Tap hole masses are unshaped refractories which are used to plug the tap hole of a Blast Furnace. Different high temperature oxide based refractories are used in iron making and steelmaking processes and after a certain period of operation these refractory linings are broken down and discarded. These waste refractor...
Tap hole clay is used in blast furnace for closing tap hole. It is a mixture of six to seven ingredients. The clay contains coke, resin, pitch and wash oil apart from bauxite, silicon carbide, plastic clay. These raw materials are mixed together in muller mixer and used in blast furnace for tap hole closing. Tar is ...
The present invention relates to a transmission drive of main drive pulley, to drive traction motor, air compressor and radiator fan and more particularly to a modified transmission drive for providing variable loads on the transmission drive in the locomotive engine.
FIG:1
The slag dump car needed to be locked with the rail during the dumping operation to maintain its stability. The ergonomically designed locking mechanism facilitates in easy locking and unlocking of the slag dump car during its operation. The present device is helpful in the locking of the dump car to the rails in a ...
The present invention relates to the process for making the wire rods by maintaining the pinch power at the tail end of the bar to overcome the cobble problem. The pinch power (current limit) is increased exactly when the bar exits the finishing block so that the speed of pinch roll increases in the same ratio as th...
Minimization of crumbling is an important phenomenon in steel industry as it causes environmental pollution and also increases the handling costs of the slag obtained. The invention relates to a process of minimizing crumbling of steel slag by adding fly ash to the slag. Fly ash is a byproduct of Thermal Power plant...
The present invention relates to a process for effective modification of oxide inclusions by ferro alloys addition during tapping of the liquid steel coming out of the converter to the Ladle heating Furnace followed by calcium treatment. Steel cleanliness is mainly associated with inclusion engineering which emphasi...
