Description
Technical field
The present invention relates to pot base die casting preheating device technical fields, specially a kind of to be used for casting iron pan base die casting
The heating device preheated in the process.
Background technology
The press casting procedure of casting iron pan base is extremely important in the entire production process of cast iron cookware, and the pot base quality of die casting is straight
Connecing influences the yield rate of last cast iron cookware, and therefore, each key technology in casting iron pan base press casting procedure is crucial.
For metal from settable liquid at very sensitive to environment temperature during solid, the variation of different environment temperatures can cause metal
The variation of internal crystallization, to influence the certain physical characteristics of the metal after solidifying again.
The press casting procedure of casting iron pan base is after being definitely fused into molten iron, to be cast in die casting, carries out die cast
's.It before molten iron casting, needs in advance to preheat mold, die casting needs to be scalded in advance when in use
Mould just can guarantee that molten iron will not generate trachoma or crack when being poured into mold because of cooling suddenly, tradition
The mode of heating of casting iron pan base die casting be to scald mould after-pouring in advance by melting molten iron, and the molten iron for scalding mold is scrapped
It abandons, recycling cannot be repeated, although the preheating of this preheating method is very fast, there is also very more problems, one, preheating are used
Molten iron need in advance carry out fusing and whole process need operator to be monitored operation, expend a large amount of manpower and produce when
Between；Secondly, molten iron used in preheating with formal production when used molten iron be the same, and preheat the molten iron used and carry out
It is scrapped at random after scalding mould, cannot reuse, cause a large amount of wasting of resources, improve production cost indirectly, do not meet country
The environmentally protective requirement of energy-saving and emission-reduction, thirdly, molten iron high temperature, directly to carry out scald mould, be easy to cause mold surface temperature rapidly
It increases, and mould inside temperature ramp-up rate is excessively slow so that mold entirety uneven heating is even, is processed to be easy to cause mold
Casting iron pan base generate trachoma or crack, reduce yield rate.
Therefore, the demand of the heating device preheated in a kind of tool press casting procedure for casting iron pan mold of design just seems particularly
Urgently.
