Abstract
The utility model relates to a punched box which relates to the technical field of ironmaking punched grain slag. The utility model is composed of a punched box body, an upper water inlet chamber arranged on the upper end of the punched box body, a lower water inlet chamber arranged on the lower end of the punched box body, a punched orifice plate arranged in the punched box body and a panel arranged on the top of the punched box body, wherein, the punched orifice plate is provided with an upper layer water nozzle, a lower layer water nozzle and a profiled orifice; the use of the punched orifice plate can guarantee a lower layer punched water flow to occupy more than two thirds of a total flow; an upper layer punched water flow controls water pressure and water quantity to guarantee the one-time granulation of slag-water slurry in the punched box; the grain slag can smoothly passes through the punched orifice plate and simultaneously avoids and is far away from a water pressure belt (0.08-0.12MPa) generating foam slag dangers. The utility model has the advantage of simple structure; the utility model can optimize technology system structure and thoroughly change the grain slag blocking phenomenon of an INBA punched technology system in the punched orifice plate of the punched box, and the energy consumption is half as large as that of the INBA punched technology system.
Description
Technical field
The technical scheme that the utility model proposed relates to ironmaking punching out grain slag technical field.
Background technology
The big blast furnace of modern ironmaking as 2500 cubic metres blast furnace of Ma'an Mountain Iron And Steel Co., Ltd, adopts the filtering method of rotary drum (INBA method) the punching out grain slag of introducing from Luxembourg morely.Find that in production practice the design of this system exists not enough, principal reaction is on cooling body and Punched box.The cooling body pipeline is long, and wearing and tearing for a long time add the unreasonable of Punched box punching out orifice plate design, cause the obstruction of grain slag in Punched box, and influence is produced.
Summary of the invention
Technical problem to be solved in the utility model is, designs a kind of Punched box, stops up with the grain slag that solves Punched box, and the flushing cinder water yield and hydraulic pressure are adjusted in control, reduce the total system energy loss indirectly, change to simplify system architecture, realize the normal continuous production of system.
The technical scheme of the utility model technical solution problem is: it by the punching out casing, be installed in punching out casing upper end last intake antrum, be installed in punching out casing lower end following intake antrum, be installed in the intravital punching out orifice plate of Punched box, the panel that is installed in punching out casing top forms, the punching out orifice plate is provided with upper strata water jet, lower floor's water jet and profiled holes.
The upper strata water jet is provided with two layers, and they are along the straight line uniform distribution; Lower floor's water jet is provided with five layers, last two layers along the straight line uniform distribution, following three layers along the camber line uniform distribution; The water jet diameter is 25mm, and its inwall is provided with ceramic layer; Profile hole is five, and one of them is arranged on the centre of upper strata water jet, and other is distributed in the outside of lower floor's water jet.
Owing to adopt technique scheme, can guarantee that lower floor's punching out current account for more than 2/3 of total flux, punching out current in upper strata participate in hydraulic pressure, water yield control, guarantee the granulation of slag-water slurry in Punched box, the dangerous hydraulic pressure band (0.08-0.12MPa) of slag be avoided and be steeped away from generation to grain slag can simultaneously smoothly by the punching out orifice plate; Use the utility model can optimize the process system structure, system compares with the INBA flushing technology, adopt flushing technology of the present utility model system, cooling tower and supporting pump thereof have been cancelled, pipeline saves 70%, thoroughly changed the grain slag latch up phenomenon of INBA flushing technology system at Punched box punching out orifice plate, energy consumption is half of INBA flushing technology system.
