Metallurgical Industrial Furnaces An industrial furnace is essentially a thermal enclosure and is employed to process raw materials at high temperatures both in solid state and liquid state. The principle objectives of an industrial furnace are (i) to utilize heat efficiently so that losses are minimum, and (ii) to handle the different phases (solid, liquid …
Read MoreHoists and Load Lifting Accessories Lifting and moving of heavy materials from one point to another point in a manufacturing plant requires the use of specialized machinery. Load lifting equipments make material handling easier for the working people. Crane is equipment for the lifting or the lowering a load, and moving it horizontally, in which …
Read MoreLoad Lifting Slings Slings are accessories used for lifting and transferring of loads with the help of cranes, telphers, or hoists. Slings enable in the activities related to create anchors, attach to loads, lift loads, pull loads, and lower loads. The dominant characteristics of a sling are determined by the components from which it is …
Read MoreBF Coke and its Role in Blast Furnace The raw materials for a blast furnace (BF) normally consist of three types of materials namely (i) metallic materials (sinter, pellets, and calibrated ore lumps or briquettes), (ii) fuels (coke, pulverized coal, oil, and natural gas) and fluxes (limestone, dolomite, and quartzite). Metallic materials, fluxes and coke …
Read MoreRefractory Lining of Coreless Induction Furnace In steel melting shops of low capacities, induction furnace is preferred as a convenient melting unit because of its high efficiency, low energy consumption, easy operational control, and good performance with various kinds of steel scrap. The induction furnace is an electrical furnace in which the heat is applied …
Read MoreRoll chocks in Rolling Mill Rolling mills for rolling of steel differ in many aspects with each other. The rolling mills are of different sizes and capacities. The mills roll steel materials of different cross-sections, sizes and qualities and in material conditions which are either hot or cold. The mills have different configurations and speeds …
Read MoreContinuous Casting Machines and their Types Continuous casting (CC) is a process of producing an infinite solid strand from liquid steel by continuously solidifying it as it moves through a CC machine. It is the predominant process route in a modern steel plant which links steelmaking with hot rolling of steel. In the CC machine, …
Read MoreRolling Mill Cooling Bed A rolling mill cooling bed is used for the uniform air cooling of the rolled materials (bars or profiles usually referred as ‘bars’) and transport it in a phased manner from the entry side of the cooling bed to its discharge side. It transfers the bars one by one to the …
Read MoreShearing Process and Shears Shearing is a simple process used for the cutting of metals. It is basically a metal fabrication process and is being used in rolling mills at several places for hot as well as for cold cutting of the steel material. Shears can be used to cut steel and other materials of …
Read MoreGuniting Refractory Maintenance and Guniting Refractories Guniting of refractory materials has evolved in importance with modern steelmaking technology, and largely because of it. Guniting was seen by farsighted steelmakers as the only practical means of maintaining the steelmaking furnaces, particularly of countering the grossly uneven wear sustained by the linings. The steel industry has invested …
