High frequency furnace burden is calculated as follows:

(1) the changes of high frequency furnace burden calculation of each element in the

A) the carbon content of molten iron charge: C% = 1.8% + 0.5 Ccharge%

Molten iron to the average carbon content of 3.4%, according to the type of C charge is%=3.2%;

B) silicon content of hot metal charging: the needs of theaverage content of silicon of 1.75%, if the silicon melting lossis 15%, then the

Si =1.75/ (1-0.15) =2.06% charge;

C) charge of manganese content hot metal melting loss of known Mn =0.65%, 20%, so the Mn charge =0.65/ (1-0.20) =0.81%;

D) sulphur content of molten iron burden of known S =0.12%,increases the sulfur 50%, are: S =0.12/ (1+0.5) =0.08% charge;

E) charge amount of phosphorus phosphorus no major changes in the melting process, P <0.25% =P hot metal charge

Integrated the above result, the required charge configuration for the average chemical composition:

C charge 3.2%, Si 2.06%, Mn 0.81%, charge charge S charge<0.08%, P charge <0.25%

(2) determine the initial high frequency furnace burden ratio

A) returns ratio: mainly depends on the rejection rate and the rate of finished products, it varies with the specific production. Here 20%.

The new iron and steel scrap ratio b): set the new iron for X%,then scrap as 80%- x%. According to the charge required carbon content is 3.2%, the new pig iron, scrap, scrap the carbon content of each is 4.19%, 0.15%, 3.28%, can list type:

4.19 x +0.15 (80- x) +3.28*20=3.2*100

Obtains x =60.0%. The iron material ratio: Z15 of pig iron,scrap steel, scrap 60% 20% 20%.

(3) high frequency furnace and then according to the proportionand various charge composition, calculation of charge componentssuch as table 3.

Table 3 charge composition

(4) high frequency furnace iron alloy addition amountcalculation

A) adding amount of this lack of silicon content in ferrosilicon0.67%, i.e. 100 kg per 0.67 kg of burden add silicon. Thesilicon content in ferrosilicon is 45%, so every 100 kilograms of charge must add the ferrosilicon weight of 0.67/0.45=1.5 kg

B) calculation ferromanganese added amount of the same method,every 100 kilograms of charge must join with 75% Mnferromanganese: 0.12/0.75=0.16 kg.

(5) high frequency furnace making the list of ingredients

According to the amount of iron ratio and layer, determine thevarious charge for each batch of charge weight, write a list of ingredients. A known layer of iron 500 kilograms, is composed ofeach batch of iron material: pig iron, scrap steel::500*60%=300 kg 500*20%=100 kg, scrap: 500*20%=100 kg, 45% ferrosilicon

The gear heat treatment, with much of the equipment to tell the truth, is affected by many factors in the selection, such as thediameter of the gear, tooth height, quenching speed. Choice ofcomprehensive individual customer gear specifications andequipment, we summarized some rules (see table below).

Equipment type selection of gear diameter

100mm 50kw/60kw

200mm 80kW

200-300mm 120kw

400-500mm 160kW

Well, look at the table, I think your work of the heat treatmentof high frequency induction heating furnace much, your heart has a general, however, small make up remind you not blindly to thetable as the standard, this table is only a reference, specificalso according to the actual the case may be, such astransformer capacity, you on quenching speed requirements etc..

Gear quenching as half shaft, shaft and so on so simple, it is affected by many factors. Most of the gear can select the overall quenching treatment, but if your gear teeth height more than 30mm, you need to select a single gear quenching
