Kanishka Carbons Private Limited

About

We are one of the leading manufacturing unit of “CALCINED PETROLEUM COKE” (CPC) in North Bihar situated at village Papraur in the district of Begusarai having its Registered Office at “Champa Niketan” Marwari Mohalla, Begusarai. We had started our production in the year 1994 since then we have been supplying our product with entire satisfaction of our valued customers. We procure our basic raw material “Raw Petroleum Coke” (RPC) and other consumables like LDO, HSD & Furnace Oil (FO) from Indian Oil Corporation Ltd, Barauni Oil Refinery. The Plant is a “CALCINED PETROLEUM COKE” Unit. Calcination is a high temperature process in which volatile matters present in Raw Petroleum Coke (RPC) is driven out. The Calcined Petroleum Coke has a fixed carbon of 99.0% which is very suitable for Aluminium & Steel Industries and for Carbon Paste Plant also. The process of Calcination is carried out on a reducing atmosphere inside the Rotary Kiln at temperature of 1250 to 1350 degree Celsius. Thereafter the coke from the kiln is water quenched and air cooled inside the rotary cooler. At present we have two Rotary Kiln CPC unit having production capacity of 100 m.ton per day. The Unit is broadly divided into three sections:- Raw Coke Handling Section. Calcination of Raw Petroleum Coke. Calcined Coke handling and storage. Raw Petroleum Coke of different sizes is fed to the crusher through conveyor hopper. The coke is crushed in size less that 35 mm and is discharged below the crusher where from it is manually fed to bucket elevator for discharging in feed hopper provided on the combustion chamber. The coke is fed then to the rotary kiln. The kiln is preheated before starting the feed to 500 to 550 degree centigrade feed end 800 to 900 degree centigrade at discharge end and approx. During preheating process the kiln is kept rotating at the rate 0-3 to 05 RPM. On getting required temperature feeding of Raw Petroleum Coke is started and thus calcinations starts inside kiln and passing through the same it comes in rotary cooler. There these CPC are quenched with water and where from these are shifted by trolleys for storage and onward dispatch. This is the brief description of PROCESS of our product. At present our major customer is M/s. Hindalco Industries Ltd.Renukoot- (UP). We are supplying to this party since last 15 years. At past since 10 yearswe have supplied to M/s. National Alum. Ltd. Bhubneshwar (Orissa),M/s. Bharat Alum. Ltd. Korba (MP), M/s. Madras Alum. Ltd. (Tamil Nadu)and several other Aluminium and Steel Industries Like BSP, RSP,etc. We have also a successful Export business of our product. Our product is very suitable for manufacture of Carbon Electrodes, for use in Aluminum and Steel industries and also for manufacture of Carbon paste also. We are also one of the leading manufacturing unit of“CARBON PASTE”inNorth Bihar situated at village Papraur in the district of Begusarai having its Registered Office at “Champa Niketan” Marwari Mohalla, Begusarai. We had started our production in the year 2010 since then we have been supplying our product with entire satisfaction of our valued customers. We procure our basic raw material “CALCINE PETROLEUM COKE” Large Carbon electrode are used in the electrochemical industry in the production of Aluminum, Magnesium, Alkalis and chlorine; in electrothermal processes for graphite calcium and silicon carbides; and in manufacturing steel and some none ferrous alloys. Small electrodes are employed in electric are lighting and primary batteries. This term “Electrode” signifies application where the function is primarily conduction of current. The pitch binder, preferably in liquid form is blended with the filler in a sigma-bladed mixer or a high shear kneader of the Baker-Perkins or Werner Plainer type at a temperature well above the softening point of the pitch. For larger electrodes typical mixes consists of Calcined Petroleum Coke, varying in size from 1-2 cm or more to finder that #200 ASTM mesh, and 15 to 35wt % of coal tar pitch. The carbon paste or green mix may be compression molded or extruded to give products which are then baked at a gradually increasing temperature to maximum of 750 to 1250 degree Celsius depending on the end use. The green strength of carbon paste, both hot and cold, is important since on carbonization a strong dense structure free of cracks must result. Green strength depends on many factors-the nature and particle size distribution of the filler; mixing condition, extrusion/molding temperature and pressure; and the amount and properties of the binder Characteristics of the carbonized article are, in addition, a function of the heat-up rate during baking, the maximum temperature and the cooling rate. At present we have 500 m. ton production per month.
