Abstract
The utility model discloses a furnace chamber for induction furnaces of power frequency and medium frequency, being composed of a furnace chamber body and a furnace chamber bottom; the furnace chamber body and a furnace chamber bottom are is shaped into an integral structure by pressing with a special die by fireproof material which is composed of magnesite or pulverized corundum, quartz sand, bauxite chamotte sand and other granules according to certain proportioning. The shape of the furnace chamber body is cylindric, the diameter phi of the furnace chamber body is from 250 to 700 mm, the wall thickness of an upper mouth is from 25 to 90 mm, the wall thickness of a lower mouth is from 25 to 90 mm, and the height of the furnace chamber body is from 400 to 1000 mm; the thickness of the furnace chamber bottom is from 40 to 200 mm. compared with rammed furnace chambers, the utility model has the advantages of convenient installation, safe utilization and high safety; electricity can be saved by about 15%, and the smelting time of each furnace can be shortened by about 20%.
Description
The utility model relates to a kind of furnace lining that line frequency induction furnace and medium-frequency induction furnace are used that is used for.
With line frequency induction furnace or medium-frequency induction furnace fusing non-ferrous metal aluminium, copper and alloy thereof, fusing ferrous metal such as molten steel, iron, steel alloy, stainless steel, smelting ferroalloy such as ferromanganese, ferrochrome, rare earth alloy etc. have the efficient height, quick heating, composition characteristics such as stir.But the furnace lining of power frequency and medium-frequency induction furnace is still continued to use traditional backward technology at present, i.e. ramming furnace lining in the induction body of heater.Ramming furnace lining not only labor strength is big, and labor condition is abominable, and take a lot of work, time-consuming, particularly the quality of furnace lining can not get guaranteeing, can only use continuously as the 250kg stove about 40 stoves, because furnace lining needs ramming again after having broken, influence deposite metal quantity, reduced production efficiency.
The purpose of this utility model provides a kind of replacing power frequency and medium-frequency induction furnace flue easily.Power frequency, medium-frequency induction furnace flue are by constituting at the bottom of internal furnace and the flue.It at the bottom of internal furnace and the flue one-piece construction.The internal furnace profile is the cylindrical of Φ 250-700mm, and wall thickness A suitable for reading is 25-90mm, and end opening wall thickness B is 25-90mm, and flue height H is 400-1000mm, and flue base thickness G is 40-200mm, and the flue capacity is 150-1000kg.
Power frequency, medium-frequency induction furnace flue are refractory materialss such as employing magnesia or emergy, quartz sand, bauxitic clay chamotte sand, by the certain granules proportioning, add an amount of wedding agent and additive, adopt non-sintering process, use particular manufacturing craft compression moulding.
The utlity model has following advantage, is example with the induction furnace of 250kg capacity:
1. economize on electricity 15%.Can directly send electric smelting without baker, the 160KW that uses when the electric power of induction furnace is by use ramming furnace lining in fusion process is reduced to 130KW, and does not influence liquid steel temperature and fusing time.
2. save time.Build a furnace lining, to the beginning melting, reduce to 1 hour by 8-12 hour of original ramming furnace lining and just can finish from construction, baker, and the smelting time of every stove shortening 20%.
3. easy for installation, safe in utilization, the life-span is long.After line frequency induction furnace and medium-frequency induction furnace were used flue, the replacing flue resembles the replacing machine, and part was so convenient in addition.Thereby reduced working strength of workers, improved labor condition.While to there being a filling bed to make safety liner between induction coil, has avoided wearing the stove phenomenon at furnace gall periphery, has therefore guaranteed production safety.
4. line frequency induction furnace and medium-frequency induction furnace use flue of the present utility model, can reduce the content of mechanical impurity in the molten metal, therefore can improve casting quality.
Fig. 1 is a structural representation of the present utility model, and the utility model is described in further detail below in conjunction with accompanying drawing.
Power frequency, medium-frequency induction furnace flue, by 2 constituting at the bottom of internal furnace 1, the flue, 2 is an one-piece construction at the bottom of internal furnace 1 and the flue.Flue capacity 150kg, the external diameter φ of internal furnace 1 is 320mm, and wall thickness A suitable for reading is 30mm, and end opening wall thickness B is 40mm, and the high H of flue 1 is 530mm, flue base thickness G is 60mm.
Capacity is that power frequency or the medium-frequency induction furnace of 150-1000kg can adopt the size shown in the following table with flue.Flue capacity kg Φ (mm) H (mm) G (mm) A (mm) B (mm)
150 250-350 400-650 40-80 25-50 25-50
250 300-400 500-700 50-100 25-60 25-60

1000 500-700 600-1000 80-200 40-90 40-90
Power frequency, the medium-frequency induction furnace manufacture method of flue is an example with the 250kg capacity:
1, batching.Refractory materials is selected electrosmelted magnesite clinker for use, granularity 0.05-8mm, and wherein coarse grain accounts for 65-80%, and powder accounts for 20-35%, adds suitable wedding agent and additive, puddles that to add water after 30 minutes an amount of, puddles evenly again.
2, moulding.The refractory materials of puddling is moved into compacting in the mould, the demoulding.
3, drying and thermal treatment.The flue base substrate of moulding is carried out drying and thermal treatment 1-3 hour at 60-600 ℃.
4, effect.Adopt the induction furnace of the flue of above-mentioned 250kg capacity, melting stainless steel is cut and the stainless steel waste material, needn't repair flue, can use 136 heats continuously.As a comparison, adopt the manually furnace lining of ramming in the induction body of heater, only can use 65 heats continuously, and the centre will repeatedly be repaired furnace lining.
