Abstract
The present invention is one kind of reduction pot and its heat insulating method. The reduction pot is separated into three sections, including one inside-kiln pot body in the middle part and two outside-kiln bodies on two ends, and has heat insulating units of non-metal material set between the inside-kiln pot body and each of the outside-kiln bodies. The present invention has less heat loss, lowered material inlet and slag outlet temperature, improved work condition, high safety, high production efficiency and low production cost.
Description
Technical field
The present invention relates to a kind of heat-insulating method, particularly relate to a kind of heat-insulating method of jar and reduction tank for preparing by this method of reducing.
Background technology
Vacuum metal smelting reduction furnace structure is made of reduction jar, crystallizer and reduction furnace kiln body, present reduction jar is placed horizontally in the kiln body, and it is external that crystallizer is in kiln, by the feeding in the reduction jar of crystallizer mouth end, the other end is supported on the tank body by the intravital construction structure of kiln for sealing.The deficiency that exists is: the feeding amount is on the low side in the reduction jar, thereby makes reduction jar metal output capacity on the low side; The reduction jar of horizontal positioned exists charging inconvenient simultaneously, and labor strength is big, the not high problem of heat utilization ratio in the stove; Because the other end of reduction jar seals, after reduction reaction was finished, slag was to draw out from the crystallizer mouth, and labour intensity is big, the slag removal difficulty, thus influence productivity and improved production cost.In order to solve above deficiency, we improve original structure, on the kiln body, support is set, an end that the reduction jar is provided with crystallizer makes progress, the other end of reduction jar sets out cinder notch, and should hold downwards, tilting 3～60 ° to be placed in the support of kiln body, crystallizer and slag notch are in outside the kiln body.But,, also make charge amount be convenient to control though solved the problem of charging and scarfing cinder inconvenience because slag notch is located at outside the kiln body.But because the reduction jar is between 1000～1300 ℃ in temperature generally, the following environment of pressure 10～13Pa uses down, and the slag notch and the opening for feed that are in outside the kiln body can cause calorific loss to increase.Slag notch is in the condition of high temperature simultaneously, has increased the vacuum-sealing of slag notch and has opened the difficulty that slag notch carries out scarfing cinder.The workman at high temperature opens slag notch and carries out the scarfing cinder operation, is easy to take place the scald accident, makes very abominable that workman's working conditions becomes, and has had a strong impact on productivity, has also improved production cost.
Summary of the invention
The objective of the invention is to, a kind of heat-insulating method of jar and reduction tank for preparing by this method of reducing is provided.Big with calorific loss in the solution prior art, the temperature of reduction slag notch and opening for feed is improved workman's labor condition, prevents the generation of scald accident, enhances productivity, and reduces production costs.
Technical scheme of the present invention: a kind of heat-insulating method that reduces jar, the tank that will reduce is divided into three sections, a reduction jar middle part is a tank body in the kiln in the intravital part of kiln, reduction jar two ends are tank body outside the kiln in the external part of kiln, and the isolation section that non-metallic material are made is set between the tank body outside tank body and the kiln in kiln.
In the heat-insulating method of above-mentioned reduction jar, tank body is heat insulation outside tank body and the kiln in the bolt of isolation section through being with heat insulating mattress or instlated tubular and the kiln is connected.
In the heat-insulating method of above-mentioned reduction jar, isolation section is made with the corundum mould material.
A kind of reduction tank of the heat-insulating method preparation by reduction jar, reduction tank comprise outer tank body 3 three parts of kiln of tank body 2 and tank body two ends in the kiln at tank body middle part, are provided with the isolation section 1 that non-metallic material are made in kiln outside tank body 2 and the kiln between the tank body 3.
In the reduction tank according to the preparation of the heat-insulating method of above-mentioned reduction jar, tank body 2 two ends are provided with flange in the kiln, also be provided with flange on the outer tank body 3 of kiln, the bolt that isolation section 1 usefulness in the kiln between the outer tank body 3 of tank body 2 and kiln is with heat insulating mattress or instlated tubular 5 is connected on the flange of interior tank body 2 of kiln and the outer tank body 3 of kiln.
Compared with prior art, it is big to the invention solves in the prior art calorific loss, has reduced the temperature of slag notch and opening for feed, has improved workman's labor condition, prevents the generation of scald accident, has improved production efficiency, has reduced production cost.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the part sectioned view of isolation section;
Being labeled as in the accompanying drawing: 1-isolation section, tank body in the 2-kiln, the outer tank body of 3-kiln, 4-crystallizer, 5-heat insulating mattress or instlated tubular, the 6-end cap of slagging tap, 7-kiln body.
Embodiment
Embodiment: the heat-insulating method of reduction jar, as depicted in figs. 1 and 2.Its method is that the reduction tank is divided into three sections, and the reduction jar part of middle part in kiln body 7 is tank body in the kiln, and the reduction jar part of two ends outside kiln body 7 is tank body outside the kiln, and the isolation section made from the corundum mould material is set between the tank body outside tank body and the kiln in kiln.The high temperature that isolation section has been isolated tank body in kiln tank body heat passage to kiln outside reduces the slag notch of frequent dismounting and the temperature of crystallizer sealing place greatly, reduced the difficulty of sealing, makes the operation of sealing become easily and reliably.Tank body is heat insulation outside tank body and the kiln in the bolt of isolation section through being with heat insulating mattress or instlated tubular and the kiln is connected.Because bolt connects the high temperature reduction tank body that is located at kiln body middle part, therefore on bolt, be with nonmetallic instlated tubular and heat insulating mattress 5, prevent that bolt from forming thermal conduction.
Press the reduction tank of the heat-insulating method preparation of reduction jar, as depicted in figs. 1 and 2, the reduction tank comprises outer tank body 3 three parts of kiln at interior tank body 2 of the kiln at tank body middle part and tank body two ends, is provided with the isolation section made from the corundum mould material 1 in kiln outside tank body 2 and the kiln between the tank body 3.Tank body 2 two ends are provided with flange in the kiln, also are provided with flange on the outer tank body 3 of kiln, and the bolt that isolation section 1 usefulness in the kiln between the outer tank body 3 of tank body 2 and kiln is with heat insulating mattress or instlated tubular 5 is connected on the flange of interior tank body 2 of kiln and the outer tank body 3 of kiln.Connect crystallizer 4 on the outer tank body 3 of the kiln of feed inlet end, connect the end cap 6 of slagging tap on the outer tank body 3 of the kiln of slag notch end, just constitute a complete reduction jar.
