Description
Technical field
The present invention relates to high-speed steel field, more particularly, to a kind of high speed steel wire circulated air drying oven.
Background technology
High speed steel wire also known as air hardening steel or high-speed steel, though cooled down in atmosphere when meaning quenching can also harden, and very cutting edge of a knife or a sword
Profit.It is a kind of steel alloy of complicated, contains the carbide formers such as tungsten, molybdenum, chromium, vanadium.Alloying element total amount is up to 10
~25% or so.Its in the case of high-speed cutting produces hyperpyrexia (about 500 DEG C) remain to keep hardness high, and HRC can be more than 60.
Here it is the topmost characteristic of high-speed steel --- red hardness.And carbon tool steel is quenched and lonneal after, though at room temperature
There is hardness very high, but when temperature is higher than 200 DEG C, hardness just drastically declines, and is had dropped down to and annealed condition phase in 500 DEG C of hardness
As degree, completely lost the ability of cutting metal, which limits carbon tool steel make cutting element use.And high-speed steel
Because red hardness is good, the fatal defects of carbon tool steel are compensate for, can be used to manufacture cutting element.
The Technology for Heating Processing of high speed steel wire is complex, it is necessary to by a series of processes such as annealing, quenching, tempering.Annealing
Purpose be to eliminate stress, reduce hardness, make microscopic structure uniform, be easy to quenching.Annealing temperature is generally 860~880 DEG C.Quench
Because its poor thermal conductivity is typically carried out in two stages when fiery.(in order to avoid causing big thermal stress) first is preheated at 800~850 DEG C,
Then 1220~1250 DEG C of hardening heat, rear oil cooling are heated rapidly to.Factory uses salt stove heat.Because of internal group after quenching
Knit a part of (about 30%) retained austenite of also reservation and be not converted to martensite, have impact on the performance of high-speed steel.To make remaining Austria
Family name's body changes, and further improves hardness and wearability, typically to carry out 2~3 tempering, and 560 DEG C of temperature is incubated 1 every time
Hour.
(1) method for manufacturing：Generally using electric furnace production, high-speed steel was once produced using powder metallurgy process, made carbonization
Thing is evenly distributed on matrix in superfine small particle, improves service life.
(2) purposes：For manufacturing various cutting elements.Such as lathe tool, drill bit, hobboing cutter, machine hacksaw blade and require mould high
Deng.
In order to ensure the product quality of high speed steel wire, applicant the step of cleaning is additionally arranged before high speed steel wire annealing, and
And dried after the cleaning, it is ensured that surface cleaning of the high speed steel wire when annealing steps are entered, it is to avoid high speed steel wire is entering
Cause the degradation of whole high speed steel wire because being infected with impurity during annealing.For this applicant has been specifically designed for high-speed steel
The drying oven of drying of the silk after cleaning before annealing.
The content of the invention
Problem to be solved by this invention is, for above-mentioned shortcoming of the prior art, proposes improvement project or replacement
Scheme, it is especially a kind of to improve high-speed steel product quality, it is ensured that the improvement of H.S.S. production qualification rate or alternative.
To solve the above problems, the scheme that the present invention is used is as follows：A kind of high speed steel wire circulated air drying oven, its feature exists
