Description
Technical field
The present invention relates to the manufacture method of a kind of trolley type heating furnace assembly, specifically prepare trolley type heating furnace base plate
Method.
Background technology
Trolley type heating furnace be a kind of by workpiece heat to the equipment needing temperature.It mainly includes body of heater and chassis.Institute
State chassis to be made up of housing, refractory brick, electric heating element and walking mechanism.It is both provided with for carrying heated on the refractory brick of chassis
The base plate of workpiece.
At present, the base plate used in trolley type heating furnace is traditional drop-bottom.Traditional drop-bottom is by polylith
The steel plate of the casting heat resistant steels such as Cr17Mn13N or 2Cr20Mn6Si2N slaps together.The thickness of trolley type heating furnace base plate is usual
It is arranged on about 30mm, the limited strength at high temperature of the conventional backplane under this thickness, during use, often occurs that deformation (is stuck up
Bent) and the phenomenon that ftractures so that backplate surface out-of-flatness, affect workpiece into and out of.Meanwhile, by heat-resisting steel sheet and plate casting condition with
The chemical composition deviation effects of steel-casting, traditional base plate that use casting heat resistant steel obtains is commonly present relatively concrete dynamic modulus so that
Its antioxygenic property is less than the recommendation of corresponding trade mark heat resisting steel.Therefore, traditional base plate is in use easily generated granular
Oxide peels off so that it is lower thickness, so that the intensity change that drop-bottom is at high temperature is lower.It addition, traditional base plate
Being slapped together by plurality of steel plates, there is gap between adjacent two steel plates, the oxide skin that workpiece produces in heating process can be from
Leaking in the electric heating element in trolley type heating furnace in these gaps, these oxide skins run up to a certain degree in electric heating element
After, electric heating element short circuit can be caused, be now necessary for blowing out cooling maintenance, add the maintenance cost of trolley type heating furnace.
And, the process of blowing out cooling maintenance can increase the degree of oxidation of heated workpiece, thus affects heat treatment manufacturing schedule.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method preparing trolley type heating furnace base plate, uses the method
The base plate intensity at high temperature of system is higher, do not interfere with during use workpiece turnover, will not be thinning, it is possible to decrease car-type adds
The maintenance cost of hot stove, does not interferes with heat treatment manufacturing schedule.
For solving the problems referred to above, it is provided that above technical scheme:
The feature of the method preparing trolley type heating furnace base plate of the present invention is to comprise the following steps:
The first step, selection
Choose carbon steel plate, stand-by.
Second step, goes oil processing
Remove the greasy dirt on carbon steel plate surface.
3rd step, pickling
Utilize acid solution that the carbon steel plate after deoiling is carried out, remove the oxide skin on carbon steel plate surface.
4th step, helps plating
Utilize quickening liquid that the carbon steel plate after pickling is helped plating.
5th step, dries
Carbon steel plate after helping plating carries out drying and processing, and drying temperature is 110 ~ 130 DEG C.
6th step, soaks
Carbon steel plate after drying is immersed in hot melt aluminum liquid, and the temperature of hot melt aluminum liquid is 740 ~ 780 DEG C, keeps 9 ~ 11min.
7th step, cooling
Carbon steel plate after soaking is placed in air and allows its natural cooling, obtains trolley type heating furnace base plate.
Wherein, described carbon steel plate is GB/T 700-2006 type carbon steel plate.
Wherein, described quickening liquid is prepared by the zinc ingot metal adding 3 ~ 4kg in the industrial concentrated hydrochloric acid of every cubic meter volume, described
The concentration of industry concentrated hydrochloric acid is 32% ~ 36%, and described zinc ingot metal is the Zn99.7 zinc ingot metal in GB/T470-2008 zinc ingot metal standard.
Take above scheme, have the advantage that
Owing to the drop-bottom of the manufacture method manufacture of the trolley type heating furnace drop-bottom of the present invention sequentially passes through selection
Oleic acid is washed and is helped plating to dry immersion air cooling process so that the surface of finished product base plate " hangs " has gone up one layer of thin aluminum, and
Base plate the most at high temperature works so that drop-bottom upper aluminum layer is all the time in diffusion.Therefore, use the base plate of the party's legal system at high temperature
Under intensity higher, the phenomenon that will not deform during use (warpage) and ftracture, thus ensure that the flatness of base plate,
Workpiece can be passed in and out smoothly.Simultaneously as the protection of aluminium lamination, base plate in use its surface does not haves granular oxidation
Thing peels off, thus avoids its lower thickness, it is ensured that intensity.It addition, corresponding chi can be chosen according to the table top size of chassis
Very little steel plate is as raw material so that finished product base plate is one piece of imposite, it is to avoid polylith is pieced together and the problem that produces gap so that
The oxide skin that workpiece produces in heating process cannot fall in the electric heating element in trolley type heating furnace, it is ensured that electric heating element can
The most normally work, from without blowing out cooling maintenance, reduce maintenance cost so that heat treatment progress is protected
Card.
