The influence of sintering process parameters on the performance of iron-based parts Sintering process parameters: sintering temperature, sintering time, heating and cooling speed, sintering atmosphere, etc.
1. Sintering temperature
The selection of the sintering temperature of iron-based products is mainly based on the product composition (carbon content, alloy elements), performance requirements (mechanical properties) and uses (structural parts, anti-friction parts), etc.
2. Sintering time
The choice of sintering time for iron-based products is mainly based on product composition (carbon content, alloy elements), unit weight, geometric size, wall thickness, density, furnace loading method, etc.;
The sintering time is related to the sintering temperature;
The general sintering time is 1.5-3h.
In continuous furnace, holding time:
t = L/l ▪n
t — Holding time (min)
L— length of sintered belt (cm)
l — Length of burning boat or graphite board (cm)
n — boat pushing interval (min/boat)
3. Heating and cooling rate
The heating rate affects the volatilization speed of lubricants, etc.;
The cooling rate affects the microstructure and performance of the product.
