thermal mass high temperature zirconia ceramic modules for high thermal efficiency. The majority of continuous casting installations in use today operate in the horizontal mode. The reason for this is mainly logistic, based on ease of product handling and to some extent safety in operation. There are, of course inherent problems applying horizontal as opposed to vertical casting mainly to gravity-induced directional cooling. However, in most cases These difficulties can be accommodated. The horizontal continuous casting machines are graphite resistant heated furnace. A graphite crucible and die assemble is heated with a set of graphite heaters. The heaters have specifically been designed for having a balanced three phase system which makes it easier to operated on A generator. The graphite heaters are placed in the areas where the heating is actually required to have the maximum utilization of the heat & be user friendly.

Vertical Continuous Casting Machine

Aleading manufacturer of Vertical Continuous Casting Machine For Copper in the shape of rods, strips & tubes directly from scrap or virgin copper (Cathode) & copper based alloys including precious alloys. These machines are specially suitable for smaller diameter rods for wire rod industry. The feed metal in the form of swarf, turning, borings, chips etc of the alloy are fed from the top into a graphite crucible which has two portions & is heated by graphite heating elements. It is a resistance heated furnace. At the top of the crucible a super - cooler assembly, along with graphite die, is fixed vertically keeping the die immersed in molten metal. The super cooler is cooled by re-circulation of water. The molten metal enters the die & gets solidified in the shape of die bore. The solidified metal is continuously withdrawn at very fast speed with the help of withdrawal unit driven by SERVO motor, coupled with gear box.there by giving a continuous length of the casting in the shape of rod strip or tube.Principle of Vertical Continuous Casting: Concept consists of graphite heating element, heated furnace with graphite crucible furnace and holding furnace, together with graphite die and super cooler assembly with withdrawal mechanism driven by PLC based servo motor crucible is made of two parts used for  Melting of scrap / Virgin metal, Casting / Holding Unit.Molten metal from the melting side enters in the casting and holding unit. which, acts as a reservoir of molten metal maintaining the required casting temperature.
The furnaces for melting and for casting are lined with refractory high-alumina fire bricks and with low mass insulation for minimum heat loss. The melting takes place under a reducing atmosphere with a floating charcoal or graphite flake cover, ensuring minimum reaction of oxygen from air. Under the prevailing reducing conditions the service life of the refractory is generally extremely good.
Water-cooled super coolers with graphite dies are mounted on top of the holding crucible.During the continuous casting operation metal flows into the graphite casting die where it solidifies. The solidified rod is intermittently withdrawn in a 'pull-pause' sequence by means of withdrawal equipment, driven by PLC based servo motors with touch screen molter. After leaving the graphite die, which is housed within the primary cooler, the cast strands pass through a copper tube called super cooler through which cooling water is passed at a specific flow & pressure maintained automatically in which removes the surplus heat contained in the solidified rod.
Vertical Continuous casting machines are best suited for Wire rod industry for casting copper rod or copper alloy rod.

Horizontal Cum Vertical Caster Machines

Horizontal Cum Vertical Caster Machines
True to its reputation of being a company that believes in innovation and innovative techniques, Stoker Concast (P) Ltd has once again taken the lead. In the first of its kind, we have developed and successfully launched a versatile machine that can cast horizontally and vertically simultaneously.  While the vertical caster is in use for casting rods for the wire industry, or for casting thin walled tubes for refrigeration and in the automobile bush industries, the horizontal mode can be used for casting larger sections of billet , thick walled tubes for extrusion press or casting strips for bus bar industries. This gives the machine the following distinctive advantages: The scope of casting is significantly increased through simultaneous use of horizontal and vertical casters. The process economises on both labour and time. The crucible can be 100% emptied out by casting horizontally, thereby saving precious metal ( in the traditional machine this is dumped as scrap). There is a drastic reduction in cooling time, thereby increasing the crucible life.
