Technical field
The invention belongs to metal powder preparation technical field, particularly a kind of preparation method of aerosolization glass putty tundish attemperator.
Background technology
Glass putty is widely used in diamond tool, friction material and other sintered metal products.Current topmost preparation method is air atomizing.Its technique is that tin slab is fused into liquid in change tin stove, then flow in tundish by tin liquor guiding device, tundish bottom is equipped with leakage eye, and tin liquor is from leakage eye vertical current, by the gases at high pressure of atomization spray dish ejection, liquid note is broken up, realize the object of powder by atomization.Wherein, in atomization process, in order to prevent tin liquor from cooling, must ensure in the temperature range that the temperature of tundish maintains higher than glass putty fusing point.This just needs a set of tundish attemperator to Tundish Heating, and attemperator conventional is at present generally gas heating type or electrical heating type, and gas heating type needs to consume a large amount of combustion gas, and cost is higher.And electrical heating type advantage of lower cost, operating environment safety, is generally used.
Current electrical heating type attemperator adopts resistance wire, silica crucible, heat-preservation cotton, iron plate etc. to be assembled, resistance wire is wrapped in outside silica crucible, and its shortcoming is that silica crucible is in use very easy cracked, and resistance wire also easily blows, change frequent, cost is higher.
For the deficiency of this device, the present invention adopts iron plate or corrosion resistant plate to make cylindrical crucible and substitutes silica crucible, is wrapped in inside cylinder by resistance wire, and with ceramic ring, resistance wire is fixed, at cylindrical outer side fill insulant material, and finally iron sheet on outermost cover.The advantage of this device is that Iron reutilization is sturdy and durable, and resistance wire not easily blows, and the efficiency of heating surface is high, cost-saving etc.
Summary of the invention
The object of the invention is to prepare a kind of aerosolization glass putty tundish attemperator, a kind of simple, durable and tundish heat preserving method that the efficiency of heating surface is higher is provided.
For achieving the above object, the present invention takes following technical scheme:
A preparation method for aerosolization glass putty tundish attemperator, its concrete steps are as follows:
The first step adopts iron plate or corrosion resistant plate to curve cylindric crucible, its upper end disc center drilling, and aperture is determined according to tundish outside dimension, and lower end disc bore size and tundish leak eye size and mate;
Second step is along cylinder axis to equidistantly opening multiple row circular hole on the sidewall of crucible of cylindric crucible, and often row circular hole number is wound around the number of turn according to resistance wire and determines;
3rd step pastes one layer of heat preservation cotton inside cylindric crucible, and to contact with cylindric crucible to avoid resistance wire and cause short circuit, its thickness is determined according to concrete instructions for use;
4th step is that the ceramic ring that each bolt sleeve two is staggered relatively inside cylindric crucible, fixes with nut with bolt through circular hole; Bolt is used for fixing heat-preservation cotton on the one hand, is used for fixing ceramic ring on the other hand;
5th step is wound around along ceramic ring space by resistance wire, and resistance wire is mounted in the space in two ceramic rings, swings to prevent resistance wire;
6th step is fixed by the cylindrical or square iron sheet outer casing of the cylindric crucible made, and fills heat-preservation cotton in space.
The thickness of iron plate described in the first step or corrosion resistant plate is 3mm ~ 7mm.
In described second step on the sidewall of crucible of cylindric crucible along cylinder axis to equidistantly opening 3 ~ 10 row circular holes.
In the circular hole of multiple row described in second step, each circular hole pore size is identical, and pitch-row is in the same size, and its size is determined according to tundish size and the resistance wire number of turn.
The shape of described ceramic ring has at least one side to be protruding, is convenient to form space, is wound around resistance wire.
Beneficial effect of the present invention is:
The attemperator of structure of the present invention can be prepared flexibly according to tundish size, and the efficiency of heating surface is high, durable in use, not cracky, is convenient to maintenance, reduces costs.
