Slag fluidity is important process in steel making for transportation of the slag from the converter to the slag dump yard. Slag splashing is practiced in many of the steel plants for improving the converter life. For better splashing effectiveness the fluid slag is saturated with MgO by adding Dolomite which makes ...
The present invention relates to prevent the free falling objects during lifting or lowering operations performed by load lifting equipments like Cranes, hoists, electrical Tackles, CDQ lifters, passenger Lifts etc. The invention more particularly describes PLC based free fall protection system and method for all lo...
Tap hole mass plays important roles in blast furnace cast house operation. Tap hole masses are unshaped refractory which are used to plug the tap hole of a Blast Furnace. Tap hole mass is a combination of different refractory materials, suitable binders and lubricants. The major functions of the tap hole mass are se...
The present invention relates to the use of nanocrystalline materials (CeO2, MgO and YSZ) based protective coatings on the steel refractories in order to achieve improved life of the refractories. The CeO2, MgO and YSZ nanocrystalline powders preferably MgO powder coating are coated on Steel Industry refractories by...
The technology of prediction of mass of carried over slag plus retained slag in refining vessel as well as the thickness of slag deposited on lance surface is described. The technology of on-line and off-line dynamic control of the refining process through the ratio of actual to theoretically predicted post combusti...
The invention relates to a process of making the briquettes from the coke dust fines generated in the Coke dry quenching (CDQ) process. These briquettes are to be used as a replacement of the coke in the Blast Furnace process in iron making for steel production. A significant amount of coke dust fines are generated ...
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...
ABSTRACT:
Title: Preparation Method of Low-Melting Ladle Flux from Ladle Furnace Slag for Treating Silicon-Manganese Killed Steels
The present disclosure proposes a method for preparing low-melting ladle flux with recycled stabilized Si/Mn/Al killed ladle furnace slag, reducing melting point and simultaneously inc...
ABSTRACT:
Title: A Method of Treating Si-Mn Killed Steels Using CaO and H3BO3 Fluxing Agents
The present disclosure proposes a method for treating Si-Mn killed steels using CaO and H3BO3 fluxing agents for reducing synthetic slag consumption, which result cost saving. In the present invention CaO based low melting...
