the structure characteristics of sintering furnace



According to the structure characteristics of sintering furnace could be divided into two types: vertical and horizontal, again by way of working can be divided into intermittent (each loading must stop the furnace) and continuous (loading without cooling) under two categories.The structure of the sintering furnace according to the heating mode in general can be divided into two categories, resistance heating furnaces and induction heating furnace, they are also of sintered body can be divided into direct electricity heating and indirect electric heating two forms, according to the different sintering temperature, sintering equipment can be divided into medium temperature sintering furnace (900-950 ° C) and high temperature sintering furnace (110-1700 ° C) two categories, according to the different protective atmosphere can be divided into air sintering furnace and the sintering furnace of hydrogen (such as molybdenum wire furnace, stainless steel tube type hydrogen furnace), vacuum sintering furnace, etc.This section mainly introduced the bell jar type vacuum sintering furnace tube, silicon molybdenum rods sintering furnace, furnace molybdenum wire.

the working principle of high temperature molybdenum wire sintering furnace


High temperature molybdenum wire sintering furnace working principle is: using three root corundum tube furnace tube, on each corundum tubes around the heating wire, heating element from the merger of dogan molybdenum wire twisted, heating through heat transfer between the product, in the first paragraph corundum tube on iron chromium aluminum nichrome wire winding, the second and third paragraphs corundum tube on molybdenum wire winding, ensures the furnace can work under high temperature 1400-1600 ° C, the product use the high temperature, a third of the total length of the stove products from low to high temperature, slow to prolong service life, should prevent the molybdenum wire furnace use too much electricity, cold room to heat up, slowly even.

thermal degreasing furnace


thermal degreasing due to simple, easy to control and become the preferred method of production.Thermal degreasing on industrial operations can be divided into the vacuum thermal degreasing and atmosphere thermal degreasing, vacuum thermal degreasing principle is: the injection of billet heating in a vacuum to the binder composition volatile or decomposition temperature, makes the adhesive thermal decomposition of state changes, into a gaseous substance removal.In low temperature, the binder low vapor pressure, realize the evaporation part removal, temperature rise to binder decomposition temperature, decomposition reaction, more binder removal.
