The furnace cover has few energy consumption, long service life and convenient replacement and maintenance.
Description
The utility model relates to a kind of steel-making refining bell.
Existing steel-making is adopted jacket type structure or jacket type more and is built the refractory brick mixed structure by laying bricks or stones with the refining bell, and the characteristics of the bell of this structure are, energy resource consumption is big, and service life is short, keeps in repair consuming time many.
The purpose of this utility model is to provide a kind of calandria water-cooled steel-making to use the refining bell, and this bell energy resource consumption is few, long service life, and change, easy to maintenance.
The purpose of this utility model can reach by following measure: a kind of steel-making refining bell, by lid (1), exhaust fume collecting hood (2), exhaust fume collecting hood cover plate (3) is formed, each several part is linked to each other by sparge pipe (15) and forms integral body, lid (1) is formed by one group of compact arranged steel pipe (4) and 90 ° of elbows (5) and 180 ° of elbows (6) assembly welding, main-supply (7) and main water return tube (8) are arranged on it, main water supply adpting flange (10) is arranged on the main-supply (7), main backwater adpting flange (9) is arranged on the main water return tube (8).
The purpose of this utility model can also reach by following measure: described exhaust fume collecting hood (2) is to be formed by one group of compact arranged steel pipe (4) and 90 ° of elbows (5) and 180 ° of elbows (6) assembly welding, and branch road water inlet tube connector (13) and branch road water outlet tube connector (14) are arranged on it; Described exhaust fume collecting hood cover plate (3) is to be formed by one group of compact arranged steel pipe (4) and 90 ° of elbows (5) and 180 ° of elbows (6) assembly welding, has the lid of electrode hole shape, and branch road water inlet tube connector (13) and branch road water outlet tube connector (14) are arranged on it; Lid (1) is provided with observation panel, thermometric sample tap and door (11); Lid (1) is provided with material alloying mouth and door (12).
The utility model utilizes the recirculated water cooling bell in lid, exhaust fume collecting hood and the exhaust fume collecting hood cover plate, and energy resource consumption is few, under regular service conditions, can use 2 years to 3 years approximately, and be that jacket type structure or jacket type and brick are built more than 10 times of refractory brick mixed structure.Simultaneously because the utility model mainly adopts the steel pipe manufacturing, its main pressure-bearing weld seam is few, and principal weld all adopts banjo fixing butt jointing, and (banjo fixing butt jointing is under equal conditions the easiest enforcement in all welding point patterns, and the joint geometry that weld joint efficiency is the highest), so the frequency that breaks down is minimum, and in case break down, the easiest enforcement of maintenance, and similar fault generally appears in consuming time shortening, and the repairing time only is 1/4th of jacket type structure.In addition, the utility model steel-making is all adopted independent water supply form with refining bell consumable accessory exhaust fume collecting hood and exhaust fume collecting hood cover plate, changes simple and easy to do convenient and time-saving.
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is that the A of Fig. 2 is to view.
Fig. 4 is the structural representation of exhaust fume collecting hood.
Fig. 5 is that the A-A of Fig. 4 analyses and observe.
Fig. 6 is an exhaust fume collecting hood structure of cover plate schematic diagram.
The utility model is by lid 1, and exhaust fume collecting hood 2 and exhaust fume collecting hood cover plate 3 assembly weldings are assembled.Lid is formed (being generally circle) by one group of steel pipe 4 and 90 ° of elbows 5 and 180 ° of elbow 6 assembly weldings solid together that is arranged in together.One of centre is enclosed between the bigger steel pipe of caliber and is divided into two sections with water-stop sheet 17, and one section is the collection case that supplies water, and one section is backwater collection case.For on the backwater collection case main-supply 7, main water return tube 8 being arranged, main water supply adpting flange 10 is arranged on the main-supply 7, main backwater adpting flange 9 is arranged on the main water return tube 8.Be welded with on the lid 1 hanger 16 is installed, the refining bell is fixed on workspace (the refining bell after fixing can be done oscilaltion in the certain limit) by hanger 16 is installed.Needs according to steel-making on the lid 1 are provided with observation panel, thermometric sample tap and door 11, are convenient to monitoring steel-making temperature and sampling and observation steel-making state in the steelmaking process.Material alloying mouth on the lid 1 and door 12 are devices of being convenient to add alloy material in molten steel.
Exhaust fume collecting hood 2 and exhaust fume collecting hood cover plate 3 also are the group welding pieces that is become with 180 ° of elbow 6 assembly weldings with 90 ° of elbows 5 by steel pipe 4; Branch road water inlet tube connector 13 and branch road water outlet tube connector 14 are wherein arranged on the exhaust fume collecting hood 2.Exhaust fume collecting hood 2 concentrates fume centralized to chimney meatus transmitting smoke together; Exhaust fume collecting hood cover plate 3 one is the effect of playing lid, and it is the effect of playing electrode hole that another one mainly acts on.
Exhaust fume collecting hood 2 links together with exhaust fume collecting hood cover plate 3 and lid 1 can be by 15 fixations of sparge pipe (as this example), if sparge pipe 15 is metal hose then connects with the bearing pin wedge-type between the three.
During installation, bell is fixed on the fixed arm of oscilaltion within the specific limits, links to each other and get final product with main water supply adpting flange 10, main backwater adpting flange 9 with metal hose by hanger 16 is installed.Do not have when in place at ladle, bell is in high point, and after the ladle that fills molten steel was in place, bell fell, and covers on that steel-making gets final product on the ladle.
Bell is cooled like this: the water supply hose that is connected with water pump links to each other by water main's flange, cooling water passes through sparge pipe 15 to lid 1, exhaust fume collecting hood 2 and exhaust fume collecting hood cover plate 3 each road water supply water, get back to the return main through sparge pipe 15 again, get back in the cooling pond through the metal hose that links to each other with main backwater adpting flange 9, form water-flow circuit, water is taken away heat cooling bell and is achieved the goal in cyclic process.
